Our verdict on each
co:sim
co:sim suits travellers who want a prepaid eSIM with wide reach and a low starting price, and plans open at $0.99. It is a data-only setup, so the eSIM, hotspot sharing and sim only options suit people who manage their own data rather than expect a handset with the plan.
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
co:sim
Pros
- Entry at $0.99 puts co:sim at the front of the price ranking: 1 of 15.
- Reach of 200 to 240 countries with hotspot sharing, so one data plan can carry a phone and a laptop across a long route.
- Sim only eSIMs on prepaid billing, so nothing is locked into a contract before the trip: prepaid.
Cons
- Billing is prepaid only, so a long trip has to be bought and paid for up front rather than spread over a contract.
- Unlimited daily data costs $13.99 against an entry price of $0.99, so wide-area cover for a long route sits well above the figure a plan list opens with.
- Of the email, chat and phone on offer, phone is the least common: 18.8% of the listings here include it, against 93.8% for the help centre.
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.
Who each suits
co:sim
Who it suits
- Travellers crossing several countries who want a prepaid eSIM and hotspot sharing.
- People who plan their own data and pay as they go, since billing is prepaid with no contract attached.
- Anyone with an eSIM-ready handset who wants a sim only plan.
Who should look elsewhere
- Travellers after a named local partner in a single country, such as a Japan trip, where BambooSIM runs on Local partner networks, e.g. KDDI (au) and SoftBank in Japan.
- Shoppers who prefer a reseller setup, since ESIMZON is reseller and KnowRoaming is reseller.
- Buyers who want a monthly contract to renew: billing is prepaid, and the listed plans carry no contract.
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.

Questions about each
co:sim
How much does a co:sim plan start at?+
The entry price is $0.99, and it belongs to a single-destination data-only eSIM rather than a wide-area plan. That makes it the figure that appears first in a plan list, but it is not the cost of staying online across a whole trip. Budget from the unlimited price for multi-country use.
How much is unlimited data on co:sim?+
Unlimited daily data costs $13.99. That plan covers a wide area list and runs without a contract, and it is the line most readers set against other sellers' unlimited plans. The gap between this figure and the entry price is the trade-off: unlimited removes the need to choose a data amount and moves the budget up.
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.
