Vodafone launched a pay as you go USB modem that doesn't need topping up every month. It costs £39 upfront and comes with £15 worth of credit, which amounts to 1GB of data. According to Vodafone, 1GB of data lets you do 30 hours of Web surfing, or send 650 emails, or download 65 music tracks or short video clips.
Unlike certain other pay as you go mobile broadband services, the 1GB will not expire after 30 days. The minimum you can top up the dongle each time is £15, which can be done using a voucher or over the phone.
It is capable of speeds of up to 3.6Mbps, but customers should only expect speeds of up to 1Mbps to 2Mbps. The modem will also double as a 4GB USB memory stick.
I would like to refer to this as true pay as you go plan because the topup does not expire after a month. On the other hand, a similar amount on '3' would get you 3GB of data in their version of PAYG which expires after a month.
