It can connect to a WiFI network at no extra charge. However, she will need to be in range of a WiFI hotspot. If she has a wireless router or access point in her home, then it will be able to connect to this. (Just like a laptop can) She will also be able to use WiFI facilities in airports and cafes etc.
There's also another communications technology known as 3G
. Essentially, this allows you to connect to a mobile phone network and send/receive data that way. I believe the iPad with 3G
functionality is sold at a higher price. You will also need a special sim card in order to use this service. Obviously 3G
provides greater coverage than that of WiFI but you will need to check with the provider for further information with regards to coverage.
In summary, both will provide wireless functionality. But to clarify further:
Great for connecting to the internet while at home, (no extra charge other than what you pay for broadband/cable) or at some cafes and airports. (often a service charge)
Great for connecting to the internet while out and about, whether it be on a train, in a supermarket or on a roller coaster. (ok, perhaps not) There's usually either a monthly subscription or pay as you go charge for this service. Most service plans typically include a data cap too. (a limit on how much you can download without having to pay extra)
