The OnePlus 7T is a great choice for those who need a good, moddable phone in a pinch. And if that pinch is happening right now, you're in luck: B&H Photo has the device at its lowest price yet!
Standing aside from the rat race of specs, the 7T holds up extremely well on paper: three rear cameras with a 48MP lead sensor, 128GB of storage, 30W charging, in-display fingerprint sensor, and the Snapdragon 855+ chipset. No 5G to speak of, but Android 11 is on the way, so if you're looking to fill a gap, you won't be out of place much here.
Keep in mind that this is the T-Mobile variant and that the phone was out prior to the carrier's merger with Sprint. You'll find the best cellular compatibility on its home network, some on AT&T, and practically none elsewhere.
