Oh no! Super bummer!
Can you try rebooting the phone and searching for T-Mobile by doing a Manual network selection? I'd also like to know if it's only happening at the office or if it's not getting signal in other areas. Please keep us posted. Thanks!
Hey there! Are you still having trouble getting signal at work?
Good morning, philb!
I just wanted to swing by one last time to check-in. Are you still having issues with your S8+ picking up a signal at work? If so, please give the steps that Mike mentioned above a shot and let us know if that works.
