JamboSim

JamboSim publishes 1,836 plans across 190 destinations, and all 1,836 are single-country. Like Nomad, there isn't one regional or global plan.

For a single-country trip that's usually an advantage: local plans cost less per gigabyte than worldwide bundles, which spread their price across dozens of destinations.

$0.349/GB at travel sizes, mid-sector. Entry price $1.99, among the lowest, and they sell from 500 MB.

731 of its plans are unlimited, from $0.60 a day. That puts it among the three cheapest we track for people who'd rather not count gigabytes, alongside Roamix and mySIM24.

The catch: they don't declare the daily allowance on any of those plans. Not one of the 731. So we can't tell you how many gigabytes run at full speed before throttling, and that column comes up empty in our tables.

Absence isn't the same as absence of a limit. Nearly every unlimited plan in this sector has a cap; if theirs matters for your trip, ask before buying.

All 1,836 plans declare 5G, consistent with a modern catalogue. They don't publish whether tethering is allowed, so that column stays empty.

It's a provider with very little presence in traveller comparisons and forums, so there's little third-party experience to cross-check against. That doesn't make it worse, but it does mean that if something goes wrong on arrival, you'll find fewer people who've hit the same thing.

Its largest size is 50 GB, more contained than others. Plenty for a normal trip; short for a long stay sharing a connection.
