[ASMR] iPhone 17 Pro Max Physical SIM Card Mod | Easy Swap Freedom & 256GB to 1TB Lossless Upgrade!

This locked US iPhone 17 Pro Max was specially sent all the way here by one of our loyal fans, and we’re giving it a full hardcore upgrade with two key solutions! We’ve done a perfect dual physical SIM modification to get rid of the restriction that US models can’t support dual physical SIM cards, and upgraded the internal storage from 256GB to 1TB to fully solve daily storage anxiety—bringing this phone as close as possible to a China unlocked version experience in one go!
We did a meticulous full teardown, with full protection for core components like Face ID and cameras throughout the whole process to avoid any damage. We removed the original Toshiba 256GB S5E flash chip, and completed standardized solder pad preparation, flash reballing, 1TB chip installation and BGA encapsulation strictly by the book. Once finished, the internal look is almost identical to the factory original with no obvious modification traces.
At the same time, we installed a long-term stable dual SIM modification—this is by far the most reliable dual SIM tweak for the iPhone 17 Pro Max. There’s no need to replace the charging port flex cable, and all excess flex cables can be neatly hidden away.
When reassembling the device, we found a critical safety hazard: the SIM tray was pressing hard against the battery. We used a professional non-destructive tool to remove the battery without any damage, adjusted its position slightly and left ample safe clearance, eliminating the risk completely.
After finishing both upgrades, we cleaned off all residual adhesive inside the chassis, applied new factory-grade waterproof glue, and did a pressure test to restore the phone’s airtightness. After flashing the system and activating the phone, dual SIM signals pop up instantly, the 1TB large capacity is perfectly recognized, and benchmark scores return to normal.
There’s only one small reminder: the SIM ejector pin hole has no waterproof design after modification, so you need to be a little careful with it in daily use.
After this full hardcore upgrade, this phone is virtually indistinguishable from a China unlocked version, with top-tier smoothness and maximum durability!
