I have a year old unopened Vodafone SIM card. Can I pop that into my Mifi and sign up to Smart19 Data? It's not too bad for 500MB. If I need more I can go Freebee Data and get 1GB for $40, or go to Telecom and get 2GB for $50 (assuming they use a standard SIM).
Can the sign up all be done online? The MiFi can't send or receive txts, or make calls.
