Why can't Sony t2' s mobile phone receive Unicom's short message?

Unicom users often fail to receive short messages for the following reasons:

1. You can check whether the mailbox is full first. If it is full, 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;

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 the above problems do not exist, it may be related to the network function. I suggest you contact the local manual customer service to deal with this problem.
