How to enjoy dual-SIM and micro SD simultaneously on the Galaxy S7


The Galaxy S7 and S7 Edge are sold in the UK with a dual-function tray: one end is for a micro SD card, and the other is for your nano SIM. It’s all pretty standard and boring. Elsewhere, though the S7 is available as a dual-SIM device, with a slightly different tray which allows you to slide in a second SIM instead of the Micro SD card.

The dual-SIM Galaxy S7 and S7 Edge opens up some intriguing possibilities… namely, fitting two SIM cards and a Micro SD in one tray. Surprisingly, this is quite possible, if a bit risky, thanks to some clever engineering by a Malaysian engineer called Noreplied.

Check out our instructions (in full) before getting started… and here’s our standard disclaimer:

Warning: You can break your SIM card, Micro SD card and/or Galaxy S7 Edge by following these instructions. We’re not liable for any damage. Be careful.

Step 1: Assemble your materials

You know that you’re going to have an interesting time when your list of required items to modify your phone includes super glue (or double-sided tape), scissors and a lighter. Of course, you’ll also need a dual-SIM Galaxy S7 or S7 Edge, two nano SIM cards, a Micro SD and some strong nerves.

Step 2: Note the position of your nano SIM card

Once you’ve assembled your equipment, the operation can begin. First, put your less important SIM into the second slot and turn it over, noting the slightly asymmetric design that lets you figure out which way around it’ll fit later. You might want to take a photo to ensure you remember which way up it goes.


Step 3: Free your SIM card from its plastic casing

Now you need to take the actual functional bit of the SIM card out of its surrounding plastic. Do this by heating up the plastic side of the SIM card for 30-60 seconds (CAREFULLY!), then separating the two layers using your fingernail or another small implement.


Step 4: Trim both sides of the SIM card

Now for another hairy bit: trim both sides of the SIM card using a pair of scissors. You’ll need to take out about one or two millimetres on each side, as highlighted in orange below. This allows the SIM card to fit onto the Micro SD card without issues.


Step 5: Attach the SIM to the Micro SD card

Now for the easy part. Attach the cut SIM card to the underside of your nano SIM card, comparing with the photo or notes you made earlier to ensure it’s the right way up. Once you’re satisfied it’s correct, add your double-sided tape or glue, then replace it in the same position. You’ll want to ensure that the nano SIM’s corner aligns with the edge of the Micro SD card, as highlighted in red below.


Step 6: Insert the combined unit into the S7’s tray

Now it’s time to cross your fingers and hope for the best. Place your combined nano SIM / Micro SD card into the tray, ensuring the nano SIM’s corner aligns with the corner of the tray, as highlighted in red below. When you’re satisfied it’s in position (and re-taped if it’s not), then slide it into your phone.


Step 7: Check that everything’s worked in Settings

Once inserted, with a bit of luck you should be done. Check Settings > SIM card manager to see that both SIMs have been recognised correctly, and then check Settings > Storage to ensure that the Micro SD card is working too.

As you can see in the screenshots below, it actually is possible – you can see two SIMs below the brightness setting, and a 128GB card successfully being registered below that. Awesome!



So there we have it – a pretty incredible mod for the Galaxy S7 and S7 Edge. Read through the instructions a few times before actually trying it for yourself, and feel free to check out Noreplied’s original instructions as well if anything’s not clear.
