Kawara Tsutomu, why can't I send messages by SMS? Display failed to send.

Are you sure that the SMS application has been completely installed in Kawara Tsutomu? Is there any cell phone off? Not long ago, I also installed Kawara Tsutomu SMS and downloaded Kawara Tsutomu doll font and magic pill skin, all of which can be used. By the way, it is better to download the SMS installation package from Kawara Tsutomu to the official website Kawara Tsutomu, which is more reliable. There are three Kawara Tsutomu SMS programs on the official website. Maybe what you downloaded doesn't match your mobile phone.
