The numbers

Head to head

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 Mobimatter and 1 sampled click for OHAYU. 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.

1 GB 7 days · 1 country £2.56 £2.56 per GB Buy → £7.70 £7.70 per GB Buy → 67% cheaper
3 GB 15 days · 1 country £2.56 £0.85 per GB Buy → £3.66 £1.22 per GB Buy → 30% cheaper
10 GB 30 days · 1 country £5.86 £0.59 per GB Buy → £6.96 £0.70 per GB Buy → 16% cheaper
50 GB 30 days · 1 country £13.20 £0.26 per GB Buy → £35.06 £0.70 per GB Buy → 62% cheaper

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

Where they overlap

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.

30/30

Mobimatter is cheaper in 30 of the 30 markets listed here that both of them price. Across those markets the dearer of the two costs 4.3 times as much per gigabyte on average.

Showing the 30 largest of the 175 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.

Pick Mobimatter if
  • Your destination is one of the 30 shared markets they are cheaper in
  • Price per gigabyte is what you are optimising for: £2.29 typical against £3.48
  • You want the cheapest gigabyte on the page: £0.01 against £0.54
  • You want the lowest entry price: their cheapest plan is £2.56 against £3.29
  • You need a validity window longer than 180 days
  • You are going to one of the 15 markets OHAYU does not reach
  • You would rather choose from a deep catalogue than a short one
Pick OHAYU if
  • You want 5G, advertised on 65% of their plans and on none of Mobimatter's
  • You are going to one of the 11 markets Mobimatter does not reach

Or neither of them

This page compares two providers because you asked for two. OHAYU is the 14 cheapest of the 23 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.
