OnesimReviews of onesim.co

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, 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.

Couldn’t even install card as QR code issued was invalid.

Very Satisfied

We can't top app any esim.

i cannot esim activated

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 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.
