Got myself blocked from Twitter - won't accept my phone number [View all]

So I sent a hastily considered tweet to someone asking "What should Putin do now?". My response got me blocked for violating their TOS against talks about suicide. Mea culpa.

To get back on, they are asking for my phone number. I use Republic Wireless which is a VOIP/cell hybrid. I am being required to get a new phone by March 31 because of the switch to 5G.

If I go ahead and order the new phone with 5G, but it keeps my old phone number, will I still be blocked? Had a similar problem joining a Discord with my phone, but they manually allowed me in.

Suggestions? Thanks in advance.
