Solved: Samsung Galaxy SIII APN problems

Anonymous · ‎07-01-2014

I recently updated my Samsung Galaxy SIII (i9300) to a newer version of android. After I had updated I noticed I cannot use 3G, SMS messaging or calls. I presume there is something wrong with the apn I'm assigned to so I searched up the correct o2 pay monthly apn, I found that the correct one is mabile.02.co.uk so I went to check that I was using that one but when I opened the 'Access Point Names' menu I found that there were tow mobile.02.co.uk apn's (Neither of these seem to work) does anyone know how to fix this? Because at the moment I cant use my phone as a phone.

Flash MK6 with Odin.
It will remove root anyway and is the safest method of restoring your phone to stock.
Download MK6 from here http://www.sammobile.com/firmwares/ (type i9300oxa in the search box and MK6 is top of the list).
Then follow the Odin flash guide I wrote here http://community.o2.co.uk/t5/Android-Devices-Samsung-HTC-Sony/HOW-TO-A-Guide-to-using-Odin/m-p/46346...

Delete both apn's then text the word "active" to 2020. Save and apply the settings that get sent back to you....

Did you hard reset the phone after the update?

You don't need the APNs to use calls and texts, it should connect to the network by itself.

there isnt a 'reset all user data' or similiar option on my bootloader. i can do stuff like wipe delvik cacha and format data but i presume i dont need to do that because wiping delvik cache shouldnt be nessacary

First off it sounds like sim has failed or phone has dropped the IMEI number 😞
Does your IMEI start 00499 by any chance ?
If you have the option in your bootloader to wipe dalvik it means phone is rooted and I am guess you didn't know about this either?
