MicroEsim

The figure that makes MicroEsim special isn't up for debate: its unlimited plans start at $0.21/day — the lowest per-day price across all 24 providers we track. The runner-up costs nearly three times as much.

And it's no one-off: 5,527 of its 8,883 plans are unlimited, the most unlimited-heavy catalogue we have. Its catalogue-wide median of $1.31/GB is also the lowest of this batch (sector: $2.00).

At 8,883 plans it's the second-largest catalogue in our comparison, with 33 durations from 1 to 90 days and 5G declared on 6,566 plans.

Here's the other side, and it weighs. MicroEsim's public footprint is minimal: about 39 reviews on Trustpilot Canada (4.4 out of 5) and 14 on the international site (3.8). Around fifty opinions, total, for a nine-thousand-plan catalogue.

Worse: trust validators flatly contradict each other — one scores it 95 out of 100, another 14%. When external signals clash like that, the honest position is that there is NOT enough evidence for a verdict on reliability, good or bad.

Among the few reviews: praise for fast delivery and stable connections, and one serious complaint — a plan that never worked, with support that never answered. Small sample, in both directions.

MicroEsim covers 159 destinations — among the narrowest catalogues we track (the full set is 204). Popular destinations are there; unusual ones probably aren't. Check before counting on it.

Its feed also doesn't declare whether plans allow tethering. That column comes up empty in our tables, and as always: empty means "the provider hasn't said", not "forbidden". If you work from a laptop, resolve that question with their support before buying.

Our reading: for travellers who want to stop counting gigabytes and pay very little, the numbers are unbeatable. For those who need certainties — coverage, tethering, track record — it's still a bet.
