如果你是号码被BAN就这样写
Hello telegram team
My number is banded.
Please unban my number. thank you so much telegram team

如果你是号码被BAN后又自动恢复登录了,但是你的手机号收不到验证码了,或者说是号用不了了,就这样写
Hello telegram team
My mobile number was banned before, Now is unband,But I can’t receive the mobile phone verification code, because that number can’t be used, I haven’t changed that number, it can be used before, but after banned, all clients are forced to quit
Please Help. thank you so much telegram team
当然,第二种情况恢复的机率就非常低了
