They want to send a text to my flip phone, which doesn’t receive texts, when it clearly said they’d send it to the “same device” I was using to create the account. This is the same wall I hit last time tried to create an account. Someone there doesn’t know how to send simple email. DJT’s webmaster could fix it if he knew. the problem.
Which leads one to wonder if and how many subversives in the organization are sabotaging it.
It's fairly easy (and free) for an individual to set up hundreds of unique email addresses. However, it's very cost prohibitive to purchase a lot of cell phone lines. This is one of the reasons why Truth Social wants to tie your account to a unique cellphone number.
It stinks for people like you who only have a flip-phone but I cut Truth some slack here because they have a lot of enemies that want to shut them down or otherwise prevent them from becoming successful.
I know there are techie workaround for this, such as using a VPN and extracting the verification code out of HTML code (that is linked to your flip phone number) but I'm thinking because you have a flip phone to begin with, this is probably not something you would have the skills for (this is beyond my skill level as well).
Hopefully Truth Social can do a workaround for people in your situation. You might want to try emailing their support team at support@truthsocial.com.
Good luck.
