T-Mobile Says Device Carrier locked

This sounds oddly similar to

No Mobile Data on Mint

@plamen yes, they both start with 3500216. Here’s the weird thing. I activated this phone on Monday, had no mobile data. Mint support tells me I’m locked. Continued to have no mobile data through Tuesday. Turn the phone on Wednesday morning and I have data now. I didn’t change anything on my end to get things working.

The topic includes feedback from another customer reporting the same.

We’ve escalated this matter to GSMS - the association that manages device identification (IMEI), which is what telcos use to determine status of a device (locked/unlocked, stolen, etc.).
We’re still waiting on feedback from GSMA.
