SIM Number Changer
================

App to change the number registered in SIM card. This uses Xposed framework (http://forum.xda-developers.com/showthread.php?t=1574401)

After you have installed Xposed framework, install this app, open it, insert your number and click the button to change it. After that enable the mod inside Xposed Installer (you probably have a notification to do it (like you can see in image), you can click it) and restart your phone, insert your PIN and it should be done, you can open the app to confirm.

This was made for Samsung Galaxy S3 and tested on it. It may work on others phones, but I can't be sure. I don't held any responsibility for any damage you do on your phone.

Source code: https://github.com/OXINARF/simnumberchanger
Download (v1.2): View attachment SIMNumberChanger-v1.2.apk

NOTE: This app doesn't change your actual number, it just changes the number registered in your SIM card, many operators don't put number in there, but some apps (usually security ones) use the number registered there. In About section in Definitions it also appears the number registered in SIM.

Wow! Are you sure that's legal?
And I don't really understand, it mean that if I call a friend after changing my number, he will see the fake number?

If yes, incredible work.

PS : Which apps use the number? A little list could be cool :).

I'm sorry, didn't understood your question, can you try to explain better?

I think all it does is change the number that gets displayed in the about phone menu

As JDogg1329 said this just registeres a number in your SIM card (which appears in About section), but it doesn't change your real number (as stated in OP), so when you call a friend it still will display your real number. That, as to my knowledge, is impossible to do, because your network knows what number belongs to your SIM card.

I don't have a list of apps. I started working on this when I registered in Samsung Dive and it had my number empty. It also bothered me that it didn't appear in About section and there were people asking for this in Q&A forum. At first I couldn't do it, but now, as a personal project for making a Xposed mod, I've made it came to life and share it for anyone who wants it.

Well it should work since I'm using Android methods to do it. Problem is that I also use a specific class that is present in Samsung roms. As you seem to be using AOKP rom, that's probably the issue. Can you post debug.log that you can find in /data/xposed/ directory?

Waaait. Im kinda confused with what the app's purpose xD

I guess its just to hide your real number from apps that has phone permissions and can see your number??

It could do that for sure. But I'll try to explain a little bit better (although it will get a bit technical):

- you go to an operator and buy a SIM card. That SIM card has a unique number itself (just like our phones have an IMEI) and the operator gives you a phone number (which people use to call you).
- your operator associates your SIM card number with your phone number in their databases
- your SIM card could have your phone number registered in it or not (it depends on operator). This app allows you to register a number there. Is this really useful or needed? No, and because of that many operators don't register the phone number into the SIM card. But I prefer to have it there and it seems other people prefer it too.

You can read Wikipedia about MSISDN (which is what this app sets): http://en.wikipedia.org/wiki/MSISDN

I actually have discovered that my S3 is not showing the number correctly in the about menu. Only area code is correct and then the rest are just 0000000.

This is after you've used this app or before?

I don't know that app, but this app won't make you bypass network lock.

good job.

is possible hook to change mcc, mnc or SimCountryISO?
I don't know any method to do it, but I can't say it's impossible. But why do you want to do that?

After using it you can uninstall. I've made, used and uninstalled it. It should be registered in SIM so if you change your SIM to another phone it should have the number in it. If it isn't please report and I'll see what I can do.
