As a Solomon Islander living in Australia with family at home keeping in touch is important, here is the problem my Aussie Sim Card Provider TPG charges $5.47 AUD per minute when I ask them why so much they blame Telekom & The Government. Can somebody tell me if they are lying or not? If true how do we ( Solomon Telecom ) justify this cost. Comparison costs below

Fiji $ 0.3553 AU Cents per minute PNG $1.2927 AU per minute Tonga $ 2.0586 AUD per minute PLEASE HELP ME UNDERSTAND!!
