Joke Collection Website - Public benefit messages - I used Unicom's card. I sent several MMS messages in a row, and suddenly I couldn't send any more colorful letters. Text messages are normal. What happened?

There may be two reasons why MMS cannot be used on mobile phones:

1. The mobile phone does not support the MMS function, so your mobile phone will not be able to send or receive MMS messages. You can log in to the MMS mailbox of Unicom website to check the MMS sent to you.

2. There is no Internet access function. You need to access the Internet before you can send or receive MMS.
