There are several ways with which you can go online using your mobile phone. But if you want fast connectivity, 3G or WiFi is your best bet. Using the former will cost you money if you don't have data with your plan, though. So stick to a WiFi mobile so that you can browse the internet for free wherever there is a signal available. There are many mobile brands today that produce WiFi phones. Some great examples are Apple, Blackberry, HTC, LG, Nokia, Motorola, Samsung, and Sony Ericsson. The WiFi handsets offered by these brands range from entry-level to high-end mobiles. In other words, you don't have to buy a very expensive handset in order to enjoy accessing WiFi while you're out and about. In fact, there is a good number of affordable mobile phones right now that come with WiFi connectivity. These cheap phones are offered free on plans that cost only around £10 and £15.
If you want other amazing browsing features to match your WiFi connectivity, though, you may want to pick a mid-range or even a high-end phone. These types of WiFi phones come with Flash support, better browsers, bigger screens, or touchscreen displays with multi-touch support. This means that you will enjoy a better web browsing experience with one of these handsets. For plans on all types of WiFi mobiles, check out 3, O2, Orange, Virgin, Vodafone, and T-Mobile. You don't have to choose a plan with data if your WiFi handset does not have 3G support.
