Unable to connect to network with unlocked Samsung galaxy s2

[#1]

I have a giffgaff sim that works on my unlocked iphone, but does not work on my unlocked galaxy s2. It only lets me do emergency calls.

When I enter *#7465625* it tells me the phone is unlocked. It's running Ice cream sandwich and is rooted. 

Any help here would be much appreciated

Thanks,

Andy

 Hi  Andy ,

It could be that you just need the gg settings
                       -----------------
As it's an android phone , if you have access to WiFi go on to the Play Store ( android market ) download the ..... giffgaffAPN ,then run it ,

on the first screen you see it has numbers 1 to 4 , touch number 2 .( It says " add or change data settings " ).

On the next screen it has numbers 1 to 3 touch number 1 ....( It says " enable Internet and MMS ) ".

That will do everything for you .

Hope that helps .

Try *#06# and compare the IMEI it gives you with the lable under the battery

I have seen a lot of rooted and upgraded S2s with corrupted IMEIs

I thought that the gg app did not work on phones running ice cream sandwich.
