Check out these cool new iPhone SE (2020) deals at Boost and Metro by T-Mobile

It's therefore needless to say that we were quite surprised to see the modernized 4.7-inch handset with a traditional Touch ID fingerprint sensor discounted right off the bat by several different carriers and major retailers. Even Apple itself seems unusually generous, offering massive savings with eligible trade-ins including everything from the iPhone XS (of course) to the iPhone 7 (nice).

The only inconvenience is, well, that you'll actually have to use the new iPhone SE on a fairly unpopular carrier. Still owned by Sprint, Boost is expected to move under Dish's supervision soon as a T-Mobile MVNO (mobile virtual network operator). That basically means you'll get access to Magenta's continuously improving 4G LTE network, not to mention Boost's prepaid plans are quite competitive, currently starting at $50 per line with the "Unlimited Gigs" option.
Technically, the diminutive phone with huge screen bezels is even cheaper at Metro by T-Mobile, starting at $199.99, but to score that massive $200 discount, you'll need to port in an existing number from a different carrier (other than T-Mo, of course.)

Network switchers will get an instant $200 rebate off the aforementioned $400 MSRP, but another important thing you have to keep in mind before pulling the trigger is that this deal is exclusively available in physical Metro stores, and a new phone doesn't exactly qualify as an "essential" purchase worth risking your life for.
