Sim not working

Bought a sim, activated on the plane, came to Fiji - sim not activated and I can’t activate it either. 24/7 help is not responding.

Worked great

I used two plans. One for a week in the Jungfrau in Switzerland where it connected flawlessly with Swisscom and then a different plan for the UK which also worked well. Easy to install and reliable service. I had previously tried using Nomad as that service is highly rated but Nomad’s installation process, customer service, and connectivity were atrocious. Highly recommend ByteSIM.

Good Value & Performance

The reason why bytesim is cheap is because they are using international roaming agreements and centralised internet gateways located outside the country your visiting. This means the only downside is higher latency. Visited Costa Rica, I can see my internet traffic to google goes to London and breaks out there. latency is 300 -400 ms

Best eSIM Provider

Just thought to leave a review as I have been using these guys since 2022. They have been absolutely great for very cheap prices on international trips all around the world from Europe to Africa and Asia. I am just about to go to Kyrgyzstan and will be the true test for ByteSIM. But so far they have been incredible especially once you get the hang of activating the eSIM and following the simple steps (it can be a little confusing at first.)

High quality service, budget price

I’ve used Bytesim for a number of years for trips across Europe, Asia and Australia. Each time, setup has been simple and the subsequent service has been fast and flawless. I have not needed to consider using an alternative eSIM provider. Thank you Bytesim!

Unreliable connection and poor customer service

Disappointing experience during a 20-day trip. I purchased a 20gb data plan with unlimited calls and texts, but experienced repeated call drops mid-conversation across 7-8 different phone numbers, with multiple failures happening on the same day. I also had sudden network outages where I couldn't connect to the internet for several minutes at a time throughout the day.

When I contacted customer support with detailed evidence (screenshots of dropped calls, specific phone numbers affected), they were dismissive and repeatedly blamed "signal conditions on the receiving party's end" despite the pattern occurring consistently across multiple different numbers and days. They refused to acknowledge it could be a service issue on their end and denied any refund.

The unreliable calls made it genuinely difficult to make reservations and communicate during my trip. If you need dependable voice calls while traveling, I'd look elsewhere. calling feature they advertise as "unlimited talk" was unreliable when I needed it most.

I have been using this app for couple of years. Best esim so far.

I have tried many esim, among them this one is the best and cheaper one. I have been using this for more than a years.
Bad thing is you need new esim for every country, so spend wisely, calculate your stay and only buy otherwise it could be expensive.
Costumer service through whatsapp also very helpfull.
If it becomes global and unlimited expiry date, it could be the No. 1 esim app in the world. Hope it will become soon.

Steer Clear.

I usually avoid writing negative reviews but this time I must warn you to steer clear. The service they advertise simply isn’t delivered and their customer service is actively working to prevent refunds. I tried the service twice and unfortunately I haven’t been able to use either time. Others services have worked first time but not ByteSim. Once bitten twice shy.

Internet is very slow

I was using bytesim in Asia and it worked well, but in Europe and Mexico the internet is so slow that you can’t even open the app

お金の無駄だから利用しないで。

私達は3日間のラオスの旅で利用しました。
街、田舎どこでも接続は悪く、QRコード支払いにはいつもお店のWiFi を利用しなければならなく、とても不便でした。
2度と利用したくない会社です。

No hassle, great service!

No need to go through complicated settings, or fumbling around. Simple, reliable service, which seems comparable to any as you might expect from T-Mobile or other major carrier!

Slow speed

Unreliable speed and coverage

No more China VPN

Was happy for a while as the China Esim came with a built-in VPN. But not anymore, so really disappointing

No real unlimited

I got an esim with „unlimited“ 5G data plan and tried to used it in germany. It connects to O2 provider, i got 20mbits 1m next to my friends phone which is getting between 200-250 connected to the same radio mast through the same provider. After using 5GB the internet got blocked and wasn usable anymore even with best network recieval and healthy connection

Horrible customer service

Bought a package which should have included a number, it did not. Contacted support through their WhatsApp service and they had horrible support. They even refused to give a refund even though I requested it within an hour of purchase.

Horrible company, use any other eSIM service.

Bought 5G Unlimited but not working

I purchased 5G Unlimited plan for 3 days for my MY trip, internet stopped working after one day and the app shown 12.55GB of usage. I don't mind if it stated clearly about the FUP so I can better plan everything out, but got data stopped only after a day caused so much problem for my trip.
