I figured it out!!!
For the first problem, I creat another ID apple and I only use it on the imessage.
For the second problem, I had some contacts with the full number +971 (0) 5******** I don't know why I put it that way, so I just eliminate the (0) or eliminate the prefix +971 (it depends on your country) and maintain the zero, and now I can change imessage or text message with everyone.
