-5% on your 1st eSIMuntil November 30
A North America eSIM covers the United States, Canada and Mexico on one data profile, so it is the plan to buy as soon as your trip crosses a border. Staying in one country, a single-country plan does the job. Either way, you install it at home on Wi-Fi and it connects to a local network on arrival.
Key takeaways
- The Simsima North America plan covers the United States, Canada and Mexico on one profile; a single-country plan stops providing data once your phone joins a network across the border
- On the 3 September 2026 snapshot of the Simsima eSIM Price Index, data in the region cost a median of about $2.37 per GB, against $3.11 worldwide
- Near the border, a phone can connect to a tower on the other side, at Niagara Falls or between Detroit and Windsor
- Yellowstone and the Icefields Parkway between Lake Louise and Jasper have little or no cell coverage, whatever plan you carry
- The iPhone 17 sold in the US takes no physical SIM, and Google says US Pixel 10 models other than the Pro Fold are eSIM-only
One plan or three: deciding by the border you cross
The North America plan lists exactly three countries: the United States, Canada and Mexico. The networks it uses in each are named in the plan details, and the data allowance is shared across all three, so a week in Toronto and a week in Chicago draw from the same pool.
A US, Canada or Mexico plan covers only that country. It keeps working right up to the border, then stops providing data as soon as your phone joins a network on the other side. If your route stays in one country, that single-country plan is enough; if it crosses even once, the regional plan saves you installing and managing a second eSIM.
Travelers coming from Europe, Asia or Australia are the clearest case for a regional plan, because their home carriers usually bill all three countries as international roaming. For US travelers the answer depends on what their own plan already includes, which the FAQ below covers.
travel eSIM against carrier roaming, side by side — including the two cases where roaming still wins
Seattle to Jasper, New York to Montreal: two cross-border routes
The Pacific Northwest loop is one of the most common two-country road trips: Seattle, the drive north on Interstate 5 to the Peace Arch crossing, Vancouver, the Sea to Sky Highway to Whistler, then east to Banff and up the Icefields Parkway to Jasper. Over ten to fourteen days, navigation on long drives, hotel and park bookings, messaging and some photo uploads typically use 8 to 12 GB if you stream on hotel Wi-Fi rather than on the road.
On the East Coast, a classic route runs from New York up the Hudson Valley to Niagara Falls, across to Toronto, then by train to Montreal and Quebec City. Rail and cities mean more Wi-Fi and less driving, so 5 to 8 GB usually covers a ten-day trip. A third pattern adds Mexico by air rather than by road: a week in Cancún or Mexico City bolted onto a US trip. All three fit a regional capped plan; heavier users or anyone sharing a hotspot with a laptop should check the plan details for hotspot rules or look at the unlimited options.
Price per gigabyte in the US, Canada and Mexico
Prices sit below the global median and close to each other. On the 3 September 2026 snapshot of the Simsima eSIM Price Index, the United States was near $1.65 per gigabyte, Canada near $2.37 and Mexico near $2.55, giving a regional median of about $2.37 against $3.11 worldwide.
Because the three markets are so close, the country you land in barely moves the bill. What changes the cost is whether one plan covers your whole route or whether you pay twice: once for a country plan, and again for a carrier's daily roaming charge or a second plan after the border.
Border towers, Mexico's line registry and other traps
- Towers across the water: at Niagara Falls, in Windsor across the river from Detroit, and along the Washington and British Columbia border, a phone can pick up the network on the other side before you cross. A single-country plan then stops working; select a network manually, or carry the regional plan
- Mexico's line registry: since 9 January 2026 Mexican mobile lines must be linked to their owner's identity, so a Telcel or AT&T Mexico SIM bought on arrival asks for your passport. The regulator said visitors roaming on a foreign line did not need to register during the 2026 World Cup, according to Expansión, and a travel eSIM is a foreign line roaming in Mexico
- No North American phone number: a travel eSIM carries data only, so restaurant waitlists and services that text a code to a US, Canadian or Mexican number will use your home number or need a workaround
- Central America is not North America here: Guatemala, Belize, Costa Rica and Panama are outside this plan, so a route that continues south from Mexico needs a second plan
Signal gaps in Yellowstone, the Rockies and the Mexican backcountry
Cities and the interstate network are well covered in all three countries. The gaps are in the places visitors drive to. The National Park Service describes cellular service in Yellowstone as extremely limited, with towers serving Mammoth Hot Springs, Old Faithful, Grant Village, Lake Village and a few other developed areas, and warns that summer crowds can overload the network; texting is usually the most reliable way to reach someone.
North of the border, Parks Canada states that there is no year-round cell coverage on the Icefields Parkway, with limited service only at the Columbia Icefield from May to early October. In Mexico, the cenotes around Tulum and Valladolid and the Copper Canyon rail line between Creel and Divisadero have long stretches without signal.

Simsima recommendation
One plan across the US, Canada and Mexico
Simsima regional plans cover the border crossing on a single profile, without a daily roaming fee.
Installing the eSIM on an eSIM-only phone before you fly
Many phones sold in North America no longer take a SIM card at all. Apple's US specifications state that the iPhone 17 is activated with an eSIM and does not support a physical SIM, and Google's Pixel help notes that in the US the Pixel 10 and later, except the Pixel 10 Pro Fold, can only use an eSIM. For a travel eSIM that changes nothing, as long as the phone is unlocked.
- Check the lock: on iPhone, open Settings > General > About; "No SIM Restrictions" next to Carrier Lock means the phone is unlocked, as Apple's travel eSIM guide explains
- At home on Wi-Fi, install the plan: open the Smart Link from your confirmation email or your Simsima account on the phone itself and the eSIM installs in one tap (iPhone on iOS 17.4 or later, and Android phones); otherwise scan the QR code from the email: on iPhone, Settings > Cellular > Add eSIM; on a Pixel, Settings > Network & internet > SIMs > Add SIM
- Label the new line, for example "North America", so it is easy to find in Settings
- On landing, turn on data roaming for the travel line only: Settings > Cellular, tap the line, then Cellular Data Options > Data Roaming. With iOS 26, the iPhone may instead show a Turn On Travel eSIM prompt that walks you through the same choice
- Keep data roaming off on your home line to avoid your carrier's charges, and leave that line on if you need texts from your bank

Frequently asked questions
There is no single best one. AT&T, T-Mobile and Verizon, and the prepaid brands that run on their networks, sell prepaid SIMs and eSIM lines in carrier stores and big-box retailers, and their main advantage is a US number. The trade-off is buying it after landing, often with a setup built for residents. A data-only travel eSIM is installed before departure and works from the arrivals hall, but gives you no US number.
Yes, widely. Apple's [list of carriers that support eSIM on iPhone](https://support.apple.com/en-us/101569) includes AT&T, T-Mobile and Verizon in the US, Bell, Rogers and Telus in Canada, and Telcel, AT&T and Movistar in Mexico. That matters if you want a local line with a number; a travel eSIM is a separate data plan that sits alongside your home line.
Possibly not. [AT&T's eligible unlimited plans](https://www.att.com/international/canada-roaming/) include talk, text and plan data in Canada and Mexico with no roaming charges, though AT&T notes roaming speeds may be slowed. Check your own plan: a travel eSIM makes sense if your carrier charges a daily fee, slows data roaming, or if you are coming from outside North America.
Look for three things before paying: a plan page that names the networks used in each country, a clear refund policy, and a reachable support team. With Simsima, an eSIM that has not been activated can be refunded within 14 days, and support usually replies within 24 hours. Also check that your own phone is unlocked, which matters more than the provider for whether the eSIM works.
No. It lists only the United States, Canada and Mexico. Central American countries sit in Latin America plans, so a trip that continues south from Mexico needs a plan that names every country on the route, or two plans installed before you leave.
It is data only, so there is no US, Canadian or Mexican number for calls, texts or verification codes; you call through WhatsApp or FaceTime instead. Coverage depends on the networks in the plan details and ends where the networks end, in national parks and on remote highways. Hotspot use depends on the plan, and the phone must be unlocked.
