MyYoufone

One of the worst apps for internet/phone services that I have ever seen. I feel like I'm in the early 2000s while using the app. The haptic experience, the constant disappearance of the entry fields under the digital keyboard... Terrible. I'm not even talking about "not having an English UI". The only good thing is the friendly service personnel on the chat - and even that is half a star worth, because some of the folks just answer with a canned answer to win a point and close the "ticket".

In 1 word: terrible. - Data left for this month: doesn't update often (like twice a day or so), so you basically never know how much is really left when you need it most. - Unlimited data is not really unlimited data. At some point (I think it was after 5GB) they block data roaming. Unblocking took 2 years and many phone calls in which they promised it was now really solved. - After each update of the app you need to enter your credentials again. - Bugs are not fixed.

In the first month of my contract went severely over budget because the datalimkt is off by default and you have to pay for it. 100eur later decided not to complain and increase the data amount for the contract. This was very easily done in the App, but it doesn't tell you you will lose all benefits and discount that came with the original contract. After contacting them nothing could be done to help. They will squeeze any penny they can even if it is unreasonable. Avoid like the plague.
