4G is the 4th generation of mobile network technology, giving you faster speeds and an overall better internet experience. You’ll definitely notice a difference when you’re gaming, streaming, downloading and surfing. It’s fast.
4G is a data-only network. That means that when you make or receive a call, your service needs to drop from 4G onto either 3G, or 2G networks. When you make or receive a call, you'll notice the '4G' or 'LTE' symbol on your screen will switch to a G/GPRS; E/ EDGE, 3G; 3,5G/H ან H+ symbol. When you finish your call, your service will try to reconnect back onto 4G LTE.
