Pros and cons
BambooSIM
Pros
- Runs on Local partner networks, e.g. KDDI (au) and SoftBank in Japan, so your phone joins a local carrier instead of roaming on a home network
- eSIM is available across the plans, so there is no plastic SIM to collect and no store visit
- 5G is supported and hotspot sharing is available, so a phone can tether a laptop while travelling
Cons
- Data rollover is not available, so unused data is lost when a plan ends
- Wifi calling is not available, which matters where a local partner network has patchy indoor coverage
- Support runs on help centre, email and chat only, with no voice line listed
ESIMZON
Pros
- Unlimited plans start at $2.90, the strongest figure in that column of our data.
- Entry plans start at $1, and the UK range is prepaid with no contract, so a plan can end with the trip.
- Coverage spans 130 countries, so one plan covers a multi-country trip.
Cons
- It works as a reseller, so the host network behind a plan is picked for you rather than chosen.
- Support runs on email, chat and help centre, with no phone line for problems that matter while a trip is already under way.
- Billing is prepaid, so the range holds no long monthly plan for anyone who wants one steady recurring bill.
Who each suits
BambooSIM
Who it suits
- Travellers buying data before arrival rather than shoppers for a local contract
- People who want an eSIM on a local network instead of roaming on a home SIM
- Readers who prefer prepaid plans with no contract term
Who should look elsewhere
- Anyone who would rather buy from a reseller than an MVNO, since ESIMZON and KnowRoaming are both listed as resellers
- Travellers who need wifi calling, since it is not available here and the alternatives on the shortlist carry a different seller type
- Anyone who expects a quoted rate to stay put, since prices can be adjusted on notice for current subscribers
ESIMZON
Who it suits
- Travellers who install an eSIM before departure and want a plan that ends with the trip: entry plans start at $1 with no contract.
- People crossing several borders on one plan, since coverage spans 130 countries across partner networks.
- Readers who already own a handset and want data only, because the range is sim only and esim.
Who should look elsewhere
- Readers who want an MVNO rather than a reseller, such as co-sim, since ESIMZON works as a reseller.
- KnowRoaming, which lists entry at $1.75, if you would rather weigh a different price list, or BambooSIM, an mvno, if that model matters more to you.
- Anyone who needs a phone line, because support runs on email, chat and help centre and reaches you in writing only.

Questions about each
BambooSIM
What does a BambooSIM plan cost at the start?+
Entry pricing starts at $4.95, and the Unlimited eSIM plan is priced at $8.95. Every plan is prepaid with no contract, so there is no introductory rate that quietly renews higher later. What you pay at purchase covers the plan you chose, with the reference plans offered at set data or speed limits.
Is there a contract or an early cancellation fee?+
There is no contract. Billing is prepaid, and the reference plans are all sold as prepaid eSIM plans with no contract term, so there is nothing to cancel and no notice period to serve. You are tied only to the plan you buy, though prices can be adjusted on notice for current subscribers.
ESIMZON
What is the cheapest way to get data in the UK from ESIMZON?+
Entry plans start at $1 and are prepaid with no contract, so nothing carries into the next period. The capped-data UK eSIM plan is the lighter option, while the UK unlimited eSIM plans suit heavier use. On our price data, entry sits at 2 of 15 brands.
How much do the unlimited plans cost?+
Unlimited plans start at $2.90, and ESIMZON ranks 1 of 7 brands on that figure. The UK eSIM page lists those unlimited plans alongside a capped-data plan, all prepaid with no contract. Longer monthly plans are not listed, so a heavy monthly user has fewer options here.
