absolutely horrible as this app took 40 bucks because of the daily plan I paid for once and they silently didn't even bothered to try to pause data they simply silently took 40 bucks because of automatic top up

Hello, this app itself can not take any money from you. You can use the app for payments for 4ka services. In this case, we think that you used your credit on mobile phone data. Please contact us here and we will check it for you. www.4ka.sk/napiste-nam

Application looks nice and modern, UI is quite clean and all informations are easy to find and read. Paying for services is easy, prices are quite ok. Signal strength is really variable and good coverage is mostly in big cities.
