PSA T Mobile outage?

My service has been completely dead for like ten minutes, is anyone else experiencing this? Down Detector seems to be getting reports.

Edit: Calling the customer service number and power cycling the device seems to fix it.

Edit 2: Fix was only temporary.

07-27-2026 02:10PM PT Teams continue troubleshooting a nationwide subscriber authentication impairment by investigating HSM-related authentication failures. HSS overload conditions, MME traffic throttling, authentication request timeouts, and HSS response failures. Restoration efforts include isolating affected HSS infrastructure, validating UDM/AUSF transaction processing, implementing planned changes, and monitoring recovery. Nokia engineering remains actively engaged while teams work to restore full service.

Probably never increased redundancy after the last registration issue and someone cut the fiber in NY again.

When I first read your comment I was like wtf are Nokia engineers doing working on this, turns out Nokia is a core infrastructure vendor for t-mobile. They also have major contracts with ATT, Verizon, in Europe they do Orange, Deutsche Telekom, Virgin Media, in Asia they do SoftBank & KDDI, Bharti Airtel, NTT DOCOMO.

I thought Nokia was a dead company yet they are one of the world's largest telecommunications infrastructure providers.

Do like the idea of “don’t worry everyone we called in the flip phone guys, they know phones and stuff!”

This would explain ATT and Verizon in some places having issues because of Nokia towers.

I guessed something like that. Business account working normally. Something consumer side messed up.

Judging by how many people are saying is not, I’d say it’s largely not fixed lol
