How to open the file received by SMS if it is not the original file?

If the MMS cannot be opened, we suggest you try the following:

1. Check whether the mobile data is turned on (standby screen-pull down the top curtain-data is turned on).

2. Settings-Wireless and Network (More Networks)-Mobile Network-Access Point Name-Menu-Reset to Default Settings

3. Check whether the attachment is too big and the memory is enough.

4. Back up data (contacts, text messages, pictures, etc.). ) and restore the factory settings (Settings-Reset/Privacy/Personal-Restore Factory Settings).

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local after-sales service center for professional engineers to help you test.
