Just changed to 4G on EE. Was on an 18 month 3G contract with 750MB download limit as i upgraded to this with a Galaxy S3 last month. They asked me if I wanted 4G then, but the coverage was not the best in my area at that time. They are now rolling it out in my area so it now covers my home postcode and will cover my work shortly.
I got a call last week asking if I wanted to upgrade so asked how much and what i get. I would get unlimited texts and calls, 3GB download limit, bt open zone acess, free music downloads etc etc. This was a 24 month contract but as I had signed up to 18 month they would honour that and also my half price line rental for life so it would only cost me an extra £3 a month. I get all that for £27 inclusive PM
I have checked the speed and currently getting 15mbps on speedtest with a 2 bar signal so should be miles quicker when it is fully rolled out in this area. The lad that rang me said he managed to get 40mbps in Sunderland!
I will see how it goes but for an extra £3pm I cant go too wrong
