5 Best Dual SIM Phones With Dedicated Expandable MicroSD Card Slot in 2018

Dual SIM smartphones are available in abundance right now. However, there aren’t a lot of good ones out there. The impression that dual SIM phones are only used in emerging markets or Asian regions is not entirely true. However, manufacturers mostly bring dual SIM variants of their flagships to European and Asian markets. There’s no denying that dual SIM phones have utility practically anywhere in the world, considering how it allows you to separate your work number from your personal numbers.

Although there are a handful of dual SIM phones in the world today, some of them make the compromise of offering the second SIM card slot with a microSD card slot. This means that you can either use a second SIM card or a microSD card slot, but not both. However, there are a few smartphones today, especially in 2017, which come with both microSD and second SIM card slots. This allows you the liberty to use both SIM cards as well as the microSD card if you find the storage to be lacking. We’re going to have a look at some of these smartphones today, so be sure to check them out and have your pick.

Samsung Galaxy S8+

The Galaxy S8+ comes with a 6.2-inch Quad HD Super AMOLED display, accompanied with a 12-megapixel f/1.7 rear camera, an 8-megapixel f/1.7 front camera, the octa-core Exynos 8895 chipset, 64/128GB of expandable storage, 4/6GB of RAM, Android 7.0 Nougat, and a 3,500 mAh battery.

The handset is one of the most popular offerings in the market right now. Although Samsung is heavily focused on the launch of the Galaxy Note 8 right now, the Galaxy S8 and the S8+ remain incredibly popular in the markets today. The handset comes with the company’s Infinity Display, which is the company’s curved display panel that stretches all the way to the sides.

The phone also comes with features like DeX which allows you to use the phone with a compatible desktop. Given that it’s a Samsung smartphone, there’s no dearth of attractive features on board. The phone also comes with Bixby voice on board, which only works in the U.S. and South Korea as of now. This particular variant is currently available for $729.49 via Amazon.

Sony Xperia XZ Premium

Sony’s 2017 flagship, the Xperia XZ Premium is a showstopper in terms of hardware specs. In addition to packing a microSD card slot and a SIM 2 slot, the phone also comes with a 5.46-inch UHD 4K resolution display. Further, there’s a 19-megapixel rear camera, accompanied by a 13-megapixel front camera. In terms of processing power, the Xperia XZ Premium is packing the octa-core Snapdragon 835 SoC on board.

The phone also comes with 4GB of RAM, 64GB of expandable storage, Android 7.1 Nougat, and a 3,230 mAh battery. If that’s not good enough, the phone also comes with IP68 certified water/dust resistance on board, making it one of the most durable flagships currently available in the market. There are stereo speakers on board as well, so there’s something here for everyone.

Sony smartphones are predominantly sold in European and Asian markets. However, thanks to online retailers in the U.S. customers can get them in the region as well. You will have to shell out $794.46 for the smartphone. It’s pretty hefty, but an excellent handset to own if you’re looking for a top shelf flagship with dual SIM and microSD expansion.


The HTC U11 was rated as one of the best cameraphones available in the market. This is a title that the handset still holds, so it is of great significance to tech experts. The phone is available in two variants depending on the region. While the American model comes with single SIM support, the global model packs a dual SIM card slot and a microSD card slot for increased options.

In the hardware department, the HTC U11 comes with a 5.5-inch Quad HD display, a 12-megapixel f/1.7 rear camera, a 16-megapixel f/2.0 front camera, the octa-core Snapdragon 835 chipset, 4/6GB of storage, 64/128GB of expandable storage, Android 7.1 Nougat, and a 3,000 mAh battery. The phone also comes with IP67 certification and is partially water and dust resistant. The handset might not be able to survive full blown submersions, but should be able to withstand a splash or two.

The handset can be snatched from Amazon for just $649, which is pretty reasonable compared to other flagship offerings available in the industry today.


Much like the handsets above, the LG G6 also has a dual SIM variant focused on the international markets. The handset didn’t make much noise in the industry when it was launched, but that was mainly due to the fact that the handset couldn’t compete against the likes of the Galaxy S8 and the S8+. However, if you’ve been an LG fan or are simply contemplating a switch, it makes sense to try this out.

With the LG G6, the users are treated to a 5.7-inch Quad HD display, dual 13-megapixel rear cameras, a 5-megapixel front camera, the quad-core Snapdragon 821 chipset, 32/64/128GB of expandable storage, 4GB of RAM, Android 7.0 Nougat, and a 3,300 mAh battery. The phone is IP68 certified for water/dust resistance and it also comes with MIL-STD-810G certification for durability. The handset can be snatched up for $484.99 via Amazon right away.

Samsung Galaxy A7 (2017)

The Galaxy A7 comes with a 5.7-inch Full HD Super AMOLED display, 32GB of expandable storage, 3GB of RAM, a 16-megapixel rear camera, a 16-megapixel front camera, Android 6.0.1 Marshmallow, and a 3,600 mAh battery. The phone comes with Samsung’s own Exynos 7880 chipset, so the performance probably won’t be on par with the Qualcomm Snapdragon chipsets.

The Galaxy A7, despite being a mid-ranger comes with features like a fingerprint scanner and a USB C port. Thanks to the presence of a fingerprint scanner, Samsung is bringing support for its wireless payments service, Samsung Pay. The addition of features like this will go a long way in making this an exciting mid-ranger. The phone also comes with IP68 certification for water and dust resistance.

The handset can be snatched up via Amazon for just $368.49 right now, making it the cheapest offering on this list right now.

  1. There is more than 2 SIM slots and a MicroSD. I haven’t checked phones on the list yet, but there are phones with the 2nd SIM Slot supporting only 2G only, making the 2nd SIM useless.

  2. I am selling this stuff and I know very well which have a dedicated slot for micro sd card. As stated earlier non of these offer a dedicated micro sd slot except Samsung Galaxy A7 2017. Then also the smaller brother Samsung Galaxy A5 2017 offers a dedicated slot. And ofcourse the J7 2017. If you want a better phone or the best, then forget it. You have to stick to a hybrid slot for the second sim and micro sd.

  3. Correction 2: Both Samsung A7 and (!) J7 (not in your list) have dedicated MicroSD card slots. All others remain to be phones with hybrid slot.

    Just recently XIAOMI announced a Dual-SIM phone with dedicated MicroSD slot. All 3 cards are on one tray. So there is hope that other manufacturer will follow since XIAOMI is a very fast growing chinese manufacturer (already No. 4 worldwide) but with good quality and fair prices. Source:

  4. incorrect article. NONE of these phones offer a dedicated SD card slot + Dual sim.
    No idea why phone manufacturers have decided this is the way to go.. I’m sticking with my LG G4 until something suitable comes along.
