Why can't Nokia C7 open SMS?

You turn it off and try. I'm also using c7. Take me as an example. After I open the short message, there is a short message icon, but I am not a multimedia message, but an ordinary short message. When I opened it, there was a small icon. Then I shut down and restarted, and it was gone. I don't know what your specific situation is.

You can try to restore the appearance settings to see if they are available, or you can turn them off and then on like me to see if you can turn them on. No, if you receive MMS, you can't turn it on. Maybe the mobile phone system may be stuck.

Set up SMS. Click the options in SMS to set MMS, SMS, advertising information, etc. You can turn them off and see what happens. If not, you can only go to Nokia customer service.

hope this helps
