Best travel eSIM United States: Cellulo plans that beat $16/day roaming
Updated June 11, 2026 · Cellulo Team
Land in the US without a plan and Rogers, Bell, or Telus can start charging $16 per day. A one-week trip turns into $112 for one person, or $224 for two, which is why the best travel eSIM United States option usually pays for itself before the trip is over.
Cellulo's USA eSIM plans cost from $6 CAD to $98 CAD, activate automatically on arrival in United States, and let you stay connected in United States without the usual roaming bill waiting at home. Even the 7-day unlimited plan at $38 costs less than three days of carrier roaming. If you just need light data for maps, messages, and booking confirmations, the 7-day 1GB plan is $6.
Best travel eSIM United States plans compared
All of these are data-only eSIMs. They do not include calls or SMS, so WhatsApp, FaceTime, iMessage, Google Meet, Slack, and other data-based apps matter more than your regular phone number while you travel.

How much cheaper is a USA eSIM than roaming?
The math is not close. Carrier roaming to the US is $16/day.
- 3 days of roaming: $48 vs $16 for Cellulo unlimited 3 days
- 7 days of roaming: $112 vs $38 for Cellulo unlimited 7 days
- 10 days of roaming: $160 vs $48 for Cellulo unlimited 10 days
- 15 days of roaming: $240 vs $67 for Cellulo unlimited 15 days
- 30 days of roaming: $480 vs $96 for Cellulo unlimited 30 days
For a couple taking a week-long trip, roaming can hit $224. Two 7-day unlimited eSIMs cost $76 total. That is a $148 difference, and you still get data as soon as you land.
That matters in the first hour of a US trip. If you are landing in New York, Miami, Los Angeles, or Las Vegas, you probably need Google Maps right away, a rideshare app to leave the airport, and access to hotel emails or check-in details. Airport Wi-Fi is often slow or overloaded, and hunting for a SIM kiosk after a flight is a waste of time when your phone could already be working.
For lighter trips, the smaller plans make sense. A 7-day 1GB plan at $6 or a 15-day 2GB plan at $10 works if you mostly use Wi-Fi and just want backup data for maps, restaurant searches, boarding passes, and messaging. If you plan to upload stories, work remotely, join video calls, or stream on the go, the unlimited options are the safer bet.
How to use a United States eSIM without triggering roaming
Install the eSIM before you leave Canada. You need Wi-Fi for setup, so do it at home or before heading to the airport, not after you land.
The key step is turning your Canadian line off completely in your phone's cellular settings before landing in the US. Do not just switch off data roaming. If your Canadian line stays active, your carrier can still register on a US network and trigger roaming charges.
Use the USA eSIM for all data during the trip. If you need a one-time password or 2FA code sent to your Canadian number, turn your Canadian line on briefly, receive the code, then turn it off again.
Do not use Airplane Mode as your workaround. Airplane Mode disables the eSIM too, which defeats the point. Turn off the Canadian line specifically and leave the travel eSIM active.
Who should pick which USA eSIM plan
The 7-day unlimited plan at $38 is the easiest recommendation for most travellers. It covers the most common trip length, costs less than three days of roaming, and removes the stress of watching your data use while navigating, calling rides, or sharing photos.
The 5-day unlimited plan at $26 is strong for quick work trips where you need reliable data for email, Slack, and hotspot backup. The 10-day and 15-day unlimited plans fit longer vacations and road trips where you will lean on maps, restaurant apps, translation tools, and travel bookings every day.
The 30-day capped plans are where value gets interesting. If you are staying longer and have dependable Wi-Fi at a hotel, condo, or family home, $19 for 5GB or $32 for 10GB is far cheaper than paying daily roaming fees. The 40-day unlimited plan at $98 is the closest thing here to a set-it-and-forget-it option for snowbirds and extended stays.
Coverage depends on the local networks the eSIM connects to in the United States. In major cities and travel corridors, that is usually the part most travellers care about. If your trip includes remote parks or rural stretches, expect coverage to be less consistent than in urban areas.
If you want the best travel eSIM United States option for your trip length and data use, start with the USA plans on Cellulo and pick the one that beats your carrier's roaming math.
