Northern Mariana Islands eSIM
The Northern Marianas are a US commonwealth, and visitors concentrate on three islands: Saipan, Tinian and Rota. Saipan is a rental-car destination, from the hotels and restaurants of Garapan up to the northern cliffs around Marpi, while Tinian and Rota mean a short flight on a light aircraft whose schedule bends with the weather. Days here run on navigation and messages to dive shops and car desks, so it is worth deciding how you will be connected before you land.

How much data you actually need
A typical trip uses about 500MB to 1.5GB a day, because navigation stays open while you drive, on top of messages and photos. If you upload dive video every night, budget nearer 2–3GB a day, and add more when everyone in the rental car is on your hotspot instead of their own line.
When you land
The main gateway is Saipan International (SPN) at Chalan Kanoa on the south of the island, with flights from Seoul, Tokyo, Manila and Guam. Tinian (TIQ) and Rota (ROP) have their own airports, reached from Saipan on short light-aircraft hops. Get your line running at SPN, since picking up a rental car and confirming a hotel transfer usually needs you online as soon as you clear the counter.
Where coverage changes
Signal is best along Saipan's west coast, from Susupe up through Garapan to San Roque, which is where the hotels and restaurants sit. It thins in patches up north around Marpi, at the coastal caves and cliff sites, and on the climb to Mount Tapochau. Tinian and Rota have service around the main villages of San Jose and Songsong but drop out along the quieter ring roads. The islands further north are essentially uninhabited, and you should not count on coverage there at all.
Cities travellers ask about
- Garapan — Saipan's hotel, restaurant and street-market district.
- Susupe — Government offices and Lake Susupe, close to Saipan airport.
- Marpi — Saipan's northern tip, with cliffs and war memorials, and patchy signal.
- San Jose — Tinian's main village and the start of most drives around the island.
- Songsong — Rota's main village; quiet, with only a handful of shops and rooms.
Apps to install before you fly
- Google Maps with Saipan, Tinian and Rota downloaded before you drive
- Facebook and Messenger, used by dive shops and tour operators to confirm times
- WhatsApp or KakaoTalk for guides and transfer drivers
- A weather app to track typhoons through the wet season

Česta pitanja
How do I get from Saipan to Tinian or Rota?+
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.
What currency is used, and what licence do I need to rent a car?+
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.
Anything special to prepare when coming over from Guam?+
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.
When does a Northern Mariana Islands eSIM start counting days?+
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.
Do I have to remove my home SIM?+
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.
