### 1/5 — Unreliable connection and poor customer service

*2026-08-09*

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.

**Developer response:** We sincerely apologize for the connectivity and support issues you experienced. We want to make this right. Please message us on WhatsApp at +85292900577 and we will process a refund for your plan.

### 1/5 — Internet is very slow

*2026-06-23, version 3.0.17*

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

### 1/5 — お金の無駄だから利用しないで。

*2026-06-22, version 3.0.17*

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。

### 5/5 — No hassle, great service!

*2026-06-21*

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!

### 1/5 — Slow speed

*2026-06-11, version 3.0.16*

Unreliable speed and coverage

### 3/5 — No more China VPN

*2026-06-02, version 3.0.12*

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

### 1/5 — No real unlimited

*2026-05-24, version 3.0.11*

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

### 1/5 — Horrible customer service

*2026-05-21*

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.

**Developer response:** We sincerely apologize for the negative experience you had with your purchase and our support team.Could you please provide your Order ID? We will look into this immediately and help you get this resolved.

### 1/5 — 中國廠商

*2026-05-15, version 3.0.11*

用下影片就限速，吃到飽方案白花的5g跟4g一樣慢

### 1/5 — Worst service dont buy

*2026-05-01, version 3.0.4*

The worst esim service i ever bought
I never posted a review for any app before but this one worth the review as its extremely bad
Keep on disconnecting 
It ruined my trip
Totally waste of money and time
