I've been looking into join airdrops recently and it seems that many of the require telegram. I'd like to know if anyone has found workarounds for how to bypass handing over your telephone number in order to make an account on telegram. This is annoying since so many airdrops seems to require it.
There's actually an app called 2nd Line which gives you a dummy number you can use to sign up to Telegram...but like other posters already said there's no way for the people on Telegram to see your number, they only see your user name.
