Pick a plan and buy it
Choose the amount of data that fits your route. Right after the purchase you get an email with a link and a QR code.
Set it up before you fly
Install the eSIM at home on Wi-Fi. After landing at New York (JFK), Los Angeles (LAX), Toronto (YYZ), Vancouver (YVR), Cancún (CUN) or Mexico City (MEX) there is nothing left to look for.
Turn on data roaming, done
Switch data roaming on for the new line and you are online. The plan starts with the first connection on the ground, and there is nothing to type in by hand.

North America eSIM: why one plan for the whole region leaves fewer leftovers than three country eSIMs
Roaming on your home contract is expensive on this route and hard to keep track of, because every provider sets its own daily rates and throttling limits. Three separate country eSIMs are no better: you pay three base prices, three minimum data bundles and three validity periods that keep counting down while you are somewhere else. Whatever is left on the Canada plan does not travel with you to Mexico. One eSIM plan for the whole region avoids that: you book 1 to 20 GB for 7 to 90 days and spread the data over the route yourself.
Then there is the moment at the border itself. That is exactly when you need the map, the booking confirmation and a translation, and exactly when a country eSIM would have you digging through your phone settings. On the usual routes this happens more often than people expect: Seattle to Vancouver, the drive to Niagara Falls, San Diego to Tijuana, or the onward flight from the US to Cancún. With this plan you simply connect to the next network and keep going.
Where coverage gets thin
In cities and along the major highways, North America is well served. Leave the main routes and that changes. Many national parks deliberately have very few masts; in Death Valley, across large parts of Nevada and Utah, in the Rockies around Banff and Jasper, and above all in northern Canada with Yukon, Nunavut and the Northwest Territories, you will have stretches with no signal at all. The same goes for the mountain regions of Mexico, long desert stretches in Baja California, and small towns off the toll roads. That is the state of the networks on the ground, not the eSIM: a card from the shop next door has no signal there either.
So plan for offline. Download maps for the leg while you still have signal or Wi-Fi, and tell someone which route you are driving. Do not expect 5G everywhere either, as 4G is the norm in rural areas. The eSIM does not work on ferries, cruise ships or in flight, where only the onboard network applies.
Data-only plan: no phone number, no calls and no SMS over the network. Your usual number stays reachable on your phone as long as you leave it switched on, and calls over WhatsApp, FaceTime or Zoom run on the data.
北アメリカで本当に必要なアプリ
These are the apps you actually need in the USA, Canada and Mexico, and for some of them the catch matters more than the app itself. Download Google Maps offline for your legs before you head into the national parks or across long desert stretches. Uber and Lyft are the usual way to get a ride in the US and Canada, in Mexico it is Uber and DiDi, and WhatsApp is the normal way to reach hosts, guides and drivers there. The catch: many US services expect a bank account and a phone number from that country, and in Mexico nearly every sign-up runs through a code sent by SMS. Set up anything that needs such a code at home, while your usual number still works.
Uber
Rides in all three countries, from New York to Toronto to Mexico City, with the price shown before you book.
Signing up needs a code sent by SMS. This eSIM has no phone number, so create the account at home before you fly.
DiDi
A widely used alternative to Uber in Mexico, and you can pay the driver in cash.
Mexico only, it does not work in the US or Canada. Sign-up also runs through a code sent by SMS.
Transit
Live bus, metro and train times for hundreds of cities in the US and Canada, plus Mexico City.
Small towns and national parks have no schedule data. Look up your route while you still have Wi-Fi or signal.
Rappi
Delivery app in Mexico for food, groceries and pharmacy runs, late into the night.
Sign-up often asks for a Mexican phone number, and foreign cards are sometimes declined. Paying cash at the door is the fallback.
Venmo
The normal way people split a bill in the US.
Needs a US bank account and a US phone number, so as a visitor you cannot register. Use a credit card instead.
GasBuddy
Shows fuel prices along your route, which adds up fast on long road trip legs.
It does not help in Mexico, so plan without it there.
