Northern Mariana Islands eSIM

Normally on a light-aircraft flight from Saipan airport. The hop is short, but seats are limited and the schedule moves with the weather, so book ahead and reconfirm on the day, since changes are usually passed on by phone or message. Leave slack if you have an international connection the same day, and save the airline's number and your onward accommodation on the phone before you set out.

The US dollar, and most shops and hotels take cards normally. For car rental, each company sets its own conditions on foreign licences, international permits, minimum driver age and the credit card used for the deposit, so ask specifically when you book and keep the confirmation email available offline. Airport desks often open around flight times, and there may not be much room to fix a paperwork problem on the spot.

The Guam–Saipan flight is short and runs several times a day, but Guam and the Northern Marianas are separate jurisdictions, so confirm the entry requirements for your passport with the official authorities before flying. The same caution applies to connectivity: a package that lists Guam does not automatically include Saipan, so check the coverage areas named in whatever plan you are carrying before you leave.

Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.

No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
