Pros and cons
Pros
- Coverage of 135 countries across 350+ partner networks
- Unlimited data, hotspot sharing and instant activation all sit in unlimited data, hotspot and instant activation
- Regional and global plans (regional and global) fit both short trips and longer stays (short trip and long trip)
- Fixed packages start low, with reference prices from $11 in Europe
Cons
- Support runs on email and help centre only, so there is no phone line for quick questions
- Unlimited plans follow a fair use policy: usage runs unthrottled to a threshold, slows past it, and data can be closed above a higher mark
- Prices vary by destination, from $11 in Europe to $34 in Japan
Who it suits
- Travellers crossing several borders who want one eSIM instead of a new SIM in each market
- People who tether a laptop or tablet and need hotspot sharing on the same plan
- Long-stay travellers who will top up the same eSIM rather than repurchase
Who should look elsewhere
- Anyone chasing the widest country list: Zwitchy covers 200 countries
- Buyers after the lowest entry price: eSIMGo.is lists plans from $0.99
- Travellers whose trip is confined to Israel: SimToIsrael prices from $25
How it compares on our data
On countries covered, the brand ranks 99 of 303 compared brands. Entry price sits at 181 of 313, closer to the middle of the field. The per GB rate is the stronger side, at 35 of 115, so heavy users fare better here than light ones.
The company behind it
TravelSIM runs through Top Connect OÜ, registered in Estonia, and has been selling travel data since 2006, so it is an established operator rather than a new storefront. Support comes through email and help centre: the help centre first, email for anything more detailed.

Frequently asked questions
How much does a TravelSIM Mongolia plan cost?+
Entry plans start at $7 and the headline price per GB runs from $1.10. A small package suits a short hop, while heavier use is better served by a larger allowance or one of the unlimited plans, which sit alongside the fixed packages.
What do reference plans cost in the US, Europe and Japan?+
Reference packages differ by destination: $13 in the US, $11 in Europe and $34 in Japan. Japan sits at the top of that range, so travellers heading there pay more. Regional and global plans (regional and global) spread cost across a trip with several stops.
Is the unlimited data plan really unlimited?+
Unlimited plans sit in unlimited data, hotspot and instant activation, but they come with a fair use policy. Normal usage is counted each month, the first stretch runs unthrottled, the next band is slowed, and past a higher threshold the data can be closed. Read the terms before committing to a long stay.
Can I share the connection with a laptop or tablet?+
Hotspot sharing is supported and listed in unlimited data, hotspot and instant activation alongside unlimited data and instant activation, so another device can share the connection. Keep the fair use policy in mind on unlimited plans, since heavy tethering counts toward the same thresholds that slow or close data.
How many countries can the eSIM cover?+
Coverage spans 135 countries, with 350+ partner networks behind the service. That is a wide list for a trip crossing regions, and a regional plan can hold several of those markets under one eSIM. Check the destination list before buying if the route depends on a specific border crossing.
How do I set the eSIM up once I land?+
Setup is instant, since instant activation is part of unlimited data, hotspot and instant activation. Buy the plan before departure, then install the eSIM on arrival and join a partner network. If anything goes wrong, support runs through email and help centre, so the help centre and email are the routes to use.
Can I top up while I am still travelling?+
Yes, top-ups are available, which helps when a trip outlasts the validity on the original package. Add data to the same account instead of buying a fresh eSIM, and watch the fair use policy if the top-up sits on an unlimited plan. Support runs on email and help centre if a purchase needs checking.
Who is behind TravelSIM Mongolia?+
The service is sold by Top Connect OÜ, based in Estonia, and has been trading since 2006. Plans come in regional and global shapes (regional and global) for short trips and longer stays (short trip and long trip), so the same operator covers a quick city break and a multi-country route.
