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

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 !

Excellent service at a great price Excellent service at a great price. Kept me connected in London and again in Ireland at a fraction of the cost of my US network.

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.
