I sent a text message to my friend in Turkey. What should I do if he can't get it?

My friend, your method is wrong. You should send it like this, 0090 with his mobile phone number instead of 4 12, and don't add 0 before his mobile phone number. For example, your friend's mobile phone number in Turkey is 0535 598778 1, so if you want to send him a text message, you should send it like this. After editing the message, the recipient should write 090538. There is something wrong with the way you sent it. I hope I can help you. I told you, he can receive it 100%. I wish you success!
