Phone Verification & accessibility issues

I live in an area that has no service which is not uncommon in the UK given how rural we are. I literally can't receive SMS right now and as a disabled person that is clinically vulnerable, I am still not able to safely venture out despite easing of lockdown due to complex medical reasons.

Phone verification, therefore, poses a barrier to access for me as a disabled person.

I have been in contact with DISCORD directly even sending them screenshots of my phone showing no service but they refuse to accommodate my circumstances or disabilities. I feel this is exclusionary and doesn't provide alternative access to people in my position.

There is also the matter of data consent when an alternative is not provided which I feel is a breach of GDPR here in the UK that despite no longer being part of the EU is still a legal requirement since it's still on our statute books.

Why I am not being offered an email verification alternative everything I have relayed to DISCORD is beyond me.

Barriers to their own platform seems counterintuitive to me and a poor business model. Please address this DISCORD!
