Vodafone UK (90 day expiry) so be careful, T-mobile and others are 180 days.
Virgin Mobile is 1 year but wont roam without credit agreement signed.
O2 generally does not roam that well.
Vodafone is great worked everywhere i went.
T-mobile 2nd great. I can talk to customer services for free from in china.
costs them :)

Does the Tmobile UK offer of no more than 1 pound a day in GPRS charges translate to prepaid SIMS also? If so, getting the 4p a minute to the US plan and unlimited data for 1 pound seems to be a great deal...I have an unlocked N95, and it should serve pretty well roaming around the UK...

Apparently so; I haven't used gprs myself but have read this several times

And as well as the USA bundle, you can also try the callthrough numbers of Yourcallworld, which has a new agreement with T-mobile about its numbers that allow int'l calls from for 3p a minute. It's not account-based, and not on top of the normal 12p rate to UK, just 3p.

Not that I don't believe you, but why in the world would TMobile undermine their own rates? Just seems odd to me...of course, being a TMobile customer here in the US, I don't see why they just dont offer a world travel SIM, with decent rates, instead of this $1.99/min garbage...
