I am going to the uk in 3 weeks and i am taking my vodafone prepay cellphone with me. while inside the uk i am going to be calling uk cellphone numbers. do i have to dial the uk cellphone numbers with +64 in front of the number or just the uk cellphone number on it's own?
If a person calls my cellphone from new zealand do i have to pay for this because i am roaming or does the person calling pay?
