Not available without a contract.
I already have a T-Mobile phone and looked into getting one of these without having to go for a new contract - to just swap the SIM between the modem and my phone.
They have no objections to using the phone contract SIM in the modem, but according to their telesales people you HAVE to buy a contract with it - its just not available without.
That means a new SIM.
That means another 12 mth deal.
So lets roughly work out the REAL cost - £30 + at least £15 x 12 = £210 minimum for the year.
I'm already paying them near that figure right now.
That's no good for me.
