If you are looking to purchase a dongle for internet access on the move it is a good idea to ensure that you compare mobile broadband packages. All providers have varying mobile broadband deals and the speeds, prices and download limits vary greatly. If you are planning to opt for a mobile broadband contract these are generally available for 12, 18 or 24 months and you can expect to pay between £10 and £30 per month. However, as with mobile phones you can also opt to purchase a pay as you go dongle that you top up as required, however you do have to purchase the dongle up front which can cost in the region of £60. You will find that most of the networks operate a fair use policy for download limits.
The mobile broadband comparison is necessary as all of the networks have options to suit every budget. For example, Vodafone offer their Ultimate Plan on a 24 months contract. You can expect to achieve speeds up to 7.2Mb and you can download up to 5Gb per month. On this contract the first three months are as low as £10 rising to £25. However, at the other end of the spectrum Vodafone have a standard option with free dongle for 3Gb usage per month at the cost of just £15.
However, it is worth noting that no matter which network you opt for that you should check coverage in your area to ensure that a service is available.
