What is thumb information?

It means that PHS mobile phones (or fixed telephones) supporting PHS intelligent network services can send short messages, pictures and animations to each other. Now, except 700U+ and 700UC of UT, all other PHS phones support thumb short message service. Thank you for your interest in telecom products. I wish you a happy life. If the above information can't solve your problem, you can also log in to Guangdong Telecom Mobile Mall () to ask for help from online customer service, which is available 24 hours a day!
