Three - Feel at Home – Roaming in US
Phone: Samsung Galaxy Note II N7105
GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 900 / 2100 - N7105
LTE – Irrelevant – N7105 doesn’t support US LTE
When traveling to US you are able to roam on AT&T and T-Mobile networks.
If your phone doesn’t have 1700Mhz band (most phones do not) you will not get 3G signal. This is a tutorial how to force your phone into 3G.
Three preferred roaming partner is T-Mobile. T-Mobile 3G runs on 1700Mhz band and phone will not have 3G signal, because 1700Mhz is not supported by most European phones. Phone will always get stuck on 2G. If your phone has 850Mhz 3G band you can get 3G by roaming on AT&T, but it will not happen by itself. You need to set your phone into 3G/WCDMA mode only and turn off 2G radio completely. At this point phone will only see AT&T network and register on it. Setting AT&T as preferred with 2G on doesn’t always work and phone eventually switches back to 2G T-Mobile.
