Why can't I send Fetion SMS on my mobile phone?

If your mobile phone can use the SMS function normally, sending and receiving is not a problem.

You can reply directly to the short messages of Fetion friends.

If not, try it. Can I send text messages to other numbers normally?

If you can, you can't send a fetion to your friends, which means you haven't enabled the fetion function yet.

And you can go to the nearest local business hall for consultation or handling.
