If you are a heavy data user you may want to consider a SIM only unlimited data and internet plan so you never have to worry about going over your data allowance. If you go over your data limit the additional data is charged at a relatively high rate by most UK networks compared to the quota of data included in your deal. To work out if you need an unlimited data plan take a look at your recent bills and take the average data usage from the last 3 months. If you don’t have access to your recent bills the BBC has a good article on working out your mobile data use. Compare this to plans which have a set amount of data and if none appeal or have sufficient data limits then consider a deal which does not cap your data use. If you want a plan for your tablet, with no minutes or texts there is a range of data only plans. There are also plans available which have unlimited texts and minutes in addition to internet so you are not capped on any aspect of your mobile use. Not all UK mobile providers offer SIM only plans with unlimited data; we compare plans from Three, Vodafone, O2, T-Mobile, Orange, EE and Virgin.
4G is much faster than 3G internet, if you use lots of data then you may want to consider a 4G plan so your internet use is not stifled by slow speeds. There is a range of 3G and 4G unlimited data plans available, however it is important to check you can get 3G or 4G coverage levels in the areas where you are likely to be using your mobile or tablet or you may find yourself paying for something you cannot use. Thankfully most UK network providers have coverage checkers on their websites so you can check before making a purchase. You can compare 4G SIM only plans here and 3G plans here.
