looking for a payg dongle data card and found one or two on fleabay but..... Vodafone data only sim with 1gb data and £15 credit, no expiry....£9.99. this is ideal for me as there is no expiry on the data and i dont use the dongle unless out in the van or AOL home B/B goes down. i assume when i top up with another £15 i get 1gb data allowance ? how long could i expect the 1gb to last using it for browsing only...no music or video downloads...mainly for forums and the occasional via michelin route finding. looked for the free 3 and orange cards (no expiry) but cant seem to find any. cheers.
