I can send some emoji as successfully without any problem but the most emoji can’t be send.
I see the emoji in the playSMS web interface without any problem . In the Reports " All sent messages" I can see the all of the emoji but when send it in the phone that receive the message I receive only question mark ??? one ? per emoji.
Note when I send the emoji via the web interface of the GSM Gateway the emoji send without any problem.
Thank you for your help.
