Ratings and reviews

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!

good rate and good mobile network . highly recommended
