Xiaomi max2 mobile phone can't be dialed out, and others call in to show that it is turned off, but how can I get back if there is a network?

1, SIM card failure: First, check whether the SIM card is correctly installed in the mobile phone and ensure that it is not damaged or expired. Try to insert the SIM card into other supported phones and test whether there is a similar problem.

2. Network signal problem: Even if the mobile phone shows network connection, sometimes there will be poor signal strength or network failure. Try entering another location or turning on airplane mode, then turning it off and reconnecting to the network to see if it can solve the problem.

3. Communication service problems: Sometimes the operator's network problems will make it impossible to make calls or display incoming calls. After eliminating other problems, contact the operator for inquiry.
