Has anyone here succesffully enabled Teams SMS with a requested number pool in GCC?

We have a GCC tenant using Teams voice and would like to enable SMS. We've gotten both our brand and campaign approved, but our number pool request has been pending for months. Microsoft support isn't helping and our Microsoft rep says it's not available in GCC despite being able to apply and get approved. I reached out to TCR and they said it's T-Mobile's (what?) problem. Has anyone here gotten Teams SMS to work in a GCC tenant using 50+ numbers?
