hello,
Yes. You may not want to if you are happy with your ISP provider though. Remember quality of customer care, technological support and speeds vary. However, many companies offer special deals to get you on board and take you away from competitors. So it is definitely worth keeping a look out for the opportunity of taking advantage of any special offers on the market, which could offer good savings and improved services. Always check your contract first though as you will have to fulfil the minimum contract criteria with your current ISP first.
