Why International SIM by Bouygues Telecom eSIM?
We’ve tested their eSIM in 2 Countries now and here’s a breakdown of what we’ve found so far:
A travel eSIM backed by a company that actually knows telecoms
Most travel eSIM providers are resellers. International SIM by Bouygues Telecom is different because the infrastructure behind it comes from a company that’s been running mobile and internet networks for decades. If you’ve ever had a travel eSIM drop out at the worst possible moment, you’ll appreciate why that matters.
Flexible plans
Their plans are available for single countries or entire regions, covering 200+ destinations with 4G and 5G. What stands out is that many plans include calls and SMS too, which is still fairly rare in the travel eSIM world. There are also unlimited plans and a top-up option if you burn through your data faster than expected.
Buy now, travel later
Another cool thing about the International SIM by Bouygues Telecom eSIM is the 365-day activation window. You can purchase your plan well in advance and activate it whenever you actually need it, whether that’s the day you buy it or months down the line. It’s a small thing but it removes a lot of the last-minute stress that comes with sorting connectivity before a trip.
How did it perform in our real-world testing?
We tested across multiple locations in both countries, covering city centres, residential areas and on the move, before recording our peak speeds from the capital cities.
In the UK, out of 37 providers we tested, it came in second place with a top speed of 581 Mbps in London. Streaming, navigation and hotspot all worked well throughout our time there.
In Colombia, out of 32 providers, it ranked second again with a peak of 574 Mbps in Bogotá. We tested across different parts of the city and the connection was consistent throughout.
Finishing second in both markets, especially in Colombia where performance can vary a lot between providers, is a result we were genuinely impressed by.

How we test eSIMs
Speed Testing
We run 3 consecutive speed tests using Speedtest by Ookla in the same physical location with at least 3 out of 4 signal bars. If all 3 results fall within roughly a 15% download speed range, we record the highest result. If results vary more than this, we rerun the test to avoid random spikes or drops. This reflects realistic peak performance under stable conditions.
Stability Check
We use the eSIM normally over at least 2 to 3 days and note:
- Any full signal dropouts
- Whether reconnections happen automatically
- Whether any manual intervention is needed
If no issues occur, we state that explicitly.
Real-Life Usage Tests
We test every eSIM with common everyday tasks, including:
- General web browsing
- Google Maps loading and navigation
- WhatsApp messaging and media sending
- Uploading photos to cloud storage
- YouTube streaming (HD playback)
- Hotspot usage where supported, connecting a 2nd device
These checks confirm the connection is usable in real travel scenarios, not just fast in speed tests.
Customer Support Testing
We run quarterly support reviews across all providers using the same questions for each provider. We record and rate:
- Time to 1st human response
- Support channel used (live chat, email, WhatsApp)
- Whether the response is human or automated
- Whether the issue is resolved in the 1st interaction
- Overall clarity and usefulness of the reply
Support results shown in reviews reflect the most recent quarterly test.
