In summary: an eSIM for the USA and Canada gives you mobile data in both countries with a single plan: when you cross the land border, your phone automatically connects to the local network, without needing to adjust settings or buy anything new. It's installed before you fly, activated upon landing, and helps you avoid roaming charges from your Spanish carrier.
If your route combines New York with Toronto, or Seattle with Vancouver, buying two separate eSIMs is extra work: two QR codes, two balances, and remembering to activate the second one just as you cross the border (which is usually at the worst moment, with your hands full and the rental car honking behind you). With a regional plan, you forget about that switch. Here you'll find real operator coverage, how many GB to take depending on the type of trip, when a joint plan truly pays off and when it doesn't, and the step-by-step activation process.
A single eSIM for both countries
A regional eSIM for the USA and Canada covers both countries with the same data plan. As soon as you cross the border, your mobile automatically connects to the network of the country you are in, without you having to touch anything. It is the convenient option for road trips and combined trips.
The alternative is to buy a separate eSIM for each country. This makes sense if you are only going to one of the two: in that case, check our specific guide for eSIM for the United States. But if your itinerary includes both countries, the joint eSIM saves you from managing two different plans.
Consider a two-week trip along the East Coast: New York, Niagara Falls, and Toronto. With two eSIMs, you would have to activate the Canadian one just as you cross the border and manage two separate balances, usually in the worst place to look at your phone: at the Niagara Falls land customs, with a queue behind you. With a regional eSIM, the change is seamless, so your only worry is to enjoy the trip.
Operators and coverage in USA and Canada
Travel eSIMs rely on major local carriers. In the United States, these are T-Mobile and AT&T, with 4G and 5G coverage across virtually the entire country. In Canada, the networks are Rogers, Bell, and Telus, offering excellent coverage in the southern strip of the country, close to the US border, which is where the vast majority of the Canadian population lives.
In cities (New York, Los Angeles, Chicago, Toronto, Montreal, Vancouver), the signal is excellent, and you'll have 5G for video and video calls without interruptions. Outside major cities, things change quickly: in national parks and remote roads in the Rockies or the Nevada desert, there are long stretches without coverage, which is normal given the distance between populated areas. The same applies to sections of the Trans-Canada Highway between Calgary and Banff, where your phone might have no signal for minutes, even on a main road. Download offline maps for these areas before you leave, not when you're already lost looking for a detour.
How many GB to take for North America
For a typical city trip with maps, messaging, social media, and some video, estimate between 1 and 2 GB per week per person. If you're on a road trip, relying heavily on GPS and sharing your connection in the car, significantly increase that estimate.
| Trip Duration | Tourist Use (city, hotel wifi) | Road Trip with GPS and streaming |
|---|---|---|
| 1 week | 2-3 GB | 5 GB |
| 2 weeks | 5 GB | 10 GB |
| 1 month | 10 GB | 20 GB |
A note for road trips: GPS uses little data if you've downloaded offline maps beforehand, but streaming music and podcasts for hours of driving on straight highways in Wyoming or the Trans-Canada does add up, and after an hour of radio silence, it makes a difference. Download some music for long stretches between states or provinces, especially if you're going through areas where signal might be lost.
Another factor to consider is how many people are traveling. If two or three people are traveling and only one has the eSIM, sharing the hotspot for navigation and car music, that phone will consume data for everyone, and the plan will run out sooner than expected. In that case, either increase the GB of the initial plan, or each person carries their own eSIM to avoid relying on a single phone for the entire group's data usage.
Roaming to the USA and Canada: the surprise bill
Neither the United States nor Canada are in the European roaming zone, so your Spanish rate does not include free data there. Browsing with your home operator activates international roaming rates, which usually skyrocket far above what you pay in Spain; many travelers are shocked when they see the bill upon return, not during the trip but when they are already home and can't do anything about it.
Always check the current roaming price outside the EU with your operator before leaving: it changes frequently and varies greatly depending on the company and the contracted plan. With an eSIM, you pay a fixed rate before traveling and forget about the meter while you are away. If you want to see it in more detail, compare it in our guide on eSIM versus roaming.
Typical routes that cross the border
The joint eSIM shines on itineraries that blend the two countries. These are some classics where a single eSIM avoids juggling cards when crossing the border:
- East Coast: New York, Niagara Falls, and Toronto or Montreal.
- West Coast: Seattle and Vancouver, with a jump to the Canadian Rockies.
- Grand Route: Los Angeles and San Francisco before or after a stretch through Canada.
In all of them, you cross the border and your mobile automatically switches networks, without losing connection or having to reinstall anything. For the purely Canadian stretch of any of these routes, you have all the coverage and operator information in the eSIM for Canada guide.
What almost no one tells you
There are several details about the USA-Canada joint eSIM that are not listed in the product specifications and are worth knowing before purchasing:
- Network switching when crossing the border is not always instantaneous. It can take one or two minutes to connect to the new country's network, especially if you cross by road in an area with poor coverage on both sides (typical in rural border crossings, less so on major bridges like Niagara or Detroit-Windsor). If you need a connection right after crossing, be patient before thinking something has gone wrong.
- Airplane mode on landing, not before. A common mistake is to disable roaming for the Spanish line too early, in mid-flight, and lose the option to receive verification SMS (e.g., bank 2FA) until landing. Disable it on the ground, calmly, after activating the eSIM.
- Shared hotspot is not always activated by default. If you plan to share data with the rest of the group in the car, check in settings that the personal hotspot is enabled specifically for the eSIM line, not just for your physical line.
- Coverage inside skyscrapers and in New York or Toronto subway basements can be worse than on the street, just as it would be with any local operator. This is not an eSIM problem: it's the building structure blocking the signal.
- Save the eKit or confirmation email with the QR code even if you have already installed it. If you change phones mid-trip or need to reinstall, you will need it again.
How to activate your eSIM step-by-step
Ideally, you should install the eSIM with Wi-Fi at home, before leaving, and activate data only upon landing. This way, you arrive connected without relying on airport Wi-Fi or struggling with settings at the terminal.
- Purchase the USA and Canada eSIM and receive the QR code by email instantly.
- With Wi-Fi at home, go to Settings > Mobile Data > Add eSIM and scan the QR.
- Label the eSIM ("USA-Canada") to distinguish it from your Spanish line and avoid confusion about which to use for what.
- Upon arrival, activate the eSIM's data and disable roaming on your Spanish line.
- Check the connection by opening any website; if something doesn't work, review the installation guide before adjusting more settings.
If you've never used this technology, the step-by-step guide on how to install an eSIM will answer your questions in a couple of minutes, and if you're used to using physical chips on other trips, you might also be interested in international chip versus eSIM to understand the difference before deciding.
When a joint eSIM is NOT for you
Be honest with yourself about your itinerary before purchasing. If your trip is exclusively to one country, without setting foot in the other, there's no point in paying for joint coverage you won't use: you'll be better off with a specific eSIM for the United States or Canada, as appropriate. It also won't pay off if you're spending most of your time in a single destination with only a day trip to the other country: in that case, check first if your single-country plan already includes some punctual border coverage before doubling your expense.
And if your stopover in the other country is only for a few hours, for example, a connecting flight in Toronto on the way to another destination without leaving the airport's international zone, you don't need to activate anything: the airport's Wi-Fi is usually enough for that time.
Frequently asked questions
Does one eSIM work for both the USA and Canada?
Yes. A regional North American eSIM covers both countries with the same plan. When you cross the border, your phone automatically switches to the network of the country you are in, without you having to install or activate anything new. It's the ideal option for combined trips.
Is there free roaming in the United States or Canada with my Spanish plan?
No. Both countries are outside the European roaming zone, so your plan does not include free data there. Your operator would charge you international roaming at a price much higher than in Spain; check the current rate before traveling or use a local eSIM with a fixed price.
How many GB do I need for two weeks in the USA and Canada?
For a two-week tourist trip between cities, relying on Wi-Fi at your accommodation, 5 GB is usually enough. If you're on a road trip with GPS and in-car streaming, estimate about 10 GB to be safe and avoid running out of data halfway through your route.
Does it work in US and Canadian national parks?
There's usually coverage in access areas and visitor centers, but in the interior of remote parks and sparsely populated roads in both countries, you might lose signal simply because there are no antennas nearby. Download offline maps for those areas before entering.
Do I need ESTA or eTA in addition to the eSIM?
Yes, these are completely different procedures. The eSIM is only for your internet connection and has nothing to do with entry into the country. Arrange your ESTA for the US and eTA for Canada separately in advance; you buy the eSIM online without any associated immigration paperwork.
What happens if I run out of data halfway through my trip?
You can top up or extend the plan from the same panel where you manage your eSIM, without having to reinstall the profile or scan a new QR. It's a good idea to check your remaining consumption halfway through your trip, especially if you're on a road trip and usage has been higher than expected.
Can I use the same eSIM on a second trip later?
It depends on the specific plan: some profiles are linked to the activation date and expire when the period runs out, so for a subsequent trip, it's common to activate a new plan. Check the plan's validity when purchasing if you plan to return to the area soon.
Conclusion
Traveling in the United States and Canada with a single eSIM is the most convenient option when your itinerary includes both countries: data in both, automatic network switching when crossing the border, and a fixed price without roaming surprises upon your return. If, on the other hand, your trip is limited to a single country, a specific eSIM for that destination is better. Here are tips to save data with the eSIM you choose, and once your itinerary is clear, install the eSIM before you fly and forget about connectivity throughout your trip.
