Hardware Version : V2

Firmware Version :

Has anybody had issues with the M5350 getting a 3G signal in the USA, I tried to configure an international sim with it recently in the USA and could never get a decent signal at all, could not get internet at all.
I was recently in Qatar and had a different hotspot device and it was excellent even in the desert we were getting 3G. Not so sure if it was my settings which were very difficult to config on this tp-link........

Any help would be great as I am going to China next week and need it to work.

Thanks,

Brian
