The Best eSIM for Canadian Business Travellers in 2026 and 2027

A two-week business trip to Europe on a Rogers, Bell, or Telus plan costs $252 per person in roaming fees before a single euro is spent on hotels, meals, or taxis. A trip to New York for a week costs $112. Add a second person from the same company and those numbers double.

This is the default outcome for Canadian business travellers who do not prepare. The bill arrives weeks after the trip -- long after the expense report is filed and the meetings are forgotten.

A travel eSIM eliminates this entirely. Here is what corporate travellers, travel managers, and concierge services need to know.

What Carrier Roaming Actually Costs on a Business Trip

Rogers, Bell, and Telus charge $16/day for US roaming and $18/day for all international destinations. The daily fee fires on any outgoing activity -- sending an email, opening Slack, joining a video call, or checking a flight status on landing. There is no way to use your phone for work and avoid the charge.

For a team of three travelling together on a 10-day international trip, the combined roaming bill is $540 -- before any of them have opened a single work email.

Under the CRTC's Wireless Code, carriers cannot charge more than $100 per line per billing cycle without explicit consent. In practice, business travellers almost always agree to continue when asked -- because the alternative is going dark in the middle of a deal.

What a Travel eSIM Is and How It Works

An eSIM is a digital SIM card embedded in your phone. Instead of a physical SIM from a carrier, you download a plan from a provider like Cellulo directly to your device -- no store visit, no SIM swap, no waiting. The entire setup takes under two minutes on Wi-Fi.

For business travellers, the advantages are direct:

No contracts. Every Cellulo travel eSIM is a one-time purchase for the duration of your trip. No monthly commitment, no cancellation fee, no ongoing relationship with a foreign carrier.

Instant setup. Purchase and install the eSIM before your departure -- ideally within two weeks of travel. It activates automatically when your phone connects to a covered network on landing.

Global coverage. Cellulo sells travel eSIMs for 200+ countries and territories. Whether the trip is New York, London, Tokyo, Dubai, or Sao Paulo, there is a plan available.

5G speeds where available. Plans connect to local networks including 5G in major business destinations -- T-Mobile and Verizon in the US, leading operators across Europe and Asia.

The Canadian Number Problem -- and the Solution

The most common concern from business travellers: clients, colleagues, and head office call the Canadian number. Turning the line off means missing calls.

The solution is straightforward and takes 30 seconds to set up before any international trip.

Turn off Data Roaming on your Canadian line first, then turn the line off completely in Settings -> Cellular. With the line off, your phone does not register on any foreign network -- no roaming charges, no accidental $16 days.

For calls and messages, WhatsApp, FaceTime Audio, and iMessage all work normally over the eSIM data connection. Anyone who calls your Canadian number can be directed to WhatsApp or a forwarding number for the duration of the trip. Most business travellers find that colleagues and clients adapt quickly -- particularly when it is explained that calls over WhatsApp or FaceTime Audio are free on both ends.

For OTP codes, two-factor authentication, and verification texts to the Canadian number: turn the Canadian line back on briefly, receive the text, then turn it off immediately. As long as no outgoing calls or texts are made while the line is on and roaming, the daily fee does not trigger. The process takes 30 seconds.

Do not use Airplane Mode as a substitute for turning the line off -- Airplane Mode disables the eSIM as well.

What to Look for When Choosing a Business Travel eSIM

Not all travel eSIMs are equal. For business travellers specifically, four things matter:

Network quality at the destination. A cheap eSIM that runs on a secondary network is not worth the saving if it drops during a video call. Cellulo plans connect to leading operators at each destination -- T-Mobile and Verizon in the US, major tier-one operators across Europe and Asia.

Data sufficiency for business use. Business travel is data-intensive -- video calls, large file transfers, cloud-based tools, and corporate VPNs all consume more data than leisure browsing. Unlimited plans are worth the premium for trips longer than five days. For shorter trips or light users, a 5-10GB plan typically covers a week of moderate business use.

Multi-country coverage for complex itineraries. A regional plan covering Europe or North America is more practical than buying individual country eSIMs for trips that span multiple destinations. Cellulo offers regional plans covering Europe, EU + UK, North America, and other multi-country zones -- one eSIM, one purchase, one activation.

Simple setup. Business travellers do not have time to troubleshoot connectivity at the airport. Cellulo's eSIM installation is guided, takes under two minutes, and can be completed on Wi-Fi at home before departure.

For Travel Managers and Concierge Services

Managing connectivity for a team of travelling employees is one of the most overlooked sources of preventable expense in corporate travel budgets. A team of five travelling internationally for 10 days each quarter generates over $3,600 per year in carrier roaming charges -- before accounting for anyone who exceeds the CRTC's $100/line cap and agrees to continue.

Cellulo's travel eSIM platform is available to individual travellers and can be used by travel managers and concierge services to source plans for clients before departure. Each plan is purchased independently, installed on the traveller's device, and active from the moment they land -- no carrier negotiation, no corporate account required, no roaming claims to process after the trip.

For high-frequency travellers, the habit of installing a Cellulo eSIM before every international departure replaces the habit of calling the carrier to add a roaming package -- and costs significantly less.

Cellulo Is Listed on the CRTC's Official Comparison Directory

Cellulo is listed on the Canadian Radio-television and Telecommunications Commission's official comparison site directory at crtc.gc.ca/eng/comm/compar.htm -- the government-backed list of trusted comparison platforms the CRTC directs Canadians to when comparing wireless services. For travel managers and corporate procurement teams that require vendor due diligence, this listing is an independent signal of Cellulo's legitimacy as a Canadian wireless platform.
