I noticed this in the paper at £15 /m yesterday so decided to see if my current network would match it. They wouldn't, so I phoned Vodafone (on 0808 0 408 408) for more information and was offered this as a new customer:
- Vodafone SIM @ £10 /m (discounted from £15 /m) (includes 600 x-net anytime minutes and unlimited text messages)
- 12 month contract, upgradable after 9 months
- £5 discount only applicable for 9 months, after which you can upgrade
- I was advised that a similar agreement could then be made
- Free delivery
Now i didn't have to negotiate, it was just offered to me. However, my neighbour did. She stated that one of her friends had been offered this deal earlier in the day, was put on hold, and was then offered the same deal.
If porting your number to Vodafone, this can only be done at the time of agreeing a new contract - online, over the phone or in store. Yes, you guessed it, i had to learn this the hard way...
