They ask me to verify my phone number, but when I try to do that, I get this message that "this carrier is currently not supported". And there's no option to change my phone number.
Is there any hope of getting it back?
As my educational presence has grown online, I've had several ideas for things I'd like to teach or build that involve Twitter's API, but I can't join their dev program without a number and they don't accept the one I have. Given you lost your whole account over it, maybe I'm lucky I haven't been able to link a number.
The entire idea of requiring a legacy phone number to use online apps is both a huge step backwards and exclusionary towards anyone who doesn't have a stable number due to frequent travel or other reasons.
