The T Mobile 6MONTHWEB was never Unlimited Data, it was Unlimited Web Browsing, it included a 500Mb Data Download FUP per Month (hence why you where told 3Gb for 6 Months), once you hit your monthly 500Mb in any month you were then restricted to Web Browsing only and Download including Streaming was then blocked untill your Monthly Refresh Date, there was an easy work around to this, but I won't bother going into detail as its all done and dusted now.
Originally the 6MONTHWEB was £20, great value IMHO, but was increased to £40 to include UK and EU Roaming, still good value, there were also MONTHWEB (30 Days £5), WEEKWEB (5 Days £2.50) and WEB or what ever it was called (1 Day £1), strangely the 1 Day Web did include All You Can Eat Data (Unlimited) but it was also Speed Restricted to the Original 3G Spec Speeds, 44kBs throughput from memory which equated to around 0.35 Mbs Spped in today's money.
Another good one was OrangeWorld, which was a £1 for Unlimited Data for 24 Hours, but the Hours would start at midnight before you sent the Activation Text, so if you were in the know, you could text at 1 minute past Midnight then get 2 Days of Free Data Usage (47 hours and 59 Mins before it expires).
The best one in my book was the Virgin PAYG Sims, which used the T Mobile Network, as long as you had more than £5 Credit Left, or you could Top Up another Fiver then text the Unlimited Data Add On, which would give you 2048Gbs (yes 2 TBs of UL Data for a Month) but the bit I could never work out was they would refund the £5 after 24 Hours to use against your Calls and Texts, so effectively it was Free?, they did however comedown on you hard if they found you was Tethering or using the Sim in a Router / WiFi.
