01 / What to buy

Their best plans right now

Their own plans, ranked on price per gigabyte rather than on headline price. Two that cover more than one country and two that cover a single market, so you can see how differently the same provider prices breadth.

02 / The catalogue

What JamboSim publishes

Read from their live catalogue on a schedule. Percentages are shares of their plan-market coverage, and a blank figure means they do not publish it.

8% Advertise 5G Their claim about the host network, not a guarantee of signal

100% Permit hotspot Where a provider does not say, we record it as unspecified

100% Can be topped up Run out without it and you buy a whole new plan

1 620 Forfaits illimités Excluded from every median, because a threshold is not an allowance

365 Longest validity, days The longest window they sell

2 138 distinct plans reach 203 markets, which is 9 701 plan-market combinations. A multi-country bundle counts as one plan here, not one per country it covers.

03 / Against the field

Typical price per gigabyte across each provider's whole catalogue. Lower is better, and this is the figure marketing never leads with.

We keep every price we read: 2 138 observations of this provider's plans so far, over 6 days. That is not yet long enough to call a trend, so we do not publish one. A price movement needs at least 14 days of history behind it before it means anything, and this section fills itself in once the window is wide enough.

04 / Our code

15% off at JamboSim

A code appears here only once a person has checked it and recorded the date. Where one exists it applies at the provider's own checkout, on top of every price on this page.

05 / Coverage

Where they are worth buying

The 40 cheapest of the 203 markets they reach. A provider can be excellent value in one country and poor in the next, because coverage is not a quality.

06 / Buying and support

What the purchase is actually like

Price is half a review. This is the other half, taken from what their catalogue publishes rather than from their marketing. A share of nothing means they do not publish it.

Activation trigger Not published on any plan When the clock starts — at purchase, on install, or on first connection

Recharge possible On every plan they sell Whether you can extend a plan instead of buying another

ID check required Not published on any plan Some markets require identity documents before activation

Reusable eSIM Not published on any plan Whether the same profile can be topped up and used again later

Local IP address Not published on any plan Traffic breaking out locally rather than in the home country

Phone number included Not published on any plan Most travel eSIMs are data only

07 / Accuracy

Does their listed price survive to checkout?

We measure this ourselves rather than taking their word for it.

Prices that still matched

Measured from our own outbound clicks, not from anything they told us.
Nobody has clicked through to this provider often enough for us to have measured it. We publish the figure when there is one, not a default.

A score below 100% is not automatically dishonesty. Currency conversion, regional pricing and stale caches all cause it. It does mean you should read the total before paying.

Links to this provider may earn us a commission at no extra cost to you. It has no bearing on their position in any ranking, and no payout figure is available to the code that ranks plans.

08 / Readers

What readers report

First-party ratings only. Nothing here is taken from anywhere else, and an aggregate score appears only once a provider has five.

Nobody has rated this provider yet. Yours would be the first.

A person reads every review before it appears. We do not publish an aggregate score until at least five have been approved, and we never edit a review to soften it.

Useful reviews mention where you used it whether it connected on landing signal outside the city
