Calling to Zimbabwe with Hello Mobile

<p>Absolutely horrible! I was using my Hello Mobile SIM card to make calls to Zimbabwe. The call quality is extremely poor.</p> <p>I then arranged with my family in Zimbabwe that I will give them a "Miss Call", so that they can phone me back. That did not work because when I give them a "Miss Call", they get a foreign number on their phones so they never knew that it was me calling.</p>
