eSIM vs SIM vs Pocket Wi-Fi vs Roaming: Which Is Best? (2026)

For most Canadians on a trip of a week or more, a prepaid travel eSIM is the best balance of cost and convenience: you set it up at home, keep your Canadian number on the same phone, and pay once instead of every day. But it is not the best choice for everyone. Pocket Wi-Fi can suit a big group that stays together, a local SIM can win on long stays that need a local number, and carrier roaming is still the simplest way to take calls on your own number.

This guide compares all four options side by side, using October 2026 roaming rates from Bell, Rogers and Telus. We sell eSIMs, so we have tried to be fair: where another option is genuinely better for a type of trip, we say so.

The four ways to get mobile data abroad

Before comparing them, it helps to be clear about what each option actually is.

Travel eSIM. A data plan you download to your phone as a digital profile, usually by scanning a QR code. It runs alongside your Canadian SIM, so your phone has two lines: one for data abroad, one for your usual number. Our explainer on how an eSIM works covers the technology.

Local SIM card. A physical SIM from a mobile operator in the country you are visiting, bought at the airport, an operator shop or a convenience store. It replaces your Canadian SIM in the tray (or sits in a second slot), and it comes with a local phone number.

Pocket Wi-Fi. A small battery-powered router, rented or bought, that connects to a local mobile network and creates a Wi-Fi hotspot. Phones, tablets and laptops connect to it like any other Wi-Fi network.

Carrier roaming. Your Canadian plan working abroad on a partner network. Bell, Rogers and Telus charge a daily fee on each day you use your phone outside Canada, and you keep your number, calls, texts and data as at home.

The rest of this guide explains each row and who each option suits best.

How much does each option cost?

The four options charge in completely different ways, which is why they are hard to compare at a glance.

Carrier roaming: Bell, Rogers and Telus daily rates

As of October 2026, Bell’s travel page lists Roam Better at $13 a day in the US and $16 a day in international destinations, with a maximum of 20 charged days per line per billing period. Rogers says on its roaming billing page that you pay $16 for a day of roaming in the US and $18 in a destination such as Germany. Telus Easy Roam is $16 a day in the US and $18 internationally.

Rogers also sells Travel Passes that work out cheaper per day on longer trips: US passes of 3, 7, 14 and 30 days cost $25, $50, $60 and $80, and international passes for 180+ destinations cost $45, $75, $100 and $120.

Trip	Bell	Rogers (daily)	Rogers Travel Pass	Telus
US, 7 days	$91	$112	$50	$112
US, 14 days	$182	$224	$60	$224
International, 7 days	$112	$126	$75	$126
International, 14 days	$224	$252	$100	$252

These figures are per phone, so a family of four on daily roaming pays four times over. Our Bell, Rogers and Telus roaming comparison goes deeper into what each plan includes.

Travel eSIM

A travel eSIM is a one-off prepaid purchase. Plan lengths and data sizes vary by destination: our Global plans come in 7, 30, 90 and 365-day versions, Europe plans run from 7 to 180 days, and data sizes go from 1 GB up to 100 GB on some destinations. There is no daily fee and nothing to cancel. Here are live prices for our Europe plans:

Local SIM and pocket Wi-Fi

Local SIM prices are set by each country’s operators and change often, so check the operator’s own website for the country you are visiting rather than relying on a figure in a blog post. Pocket Wi-Fi costs depend on the rental company, the rental length and the data allowance. With both, factor in what is not on the price tag: time spent finding a shop on arrival, delivery or return logistics, and any deposit or loss terms.

When carrier roaming is the best choice

Roaming has a reputation for being expensive, and at $13 to $18 a day it usually is. But it wins in a few clear situations.

• Very short trips. For a day trip across the border or a two-day work visit, a few days of roaming may cost about the same as a plan, with no setup at all.
• You need full calling on your number. Roaming is the only option here that lets you make and receive regular calls and texts on your Canadian number exactly as at home. If clients, a care home or your kids’ school must be able to reach you, that matters.
• You travel to the US often on Rogers. A Rogers US Travel Pass at $60 for 14 days is competitive with a travel eSIM for a frequent cross-border traveller.
• Your phone cannot take an eSIM. If the phone is locked or has no eSIM chip, roaming may be the easiest fallback.

If you mostly need calls, look into Wi-Fi calling as well. Apple’s guide to Wi-Fi Calling shows how to turn it on, and your carrier can tell you how calls placed from abroad are billed.

When a local SIM card is the best choice

A local SIM is the most traditional option, and for some trips it is still the right one.

• Long stays. If you are studying, working or living somewhere for several months, a local prepaid or monthly plan from a local operator can be the cheapest way to get large amounts of data. Our guide for students and long stays abroad covers this in detail.
• You need a local phone number. Landlords, local banks, delivery apps and restaurants may want a number in that country. A data-only travel eSIM, including ours, does not include one.
• Top-ups in person. Some travellers like being able to walk into an operator shop and get help in person.

The trade-offs are real, though. Your phone must be unlocked and have a SIM tray, and some phones no longer have one: Apple’s eSIM setup page notes that some iPhone models are eSIM-only. You also need to find a shop after a long flight, and removing your Canadian SIM means you stop receiving texts to your usual number, including bank verification codes, unless your phone supports dual SIM.

When pocket Wi-Fi is the best choice

Pocket Wi-Fi gets less attention than it deserves for one type of trip: a group that travels as a unit.

• Big groups sharing one connection. A family or group of friends who spend the whole day together can connect phones, tablets and a laptop to one device, with nobody’s phone acting as the hotspot.
• Lots of non-phone devices. Tablets without cellular, laptops and handheld game consoles all connect over Wi-Fi.
• Phones that cannot use an eSIM. Older or locked phones can still connect to a pocket Wi-Fi.

The downsides show up as soon as the group splits. Whoever is not carrying the device has no data. It is also another battery to charge every night, another item to lose, and, if rented, something you must return on time. A phone hotspot from one travel eSIM does much of the same job without the extra device; our guide to sharing mobile data with family abroad compares the two.

When a travel eSIM is the best choice

An eSIM is our product, so take this section with that in mind. It tends to win when:

• The trip is a week or longer. A one-off prepaid plan usually costs less than seven or more days of daily roaming.
• You want to keep your Canadian number. On a Dual SIM phone your Canadian line stays on for calls and texts while the eSIM carries data. Our guide to keeping your Canadian number with Dual SIM shows the settings. Apple’s Dual SIM guide explains how iPhone handles two lines.
• You want to be connected on landing. You install the eSIM at home, and with ArriGo the plan’s days only start when it first connects at your destination. Our guide to installing an eSIM before you fly walks through it.
• Each person moves independently. Couples and families who split up during the day can each have their own eSIM. One order can include up to 10 eSIMs, each installed on one phone.

An eSIM is not ideal if your phone is not compatible (check with our compatibility checker), if you need a local phone number, or if you need regular calls on your Canadian number and do not want to rely on calling apps.

Pick by traveller type

Traveller	Our honest pick	Why
Weekend in the US	Roaming or an eSIM	For two or three days the cost gap is small; an eSIM pulls ahead after that
Couple, two weeks in Europe	One eSIM each	Each phone has data, Canadian numbers stay on for texts
Family of four, one week all-inclusive	One eSIM plus hotspot, or one each	Parents’ phones carry data, kids connect by hotspot or resort Wi-Fi
Group of six touring together	Pocket Wi-Fi or one eSIM each	One device works if the group never splits up
Student, a semester abroad	Local SIM, possibly with an eSIM for the first weeks	A local number and long-stay rates matter
Business traveller	eSIM plus roaming on calling days	Data on the eSIM, Canadian number reachable when needed
Cruise passenger	Depends on the itinerary	Ship networks work differently; see our cruise roaming guide

Can you combine them?

Yes, and many experienced travellers do. The most common combination is a travel eSIM for data with the Canadian line kept on for incoming texts, data roaming off. Another is one eSIM per adult with a hotspot for children’s tablets. On a long stay, you might use an eSIM for the first week while you sort out a local SIM.

The one combination to avoid is leaving data roaming on for your Canadian line while also using an eSIM, since your carrier may start its daily fee. If something does not connect after landing, our guide to fixing an eSIM that is not working abroad covers the usual settings.

Your next step

Start by checking whether your phone can take an eSIM with our compatibility checker. If it can, compare plans for your trip, whether that is the United States, Europe or a Global plan for several countries, or browse all destinations. If a local SIM, pocket Wi-Fi or roaming suits your trip better, that is a fine choice too, and our help centre can answer questions either way.
