They said WhatsApp calls were finally here . And that was partly true. However, it was later revealed that to use them, you needed to be called by a user who already had access to the feature, as an invitation. Now we'll explain how you can activate WhatsApp calls without an invitation and what you should keep in mind to ensure they always work reliably.
You don't need an invitation
With this system, you'll be able to activate calls on WhatsApp , and you won't need an invitation to access them. Keep in mind that feature availability may be rolled out gradually from the servers . What does this mean? If the feature takes a while to appear, it's not a bug ; the rollout may be in progress. Once it's active on your account and device, you'll see the Calls tab and the phone icon in every chat. If, in the future, invitations are required again for specific tests, you won't need one with the current steps.
What do you need?
Current recommended method (no invites or root)
These days you don't need root access or to edit internal files. Just make sure you follow these steps:
- Update WhatsApp from Google Play or the App Store. If you don't see the option, use the official download from the WhatsApp website.
- Open the app and verify that the Calls tabIf you don't see it, close and reopen the app or reboot the phone.
- Check the permits: Grants access to Microphone, Phone, Camera (for video calls) and bypasses restrictions battery/data saving.
- Test under Stable Wi-Fi First, then, in mobile data, confirm that your operator does not limit the VoIP.
Classical method (technical reference only; not recommended)
The method described below belongs to an earlier stage when the feature was in testing and required root access and editing of device preferences. It is retained for informational purposes only. It is not necessary for current versions and may compromise the stability or security of your device.
For this, you only need a specific version of the app, which is 2.11.536. The best way is to download and install it directly from APK Mirror on your smartphone . You'll also need a rooted smartphone and a root file explorer, such as ES File Explorer. It only takes a few minutes, as it's a very simple process. Let's get started.
1.- Clear the cache and close WhatsApp
First, and in this order, you'll need to clear the app's cache , and then force close WhatsApp. You'll perform both actions from the same place. Go to Settings, then Apps, and find WhatsApp and tap on it. You'll see several options, but the one you're interested in first is related to the cache. Look for the Clear cache button [1] and tap on it. Next, find the Force stop button [2] that appears at the top of this window.
2.- File Explorer
It's time to locate the file you'll need to edit. To do this, launch ES File Explorer. First, you need to enable Root browsing . To do this, click the button in the upper left corner [3] to open all the application's options, then go to the Tools tab, where you'll need to enable the Root Explorer [4] and Show Hidden Files [5] options.
3.- Files to edit
To locate the file to edit, you'll need to go to the root directory of your smartphone. Simply tap the root button in ES File Explorer [6] . If you don't see it, navigate up through the folders until you reach the bottom. Then, go into the data folder [7] , then back into the data folder [8] , and look for the com.whatsapp folder , almost at the very bottom. Inside, open shared_prefs [9] , and then open the com.whatsapp_preferences file [10] , which might have a similar name on your smartphone, but with the same beginning.
4.- Enter the code
Clicking the button in the upper right corner will bring up the Edit option . With the file in edit mode, you need to find the <map> tag that appears in the first few lines, and right below it write the code shown in the image below [11].
Finally, tap Back, and the app will ask if you want to save the file . Confirm, and without doing anything else, turn off your smartphone.
5.- Turn on the smartphone
Simply turn on your smartphone to see that the call function is now activated . You'll know because the app displays three tabs: Calls, Messages, and Contacts, and because the call icon appears in each conversation with each contact. If you can't make a call when you tap the icon, wait until the service is fully operational on your account or use the recommended method.
How to activate them today without an invitation (quick steps)
If you don't see the Calls tab, try this sequence: update the app , force close it, clear the cache (without clearing data), restart your phone, and open WhatsApp connected to a stable Wi-Fi network . Check microphone permissions and disable data saving restrictions . In many cases, this is enough to make the feature appear automatically.
Cost, consumption and quality of calls
WhatsApp calls don't have a direct cost , but they do use up your data allowance. The approximate data consumption per minute is around 485 kB . For comparison, Messenger can use around 370 kB and Hangouts can exceed 500 kB . If you have a limited data plan, prioritize Wi-Fi or use your voice minutes when you're out and about.
Quality depends on coverage and network. WhatsApp adjusts the codec to optimize voice on unstable connections, but a weak network can cause dropouts or echo. On stable networks, audio is clear with low latency; for important conversations, always choose Wi-Fi.
Operators, coverage and possible limitations
Some budget plans from certain carriers may restrict VoIP . If your calls aren't connecting over mobile data, check your plan's terms and conditions or enable the feature only over Wi-Fi . You'll also need 4G/5G coverage or a good 3G signal; in areas with frequent outages (e.g., subways), calls may be dropped.
Remember: If your connection drops, the call will automatically disconnect . Once your internet connection is restored, you can resume the conversation by calling back.
