the free 30 day data pack has ran out on my R207, I have bought a £15 top up voucher to get a new data pack but from what I can make out I have to register wi my Vodafone to do this. The problem is that I can't connect the R207 to the Internet to get the security code that should be sent for me to register. So how do I get my R207 topped up with the voucher and what data pack do I buy ( I was going to get the £15 4G but from what I've read on here that won't work. I will be running two iPads off the R207 ).
