Supposedly (is that a word) the Vodefone CSR should tell you when they think it will be ported. All the information is here http://bit.ly/bdlgf9 but it doesn't actually have a specfic answer to your question. I'd get on the phone.
*EDIT* Duh thanks for pointing out that on the actual link I provided the answer was there ;) (See below)
semigeek: All working now, but one more question. I'm now on Starter 600, but if I login to My Vodafone, or dial 777. It says I only have 19 sms. But there are 600 any network texts in the plan. Why is this?
First invoice is prorated so your bill cycle date will be soon remember the first invoice will have part months charges and then one month in advance for the plan / services
