4G stands for the 4th generation of mobile technology. A 4G connection will give improved speed when you access the web. This means that pages will load faster and videos will need less buffering. This is also referred to as LTE (long-term evolution). This is the standard for high speed wireless communications.

The main difference between 3G and 4G is speed. 4G is usually 5 times faster than 3G.

We are offering 4G to all our customers at no extra cost however you will need to check whether your SIM and handset are 4G enabled as well as checking the 4G coverage in your area.
