Unlimited Mobile Broadband

A simple guide to understanding unlimited mobile broadband deals

Avoiding bill shock from exceeding your data limit

Unlimited mobile broadband from T-Mobile for just £10 a month. See this deal...

If you’re looking to use mobile broadband as your main way of accessing the Internet, want to use a lot of data on the go or simply want to guard against bill shock by ensuring you can’t go over your data allowance and run up big bills then unlimited mobile broadband may be just the thing for you. With most mobile broadband deals there is a finite amount of data access included for a monthly fee. As long as you choose the right package for you (see our how much data do I need? guide) this isn’t a problem but if your mobile broadband needs fluctuate and one month you run over the allowance you then start getting charged separately for all the data that you use and with out of bundle data costing anything from around £20 to £100 per gigabyte there’s a risk that you could run up a big bill.

Unlimited mobile broadband guards against this by capping the amount that you will pay at a fixed monthly rate so that you never get charged more than this for using mobile broadband in the UK (there are still roaming charges if you decide to use it abroad). Since Orange withdrew their £35 unlimited deal there is now only oneunlimited mobile broadband packages available in the UK - see below for details.

T-Mobile Unlimited Mobile Broadband
This unlimited mobile broadband deal is from T-Mobile and this is the most popular mobile broadband deal with users of this site and our recommendation as the best mobile broadband dongle deal available. This deal costs £10 with a free dongle and this is all you will ever pay as there is unlimited browsing included. However, the T-Mobile deal does have a clause in the T&Cs that says there is a fair usage amount of 1gb a month for downloads. The terms say that T-Mobile won’t charge you if you go over this amount but they do reserve the right to restrict access if you consistently exceed it. Essentially this is to guard T-Mobile against serious over use from scammers using the dongle for illicit means and if you mostly plan to use your dongle for browsing and email it's unlikely you’ll run into any problems unless you are a very heavy user and even then you won’t get charged extra but may have your access restricted. For almost everyone this is the best unlimited mobile broadband deal and is certainly our pick. See this deal. If the download limit is likely to cause you problems, however, the other possibility is the 15gb a month deal from Three for £15.99 which you can see here.
