Why can't I get on qq or even send messages?

This situation may be a network problem.

1, check your network problems first.

2, mobile qq can't send or receive messages, check whether your mobile phone is in arrears.

3. If the mobile phone is not in arrears and the network is unblocked, it may be a system problem. Log off and try again.

Note: If none of the above methods work, you can try to turn off and restart your phone.
