I9508 SMS is unstable, often fails, and MMS cannot be received.

According to your description, I suggest you try the operation according to the following steps:

1. Turn on the data switch on the top curtain of the mobile phone.

2. Open the phone settings-Connect-More-Mobile Network-Access Point Name-Menu-Reset to the default settings.

3. Send a new color message after successful setting (the previous MMS may not be received normally due to network or time problems).

4. Try to replace another SIM card.

5. If you can't send and receive MMS normally, please back up your mobile phone data (phone book, information, multimedia files, etc.). ) and restore the phone to the original settings-privacy-restore the original settings). If the problem still cannot be solved, you need to send your mobile phone to the nearest service center for testing.
