I’m going to Saipan. I want to know if I can use my mobile phone’s data after I arrive? How to use wireless wifi?!! Help!!!

You can use it if you have opened the international roaming service, but the data roaming charges are very high, mainly because your operator needs to settle communication fees with the operator in the other region.

Wifi mainly needs to know whether there is a wifi hotspot in Saipan, such as a hotel, or the place you often go to. It may be a wireless LAN built by the shop owner himself, or it may be a wlan provided by the local operator. For services, you need to consult local people for this. Setting up on your mobile phone is very simple. You only need a username and password to log in.
