JamboSim eSIM plans and prices
Every JamboSim plan we track, the price per gigabyte on each, and where this provider wins or loses against the other 89 in the index. Figures are read from their live catalogue, not their marketing page.
JamboSim at a glance
We do not publish a star rating for providers. We hold no verified buyer reviews to base one on, and an invented score would be worth less than the numbers above.

Every JamboSim plan we can price per gigabyte
Sorted by price per gigabyte. The struck-through figure is JamboSim's list price; the bold one is what you pay with the code applied at their checkout. Of its 2,109 plans, 1,291 carry a fixed allowance and a real term, so those are the ones a per-gigabyte figure can be computed for.
Where JamboSim wins, and where it doesn't
Every line below is derived from the catalogue, not written by hand. We hold no field speed test, so nothing here claims to be one.
✓Pick JamboSim when
- Wide coverage. 195 of the 239 countries in the index.
- The 15% code applies here. Every price on this page shows the discounted figure with the list price struck through.
- Unlimited plans are available. 818 of its 2,109 plans, each with the provider's own fair-use wording shown.
- Cheap to try. Entry price of $1.99, so testing it costs very little.
!Look elsewhere when
- Not the value play for heavy data. Its best rate is $0.35 per GB against $0.06 elsewhere on the site, about 6.2x.
- It is not the cheapest everywhere. On most country pages another provider wins, and those pages say so rather than favouring anyone.

JamboSim questions
Is JamboSim good value?
It depends what you need. Its cheapest plan is $1.99, and its best rate works out at $0.35 per gigabyte. The best rate anywhere in our index is $0.06 per gigabyte, so for data-heavy trips it is around 6.2x that.
How many countries does JamboSim cover?
195 in our index, out of 239 covered across all providers. Broad coverage is not the same as being cheapest in any of them.
Is there a JamboSim promo code?
We hold ESIMADVICE, worth 15% off. 15% discount. Enter it at their own checkout and confirm the total drops before paying.
Does JamboSim sell unlimited plans?
818 of its 2,109 plans are sold as unlimited, and nearly all such plans carry a fair-use cap in the small print. Each one shows the provider's own wording.
Can I use JamboSim as a hotspot?
Its plan descriptions mention hotspot or tethering on 2,109 plans. Where a plan does not say so, treat it as unconfirmed and check their page before buying.
Does JamboSim work with my phone?
If your handset supports eSIM, yes. Dial *#06# and look for an EID; no EID means no eSIM whatever the provider. Carrier-locked phones sometimes block it even when the hardware supports it.
Why is there no star rating on this page?
Because we hold no verified buyer reviews to build one from, and a made-up score would tell you nothing. The plan count, prices and coverage above are read from the live catalogue and are checkable.
