XR: How do two telecom cards receive short messages (it's not that kind of switching card numbers, it's too troublesome)?

1. You can switch the Internet access function of the mobile phone card, just switch the Internet card to the telecom card in the settings of mobile phone-dual card and mobile network-default card.

2. If you can't access the Internet after switching, you can try restarting your phone.

Maybe your telecom card is in arrears and you can't surf the Internet.
