4. What are the charges?

  • On your overseas country SIM card, you pay for incoming local call charges if any.
  • To Hoiio, you pay for the callback charges from the country you are in, to the country you are calling to.
    As our callback charges displayed on our websites assume you are in your home country, you may need to calculate the rate for this special case manually. Charges are:
    (internet call cost to country you are in) + (internet call cost to country you are calling to)

If you are unsure

  • Please use just the internet call with the WiFi you can get when you are overseas.
