We have a number of users with iPhones and iPads. We are with Vodafone and had the users' iPhone accounts updated to have the hotspot bit added. Unfortunately this hasn't been working well with our users who have had trouble using the hotspot and simultaneously taking calls.
What is the best solution for us to be able to provide a hotspot to the iPads? Should we be looking at a small portable 3g Modem? We are based in the UK but travel to Europe as well.
