Unlock Verizon Galaxy S3 i535 as World GSM Phone - simplified method - GSM-Forum

kosta25 · 11-06-2012, 15:14

1.You need to root your phone if you want to have data conections if not skip this step.
How to root instructions you have here: [GUIDE] For beginners - Root Verizon Samsung Galaxy S3 SCH-i535/d2vzw - xda-developers

2.From Google Play store install the following apps if you do not have them: APN Manager Pro (81 Square), Phone Info (sc@taiwan), Titanium Backup Pro.

3 Turn off phone, pull out battery and put in micro SIM from your foreign country.

4. Use Phone Info app to change preferred network type "Global" or "Gsm only" (click on Device Information and scroll down to the first box to change). Some have reported that other choices were needed for their providers, so you may have to experiment.

5. Reboot phone. You should have the SIM card working for phone calls.

6. In Titanium Backup Pro, go to Backup/Restore, find and “long select” APN Manager Pro, and then select “Convert to system app”.

7. Open APN Manager Pro, select Insert APN, and input the data needed from your desired service provider.

8. Reboot phone. You should have the SIM card working for phone and data.

9. Remove notification "NON-VERIZON SIM" :
Using Titanium Backup, delete(uninstall) or freeze an app called Setup wizard 1.0 (its icon is a red check mark with a magic wand) and that should remove the notification

10. Enjoy.

i have a sprint gs3 so i am unable to join in on the fun but i'm wondering if anyone has tried using "test mode" to set to GSM and 850/1900 bands? Test mode is built into Touchwiz so... obviously this works in Touchwiz only. Press *#22745927 to enable hidden menus. then install Netmonitor from the Play Store. Open Netmonitor > hit the menu button > Hit "Field Test".

Once in Test Mode you can go to UMTS > DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL > BAND SELECTION to set GSM Band preference.

then starting at the very beginning over test mode again... CDMA > COMMON > NEXT PAGE > NEXT PAGE > PREF MODE SET to select GSM/WCDMA ONLY.

curious if someone could get ATT HSPA going using the above methods.. perhaps requiring even more test mode edits(poke around but be careful).

do this step and u will able to use any gsm network
