Z1s taking abroad, use foreign SIM
ok, I have a Xperia Z1s, which is a T-Mobile USA exclusive. unlike the International version, I can't just go to Settings -> Xperia -> Internet Settings (Download settings for Internet and MMS)
. then choose the SIM carrier network and installed.
I'm planning on taking my phone overseas soon, but if I don't install the correct internet settings, I only be running 2G, I assume. the country I'm going to have 3G and I been there before with other Xperia phones like L and Neo. Now if I were to go to Settings -> Mobile Networks -> Service Providers
and install the right network for the SIM, would it automatically works or do I need to manually type it in the APNs?
