Not everyone on the planet needs to have a phone on them 24/7 - and I am one of those who have never felt the need of one. 
But I cannot communicate with anyone in this community on Discord, because I DON'T HAVE A MOBILE PHONE!!!!!

discord works on computer as well i believe you are confused. discord was created for computer in the first place cause it was made for gamers doesnt make sense for it to only be for phone, create an account and click on the discord link
