Why ByteSIM?
We’ve used ByteSIM in 13 Countries now and have been impressed overall. Here’s why…
Affordable & flexible plans
You can certainly customize your ByteSIM plan to exactly the way you want it. We have mostly used the specific data amounts per day, for example 1 GB/day, which is quite unique and very useful. You can also buy the traditional fixed data packages too and the best part, they tend to come in at quite significantly under $1 per GB.
Calls & SMS included on some plans
Many travel eSIM plan options begin and end with internet data. ByteSIM gives you the option of purchasing plans with both calls and SMS in some countries, some also come with local phone numbers too. Very useful.
Live support

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.
