I’m curious as to whether it’s possible to use the phone number for a service like “JMP.chat” to create an Apple ID under a pseudonym I intend to use this account only to install apps from the App Store and not to utilize any other services, such as iMessage.
Although I don’t currently have an iPhone, I will keep any of the responses in this thread in mind if I do in the future.
I tried today, with vpn on, it said try again later, then i tried vpn off and same thing.
Using a legit second number. 
lets hope someone knows how to do it. 
you don’t require to give a phone number to create a Apple id , just use the itunes app (on windows/mac) to sign up for new apple id just by using an alias email id.
But i am not sure the purpose of creating apple id if not using any apple products.
From experience: yes.
Just tried on windows and it did ask for a phone number. What country did u do it from?
