Missed message reminder function is enabled. Why didn't I get a message reminding me of missing letters when I turned it on?

If the phone is turned off or stopped for more than 48 hours, and the short message cannot be sent to your phone, the network will discard the short message.

In addition, there are other reasons for not receiving missed messages: the business function of the call manager is realized through call forwarding. If the call forwarding set for the call manager is overwritten or fails for other reasons, you will not be able to receive missed messages from the call manager.

Treatment method:

Method 2: You can check whether the number is down first. If it is down, please recharge it in time. After recharging, it is recommended that you reset call forwarding (directly dial the corresponding call forwarding operation instruction on your mobile phone: * * 62 * 0201015666 #).

Method 2: If the non-balance is insufficient, it is also necessary to reset the call that cannot be connected and transfer it to the call manager (dial the corresponding call transfer operation instruction directly on the mobile phone: **62*020 10 15666#).
