Mobile phone can't send MMS! I keep sending it, but I just can't send it out! What should we do?

The reason why the mobile phone can't send MMS:

1. Check whether the mobile phone supports MMS function;

2. Check whether the parameters of the mobile phone MMS are correct;

3. I suggest you turn off your mobile phone and test it with another one;

4. Check whether the size of the sent MMS is controlled within 50K;

5. Check whether the MMS outbox and inbox are full;

In addition to the above simple troubleshooting, it can't be solved. You can contact the manual customer service for processing.
