Our verdict on each
Roamable
Roamable is a prepaid reseller selling eSIM data for travellers who want coverage in from 150 countries destinations without a contract. It suits people who buy data before a trip rather than anyone settling in a single market, and it scores 8.6 overall on the site.
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
Roamable
Pros
- Coverage reaches from 150 countries destinations on a single eSIM, and hotspot sharing is included.
- Billing is prepaid, and the listed Europe package runs with no contract, so there is nothing to serve out.
- Plans are sim only and eSIM only, so activation happens on the handset and no physical card is involved.
Cons
- Support runs on email and help centre, so help arrives by email or through the help centre rather than in a live chat.
- Entry price of €4.95 sits above the sim-only-deals median of €2.51, and the site places it 12 of 15 on price from.
- KnowRoaming lists an entry price of $1.75, below Roamable's €4.95.
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
Roamable
Who it suits
- Travellers crossing several countries on a single eSIM profile, rather than buyers who want a single local network: co:sim runs as an MVNO and ESIMZON names its partner networks directly.
- People who buy roaming before they buy a phone plan, and who are content with email and help centre as the help route.
- Short breaks where a single gigabyte of data and a short validity window are enough, since the listed Europe package runs on no contract.
Who should look elsewhere
- Anyone chasing the lowest entry price, because KnowRoaming lists $1.75 against Roamable's €4.95.
- People who need a specific named network at home or abroad: ESIMZON lists partner carriers including AT&T, Orange, Rogers, TIM, T-Mobile and Verizon, where Roamable works through an upstream partner.
- Buyers who want a network's own service: co:sim is an MVNO, while Roamable is a reseller whose help runs on email and help centre.
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
Roamable
What does a Roamable plan cost at the start?+
Roamable's entry pricing starts at €4.95, and the site places that figure 12 of 15 brands on price from. The listed Europe package works out to a single gigabyte of data with a short validity window, sold without a contract. So the cost weighed at entry is a small one-off top-up rather than a monthly commitment.
Is there a contract or a renewal term?+
Billing is prepaid, and the listed Europe package is sold with no contract, so there is no minimum term to serve out. Renewal pricing, which decides so many mobile bills, plays no part here: you buy a fixed data allowance with a validity window, and when it runs down you buy a fresh package rather than committing to another term.
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.
