After installing the software and C skin on touch 4, I can make calls and surf the Internet, but why can’t I send text messages?

This is one of the defects of apple skin. Calling or texting can sometimes be unstable. For example, when sending text messages, the following situations may occur:

1. The text message cannot be forwarded

2. The caller’s number cannot be called on the text message interface

3. After sending the text message, the text that has been entered will still remain in the text box

4. Multiple contacts cannot be added at the same time

5. No caller will be displayed for new text messages

6. Cannot view text messages in landscape orientation
