Whats difference between mobile phones with wifi and mobiles with unlimited internet and e-mail access no wifi?
Wi-Fi is a short range, but fast wireless networking system. You need a third party Wi-Fi supplier in most cases (often this will be yourself – but connecting a wireless router to your existing home broadband, so you can use Wi-Fi at home). The alternative is 3G, Edge, GPRS or some other cellular data scheme. This is slower, but much longer range – as it uses the same system as mobile phones do for voice calls. If you have unlimited access then you won’t be charged additional fees for cellular data transfer.
