SMS prompts that the storage is full. How to change the storage location of SMS from sim card to mobile phone?

The default storage location of SMS is mobile phone, so it cannot be automatically saved to SIM card. If your mobile phone has an abnormal situation that every message is saved to the SIM card:

You can use

EMUI4。 X: SMS > Menu > Settings;

EMUI5。 X & amp8.x: SMS > More > Settings;

EMUI9.0: SMS > three points in the upper right corner > Settings > three points in the upper right corner, and then click Restore Default Settings below to restore the default settings.

Alternatively, you can try deleting data to recover:

EMUI4。 X & ampEMUI5。 X: settings > application management > information > storage > deleted data.

EMUI8。 X: settings > applications and notifications > application management > information > storage > deleted data.

EMUI9.0: Settings > Applications > Application Management > Information > Storage > Deleted Data.

If it still can't be solved, I suggest you back up your data and restore the factory settings.
