Kev - which way did you go? I have had a couple of contracts with 3 with no problems. In fact the biggest problem has been trying to terminate the contracts - they keep throwing freebees at me! (One I will try cancel again in April they gave me £211 credit as long as I would commit to another 12 months @ £30/month with 9 months half price - effectively £13.50 for the year with 500 free mins a month!)
Seems getting a free modem for this mobile broadband is now almost routine - the 3 website has them for 12 month contracts for either the £15/month (3Gb cap) or £25/month (7Gb cap) flavours.
Does anyone (Toby?) have current/actual speed checks? From what I read the technology is capable of 10Gbit and it is mainly a factor of how fast the guys crank up the networks. (And also the modems: the 'bar of soap' USB thing that Vodafone & 3 are punting has a 3.6 Mbit max.) 3 say their turbo+ does 2.8, seems Vodafone claims the full 3.6 but I passed by some reports that say folks are only getting 700k etc. (A bi like getting 2Mbit from 'up to' 8Mbit ADSL!)
ps
Dumb question, what is '3 mobile broadband'? Is it GPRS, UMTS or HSDPA?
LT - Vodafone & 3 are HSDPA - T-Mobile network shares with 3 (IIRC) and Orange website I find so hostile I am not sure what they really do! Seems the modems like the Huawei bar of soap will utilise whichever of HSDPA, WCDMA, EDGE, GPRS or GSM they are allowed to and can find a signal for.
