With Vodafone Pay as you go 1, you’ll only ever pay for what you use so, if for example, you make 40p worth of calls on any one day, you’ll only be charged 40p for those calls.
Before reaching your £1 spend cap, it’s 20p a minute for calls, 20p for texts and 20p for each 5MB of data. If you don’t use your phone, you won’t be charged, but please note that you could incur some minimal data charges if any applications on your phone “chatter” and use data.
Chattering can occur when applications you have downloaded update automatically or receive or send data. The only way to avoid your phone chattering is to disable the mobile data on your phone in ‘settings’.
