Description

From the listing uploaded by “appupdater”.

What can you find in the application and how can it help you? In the overview of services, you can see the current status of your credit, drawing units from the prepaid NEŘEŠTO tariff or from packages (Minutes, SMS and Data). You will see exactly how many units you have left, when your prepaid tariff will be renewed, when you can top up your credit or activate a new package. In the application, you can easily choose one of the super prepaid tariffs NEŘEŠTO, you don't have to go anywhere, sign anything, you just attach your PAYMENT CARD and the tariff will pay for itself after 30 days. Or you mix the individual packages Data, Minutes, SMS yourself so that Cactus fits like a glove. For self-renewing packages, you can purchase extra data and turn off self-renewal. You can easily top up your credit here, so you won't miss any of our Facebook events, during which we add extra credit for topping up. If you do not want to search for a payment card every time you top up, all you have to do is activate the payment with one click and next time you just select the amount, click on top up and it's done :) Do you have friends at Cactus and do you owe him coffee, for example? You just send him fifty ducks from the credit via the apk and it's settled;) You can also look at the list of services, so you have an overview of when the prepaid tariff was NOT paid, how much the package cost you, when you topped it up, or where you called and for how much. Even when roaming, you have the data that the application uses for free. You can find more about the application and Cactus at www.mujkaktus.cz
