What if Xiaomi 2a can't receive MMS and send it?

1, open "Settings" in your mobile phone, find "Mobile Network", enter the mobile network settings, and you can set up the network.

2. Always accept MMS when it is turned on, and still accept MMS when data is disabled, which may result in data traffic charges. MMS is usually opened and often received, which is also the reason why MMS cannot be accepted.
