The problem of signing up for social media apps with a number

[Burak]

Hello, I am a user from Turkey, my first experience. I have a problem. I can't sign up for applications like WhatsApp Telegram with my phone number. I don't know what the area code should be. My phone number starts with 077 and there is no area code called 07. When you enter 7, it accepts it as Russia, but when I enter the remaining digits, it says that I am missing what I should enter, can you help me?

Country code is +44 or 0044

Drop the first zero of your mobile number so enter it as +447
