### 5/5 — Used in Japan with no problems!

*2026-06-02*

Saw some bad review, but decided to give it a try. I only need it for 7 days, figures $10 lost is not gonna kill me. And I can always get something else if this on not working. Turn out I have nothing to worry about, activated before the trip. Turn my T-Mobile whim off. This card tools over. Unlimited data, never have to worry about getting throttled. A lot of time works better than other free WiFi at locations. Thanks

**Developer response:** Thank you for sharing your experience! 😊

We’re really glad to hear that the service worked well for you and helped make your trip smooth and hassle-free. Your feedback and trust mean a lot to us.

We’ll continue working hard to maintain reliable service and support for all our users. Thank you for choosing Xummer eSIM!

### 1/5 — irresponsible customer service and useless app

*2025-10-31, version 1.3.7*

The package I bought have problem , can’t activate at all , texted the seller many times but unresponsive, at the end the customer service just ignore my message when I asked for refund , please don’t use this app

### 5/5 — EASY

*2025-10-12, version 1.3.6*

Omg this helps me when to travel! Only install 1 times so hard put redeem code. After that if i want to travel i can just purchase inside~

### 1/5 — So expensive

*2025-10-12, version 1.3.6*

RM100 gift voucher is a scam strategy, not a single voucher but multiple small amount vouchers with minimum amount of spending, avoid

### 1/5 — Can’t login to the app

*2025-09-27, version 1.3.6*

Can’t login to the app

### 3/5 — Not reliable

*2025-09-23, version 1.3.5*

I used this eSIM before in Bali and it worked perfectly, no issues at all. Thought it would be the same in Hanoi, but nope—no coverage the whole time. Tried contacting customer service and got nothing back. Totally wasted my money this round.

### 1/5 — 客服也不回复

*2025-09-18, version 1.3.5*

购买了流量也不能用，客服也不回复，差评！不推荐！一颗星都不想给！

### 5/5 — GOOD

*2025-09-18, version 1.3.5*

Good easy to use nice

### 4/5 — CUSTOMER SERVICE NOT AVAILABLE

*2025-09-13, version 1.3.5*

scam

### 1/5 — Not functioning

*2025-09-12, version 1.3.4*

This is the first time I download the app and it only lands at the picture, not even the home page! I can’t click anything at all! This is ridiculous and I reached out to support team nobody is entertaining. This is extra frustrating as I’m the reason I buy eSIM is I will receive it almost immediately.

Please fix the app as it is not loading at all.
