If you have been looking for a worthy deal to upgrade your old smartphone this year, look no further. T-Mobile, the disruptive mobile carrier led by the flamboyant John Legere, is saving the day by participating in the upcoming Black Friday sale with full force.

T-Mobile has revealed the list of deals one can fetch during the Black Friday sale starting this weekend. If you have your eyes set on a high-end flagship smartphone, such as the iPhone 7 or Samsung Galaxy S7, T-Mobile is offering a free upgrade to those who trade in their last-gen smartphones – namely iPhone 6s or Samsung Galaxy S6.

The free upgrade program also works for the iPhone 7 Plus if customers trade in their Galaxy S7 Edge or LG V20. Owners of older smartphones can also take advantage of the attractive exchange offer, but they will have to shell out some cash for upgrading to the latest iPhone or Galaxy smartphone.

Take a look at the trade-in offers for an iPhone 7, iPhone 7 Plus, Samsung Galaxy S7 or Galaxy S7 Edge by T-Mobile below. It is worth noting that the trade-in offer is only applicable if the customer chooses either T-Mo's One or Simply Unlimited plans.

Trade-ins aren't the only offers customers must be looking at this coming sale. If you choose to switch numbers, T-Mobile is offering $200 in cash for each line. This is not a credit on your bill, but actual cash added on a prepaid Mastercard, so it can be spent anywhere. Make five such switches, and you are looking at $1,000 in cash.

If that is not exciting enough, T-Mobile is giving everyone a free hour of GoGo in-flight Wi-Fi on domestic U.S. flights. Stay connected even on the air, while traveling anywhere within the States from now till Saturday.

Legere is promising to come up with more deals, so watch out T-Mobile's Twitter space for more.
