Our verdict on each
Simsima
Simsima suits travellers who want a prepaid eSIM covering Europe and a long list of other destinations, with entry prices from $1.50 and unlimited data sold as a weekly plan.

Pros and cons
Simsima
Pros
- A credit check is not required, so an eSIM profile can be set up without one.
- Simsima sells as an MVNO, so it sits with the network-side sellers in this group while ESIMZON and KnowRoaming are both resellers.
- Billing is prepaid, so a trip-only top-up is possible and nothing has to run to a contract end.
Cons
- Support runs on email and help centre only, so a problem that needs a voice on the line waits on an email reply.
- On unlimited price it ranks 7 of 7 brands, which is the measure where it has least to show against its rivals.
- The terms name an individual, Dimitri MORVAN BRAHIM, as the legal entity, so the counterparty is a person rather than a corporate provider.
Strong eSIM
Pros
- Entry at $3.50 buys a prepaid starter plan with no contract term, so a short trip costs little and ends cleanly.
- Coverage runs on local partner carriers across 197 countries, so one eSIM can carry a multi-country itinerary.
- Hotspot sharing and fifth generation data come with the same prepaid plans, so tethering and faster speeds need no add-on.
Cons
- Data rollover is listed as no, so an allowance left unused is gone when a prepaid plan runs out.
- Every plan is prepaid on a short validity, so there is no long contract over which to spread the cost of steady use.
- Support runs on email, chat and help centre, with no phone line listed for problems that need a voice.
Who each suits
Simsima
Who it suits
- Travellers crossing several European borders who want a prepaid eSIM they set up themselves.
- People who want European roaming included and a top-up rather than a contract.
- 5G users who also want hotspot sharing on the same profile.
Who should look elsewhere
- Anyone who wants to phone for help: support runs on email and help centre only, and KnowRoaming, a reseller, is the alternative to weigh.
- Buyers hoping for a discounted annual rate: billing is prepaid, so ESIMZON, a reseller, is the other name here.
- Anyone who needs a single named host network: co:sim describes its network as local carrier networks, the simpler proposition to weigh.
Strong eSIM
Who it suits
- Backpackers and short-break travellers who want a prepaid eSIM live in the destination, starting at $3.50.
- Anyone crossing several countries on one trip, with service on local partner carriers across 197 countries.
- People with eSIM-capable handsets who need data and hotspot sharing without signing up to a contract.
Who should look elsewhere
- Travellers who prefer a reseller's own package list can look at ESIMZON, a reseller, rather than an mvno catalogue.
- Long stays with heavy usage are better weighed against KnowRoaming, a reseller, before committing, since Global Unlimited bills $14.90 for each travel day.
- Shoppers who want help by phone, since support runs on email, chat and help centre only.

Questions about each
Simsima
What does a Simsima plan cost to start?+
Entry pricing begins at $1.50, and every plan is bought as a prepaid top-up rather than a contract. That means the starting figure is the figure you pay, and the same amount applies when you refill, so there is no introductory rate that later renews higher. The unlimited plan is priced separately at $22.12.
Does signing up need a credit check?+
A credit check is not required, and the plans are sim only, so nothing is financed and no handset sits on the plan. The eSIM profile is created without a credit file being consulted, which keeps the route in short. It does not change the shape of the service, since billing stays prepaid and support stays on email and help centre.
Strong eSIM
What does Strong eSIM cost at the start?+
Entry sits at $3.50 on a prepaid local or regional starter plan with a small data allowance and a short validity. Global Unlimited is $14.90 for each travel day and is also prepaid by the day. Nothing renews on its own, so the cost of a trip is worked out before you buy rather than at renewal.
Is there a monthly or contract plan?+
Every plan is prepaid on a short validity, so there is no monthly bill, no contract term and nothing to cancel. You buy the days you expect to need, and the plan ends when the validity does. Longer stays are handled by taking a fresh plan rather than by setting up a recurring one.
