A Telco That Just Works
GSIM exists because someone had to do mobile properly. No circus. No hidden fees. No shoving overpriced data and extras down your throat. We started out of sheer frustration, the kind you get when your data drops out halfway through an internet argument. So we built a telco that’s simple, solid, and doesn’t treat you like a walking direct debit. We’ve got real service, actual humans, and plans that don’t require a PhD to understand. We’re not here to change your life. Just your reception.
GSIM. It just works. Like it bloody should.


Double the Network
Half the Price
GSIM is one of Australia’s newest mobile providers, launched in mid-2024 from Sydney’s lower north shore. We’re an Aussie-owned MVNO running on the recently expanded TPG/Vodafone network. By using smart tech to keep costs down, we pass the savings straight to you — no hidden catches, just solid service that works well and does exactly what you need it to do.
