Hello, if your mobile phone can't answer the incoming call, you can troubleshoot in the following ways:

1 Check whether the mobile phone is in arrears, and suggest paying for recharging;

2. Check whether the mobile phone is set with call forwarding, flight mode on and call barring. Suggest canceling and try again;

3 Check whether the function or signal of the mobile phone is normal. It is recommended to change your mobile phone or location and try again.

4. If roaming to other places can't be used, it is recommended to check whether the local network signal is normal and whether roaming permission is enabled for this number;
