How to Use Dual Sim & SD Card Simultaneously in Hybrid Slot

The new Samsung Galaxy S7 Edge is an amazing phone. Those who are dual sim phone owners must be disappointed that you can either choose Extra Space; or Dual Sim with internal space.

Well, if you are willing to do a little bit of hack, you will be able to use Dual Sim and MicroSD space on Samsung Galaxy Edge S7.

Here are the RISKS if you decided to proceed with the hack;

1. Your Nano sim will not be able to reuse again (replacement new nano sim).
2. Your Micro SD Card may attach to the Nano Sim. Forever
3. Prepare to walk into your Telco and get a replacement of Nano Sim, if it failed to work.
4. One of your Nano sims need to be your permanent line; because it’s attached to your Micro SD Card.
5. If you didn’t do it right, you might break your S7 Edge 🙂

So, I have a primary line; which I use daily i.e Celcom Line, alternatively sometimes I hop on Mobile (a lot of data 3GB…), so I’ve decided to hack on my Celcom Nano sim, and Mobile will be… an on and off sim which allows me to plug into slot 1; besides if you travel a lot, can use to plug the travel sim card into slot 1 too.

Prepare Your Tools

Here are the simple tools I am using to hack the Nano sim.

1. Nano Sim (MUST BE Nano Sim because it’s easier to cut and remove)
2. Lighter
3. Scissor
4. Double side tape OR Uhu/Elephant/Gajah Super Glue. (I used double sided tape because I love the free MicroSD card from Samsung)
5. MicroSD Card.
6. Read the next line

Step 1: Make Sure the Nano Sim Card Placing is Correct.

Here are 2 SIMs (Mobile and Maxis) I am using to do the comparison, which one should face up/down.

Maxis Hotlink Sim Card

Mobile Sim Card

I notice that all the sim card (included Celcom, shown later), have a breaking part. that should give you an indication which one is Up or Down.

UMobile Sim Breaking off part

So now you should know which part should face up/down using looking at the breaking part on the sim card.

Step 2: Removing the chip from Nano Sim

Heat up the Nano Sim (the plastic side ok) for 30 secs to 1 minutes, and use your finger/sharpen tools to remove the chip out from the nano sim card. It should look like this…

By now, you are almost 50% done with the work 😉 If it’s not successful, it’s time to walk into your cells and do sim replacement 😉

Step 3: Trim Nano Sim Chip and Attach to MicroSD Card

If you want to play safe and don’t salvage your MicroSD Card, you can use double sided tape attach the nano sim and MicroSD Card together. But before that, make sure you trim the Nano Sim Chip and make it just nice (am-am) fix into MicroSD Card.

Which part should I trim it? Refer to picture below.

Trim/Cut off both side of the nano sim chip

I use scissors cutting off both side, 1mm to 2mm (well I didn’t measure, just by gut feeling). We move on next, you may need to trim the nano sim chip.

Step 4: Attach Nano Sim Chip onto MicroSD Card

Now, here is the part, attach the Nano Sim Chip onto MicroSD Card. Refer to picture below for more explanation.

Attach Nano Sim Chip onto MicroSD Card

So, if you MicroSD chip reading if on your ride, your Nano Sim Chip Breaking part should face up highlight in Orange color.

Besides, make sure the Nano Sim Chip is aligned to the corner of your MicroSD Card as highlighted in RED color.

You are about there!

Step 5: Placing the MicroSD Nano Sim onto Samsung Galaxy S7 Edge Tray

So, placing the MicroSD Nano Sim onto your S7 Edge tray and get ready to activate the dual sim, I attached with Maxis sim card for testing.

Flip it over, make sure the Nano Sim Chip is aligned on the corner as Highlight in the Red Square. Alright, slot it into your Samsung Galaxy S7 Edge!

Final Step: Configure with Dual Sim Manager

If you see picture below on your Samsung Galaxy S7 Edge, that mean now your S7 Edge is enabled with Dual Sim and Expanded MicroSD Card Storage! Congratulation!

Now you should head over and configure your data sim/call sim / 4G LTE network sim with Dual Sim Manager.

For those who failed on Step 2, don’t give up, get a new nano sim and do it again 😉

Here is the Sim card manager
