T-Mobile’s getting ready to kick off the UNcarrier approach this weekend and to make sure all their employees are up to speed will continue training their employees this Sunday. Depending on the store location, hours will vary for extra training including some stores closing mid-day as pictured, opening later or closing early. In any event, T-Mobile’s gearing up for something big with UNcarrier and thankfully we’ve got some pretty good indicators about what’s coming. If you’re planning on making a trip to your local T-Mobile store this Sunday, phone first and check their hours.
