Pros and cons
Pros
- Plans start at $0.79, which puts Superalink eSIM among the cheaper entries in the eSIM range.
- Unlimited data is offered, and 5G is available, so a heavy browsing day does not force a top-up.
- Coverage spans 150 countries, and regional and global means single-country and wider plans sit in the same catalogue.
- Support runs on email, chat and help centre, including a help centre for questions before departure and during a trip.
- The seller behind the plans is a named company, GADGET SG PTE. LTD., based in Singapore, which is a baseline worth checking before you pay.
Cons
- Support runs on email, chat and help centre, and a phone line is not among those channels.
- Unlimited data plans come with a fair use condition attached, and Speed reduced after daily quota; full speed resets next day.
- $0.79 is an entry point for a single-country plan, while the wider regional and global range sits above it.
- At 150 countries covered, the catalogue stops short of the widest global reach on the market.

Scored 9.6 / 10 by NomadCue.
Who it suits
- Travellers on a short trip to a single destination who want data ready before landing rather than a shop queue.
- Backpackers and repeat Asia visitors who need unlimited data and 5G across several markets in a single purchase.
- Readers who would rather read a help centre article or send an email than wait on a support line.
Who should look elsewhere
- Anyone chasing the widest country list in a single purchase, where a broader global catalogue serves better.
- Travellers who prefer a hardware pocket WiFi device from Travelist WiFi that works without a phone.
- Buyers who need a phone number for support, since chat and email are the routes on offer.
Coverage and networks
Superalink eSIM covers 150 countries, and 5G is available. Plans are organised by regional and global, so a single-country plan, a regional bundle across several Asian markets and a wider global option sit side by side in the same catalogue. The Japan listing states 5G plainly, and the same pricing structure appears for Thailand, which is how a multi-country Asia trip can be covered with a single purchase rather than a plan per country. Read the country count as a snapshot of the catalogue rather than a promise for a specific route, and check that the stops on your itinerary are on the list.
What data costs
Fees start at $0.79. The reference plan prices show Japan and Thailand at the same entry level, while the wider Asian bundle costs several times that amount, which is the clearest illustration of how price behaves once a plan covers more than a single market. On price per GB, the cheapest plans on the site run at €0 while the median across the comparison sits at €1.49. Daily rates and plan length change the picture again, so weigh the destination plan rather than assuming a single rate applies everywhere.
Speed and fair use
Unlimited data is offered and 5G is available, so there is no need to ration a fixed allowance on those plans. The catch sits in the fair use terms: Speed reduced after daily quota; full speed resets next day. That means a heavy day of maps, video and hotspot use can still reach the daily ceiling, and the return to full allowance only arrives with the next daily window. Anyone who needs a guaranteed connection for a full day of calls or streaming is better served by a fixed allowance plan. Where unlimited data is not needed, the per GB pricing above is the number to weigh.
Where it sits among rivals
On price from, Superalink eSIM sits at position 6 out of 296 brands compared, which is where the catalogue earns its place. On countries covered it ranks at position 103 out of 302, well short of the leaders on reach. The trade-off is straightforward: this is a cheap, easy entry rather than the broadest shelf. For a single destination the low price usually decides it, while a multi-country trip is better served by a catalogue built wider.
Who runs it
Superalink eSIM is run by GADGET SG PTE. LTD., headquartered in Singapore. Support runs on email, chat and help centre, so questions are handled by email, live chat and a help centre rather than by phone. The help centre is the channel worth opening first, since plan and fair use answers live there. The named legal entity on the terms and conditions is the detail to keep, as it tells you which company stands behind a plan bought for a specific destination.

Frequently asked questions
How much does a Superalink eSIM cost?+
Plans start at $0.79. The reference prices show Japan and Thailand at the same entry level, while a multi-country Asian bundle costs several times more, so a regional plan is a different outlay from a single-country purchase. Check the destination plan rather than relying on the entry price.
What is the price per GB on Superalink eSIM?+
The cheapest plans on the comparison run at €0 per GB, against a site median of €1.49. The spread runs as far as €87.61 per GB, so the allowance and the plan length matter more than the entry price alone.
How many countries does Superalink eSIM cover?+
Coverage runs to 150 countries, and 5G is available. Plans are organised by regional and global, so you can buy a single-country plan, a regional bundle or a wider global one. That sits below the widest catalogues, so check the country list for your route.
Is the unlimited data really unlimited?+
Unlimited data is offered, with one condition attached: Speed reduced after daily quota; full speed resets next day. Nothing stops you using the data, but the daily quota is what the condition turns on. If you need a steady connection for calls or streaming, a fixed allowance plan is the safer choice.
Does Superalink eSIM support 5G?+
5G is listed among the features alongside unlimited data, and the Japan plan states it directly. Availability depends on the country you pick and the network you land on, so read the destination plan before paying. Older handsets will simply stay on the older networks.
How do I get help from Superalink eSIM?+
Support runs on email, chat and help centre, which means email, live chat and a help centre. A phone line is not among those channels, so chat or email is the route for anything urgent. The help centre is worth reading first, since plan and fair use answers sit there.
Who is behind Superalink eSIM?+
The plans are sold by GADGET SG PTE. LTD., a company headquartered in Singapore. That legal entity also appears in the terms and conditions, so it is the name to look for when you want to know who stands behind a plan. It serves travellers rather than selling a local carrier plan.
Is Superalink eSIM cheaper than USim or AirZlink eSIM APP?+
On entry price, yes. Superalink eSIM starts at $0.79, while USim starts at $1.46 and AirZlink eSIM APP at $1.76. A Travelist WiFi pocket device starts at ¥770 and is a different shape of product, useful when you need a router away from your phone.
