Hi everyone, excuse my English, I'm french,
So I do use this library to send USSD from up to three different sim cards.
So I have three gsm modems connected to my computer and
I'm also able to send USSD over one of them (using Huawei E3131) but the others modems (Alcatel X602D and ) give me this error :
+CME ERROR: operation not allowed.
What should I do? Is there any kind of authorization I should give to my app?
