Our verdict on each
BreezeSim
BreezeSim suits travellers and expats who want prepaid eSIM data rather than a handset contract, with plans starting at €4.95 and coverage across 190 countries. The trade-off is data that does not roll over and support running on chat, email and help centre, from a company registered in the United Kingdom.
ESIMZON
ESIMZON suits travellers who want prepaid eSIM data on partner networks with nothing owed after the trip, and its strength sits at the unlimited end of the range. Unlimited plans start at $2.90, while support runs on email, chat and help centre rather than by phone.

Pros and cons
BreezeSim
Pros
- Sim only plans start at €4.95 on prepaid billing, with no handset in the bundle.
- Coverage spans 190 countries, and eSIM, 5G and hotspot sharing are all included.
- A multi line discount is available for extra lines on the same account.
Cons
- Data rollover is not offered, so unused data is lost when a period ends.
- Support runs on chat, email and help centre only, with no phone line listed for urgent problems.
- The Explorer pass is sold on 12 month terms paid upfront, which is heavy for a short trip.
ESIMZON
Pros
- Unlimited plans start at $2.90, the strongest figure in that column of our data.
- Entry plans start at $1, and the UK range is prepaid with no contract, so a plan can end with the trip.
- Coverage spans 130 countries, so one plan covers a multi-country trip.
Cons
- It works as a reseller, so the host network behind a plan is picked for you rather than chosen.
- Support runs on email, chat and help centre, with no phone line for problems that matter while a trip is already under way.
- Billing is prepaid, so the range holds no long monthly plan for anyone who wants one steady recurring bill.
Who each suits
BreezeSim
Who it suits
- Frequent travellers who need data in 190 countries rather than on one home network.
- People who want a sim only eSIM and nothing tied to a handset.
- Households running extra lines, since a multi line discount is available.
Who should look elsewhere
- Buyers chasing the lowest entry price, since co:sim lists $0.99 against BreezeSim's €4.95.
- Shoppers who prefer to buy through a reseller, since ESIMZON and KnowRoaming list reseller and reseller where BreezeSim lists mvno.
ESIMZON
Who it suits
- Travellers who install an eSIM before departure and want a plan that ends with the trip: entry plans start at $1 with no contract.
- People crossing several borders on one plan, since coverage spans 130 countries across partner networks.
- Readers who already own a handset and want data only, because the range is sim only and esim.
Who should look elsewhere
- Readers who want an MVNO rather than a reseller, such as co-sim, since ESIMZON works as a reseller.
- KnowRoaming, which lists entry at $1.75, if you would rather weigh a different price list, or BambooSIM, an mvno, if that model matters more to you.
- Anyone who needs a phone line, because support runs on email, chat and help centre and reaches you in writing only.

Questions about each
BreezeSim
How much does BreezeSim cost when I start a plan?+
Plans start at €4.95 on prepaid billing, and the cheapest option overall is a Europe eSIM bought as a monthly prepaid plan with 5G where available. There is no separate introductory and renewal split to weigh here: you pay for the plan you choose, while the Explorer pass is sold on 12 month terms and paid upfront.
Do unused data roll into the next period?+
No, data rollover is not offered, so anything left at the end of a period is lost rather than carried into the next one. That matters most on a longer pass such as the Explorer pass sold on 12 month terms, where a quiet month leaves you with less than you paid for. Size the pass to your heaviest travel period and treat the rest as gone.
ESIMZON
What is the cheapest way to get data in the UK from ESIMZON?+
Entry plans start at $1 and are prepaid with no contract, so nothing carries into the next period. The capped-data UK eSIM plan is the lighter option, while the UK unlimited eSIM plans suit heavier use. On our price data, entry sits at 2 of 15 brands.
How much do the unlimited plans cost?+
Unlimited plans start at $2.90, and ESIMZON ranks 1 of 7 brands on that figure. The UK eSIM page lists those unlimited plans alongside a capped-data plan, all prepaid with no contract. Longer monthly plans are not listed, so a heavy monthly user has fewer options here.
