123 of these 134 plans were checked against the seller's own shop on 17 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 134 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.

Cheapest eSIM for Northern Mariana Islands: the numbers
As of 17 October 2026, 06:01 GMT, the cheapest eSIM for Northern Mariana Islands is ByteSIM with 30 GB for 10 Days at $55.90. That is $1.86 per GB, the best rate of the 134 plans we compare from 6 providers. 33 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for Northern Mariana Islands?
There is no single best eSIM for Northern Mariana Islands, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 134 plans on the numbers, as they stand on 17 October 2026:
- Best value overall ByteSIM, 30 GB for 10 Days at $55.90. That is $1.86 per GB, the lowest real rate of every Northern Mariana Islands plan we track.
- Best for a short trip Saily, 1 GB for 7 Days at $5.99. The cheapest ticket that still gives you at least 1 GB for a week or less.
- Best for a long stay MobiMatter, 12 GB for 30 Days at $22.99, $1.92 per GB. The best rate among plans that last 30 days or more.
- Highest daily cap on an unlimited plan ByteSIM, 30 Days at $99.90, full speed up to 3 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and ByteSIM did not pay to be named here.
Which mobile networks does Northern Mariana Islands have?
Saipan is well covered around Garapan, the hotel strip and the main roads. Tinian and Rota have service in the populated areas and little beyond them, and the northern islands are effectively uncovered.
- Docomo Pacific: Docomo Pacific is the largest provider across Guam and the Marianas and is the only operator offering mobile 5G in the territory.
- IT&E: IT&E is the other major operator, running 4G LTE across Saipan and the main populated areas after absorbing iConnect.
Travel eSIMs roam onto Docomo Pacific or IT&E. Both cover Saipan properly. Tinian and Rota are thinner on both.
Is 5G available in Northern Mariana Islands?
Docomo Pacific runs the only mobile 5G in the Marianas, with quoted speeds up to around 250 Mbps down, and it is limited to part of Saipan. Elsewhere you are on 4G.
How much data do you need in Northern Mariana Islands?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Northern Mariana Islands right now:
Are unlimited eSIMs for Northern Mariana Islands really unlimited?
Not always. 73 of the 134 plans above are sold as unlimited, and most of them carry a daily fair use cap. A further 3 plans are unlimited in a different way: one capped speed for the whole plan, shown next to the word Unlimited in the table. For Northern Mariana Islands the caps we can see published are 0.5 to 3 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $1.86 per GB from ByteSIM, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card at the airport in Northern Mariana Islands?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter for a tourist SIM card. Data for Northern Mariana Islands starts at $5.99 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Northern Mariana Islands eSIM
Pick the plan, not the brandThe cheapest rate in Northern Mariana Islands today is $1.86 per GB from ByteSIM, against a median of $2.78. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in Northern Mariana Islands is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network. Expect 4G.
Know what happens when it runs out33 of the 134 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is ByteSIM at $10.50.
Good to know before you land in Northern Mariana Islands
The Northern Mariana Islands is a United States commonwealth, and several US carrier plans treat it as domestic. Guam is a separate territory: a plan naming one does not always name the other, which catches out anyone island hopping between them.
Saipan International is the main gateway, with connections from Guam, Korea and Japan. As a US territory, some American plans already include it, so check what you have before buying.
If your trip includes Guam as well, check that both territories are on the plan before you buy. Diving and the northern beaches are where coverage stops, so download maps and dive site information before you leave Garapan.
Northern Mariana Islands Travel eSIM FAQ
Everything you need to know about using an eSIM in Northern Mariana Islands
What is the cheapest eSIM for Northern Mariana Islands?

Is eSIM available in Northern Mariana Islands?
Yes. We track 134 prepaid travel eSIM plans from 6 providers that work in Northern Mariana Islands. You need a phone that supports eSIM and is not locked to a carrier; most iPhones from the XS onward and most flagship Android phones from 2019 on qualify.
Do Northern Mariana Islands eSIMs support 5G?
The networks our plans use in Northern Mariana Islands currently run on 4G. That is enough for maps, messaging, video calls, and streaming in most cases.
Can I buy a Northern Mariana Islands eSIM online before I travel?
Yes, and you should. Every plan on this page is sold online and delivered by email as a QR code within minutes. Install it on wifi at home, leave the line switched off, and turn on data roaming for it when you land in Northern Mariana Islands. The validity clock on most plans only starts when the eSIM first connects.
Can I top up my Northern Mariana Islands eSIM if I run out?
Yes. 33 of the 134 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.

For a trip of days or weeks, usually yes. Data for Northern Mariana Islands starts at $5.99 for 1 GB on this page, with no queue, no shop and no passport handed over at a counter. A local SIM card can still win if you stay for months or need a local phone number.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
Does a Northern Mariana Islands eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.

Which Northern Mariana Islands eSIM gives the most data per day?
Of the plans sold as unlimited here, ByteSIM allows the most at full speed, 3 GB a day from $4.90. The smallest allowance on this page is ByteSIM at 500 MB a day. Every one of them is advertised as unlimited, and past the daily allowance the speed drops, often to 1 Mbps or less, until the next day. Check the allowance, not the word.
