T-Mobile Samsung S21 series $499.99 + extra trade-in value
T-Mobile one time payment savings for new and existing customers. If you're a new customer, I recommend looking at the other thread for the unlocked device, I believe that is $399 after activation for new, especially if you don't have a device to trade in.


S21 - $499.99 ($300 savings)

This stacks with the extra trade in bump of $150-$200 from Best Buy. This discount comes right off the price of the phone vs. bill credits.

Traded in iPhone 8 64 GB for $230 off $499, total was $269 plus tax

S21 - https://www.bestbuy.com/site/sams.../6464393.p


Instructions on how to get the deal -
Quote :
After clicking the link, click the $499.99 (Activate Today) button
Click Add to Cart
Select Upgrade if you're an existing customer
You'll be greeted with the following question "Would you like to trade in a phone?"
Select "Yes, I would like to trade in a phone to Best Buy."
Fill in the 5 required areas (Brand, Model, Capacity, Color, Carrier)

From the prior deal last month when the device was $599, here was what was shared. I did a quick check and confirmed the Galaxy S20 trade in value was still $410. I imagine there may be some discrepancies since the iPhone 8 was $230 for me instead of $245.

$399 offer should still be better considering you can cancel the plan same day. It's just a little extra work and worry.

It doesn't stack with the trade in promotion, otherwise yes. Trade in value for iPhone 8 at 64 GB would only be $80 for unlocked S21 vs $230 for T-Mobile S21

What device are you attempting to trade in? I noticed it is a bit weird, I tested the trade in value of a iPhone 6S at 64 GB and received a $180 quote, but 256 GB had a lower trade in value. Was really odd.

I've looked for the answer to this but what are the disadvantages of using unlocked vs T-Mobile? My simple choice plan has slower international data and unlimited texting included so will non T-Mobile phone work for this?

Tried to trade in my TMO Blue S20 FE. T-Mobile is not on the carrier list.

I have another S20 that is still on TMO EPP. This one can not be traded in without the balance becoming due. Correct?
