Samsung Galaxy S4 i9506 : GSM/WCDMA problem - GSM-Forum

OneAmine · 04-18-2014, 01:54

Hello,

My Samsung Galaxy S4 i9506 is 4.2.2 Jelly Bean.
He can't register to 2G (GSM), so my SIM works only on 3G (WCDMA).
SIMs without 3G activated can't be used in this phone

I tried my SIM on other phone, it's work perfect.

How to fix it ?

Thank's

for the moment this model is hard to fix that you shouldn't unlock with z3x or any dongle cause will damage modem, the best way is to buy unlock codes,, first search the forum for users experiences, then do the job,, is the best way
