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.
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.

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.
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.
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.
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.

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.
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.
