Open Recommended Guide / Stock →Why do Facebook Marketplace & Gumtree phones get blocked ("SOS Only") weeks after buying?
Private sellers often sell phones still under 36-month Telstra/Optus/Vodafone finance and later stop paying or lodge an insurance claim, triggering a nationwide AMTA IMEI blacklist. PRC (#2PS2914401) backs every phone with AMTA verification and a Lifetime Clean-Title Guarantee.
Open Recommended Guide / Stock →iPhone 17 vs iPhone 16 Pro vs iPhone 15 Pro: which is the smartest outright buy?
Certified iPhone 16 Pro and iPhone 15 Pro give you 120Hz ProMotion Always-On OLED, titanium frames, 3x/5x optical telephoto zoom, USB 3 10Gbps data, and Apple Intelligence AI for hundreds less than brand-new retail RRP.
Open Recommended Guide / Stock →How do I avoid Kogan, Dick Smith, or marketplace grey imports (LL/A, CH/A, J/A)?
US LL/A iPhones lack a physical SIM tray, China CH/A lacks eSIM, and offshore imports risk post-3G 4G VoLTE Triple Zero (000) blocks. Every PRC phone is verified at 122 Queen St, St Marys for Australian ACMA RCM and 4G VoLTE 000.
Open Recommended Guide / Stock →What is the best unlocked phone under $300, $500, or $800 AUD in Australia?

Frequently Asked Questions: Is 85% Battery Health Good on a Refurbished iPhone? (Lab Truth)
How long does an 85% to 88% battery health iPhone last per charge?
On modern models like iPhone 13, 14, 15, and 16, 85%-88% health retains roughly 85%-88% of original mAh runtime, comfortably covering a full standard Australian workday of calls, messaging, banking, and CarPlay.
What does Genuine, Used, or Unknown Part mean in iOS Settings -> Parts & Service History?
iOS records whether a component is original factory-paired, a calibrated Used/Genuine Apple part, or a third-party module. PRC discloses replaced parts transparently and verifies True Tone, touch scan rate, and thermal draw on the bench.
Are refurbished or second-hand phones waterproof for swimming?
No. Even brand-new manufacturer warranties exclude liquid damage because rubber/adhesive seals age over time. PRC installs fresh frame seals during any bench service for everyday splash resistance, and advises keeping all phones out of water.
How do I check if a used iPhone has a hidden motherboard reboot fault?
Open Settings -> Privacy & Security -> Analytics & Improvements -> Analytics Data, search for panic-full, and paste any log free into www.prcrepair.com.au/iphone-panic-log-analyzer.
