So will these cards call Philippine mobiles at the same rate?
I guess some will but always remember that from a UK mobile 0800, 0845 and a few other access numbers are not free from a UK cellphone so your card call might be cheap but you can also be paying your mobile provider at the same time!
They are all VOIP services i.e voice over internet protocol services, same as Skype, does sound cheaper than Skype though so I need to try it and see what the voice quality is like.
Skype txt 3.5p + VAT, return message from the phils 20 peso (usually) :(
