Dear Lyse, We're sorry to hear about your experience. If the data allowance of a plan is fully used, the connection will stop working unless additional data is purchased. Usage can depend on activities such as streaming, video calls, or app updates, so the allowance can sometimes be used faster than expected. We understand your frustration and appreciate you sharing your experience.
I bought 10 GB for a week in malta
I bought 10 GB for a week in malta, but the third day the offer had expired without letting me know, i then found an email by ubigi telling me i had finished the 10 GB in two days, which seems impossible to me since only two days had passed and each time i checked the app it told me i had only used a couple hundreds MB.

Super simple to set up
Super simple to set up, easy to use and worked well in Finland. The only difficulty was when I turned my phone completely off I had no idea how long it would take to log back in. You have to be on wifi to even get logged in to see.
It was the second time I used Ubigi…
It was the second time I used Ubigi abroad, once in Georgia and lately in Germany. It's very easy to use and works very well. I was surprised how few data it uses when the e-sim is on, even letting it running non-stop.

Two out of the 4 services I got didn’t work when we arrived at the airport
The setup was tedious
The setup was tedious, lengthy, and confusing. The actual running speed is rather slow. I wish the process could be much simpler when I arrive in Vienna next time.
Great support when you have occasion trouble.
Never do but had some trouble accessing the eSIM this time. Customer service was friendly and promptly fixed my problem.
