Can I get Vodafone's always connected data on a Vodem / 4G (or even 3G) data stick? I already have a mobile with an eligible plan, it would just be more convenient not to have to re-route everything via a phone then change it all back again a few hours later.
Ideally, I'm looking for a zero/minimal monthly cost plan, since this is just a backup for outages, it's not intended for primary usage. I can spring for the data stick itself.
