First released via Metro by T-Mobile (not long ago), the LG K40 is not as cheap as the Aristo 4+. The phone is priced at $206.25 outright, or $8.25 down plus $8.25 per month over 24 months.

You're paying extra for the K40 because this handset features 3D surround sound, an octa-core Qualcomm Snapdragon 450 processor (which is slightly superior to the Snapdragon 425 that's powering the Aristo 4+), and 32 GB of expandable storage space. The LG K40 also sports a larger, 5.7-inch display, although its resolution is of only 720 x 1280 pixels. Most of the other features of the K40 are on par with those of the Aristo 4+.
