Okay, I have updated my S3 to JB and I see that my phone network mode is set to "Global". Is there any reason I should keep that as my default since I do not have any plans on going to another country. My other choices are "LTE/CDMA" and GSM/UMTS". Obviously since this is a Verizon phone if I were to change I would go to "LTE/CDMA". If I switch would it help the battery life?

Wondering the same. Noticed that it switched to global mode after the update. I switched back to LTE/CDMA, but not sure if I should have left it in global mode.

If y'all plan on staying here in the USA canada or mexico you can go to lte/cdma....gsm/umts will do nothing for you so global is useless...when u have no signal it will search for cdma and gsm if you are on global so more batery drain

Thanks that is what I suspected.

Also, since an option is GSM/UMTS does that mean if I switch to ATT or any other GSM service that my Verizon S3 would work if I got the proper SIM from the new supplier?

Not sure if they unlocked it or not with the update...i know when they updated the droid razr to global they also unlocked the sim but i dont think they let other gsm USA carriers sim cards work...thats just what i remember so hopefully it was helpful

Updated to JB last night. Really nice. Then this evening, started receiving this popup:

Turns out, I was set to Global and didn't know it! As previously stated:

Settings - More Settings - Mobile Network - Network Mode

I changed it to LTE / CDMA

Hopefully I won't see that popup again and the slight battery drain I've noticed will disappear.
