Hello,
I'm french and I was in US for few month ... I bought and used an HTC One M7 Verizon with a prepaid card and everything was OK.
Now i'm back to FRANCE and i would like to use it with a French SIM Card.
The sim card is detected by the phone but the thing is that only work on Edge ... no 3G or 4G ... so i can call or received call with Edge but no way to go on internet as i don't have 3G.
The french sim card is 3G-4G ready ... is there something i can do on the phone configuration to have 3G/4G
Thanks a lot for your help
