Unit 14 M2




The main difference between 3G and WiFi is the speed and signal strength, WiFi is usually a lot faster and therefor is easier to access the internet and emails although the further you are away form the WiFi connection there is more of a chance of 3g should be used, 3g is also good as it is good as you never loose signal but it is a lot slower. There is also a variation in cost 3g cost 80p from Vodafone obviously it can vary but this is a standard cost where as Wi-Fi is free to send picture messages which is a significant advantage.
