<human>:  Can you use the T-Mobile tuesdays app if you aren't a T-Mobile customer?
<bot>: No, you can't use the T-Mobile tuesdays app if you aren't a T-Mobile customer. T-Mobile tuesdays is a rewards app for T-Mobile subscribers. T-Mobile Tuesdays verifies users by making sure they have a T-Mobile phone number. So you can't use the app unless you subscribe.
