There are plenty of dual SIM phones on the market these days, but most of them are a hamstrung by packaging issues. Despite their dual SIM capability, this usually comes at the expense of the microSD card slot. Of course, hackers don’t accept such nonsense, and [Tweepy] went about crafting a solution. Sadly the make and model of phone aren’t clear.
It’s a simple case of very carefully shaving both the microSD card and the nano-SIM down until both can fit in the card tray. The SIM is slimmed down with the application of a heat gun helping to remove its plastic backing, saving precious fractions of a millimeter. The SD card is then filed down to make just enough space for the SIM to fit in underneath. Thanks to the springiness of the contacts in the phone, it’s just barely possible to squeeze both in, along with some Kapton tape to hold everything in place.
Your mileage may vary, depending on the construction of your SD card. Overall though, it’s a tidy hack that should prove useful to anyone with a dual SIM phone and limited storage. We saw a similar hack a few years ago, too.

[RoyTecTips] shows us an ingenious hack which turns a single-SIM-slot phone into a fully functioning dual-SIM phone. All that’s 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.
[Update] I got a little confused on this one as we only have the single sim variants of these phones where I live. this hack is for dual sim phones that either accept 2 sim cards or 1 sim + 1 SD card. This hack solves this problem and allows 2 sims plus 1 SD card in these phones. Sorry for the confusion and thanks to all who pointed this out in the comments.
