Very large smartphones have a large screen or a relatively small screen and large bezels. These phones are generally about 7.5cm wide and up to 16.5cm long. Even though a large screen is nice when you often watch movies and series, phones of this size are difficult to control with 1 hand. It also doesn't fit in your pocket. When you buy a smartphone, you can use it with a phone plan from any provider. All smartphones at Coolblue are SIM free.
