Help, why can't I receive the Japanese version of Z 1 Unicom service SMS?

1. If you can't receive it, you can check whether the mailbox is full first. If yes, please delete some information.

2. If it is still not received after deletion, you can change the machine or card to see if it is a hardware factor;

3. After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

If none of the above problems exist, it may be related to the network function, please contact the local manual customer service to deal with this problem.
