How to Convert Single SIM Phone Into Dual SIM PhoneNikitha Sharma
RoyTecTips shows us an ingenious hack which turns a single-SIM-slot phone into a fully functioning dual-SIM phone. All that needed for this hack is a heat-gun, solvent, micro SD card, nano SIM and some glue. The trick is that the phone has a SIM reader on the backside of an SD-card slot. Through some detailed dissection and reconstruction work, you can piggy-back the SIM on the SD card and have them both work at the same time.
Making the SD/SIM Franken-card is no picnic. First you start by filing away the raised bottom edge of the micro SD card and file down the side until the writing is no longer visible. Next get a heat gun and blast your nano SIM card until the plastic melts away. Then mark where the SIM card’s brains go and glue it on. Turn the phone on then, hey presto, you now have a dual SIM phone while keeping your SD storage.
This hack is reported to work on many Samsung phones that end in “7” and some that end in “5”, along with some 8-series phones from Huawei and Oppo clones of the Samsungs. Since you’re only modifying the SIM card, it’s a fairly low-risk hack for a phone. Combining two cards into one is certainly a neat trick, almost as neat as shoe-horning a microcontroller into an SD card. We wonder how long it will be before we see commercial dual SIM/SD cards on the market.
