Have you tried a Vodafone SIM card in the device, @RegMiles? 

The network device you've got for your caravan is probably network locked, and will only work with a Vodafone SIM card.

Hi @RegMiles @As @Chalkychap says, your router being Vodafone branded is a giveaway that it will only work with Vodafone SIM cards.
