Works well. It's just a little bit annoying, that details for the current chosen option are not shown in detail

Why does tarif change takes 4 days to complete? Is it intentional that the network operator wants to double charge ? I had a Basic Tariff ending on 12 November. An hour before the end, I chose a new tariff plan. According to my previous experience, such a change came into effect in less than an hour. Yesterday, after the change request, I received an SMS saying that the new tariff plan would take effect on 15 Nov, while the current Basic tariff was renewed and charged. This is double charging!

Don't lose your time to buy a sim card on market.... Takes a lot of time to try to activate a mobile number... and in the end you should go to register.... Why don't write down when you sell it prepaid sim card not registered.... and the steps that should be taken to activate it.... Guys if you are in Germani better if you go directly to the store of each company to purchase a sim card then loosing time with prepaid market cards and useless app tools.
