Some tablets include 3G connectivity as they have both the module and the SIM card slot. But generally, almost none of them allow receive and make calls. It's true that most tablets aren't exactly ergonomic enough to be used as a phone... but, given the possibility, it's a shame not to be able to use it (since, for example, with a Bluetooth adapter, the size issues disappear). However, other models, such as Asus Fonepad, they do consider using telephone functions in their design.
A model that offers this option is Samsung Galaxy Tab 10.1 3G, which has everything you need to be able to use it as a telephone but that the options of its operating system do not include the option of being able to make calls. A pity ... but there are options to solve this. The first is to use a ROM developed by third parties -not official therefore- of the many on the Internet that offer the option of using this tablet as a phone.
But we don't think this is the best option for many users, who prefer the Official Samsung ROM for stability and compatibility with the device. And this is where this short tutorial, which our colleagues at Redes Zona have published, comes in. in a few steps makes it possible to make calls on this Samsung model, as long as your operating system is Ice Cream Sandwich 4.0.4 (In this link to another blog you can see how to get this version of Android).
What do you need to activate calls on the Galaxy Tab 10.1 3G?
Before starting, it's a good idea to review the device's requirements and context. This tablet integrates a 3 Mb/s HSDPA 21G modem compatible with the 850/900/1900/2100 bands, uses a Mini-SIM card, and has stereo speakers, a microphone, and Bluetooth profiles with A2DP, so hardware isn't an impediment. Its platform combines a 2 GHz dual-core Nvidia Tegra 1 processor, 1 GB of RAM, and a 7000 mAh battery, enough for extended sessions. It also has Wi-Fi a/b/g/n, A-GPS, and 3.15 MP (rear) and 2 MP (front) cameras.
Software Requirements and Preparation: You will need to be in Android ICS 4.0.4 stock from Samsung, have installed ClockWorkMod Recovery, make a Backup complete and make sure the tablet has enough battery before flashing. Remember that any modification is made under your responsability.
Few steps to follow and easy to carry out
Apart from fulfilling the previous requirement, there is only one more necessary to be able to carry out the tutorial: having the program installed ClockWorkMod Recovery, which will be the one to be used each time an installation or similar is indicated.
By the way, since the ROM is not designed to make calls, it is important to know that when the tablet screen is turned off the call is cut off since the process is finished. In order to correct this there are two options: either you are careful to touch the screen before it turns off or, failing that, use a program such as Full Screen Control, in which activating the Active Call option and the PhoneUtil application should be able to correct this... at least, that's what they say at XDA Developers. Several users have observed that the cut usually occurs around 30 seconds, so it is advisable to adjust the screen timeout or keep it active during the call.
Here we leave you the steps to follow:
- Boot the tablet into Recovery Mode
- Make a backup in case you have any problems
- Install the ZIP file in this link (CWM_I9103XXLQ3_Modem.zip) as if it were a ROM
- Now install another ZIP, which you can get here (File Voice Call Enable ICS 4.0.4 ROM Build 1.zip) same as before
- Now you have to perform a Wipe of the cache and another Wipe of the Dalvik cache
- Restart the Samsung Galaxy Tab 10.1 3G
What to expect after applying the method
After completing the process, the tablet will display the telephony interface and you can make and receive calls Using the speakerphone, wired headset, or any Bluetooth hands-free kit. It's a good idea to test in different locations to verify 3G coverage and audio quality. Remember that, as this is not a feature provided in the ROM, there may be abnormal behaviors punctual (network registration, notifications or screen timeout).
If something doesn't work as you expect, you life jackets is the backup made from Recovery to return to the previous state. Similarly, repeating the Cache and Dalvik Wipes after installation helps avoid conflicts. And, for security, avoid installing multiple apps that modify the energy manager simultaneously.
