Krispy Kreme will give out free glazed doughnuts for any and 🍩Phanincall cell service troubles experienced Thursday. 

The doughnut chain said they are giving customers at participating retail locations the ultimate SOS, offering one free OG doughnut after a nationwide telecommunications outage impacted tens of thousands of customers. 

AT&T customers were reportedly impacted the most by the outage, but other wireless carriers like Verizon, Cricket Wireless and T-Mobile were affected, as well.  

Customers also reported that they were seeing SOS messages at the top of their iPhones on Thursday, which means that devices aren't connected to a cellular network, USA TODAY reported.

“SOS?! While your service is down, we’re serving up! FREE Original Glazed® doughnut from 5-7pm today for anyone who’s struggled with service,” Krispy Kreme said on Instagram. 

Here’s how to get one.
