Android phones can suffer from all sorts of problems over time. One problem that most of you know is that Calls aren't going through on my mobile phone. or directly I'm not receiving callsIn other words, someone might be calling you at that moment, but the call won't appear on your phone. So, you don't actually know someone is calling you, or you can't return the call when you need to.
This is not only annoying, it can also pose a serious problem in your daily life: medical appointments, work calls, SMS verifications, or banks trying to contact you. These days, many people only have a mobile phone and no longer have a landline, so being unable to make or receive calls It's like being practically cut off from communication.
Given this situation, There are a number of solutions we can try. When calls don't go through on my mobile phone or don't come in correctly. These are simple checks you can do yourself on any Android phone, without needing any technical knowledge.
Thanks to them, in most cases calls will again display correctly on your phone and you'll be able to use them normally, whether for incoming calls o outgoing callsIn addition, you'll also see what you need to check with your carrier, how to find out if it's the network, the SIM, the Phone app, or even a third-party app that's interfering.
Normally, when performing these checks everything will work fine on the deviceOften, not being able to receive calls is accompanied by the inability to make calls ourselves. This is something to keep in mind, as neither of these options might be available on your mobile phone at that moment. So, it's something to always check, for example, by calling another nearby phone from your number or asking someone to call you.
Check the SIM card and its physical condition.
Even if we don't get a notification that the phone isn't connected to the network or that a SIM card hasn't been found, it's a check we should perform at all times. In many cases It could be a problem with the SIMIt may be damaged, slightly displaced by a blow, or have dirt on the contacts.
The SIM card in your phone might be damaged, which could be why you're not receiving calls. The first thing we can try is... Remove it with the phone turned off and reinsert itOnce done, we turn on the smartphone to see if the problem has disappeared, something that often happens to many users when the fault is only due to a bad connection.
If you want to be sure, you can put said SIM card in another deviceIf you have an unlocked mobile phone nearby, you can check if the SIM card actually works.
- If the SIM works in the other phone, then it's not a SIM fault and the problem will have to be found in your phone.
- If it fails on both devices (it won't let you make calls, it won't receive calls, or it won't be recognized), we can be almost certain that it's a problem with this card and you'll need to request a duplicate from your operator.
The presence of dirt or dust in the SIM card slot or tray is something that causes these types of problems on Android. Therefore, it's important that we go to clean both the SIM card and the trayOften it's just accumulated dust that prevents us from receiving calls on the phone, or that causes the network to drop intermittently.
This is something that can be as simple as blowing on said card.in the slot or tray. Doing this helps remove dust. Cleaning the SIM card's gold contacts with a dry microfiber cloth is also helpful when cleaning the card. Be careful when handling these contacts to avoid damaging the SIM.
Once everything is clean, reinsert the card and check if everything is now working normally on your Android smartphone. If your phone is Dual SIM, you can also:
- Deactivate and reactivate the SIM From Settings > Internet and networks > SIM cards or SIM cards and mobile network.
- Swap the SIM card slot if your phone allows it, to rule out a problem in one of the slots.
If you use an eSIM, a useful measure is delete the eSIM profile and configure it again Following your carrier's instructions. And if, after these steps, the problem persists when you put the SIM in another phone, you most likely need a card replacement from your company.
Connection status, airplane mode, and quick restart
Another thing that also needs to be In these cases, what you need to check is the status of the mobile connection.The reason why calls aren't going through on my mobile phone might be as simple as the phone being in airplane mode or the network radio having "frozen".
It's possible that we've disconnected the phone from the network and forgotten to return it to its normal state afterward. With airplane mode active, It is impossible to receive or make callsBecause the phone isn't connected to the operator's network. This is something many users forget, so it's something to always check.
We simply have to slide the phone's quick access panel, making the gesture of sliding from top to bottom on Android. There we look for the option where it is indicated if the phone is connected to the network or if airplane mode is activeOn Android, we usually have an airplane mode icon:
- If the icon is lit up or blue, it means airplane mode is active.
- We tap on this icon to deactivate it and the mobile will reconnect to the network.
When airplane mode is deactivated, the phone re-registers with the mobile network. This means you'll be able to receive calls on your mobile phone normally, provided there are no other issues.
Furthermore, although it's not strictly a smartphone setting, it does It can be used to clear the cache and processes The simple act of turning the phone off and on is often enough to fix most temporary problems that occur on these devices.
Restarting your smartphone can often fix a memory error affecting phone calls. Simply turn off your phone and leave it. turned off for a few minutes and then turn it on. If turning the device off and on doesn't allow you to receive phone calls, the problem is something else and you'll need to continue with the remaining checks.
Coverage, operator signal, and network type
A common reason why calls aren't going through on my mobile phone could be that it has poor coverage at that timeIf you're in an area with poor signal or coverage, calls may not go through or may drop when they start. This isn't necessarily a problem with your phone or SIM card; you're simply in an area with weak or no coverage.
This can happen in rural or mountainous areas, inside buildings with very thick walls, underground garages, or elevators. In these places, it's common to see the signal icon with only a few bars or even a message indicating poor signal strength. “Emergency calls only”.
Additionally, you need to consider your phone carrier. As you know, coverage varies considerably depending on the carrier and the area you're in. Therefore, some people may experience different levels of coverage. a place barely have coverage or no coverage at all, due to your phone operator. This is something that can certainly have an influence in this regard.
An important detail is the preferred network type that you have configured. If, for example, your phone is forced to use only 4G/5G and that coverage is unstable in your area, you might have data but calls will fail if VoLTE isn't configured correctly. Many calls still go through 3G or 2G, so it's worth checking:
- Go to Settings > Mobile networks or Network & Internet.
- Access the SIM you use to make calls.
- Search Preferred network type and select an automatic option (5G/4G/3G/2G automatic or similar).
If you continue to have problems, you can run a temporary test by selecting only 3G/2G automatic and trying to make a call. If that works, the problem is most likely related to your operator's 4G/VoLTE network in that area.
In the case of being abroad, You have to choose a network operator in that country If your phone hasn't done it automatically, you can do this from the connections or networks section, under an option called Network Operator. There you can:
- Choose automatic selection, so that the mobile phone chooses the best available operator.
- Or manually select an operator from the list if the automatic option isn't working well for you.
This, combined with having Data and call roaming activatedThis will help us to have coverage in that country and be able to receive or make calls again.
Phone app, permissions, cache, and notifications
One must also take into account the possibility that there is some phone app problem that we are using on Android. If this application is malfunctioning, calls may not go through correctly or Don't look at the call on the screeneven though they are calling you.
In these cases, it is advisable to review several key points:
Phone app permissions and notifications
One of the problems that interferes with the Phone application is that it does not have the permissions required to access the call log or to display on-screen notifications. To verify:
- Go to Settings > Applications.
- Search the app Phone Number (or the calling app you use).
- Go to Permissions and make sure that it is allowed, at a minimum, Call logTelephone and Contacts.
- Also check out the section on Notifications and check that they are enabled, including the option to show pop-up or full-screen notifications for incoming calls.
If you're using an app other than the one on your phone (for example, third-party calling apps), check that It is configured correctly and that it has the necessary permissions. Otherwise, calls may come through but not be displayed correctly.
Clear cache and data of the Phone app
The Phone app may be stuck in a process, consuming too many resources, or have a corrupted temporary file preventing it from functioning normally. In this case, a very effective solution is clear cache of the application:
- Go to your phone’s Settings.
- Go to Applications or Manage applications.
- Locate the Phone app and tap it.
- Go to Storage.
- Press on Clear cache.
Clearing cache removes Temporary files which can be corrupted without affecting your personal data. If the problem persists, you could consider deleting the app's data as well, although in this case you might lose the Call History and specific settings of the Phone app.
Conflict with third-party applications
Another reason why call notifications might not appear on the screen is that there may be some conflict with third-party applicationssuch as call recorders, spam identifiers, or launchers (application launchers) that replace your system's interface.
If you have recently changed your launcher, installed a call recording app, or an anti-spam filter, it's a good idea to run these tests:
- Uninstall or disable temporarily disable the launcher or the suspicious app.
- Try again to see if the calls are coming in and are displayed on the screen.
- If this solves the problem, reinstall only trusted apps or keep the original launcher.
Of course, something as simple as reboot the phone This is something we should always try, as it could have been a specific error in one of the phone's or app's processes. Restarting the device ends all these processes, including the one where the error occurred, and then we can receive or make calls from the app normally again.
Special modes: Do not disturb, focus, and call screen
On many Android phones, in addition to airplane mode, there are special modes that affect call behaviorThey don't always block the call itself, but they can prevent it from ringing, vibrating, or even appearing visibly on the screen.
Do Not Disturb mode and focus modes
Do Not Disturb mode blocks all or most notifications, including call alerts On an Android phone, depending on your settings, calls may be coming in, but you won't notice because the phone isn't making a sound or vibrating.
To disable it on Android, you usually need to:
- Go to your phone's settings.
- Go to Sounds and vibrations > Do not disturb.
- Disable option Do not bother or review the permitted exceptions.
In some customization layers, such as those that include focus, rest, or work modes, you can have automatic rules that activate Do Not Disturb at certain times or in certain situations. Check that there are no automatic rules active features that silence calls when you need to receive them.
Call Screen and spam filters
Some Android mobile phones have a feature known as Call ScreenThis is a system that allows your mobile phone to preview the call you are receiving and can act as a filter so that you don't receive certain calls, especially from unknown numbers or numbers categorized as spam.
This feature has several settings that allow you to adjust how it blocks certain numbers that call you: numbers detected as spam, potential scams, or numbers not in your contacts. If you've set Call Screen mode to the most aggressive level, you're likely not receiving any calls. legitimate calls from companies, services, or even people that you don't have saved.
To adjust this, open the Phone app, tap the three-dot icon in the upper right corner, go to Settings, access the Spam section, and then Call Screen. There you can reduce the filter level or completely disable the function if you prefer not to risk missing important calls.
System update and network reset
Android system errors can sometimes prevent us from receiving calls or cause the internal network protocol to fail, even if everything else is configured correctly. While we can't directly fix code errors, we can search for a software update that they correct them.
Updating your mobile phone is quick, easy and free, and it's best to do it while connected to a stable WiFi network:
- Go to Phone Settings.
- Sign in System > System updates or similar section.
- Allows the phone to check for updates.
- If one is available, select Download and install now.
If you're already up to date and the problems persist, one of the most powerful and secure solutions is reset network settingsThis step:
- It doesn't delete your photos, apps, or contacts.
- Yes, it deletes saved WiFi networks, paired Bluetooth devices, and mobile data settings.
It is very effective for correcting network configuration errors that block calls or data. To do this, the usual steps are:
- Go to your phone's settings.
- Go to System > Reset options.
- Tap on Reset Wi-Fi, mobile data, and Bluetooth settings (name may vary).
- Confirm the action and enter the PIN or pattern if requested.
After restarting, try making and receiving calls. In many cases, this restores network stability and resolves persistent problems.
Problems with the operator, the line, and call forwarding
The problem might not be yours; it could simply be a problem in the company Or it could be a one-off fault on your line. Before considering hardware errors, it's always best to rule out these operator-related issues:
Operator outages and incidents
Whether it's just on your line or in general, your carrier may be experiencing an issue. network incident. To check:
- Ask other people with the same company if they can make or receive calls.
- Consult service monitoring pages, where maps of failures and peaks of reported incidents are displayed.
- Check your operator's official social media channels, where they usually post notices if there are widespread service outages.
If you confirm there's a general outage, all you can do is wait for the carrier to fix it. If the problem seems to be limited to your line, you'll need to check other areas.
Line blocked, restrictions or prepaid without balance
Some operators allow restrict incoming or outgoing calls (domestic or international), either from the client area or via short codes. A restriction may have been activated without your knowledge, for example, by dialing the wrong code or from the client website.
In addition, many operators offer the option of completely block the line In case of theft or loss of your mobile phone. If you or someone with access to your account has activated this block by mistake, you will not be able to make or receive calls until you deactivate it from the customer area or by calling customer service (from another line).
If your rate is prepaidWe cannot forget that running out of credit or exceeding the maximum period without recharging can cause:
- Inability to make outgoing calls.
- In advanced stages, even complete loss of line and of the number.
Check your mobile operator's app or call their balance information number to see if you have enough credit and if your line is still active. If you haven't topped up in several months, it may have been permanently deactivated.
call forwarding activated
Another function that you might have activated by mistake could be the call forwardingThis function, as its name indicates, sends the calls you receive to another phone, so your mobile barely rings or doesn't receive anything.
It's best to check that this option isn't enabled by mistake, as it could be the reason you can't receive calls on your Android device. You can check this in several ways:
- From Settings > Phone app > Call settings > Call forwarding, where you will see if any type of call forwarding is active (always, when busy, when not answering, when switched off or out of coverage).
- By entering universal codes on the keyboard, such as 002 ## # and pressing call, which usually deactivates all call forwarding configured on the line.
Also check your operator's customer area to see if there are any other call forwarding or rules set up that affect your calls.
Blocking, blacklisting, and problems with specific contacts
If the problem doesn't affect all calls, but only some some specific numbersThe most likely cause is that those contacts are blocked, either because you blocked them in the past or because a security app has identified them as spam.
On Android, the general steps for checking for locks are similar to these:
- Open the Phone app.
- Tap the three dots in the upper right corner to go to Settings.
- Look for a section called Filter Rules, Blocked Numbers, or Block List.
- Check which numbers are added and delete the ones you want to unlock or mark them as trusted.
If the problem occurs when you call someone and you hear a busy tone or an error message, it may be the other person who has blocked youIn that case, there's nothing you can configure from your end: you'll have to use another means of contact.
Network problems, roaming, and advanced diagnostics
If the quick settings you can check on your smartphone haven't helped, there are a number of other checks you can try on your own, both on the SIM card and the device itself, to pinpoint where the problem lies.
Pay attention to the coverage and the physical location
One of the most frequent problems is that we don't have coverage on our phone in a specific location: basements, garages, elevators, buildings with very thick concrete, etc. You may have perfect signal in other rooms or on the street.
If you're not receiving calls while at home, check if the problem is limited to one room (for example, the garage) or affects the entire house. If others on the same network are also experiencing poor coverage, it's a good idea to contact your provider or consider other options. change companies if the problem is persistent.
Data roaming and calls abroad
If you're traveling If you're not receiving calls, it's very likely because you haven't activated data and voice roaming. When you travel within certain regions, calls are usually included, but you must have roaming activated so that the mobile phone can connect to networks in other countries.
The path to activate it on Android, which may vary depending on the customization layer, is usually:
- Open Settings.
- Go to Mobile Networks, More connections or similar.
- Tap on Mobile Data.
- Find the section Data roaming.
- Enable data roaming on your SIM card(s).
Additionally, check in the SIM settings that the voice roaming It should be allowed, not just the data. Some operators allow separating it for tariff reasons.
Diagnosis: SIM card failure, operator failure, or mobile phone failure?
To go a step further, it is worth answering this question: does the problem stem from the SIM card, operator network or of own phoneA simple diagnosis can help you:
- Try your SIM in another unlocked phone.
- Try another SIM in your phone.
With these combinations:
- If your SIM card fails in another phone, but another SIM card works fine in your phone, the problem is most likely with the SIM card. your line or your SIM card.
- If your SIM works in another phone but no SIM works in your phone, the problem is most likely with the SIM card. hardware or software of your mobile phone.
In the first case, you will need to contact the operator so they can check your line, your balance, any blocks or configuration errors in their system, and if necessary provide you with a new SIM with your same number.
Technical service and potential hardware failures
If nothing works to solve this problem after checking the SIM card, coverage, special modes, Phone app, call forwarding, and network settings, we can always contact our operator or the technical service for the phone brandThere may actually be a problem with the phone's operation, such as a antenna failure or in the network module, and that it's not something we can repair ourselves.
Some signs of hardware failure are:
- The phone does not detect any SIM card, even after trying several cards.
- The antenna area gets abnormally hot when trying to make a call.
- The phone got wet or suffered a hard knock just before the problems started.
In these cases, it's up to an expert to take a look at the phone and determine what the problem is and whether it's necessary to carry out any repairs or component replacements.
If the phone is under warranty, said repair will surely be freeIn other cases, we may have to pay, which is almost certain when the phone's warranty has expired. If it's a very old phone, there are times when the repair might not be worthwhile, as the price could be very high. This is something you should always consider, weighing the cost of the repair against the cost of a new device.
It is also worth checking that the SIM card not physically damaged (bent, cracked, with burn marks) and that the tray is not loose or broken. Sometimes, a simple replacement of the tray or SIM card solves a problem that seemed much more serious.
When you have a mobile phone that won't receive calls or won't let you make them, that's when you truly appreciate the essential function that remains the core of any mobile phone: voice communication. With all the checks you've seen—from the SIM card and coverage, to special modes, the Phone app, network settings, and potential carrier issues—you have a a very wide range of practical solutions which in most cases restore your Android to normal operation without needing to immediately resort to technical service.
