eSIM for North America: The US, Canada and Mexico on One Plan
The simplest region to plan for and the easiest to overpay in. Three countries, good networks, and roaming add-ons that cost more per day than a week of travel data.
Dimitri MorvanNorth America is the simplest region to plan for and the easiest to overpay in. Three countries, good networks, reasonable prices, and carriers whose roaming add-ons cost more per day than a week of travel data.
Key Takeaways
- Only three countries are covered: the United States, Canada and Mexico. A regional plan is worth it if you cross a border, otherwise not
- Median data price is around $2.37 per GB, below the $3.11 global median
- The United States is the cheapest of the three at around $1.65 per GB, Mexico the most expensive at around $2.55
- Carrier roaming day passes across the border run $10 to $15 a day, several times the cost of a data plan
- Coverage is excellent in cities and along interstates, and genuinely absent in parts of the mountain west and northern Canada
What is the best eSIM for North America?
A single-country plan if you stay in one country, and a regional plan the moment you cross a border. Only three countries are covered, so the decision is simpler than elsewhere: data costs around $2.37 per GB at the median, while a carrier day pass for the same crossing runs $10 to $15 per day.
The Border Crossing Is the Whole Question
With three countries in the region, there is no complicated arithmetic. Staying in the United States, buy a US plan. Driving to Vancouver or flying to Mexico City as part of the same trip, buy the regional one.
What makes this worth stating is how expensive the alternative is. North American carriers sell cross-border roaming as a daily add-on, typically $10 to $15. A two-week road trip through the US and Canada on day passes costs more than most people spend on fuel, for data that a $20 regional plan would have covered.

What Data Costs
Below the global median, and unusually consistent for a region. On the 3 September 2026 snapshot the United States sits near $1.65 per gigabyte, Canada near $2.37 and Mexico near $2.55, giving a regional median around $2.37 against $3.11 worldwide.
Consistency matters more than the absolute number here. In most regions, the country you land in swings your bill several times over. In North America it barely moves, which means the plan structure, and specifically whether it covers your border crossing, is what decides the cost.
Coverage: Excellent, Then Suddenly Not
Cities, suburbs and interstate corridors are among the best served anywhere, with widespread 5G in all three countries. The exceptions are sharper than in Europe: parts of the mountain west, desert routes in the southwest and northern Mexico, and most of northern Canada have no service at all.
National parks are the case that surprises people. Yellowstone, Big Bend and much of the Canadian Rockies have little to no coverage inside their boundaries, whatever your plan. Download offline maps at the gateway town.
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.
If your trip extends further south into Central America, note that those countries sit in the Latin America plans rather than the North American one.

Frequently asked questions
With a regional North America plan, yes, all three from one profile. A single-country plan covers only the country it was bought for, and stops working at the border regardless of remaining data.
Around $2.37 per GB at the regional median on the 3 September 2026 snapshot, below the $3.11 global median. The United States is the cheapest of the three near $1.65, Canada near $2.37 and Mexico near $2.55.
By a wide margin on anything longer than a couple of days. North American carriers charge $10 to $15 per day for cross-border roaming regardless of use, while a regional data plan for a two-week trip typically costs about the same as two days of passes.
Often not. Yellowstone, Big Bend and much of the Canadian Rockies have little to no coverage inside park boundaries, and no plan changes that. Download offline maps and trail information in the gateway town before entering.
No. Guatemala, Costa Rica, Panama and their neighbours sit in Latin America plans. If your route runs from Mexico southward, check which plan covers the whole thing before buying, or expect to buy two.
