Hi @lynne41690 Some numbers are always charged to your credit balance as they are not included in your goodybag's minutes/texts allowances (eg premium numbers such as 0845, 0871, international numbers, short 5/6 digit numbers, MMS).
Please look here for more details on which numbers are free, included in goodybags, and not included in goodybags: http://community.giffgaff.com/t5/Learning-and-giffgaffer-articles/Inclusive-and-non-inclusive-calls-...
Even though you may be connected to your home wifi, if you have mobile data enabled and your wifi drops, even for a second, your phone will use mobile data.
If you have an iphone, wifi assist will over ride your data settings even if mobile data is OFF, ensure wifi assist is OFF
Couldn't be cause I'm currently connected to Internet at home..??
