What does G mean, and what's the difference between all the networks?

The 'G' in 2G, 3G, 4G, and 5G stands for Generation. It shows which version of mobile network technology your phone is using.

2G: For calls, texts and very basic internet.
3G: Added better mobile internet and email. We are switching off 3G as we prepare to launch our new network.
4G: Faster internet for browsing, streaming and apps.
5G: The newest generation, offering faster speeds and a better internet browsing experience. It will help our island communities stay connected today and ready for future online services.
