The numbers
Face à face
Green marks the better figure on each row. Where they match, neither is marked. Nothing here is weighted or scored: these are the published figures side by side.
ZenSIM
Average per GB is computed only over plans where a per-gigabyte figure is derivable, so a catalogue full of unlimited plans is not flattered by counting zeroes. Price accuracy is measured from our own outbound clicks rather than taken from either provider: 1 sampled click for Bloomey eSIM and 0 sampled clicks for ZenSIM. A perfect score from a hundred clicks is a weaker claim than one from four hundred, so the counts travel with it, and a provider nobody has clicked through yet has no score at all rather than a flattering default.
Same size, both providers
What each actually charges
Aggregates tell you about a catalogue. These are real plans at matching allowances, the same validity window and the same breadth of coverage, which is what you would actually be choosing between.
Each row pairs plans with the same allowance, the same validity window and the same number of countries, so neither side is penalised for covering more. The Buy links go to each provider's cheapest live plan rather than to the plan on that row: we only link to a plan we can track, and their own checkout is always authoritative.
Like for like
Où ils se recoupent
The comparison that means something: the same market, both providers, cheapest gigabyte each. An average across different countries is not a like-for-like number.
ZenSIM is cheaper in 17 of the 22 markets listed here that both of them price. Across those markets the dearer of the two costs 1,9 times as much per gigabyte on average.
Not in this sample. They share 125 markets and this table lists 30 of them, so your destination is very likely covered by both. Its country page carries every provider selling there, not only these two.
Showing the 30 largest of the 125 markets they share. Each row is the cheapest honest gigabyte each provider sells in that country; where either publishes no per-gigabyte figure the row shows no gap rather than a winner.
Which to pick
When each one is the right buy
Every reason below is drawn from a figure in the table above, so none of them outlives the fact behind it.
- Your destination is one of the 5 shared markets they are cheaper in
- You want the lowest entry price: their cheapest plan is €0.43 against €3.43
- You would consider an unlimited plan, which ZenSIM does not sell at all
- You want 5G, advertised on 59% of their plans and on none of ZenSIM's
- You need a validity window longer than 90 days
Pick ZenSIM if
- Your destination is one of the 17 shared markets they are cheaper in
- Price per gigabyte is what you are optimising for: €3.76 typical against €4.59
- You want the cheapest gigabyte on the page: €0.40 against €0.53
- You need to tether, allowed on 100% of their plans and on none of Bloomey eSIM\x27s
- Topping up matters, because none of Bloomey eSIM's plans support it
- You are going to one of the 115 markets Bloomey eSIM does not reach
Or neither of them
This page compares two providers because you asked for two. ZenSIM is the 9 cheapest of the 22 catalogues we read, and on plenty of trips the right answer is a third provider entirely. The destination page for wherever you are going ranks every provider selling there on the same figures used above.
We earn a commission on some outbound links. Which provider comes out ahead on any row above is computed from their published prices, not from what either pays us, and no payout figure is available to the code that ranks plans.
