Our verdict on each
eSIMania
eSIMania suits travellers and eSIM users who want prepaid Europe data, EU roaming included, and a contract that ends quickly. Entry price of $9 sits in the middle of the field, and the reference plan prices cover both Europe and Global packages.
USIMS
USIMS suits travellers who want prepaid data while away, with entry at $2 and roaming across 120 countries. The catch is what that entry buys: the published list holds no monthly, contract or unlimited tier, so a trip means buying a fresh package rather than renewing a set plan.

Pros and cons
eSIMania
Pros
- eSIM and sim only across the range, which suits anyone travelling light with an eSIM handset.
- Billing is prepaid and the contract length is 1 month, so a package can end when a trip does.
- EU roaming is included on the Europe packages, and coverage spans 41 to 200 countries.
Cons
- Data rollover is a no, so an allowance left at the end of a package does not move into the next one.
- The price rise rule leaves pricing with the third party provider behind a data package, who may change the price, capacity or duration at any time, so a sized package carries risk across its life.
- Entry price of $9 sits above $1 at ESIMZON and $1.75 at KnowRoaming, so the floor on this market is elsewhere.
USIMS
Pros
- Roaming covers 120 countries, so a package list can carry a trip across several borders without swapping providers.
- Sim only is available and eSIM is supported, so a new phone can be online without waiting for a card in the post.
- Billing is prepaid, so there is no contract term to serve and nothing to close when a trip ends.
Cons
- A monthly or unlimited plan is not among its reference plan prices, which are prepaid data packages by country, and prepaid billing means each top-up is a fresh purchase rather than a renewal.
- USIMS can revise charges and publish them in its app and on its site, so the entry price of $2 is not a figure you can plan a later top-up around.
- Support runs on email, chat and help centre only, with no phone line listed for problems that cannot wait.
Who each suits
eSIMania
Who it suits
- Travellers landing in Europe who want data that keeps working across the region, with EU roaming included.
- People on an eSIM handset who want a prepaid package lasting 1 month rather than a long commitment.
- Shoppers who read the reference plan prices first, since the range is quoted per package for Europe and Global use.
Who should look elsewhere
- Anyone chasing the lowest entry price: eSIMania's entry price of $9 sits above $1 at ESIMZON and $1.75 at KnowRoaming.
- Buyers who want a plan sold by a network-linked provider: co:sim is a mvno while eSIMania is a reseller.
USIMS
Who it suits
- People crossing several borders and paying for data a package at a time rather than through a monthly bill.
- Owners of a new phone who want data running straight away through an eSIM.
- Buyers who treat the number as a travel tool and top up again when a package runs out instead of tracking a renewal date.
Who should look elsewhere
- Shop-first buyers: ESIMZON and KnowRoaming are resellers, where USIMS is an mvno.
- Anyone after unlimited data: the site median of €12.27 for unlimited plans comes from sellers that list them, and USIMS does not.
- Travellers who need a rate held for the whole stay, since USIMS can revise charges and puts the new figures in its app and on its site.

Questions about each
eSIMania
How much does eSIMania cost to start?+
Entry price of $9. The reference plan prices are quoted per package rather than per month, covering a short Europe package, a longer Europe package and a Global package, so the figure that matters depends on how long you need data and where you land. Billing is prepaid across the range.
Can the price of a package change after I buy it?+
There is no fixed mid-contract cap stated. Under the price rise rule, the third party provider behind a data package may change the price, capacity or duration of that package at any time without notice. The term is short, which limits the exposure: billing is prepaid and the contract runs 1 month.
USIMS
How much does USIMS cost to start?+
Entry is $2 and billing is prepaid, so you pay for a package rather than a monthly bill. The published data plans are short validity bundles bought per country, and there is no monthly, contract or unlimited tier on the list, which makes the top-up the whole commitment.
Is there a contract or a renewal price to check?+
There is no contract term, and the plan list has no monthly, contract or unlimited tier, so nothing renews on a schedule. Billing is prepaid: when a package runs out you buy another one at the current charge, and the terms let USIMS revise charges and publish them in its app and on its site.
