5. HTC U11
IM Score: 11
HTC has really outdone themselves with U11 the next one on our list of best smartphones with Nano SIM card slots. Let’s first cover the specs. It has 5.5 inches display, Octa-core processor, 4GB of RAM and 64GB of storage. If this is not enough, there is a version with 6GB of RAM and 128GB of storage. The reviews say its 12MP rear and 16MP front cameras are something special. One thing that also sounds cool is Edge Sense. Basically, the edges of the smartphone are sensitive and when pressed can perform various actions. For some reason, HTC also decided to remove 3.5mm headphone jack from U11.
