How We Keep Prices This Low
It’s not a gimmick. Plenty of providers advertise a teaser rate and leave the rest for your first bill. We publish the full fee schedule instead, including the charges that only apply in specific situations.
Low published rates for every service, with your exact price confirmed before you book. Additional charges apply only in specific situations, like a late payment or a damaged device, and every one of them is listed above so you know what to expect. That’s the whole model.
