[Q] Unlock / valid sim OS upgrade Galaxy S3 (Verizon, Family Mobile)
I was wondering if someone could help me or point me in the right direction to avoid bricking my phone somehow.
First off, a bit of confirmation
for anyone else out there... I have successfully moved my Verizon Galaxy S3 to Walmart Family mobile. Currently trying to (safely) rid myself of annoyances.
Bought a new device via ebay with clean ESN for Verizon (I'm unsure if it's still locked to Verizon network, see below for details)
None of the suggestions like *#1973 ... worked as my phone was on a 4.0.1 release (or so I think) I don't see any websites that would offer and unlock code and I read somewhere that the manual unlock needed something like 4.1.x or higher.
I used Odin to upgrade my device to 4.1.1 (Still couldn't find any unlocking info but..
Inserting my Family Mobile SIM card actually works
(for calls and SMS) but the device still complains that it has a non-valid sim for Verizon. Going in to the Apps menu and killing the Setup Wizard 1.0 removes that message until the next reboot.
Optimally, I'd like to upgrade from 4.1.1 to 4.3 but have a few concerns.
Will an update rid me of the Verizon sim check? or is the sim checking piece not in the ROM but actually inside the bootloader itself?
I'm not highly technical (but dangerous enough I suppose).
When all is said and done I'm looking to have a 4.3 device with a Family Mobile APN that works (so far I don't believe that's occurred. Device is nice under wifi and says that cellular data is 'active' but I don't think it's working
since I can't hit websites in cellular only mode.
Any suggestions for getting my device to a happy place without rooting it would be appreciated.
