I already own a blackberry device. Can anyone recommend a SIM only subscription in the UK that I can use with my device?
Thanks,
Mark

T-Mob do a basic 7.50 per month sim only deal (about 50 minutes talk time) with £10 extra for Instant E-mail - however taking the e-mail plan on top means you lock yourself to a 12 month contract.

Not sure about the other networks - am sure that 02 and vodafone would do something similar, however from my experience if you are using it primarily for non-work functions then T-Mobile are the better option.
