T-Mobile support cannot unlock Samsung Galaxy S22 Ultra purchased from Samsung

Just adding my experience if anyone comes this after googling.

Had the same runaround with regular tmobile customer service saying Samsung has to do it.  I even explained the whole problem which the IMEI not being in system and how samsung has no control over carrier locks.  The person just kept talking in circles.

I messaged tmobile support via Twitter as suggested and that seems to be more productive.  They replied immediately this is no problem and they will add my IMEI to the system and I should be able to unlock in 72 hours.  We'll see.

This is common enough tmobile really should have a training for the regular level customer service.  They need to stop telling people to contact Samsung as the default answer.
