So the only way to wake up an application is through a server by sending silent notifications 😓 what if I create an alarm like the one on the phone to pick up the application and update those cases? Will it work? Why the alarm application ⏰ being still closed emits the alarm at the chosen time.I'm looking for a solution since it's not facial to pay for a server to raise an application when that should be done 💆🏻‍♂️

When you put card + card + pin + amount it gives you a ussd code example like this 4448902043434162136518048016167*1230628# which does not let you call and I have tried all kinds of methods

Hello, I am creating an application for the management of operations and banking inquiries since in the country where I lived they do not have the resources to do it in the ios community, so it consists of using the Sim, the ussd codes are executed, example 44404# es to start a section in a bank, then there are operations that exceed 50 characters, for example when you put 2 cards for transfer, each card has 16 characters, plus the pin of each card and the amount and it does not let you call
