@Vuputhoy70 Actually you can see that in the Swisscom Cockpit, the problem here is, for the login you need to enter the mobile number and then you'll get a SMS with code you also so need to enter and which you can't read with the USB Dongle. Possible, you can enter the SIM Card into a mobile device to get and read the SMS with the code.

Alternatively you can check via MySwisscom -> Home -> Mobile, if you find the already used data there.
If nothing helps, I suggest to call the Hotline via 0800 800800 or via Chat
