Our verdict

International SIM by Bouygues Telecom suits travellers who want a single carrier eSIM across regional and global trips. Entry plans start at $1.90, coverage reaches 200 countries, and support runs on email, chat and phone. The trade-off is that unlimited data is not offered, so heavy use calls for a top-up.

Pros and cons

Pros

  • Coverage reaches 200 countries, ahead of Cherry Roam at 150 countries
  • Entry plans start at $1.90, below Travelist WiFi at ¥770
  • 5G and hotspot sharing are both available, so tethering works on the same eSIM
  • Sold as a carrier plan rather than a resale marketplace, with a named legal entity
  • Top-ups are available, so a long trip can be topped up instead of repurchased

Cons

  • Unlimited data is not offered, so heavy streaming and navigation draw down the allowance
  • Reference plans for France, Spain, Italy and the UK start well above $1.90
  • Coverage of 200 countries ranks mid-field against 302 brands on reach
  • The Japan entry tier sits apart from the cheapest plan at $1.90, so price comparisons need care

Who it suits

  • Travellers crossing several European countries who want one carrier plan
  • Long trips where a top-up is likely to be needed
  • People who want 5G and hotspot sharing on the same eSIM

Who should look elsewhere

  • Travellers who need unlimited data, since this brand does not offer it
  • Buyers chasing the lowest entry price, where Superalink eSIM lists $0.79
  • Anyone settled on a narrower reach, such as Cherry Roam at 150 countries

Where it works

The eSIM reaches 200 countries across the trips it is built for. Plans come in regional and global formats, so a regional plan covers a single area while a global plan covers an itinerary that crosses borders. In the United States the service runs on AT&T and Verizon, and 5G is supported.

Speed and data limits

Unlimited data is not offered, so every plan runs on a fixed data allowance that you choose at purchase. 5G is supported, which keeps maps, video calls and browsing quick on a covered network. A fixed allowance suits travellers who browse, message and stream in moderation rather than those who plan to rely on the connection as their main line for the whole trip.

Price per GB and validity

Entry plans start at $1.90. Reference plan prices vary by destination: the United States is the cheapest entry tier, while France, Spain, Italy and the UK share a higher starting price and Japan sits on its own tier. Validity follows the length of the plan you pick, so a short trip pays for a shorter allowance.

How it compares on our data

On countries covered, the eSIM ranks 8 out of 302 brands, so the reach is solid without sitting at the front of the field. On price from, it ranks 50 out of 296 brands, a fair entry figure rather than a headline one. Read together, the two positions describe wide coverage at a mid-range starting price.

Setup and top-up

The eSIM is sold through a marketplace listing, so you pick a plan for your destination and install the profile on an unlocked phone. Listed features cover 5G, hotspot and instant activation, so there is no waiting period between purchase and connection. Hotspot sharing is available, letting a tablet or laptop share the connection, and top-ups are available for longer stays where the first allowance runs out.

The company behind it

The service is run by CG COMMUNICATIONS, a French company based in France. It operates as a carrier rather than a third-party resale marketplace, so the plans come from a single provider instead of several sellers. Support runs on email, chat and phone, which covers email, chat, phone and a help centre for setup questions or a top-up while abroad.

How International SIM by Bouygues Telecom compares

Frequently asked questions

How much does an International SIM by Bouygues Telecom eSIM cost?+

Entry plans start at $1.90, and reference plan prices differ by destination. The United States is the cheapest entry tier, while France, Spain, Italy and the UK share a higher starting price. A Japan plan with a larger data bundle is listed at $20.90, which is a useful anchor for judging value over a longer stay.

How many countries does the eSIM cover?+

The service reaches 200 countries, which is wider than Cherry Roam at 150 countries. In the United States it runs on AT&T and Verizon, and dedicated plans are listed for France, Spain, Italy, the UK and Japan. That spread suits itineraries that cross several borders in one trip.

Is unlimited data available on these plans?+

Unlimited data is not offered on these plans, so each one runs on a fixed allowance chosen at purchase. The listed feature set covers 5G, hotspot and instant activation, and unlimited data is not part of that line-up. Travellers who expect heavy streaming or constant navigation should compare rivals that do list unlimited plans before buying.

Can I use the eSIM for hotspot sharing and 5G?+

Both are supported. Hotspot sharing is available, so a tablet or laptop can share the phone connection, and 5G is listed among the plan features. The feature set covers 5G, hotspot and instant activation with instant activation, so tethering and fast browsing need no separate add-on once the eSIM is active.

How do I get the eSIM set up and activated?+

The service runs as a marketplace, so you choose a plan for your destination and receive the profile to install on an unlocked phone. Instant activation sits in the feature list at 5G, hotspot and instant activation, and the plan is a carrier plan rather than a third-party resale listing, which keeps the setup path short.

What happens if I run out of data on a long trip?+

Top-ups are available, so you can add data during a longer stay rather than buying a fresh listing from the marketplace again. Because unlimited data is not offered, a top-up is the practical route when the initial allowance runs out mid-trip, and it avoids a second purchase at the destination price.

Should I buy a regional or a global plan?+

Plans come in regional and global formats, so a regional plan suits a single trip inside one area and a global plan suits an itinerary that crosses borders. The service reaches 200 countries overall, and the format you choose decides which networks serve you at each stop on the route.

Who runs the service and how can I get help?+

The provider is CG COMMUNICATIONS, based in France, and it sells as a carrier rather than a marketplace. Support runs on email, chat and phone, which covers email, chat, phone and a help centre, so setup problems or a needed top-up have a direct line while you are abroad.
