Make sure you understand the difference between 2G and 3G signal
, though. While 2G is readily available everywhere and allows you to do the basic phone stuff like calls and texts, 3G isn't always as easy to find but can do a lot more including accessing emails and the internet. When looking at signal range guides or doing postcode searches, make sure that you look at both 2G and 3G signal for a better overall view of what you can expect from your network.
