Same as other o2 brand "Radost" this app is full of bugs. Same errors on both my phones when I try to turn on/off some services. On prepaid card, when you run out of your credit for subscribed service, it will auto turn on option for one day internet without possibility to turn it off and it will do it every single day until your account is 0eur. App will then logout you, widget will create errors and you'll be SMS spammed to renew credit. Bad experience overall.

Great experience? no way. Bad working cache forces you almost everytime to do operations over sms (refresh does not work, neither deleting app cache). Useless notification(it never show right numbers), the type of notification could be like google weather or translate. I will be happy to add stars after you fix the problems. Your generic answer does not work :( .
