Pros and cons
Pros
- 190 countries covered, well past Cherry Roam at 150 countries.
- Unlimited data is offered and 2GB daily high-speed then unlimited at min 128 kbps keeps the connection usable after the daily high-speed allowance, so a group never hits a hard stop.
- Hotspot sharing is offered, so several travellers share one phone instead of buying a plan each.
- regional and global means regional and global plans sit in the same list, which suits a route that changes mid-trip.
- A 30 days money back window softens the cost of a plan bought too small.
Cons
- Top-ups are not among its listed features (unlimited data, 5G and hotspot), so a plan that runs short mid-trip has no refill on the same line.
- 2GB daily high-speed then unlimited at min 128 kbps leaves speeds at a minimum after the daily high-speed allowance, so streaming slows before the data runs out.
- Entry pricing of $2.50 sits well above Superalink eSIM at $0.79, and the rank on price from is 79 of 296 brands.
- Support runs on email, chat and help centre, so a traveller who needs to speak to someone has no phone line listed.
Who it suits
- Groups on a multi-country route who want 190 countries on a single plan.
- Travellers who share a hotspot instead of carrying a separate device each.
- Short trips where the daily high-speed allowance in 2GB daily high-speed then unlimited at min 128 kbps comfortably covers the days out.
Who should look elsewhere
- Superalink eSIM, if $0.79 is the entry price you need to hit.
- Cherry Roam, if 150 countries matches your route and the wider eSIMX map goes unused.
- Travelist WiFi, if a pocket device priced from ¥770 suits your group better than a profile installed in a phone.
Speed and data limits
Unlimited data is offered, and the fair-use line sets its shape: 2GB daily high-speed then unlimited at min 128 kbps. The high-speed allowance resets each day, and data keeps flowing afterwards at a much lower rate, so streaming and large uploads are what feel the limit first while messaging and maps carry on. 5G is offered, which counts for more in cities than on long rural stretches. For a group sharing one connection, the daily allowance is the piece to plan around.
Where it works
Coverage runs to 190 countries, and the plan list offers both regional and global scopes, so a single trip or a multi-country loop can be covered. Cherry Roam reaches 150 countries, which leaves a wide gap if the two are weighed side by side on reach alone. In the United States the service sits on T Mobile, AT&T and Verizon, a strong set of hosts for a route that crosses carriers, and 5G is supported.
Price per GB and validity
Entry pricing starts at $2.50. The reference prices list regional and global plans separately, with the regional entry points for the United States, Europe, Thailand and Turkey sitting below the global plan. For the same reference allowance, the United States is priced at $10.90, Europe at $8.80 and Japan at $9. Validity follows the scope you buy, so a short regional plan and a global plan cover very different trip lengths.
Setup and top-up
The feature set, unlimited data, 5G and hotspot, includes instant activation, so there is no wait between landing and being online, and hotspot sharing is offered, which is the detail that settles the plan for a group on the move. Unlimited data and 5G come with it. Top-ups are not available on the plans shown, so the allowance you pick has to last the whole stay rather than being extended later.
How it compares on our data
On countries covered, eSIMX ranks 57 of 302 brands tracked, which puts the reach near the top of the list. On price from, the rank reads 79 of 296, so coverage is the stronger argument and the entry price the softer one. Taken together, the picture is of a brand picked for where a group is going rather than for the headline figure.
The company behind it
The service is run by Skylark Connect LLC, based in the US, which gives buyers a named operator to look up before paying. Support runs on email, chat and help centre, so most questions get answered in writing or through a live chat rather than on a phone line. For a group sharing one plan across several phones, a written support trail is often the practical route.

Frequently asked questions
What does an eSIMX plan cost to begin with?+
Entry pricing starts at $2.50, and the reference list sets out separate regional and global plans. For the same reference allowance, the United States plan is priced at $10.90, Europe at $8.80 and Japan at $9. The regional entry points sit below the global plan in those reference prices.
Is the data genuinely unlimited on eSIMX?+
Unlimited data is offered, and the fair-use line is 2GB daily high-speed then unlimited at min 128 kbps. The high-speed allowance resets each day, so a heavy morning of streaming is followed by slower speeds rather than a cut-off. Maps, messaging and browsing stay usable, while video and large uploads feel the squeeze first.
Which countries does eSIMX actually cover?+
Coverage runs to 190 countries, and the plan list carries both regional and global scopes. In the United States the service runs on T Mobile, AT&T and Verizon, so a trip crossing states is less likely to meet an unserved patch. Cherry Roam covers 150 countries, a narrower map.
Can a group share one eSIMX plan?+
Hotspot sharing is offered, and the feature set, unlimited data, 5G and hotspot, puts unlimited data and 5G alongside it. That makes a single phone the hub for a group sharing one plan rather than buying a profile each. Instant activation is included too, so the hub comes online without a separate setup step.
Can I top up data part-way through a trip?+
Top-ups are not available on the plans shown, so the allowance has to cover the whole stay. 2GB daily high-speed then unlimited at min 128 kbps also reduces speeds once the daily high-speed allowance is used, which makes a long itinerary worth planning carefully. Short trips and regional plans suit that model better than a multi-month run.
Who runs eSIMX and where are they based?+
The service is operated by Skylark Connect LLC, based in the US. Support runs on email, chat and help centre, so questions are handled in writing or through live chat rather than on a phone line. Buyers who want a named legal entity and a written support trail have both here.
What happens if I pick the wrong plan?+
There is a 30 days money back window, which leaves room to change a plan after buying. It suits a group that has not yet settled on its regions, although top-ups are not offered, so the size chosen at purchase is the size the group has for the trip.
Does eSIMX run on 5G networks?+
5G is offered, and unlimited data, hotspot and instant activation all sit in the same feature set, unlimited data, 5G and hotspot. What you see in practice depends on the host network in each country, and in the United States the service runs on T Mobile, AT&T and Verizon, so coverage quality follows the carrier you land on.
