Hoping someone can assist, as either the Vodafone website is not working for me or I am blind and cannot find what I am after.

I am potentially looking at getting a data only SIM card from Vodafone (I have tested a Vodafone connection and can confirm it does what I need it to do) and am looking for data bundles that give a large(ish) pool of data that expire after 3/6/12 months, as opposed to a monthly allowance (say 1GB that expires in 30 days)  OR something like carry over data on 2degrees where I get 1GB every 30 days and any excess rolls/carries over to the next month rather than expiring if not used.

Does Vodafone offer anything like this?

Cheers
