My mobile phone is Sony Z2 and I use China Unicom 3G card. Why is there a delay of about 10 minutes in sending and receiving text messages?

The delay in sending and receiving text messages on Sony mobile phones may be due to the following reasons:

1. The network system is busy, it is recommended that you try again at another time;

2. Due to the mobile phone, you can Restart the phone or change the phone to test;

3. Shut down the phone for a long time or not in the service area;

4. The SMS inbox and outbox are full, you can clean them and try again .

5. The mobile phone is shut down. It is recommended to pay the fee and turn it on again to try again.

If the above reasons are still not resolved, please contact 10010 manual customer service for processing.
