4. Apple iPhone 7+
IM Score: 12
Although you would think this entry on our list of best smartphones with Nano SIM card slots is a just bigger version of iPhone 7, there are some differences. While they both have the same processors and storage capacity options ranging from 32GB to 256GB, iPhone 7+ has 3GB of RAM. There is also a difference in the rear 12MP camera since iPhone 7+ has a better version with dual lenses. The battery life is better, but it still doesn’t justify the price. This Apple’s smartphone is the most expensive one in the company’s history.
