[fatua01]

I've bought a Galaxy note2 and when I returned to Europe 3g does not work, I've tried network mode: GSM / HSPA / LTE (auto conect), GSM HSPA (auto connect), only GSM, HSPA only, but only EDGE works . Model Number is SGH-I317M , the Android version is 4.3.
Please help me how to fix 3g?

You need to have all the setting to help u just told me 2 of them and when u set up or chose the one you need to back out and reboot .

That code will simply unlock your carrier specific phone. If that is what you have? But , it will only work on 4.1.1 He has given you the correct directions. You just need to try each one. Back out and reboot. Then try. Good luck..
