To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience.

I was happy with the service, right up until the time they discontinued it and didn't bother to let me know. I bought the DataMax sim card and have been using it in Panama for 6 months. Paying a... See more

QR code failed to arrive to mail or junk. Follow up email got response a day later with replacement code. SIM worked fine, but connection was poor. It was data only.
However, it was certainly better than nothing! So, thank you.

Working but really poor service

Working but really poor service,

2 advice if you buy on this website, don't leave payment page or go back on it with your history if you not receive emails,
And if internet is not working check the APN settings yourself.

I buy esim for Vietnam so first I never received any email, to find the QR code I had to go back to payment url and refresh it to finally get it but not any email,
After this when I arrived Vietnam esim is not working, no internet, so I look how the APN settings are done but nothing is correct I have to use airport wifi and find it online to do all settings myself, but for someone who doesn't work in telecommunications it would be very difficult.

Really complicated for such a service !

Partially unsatisfactory

Good: purchase and installation of eSIM was easy. Convenient pricing.

Unsatisfactory: Ramdomly data rate was dropping to allmost zero (sometimes for hours, sometimes minutes).

Couldn't get esim to work in Vietnam

Couldn't get esim to work in Vietnam, desperately bought another one from Onesim - same issue, wouldn't register on network. Bought another from a different provider and it worked straight away. 2x money wasted, happy to provide details of other provider if anyone wants it

If I could give a zero rating …

If I could give a zero rating, I would. I have no idea what went wrong, but you charged me for an eSIM you never delivered (refund email sent for order 18807). I sent an email for help on 31 Mar that was never answered. Customer experience doesn’t get much worse than that unless you burn my house down.

Overall, bad signal and no customer service.

I have also contacted your customer service, but did not get any assistance.

The signal went of frequently, while other people around me had data.

I often was trapped, when needed signal / data.

Website and google maps loaded slowly.

Wonderful service with minor hiccups

Wonderful service with minor hiccups
It was a great experience from start to finish. However, there was no way for me to purchase (or at least from what I could see on the website) a smaller amount of data for when I ran out. I think there should be an option for that.
