I can't send text messages.

Hi !

I just recently change my Sony Xperia XA screen, because I broke it. It appears that the tech guy who changed it to me reboot completly the phone, as I lost everything on it. Now the screen is new, the phone's working really well. 

My only problem is that I can't send text. I can type the text, add the contact i want to send it to, but when I want to type on the arrow to send the text I can't. The arrow is grey, like it's lock or something like that, like there's nothing on the text, no words or contact. I join a picture so you wan see. 

Did someone had the same problem ? Because it's a bit problematic, as the rest of the phone's working really well. 

Thanks !

@Lilouytouhave you inserted the SIM card after getting the phone back? because there's a "no SIM" icon on your screenshot (between the WiFi icon and 70%)
