Best eSIM for Montreal in 2026
— Ranked by Real Performance

Airalo is the strongest choice for Montréal, accessing Bell Canada's wholesale network with QoS-prioritised data that holds up during high-traffic periods — something budget competitors struggle with. Their Canada plans offer up to 10 GB at competitive pricing, and activation is typically live within minutes via the Airalo app, which matters if you're landing at YUL and need connectivity before clearing customs.

Yes — all four STM metro lines (Orange, Green, Blue, Yellow) have in-tunnel cellular coverage via a shared Bell/Rogers DAS infrastructure, a rollout completed in stages between 2019 and 2022. Speeds in tunnels typically run 20–40 Mbps, sufficient for maps and messaging; platform areas at major interchange stations like Berri-UQAM and Lionel-Groulx generally achieve closer to 50–80 Mbps. Above-ground STM bus routes are covered by standard outdoor macro-cell networks with no meaningful gaps on island routes.

For a week of typical visitor use — Google Maps navigation across the Plateau and Old Port, light Instagram posting, occasional streaming on evenings in — budget 8–12 GB. Navigation burns roughly 150–200 MB/day, social media another 300–500 MB/day, and a couple of hours of streaming adds 1–2 GB. A 10 GB Airalo Canada plan covers most travellers with a small buffer; step up to 15–20 GB if you plan to tether a laptop or attend events where venue Wi-Fi is unreliable.

Airalo, Nomad, and 4S eSIM all explicitly permit hotspot/tethering on their Canada plans — Nomad in particular markets this as a feature for remote workers. Holafly restricts hotspot use on its unlimited Canada plan, which is a significant limitation if you need to connect a laptop. Amigo's tethering policy is plan-dependent and worth confirming at purchase. Always check the 'fair use' data cap on tethering: Nomad applies a soft deprioritisation above 10 GB of hotspot use in a single billing cycle on Canadian wholesale capacity.
