Using a smartphone that supports two SIM cards isn’t surprising nowadays. The functionality, also called dual SIM, is an industry-standard thanks to hybrid SIM slots. And even though there might be a difference between slots 1 and 2, the added flexibility has many benefits a single SIM card doesn’t. You can use one SIM card strictly for mobile data while texting and calling using another SIM card by another carrier. Also, we’d like to remind you to double-check that you chose a dual SIM version of the smartphone before you order it. Here are the best dual SIM card phones to use in 2021.
1. Samsung Galaxy S21 5G
We’ll start with the most apparent spec – the 6.2-inch Dynamic AMOLED 2X screen. It has a resolution of 1080 x 2400 pixels, a refresh rate of 120 Hz, and a peak brightness of 1300 nits, and supports HDR10+. The phone ships in 4 CPU variants, although we’d love to see Qualcomm Snapdragon 888 5 nm in action the most. The camera on the back is a triple-lens (12 MP+64 MP+12 MP) capable of recording in 8K at 24 fps or 4K at 60 fps, while the selfie camera is only 10 MP. Samsung Galaxy S21 has two storage variants, 128GB and 256GB with no card slot, and ships with 8GB RAM and a 4000 mAh Li-Ion battery.
2. Apple iPhone 12 Pro Max
Apple iPhone 12 Pro Max is a beautiful smartphone with dual SIM support. First, we’ll mention the 6.7-inch Super Retina XDR OLED screen with HDR10 and Dolby Vision support, a resolution of 1284 x 2778 pixels, and typical/peak brightness of 800/1200 nits. You can’t miss the triple camera setup on the back either (12 MP+12 MP+ 12 MP) with a TOF 3D LiDAR depth scanner, capable of recording in 4K at 60 fps. To ensure blazing-fast performance, Apple iPhone 12 Pro Max uses an NVMe drive with 256/256/512GB of capacity. It combines it with a Hexa-core 5nm Apple A14 Bionic CPU, 4-core Apple GPU, and 6 GB of RAM.
3. Huawei Mate 40 Pro
Don’t let the lack of Google services deter you from getting Huawei Mate 40 Pro, Huawei’s top dual SIM card phone. Its best-selling feature is the triple camera with Leica optics (50 MP/12MP/20MP) which supports recording in 4K at 60 fps. The 6.76-inch OLED, 90Hz, HDR10 screen with a resolution of 1344 x 2772 pixels and the Kirin 900 5G 5nm CPU coupled with Mali-G78 MP24 aren’t behind either. The phone also comes with a Li-Po 4400 mAh battery and two storage solutions, 256 GB and 512 GB paired with 8 GB of RAM.
4. Xiaomi Mi 11
We’ll begin with the craziest Xiaomi Mi 11 specification. That’s a triple back camera setup (108 MP+13 MP+5 MP) capable of recording in 8K at 24 to 30 fps. This is followed up with a 6.81-inch AMOLED screen, featuring a resolution of 1440 x 3200 pixels. The screen can display 1 billion colors, has a peak brightness of 1500 nits, features a 120 Hz refresh rate, and supports HDR10+. Xiaomi Mi 11 also has an Octa-core Qualcomm Snapdragon 888 5 nm CPU paired with an Adreno 660 GPU. The best version has 12 GB of RAM and a 4600 mAh Li-Po battery.
5. OnePlus 8T
OnePlus 8T is a superb dual SIM card phone, no doubt about it. You’ll certainly love its 6.55-inch Fluid AMOLED screen with a resolution of 1080 x 2400 pixels, 120Hz refresh rate, and support for HDR10+. Another spec that catches the eye is the 7nm+ Octa-core Qualcomm Snapdragon 865 CPU paired with an Adreno 650 GPU. You’ll also love its quad camera on the back (48 MP+16 MP+5 MP+2 MP and the 16 MP single camera on the front. But what will undoubtedly take your breath is the Li-Po 4500 mAh battery. It goes from 0% to 100% in only 39 minutes with 65W fast charging.
6. Oppo Reno5 Pro 5G
Oppo Reno5 Pro 5G has a 6.55-inch Super AMOLED screen with a 90 Hz refresh rate, support for HDR10+, and a typical/peak brightness of 800/1100 nits. Another spec that makes it stand out is certainly its quad-camera (64 MP+8 MP+2 MP+2 MP), which “only” records in 30 fps at 4K. Oppo also justified their front camera advertisements with a 32 MP front camera with HDR support. We also suggest you pick the 256 GB ROM/12 GB RAM version if you plan to future-proof. Although unspecified, it won’t take long to fill up the 4350 mAh Li-Po battery thanks to 65 W fast charging support.
7. LG V60 ThinQ 5G
LG’s contender to the throne of phones that use dual SIM is LG V60 ThinQ 5G. The phone has a P-OLED 6.8-inch screen with HDR10+ support and a 1080 x 2460 pixels resolution. It also has a Qualcomm Snapdragon 865 CPU and an Adreno 650 GPU, which is a usual pair. What is unusual, however, is the triple camera on the back (64 MP+13 MP+0.3 MP) which can record in 8K at 30 frames per second. Another unusual spec is the larger-than-usual 5000 mAh Li-Po battery. LG V60 ThinQ 5G comes in two storage versions, 128 GB and 256 GB, but only in an 8 GB RAM variant.
8. ASUS ROG Phone 3 Strix
If you need a gaming dual SIM card phone, ASUS ROG Phone 3 Strix has you covered. The screen size, 6.59-inches, or resolution, 1080 x 2340 pixels likely won’t impress you. Even HDR10+ support and 650 nits of typical brightness aren’t special. But what is outstanding is the 144 Hz screen refresh rate. The triple camera setup (64 MP+13 MP+ 5 MP) excels equally, and you can record in 8K at 30 fps. Another area ASUS ROG Phone 3 Strix dominates in is RAM – 8G or 12 GB. But what truly sets it apart except that it’s a little thicker are unique, addressable, software-controlled RGB lights on the back.
9. Motorola Edge S
Motorola Edge S is an affordable dual SIM card phone that will have a great price-to-performance ratio. The phone has a 6.7-inch IPS LCD screen with a resolution of 1080 x 2520 pixels. The screen also supports HDR10, has a 90 Hz refresh rate, and typically hovers at 560 nits of brightness. For CPU and GPU, Motorola Edge S uses Qualcomm Snapdragon 870 5G and Adreno 650. You’ll also love the quad camera on the back. It has a resolution of 64 MP+16 MP+ 2MP (depth)+TOP 3D depth sensor. As such, it can record in 6K at 30 fps and 4K in 60 fps. And, just like LG V60 ThinQ, it has a Li-Po 5000 mAh battery.
10. Realme X7 Pro
Realme X7 Pro is a great choice for a dual SIM smartphone. You just have to look past its relatively unknown brand name, that’s all. It has a 6.55-inch AMOLED screen with a refresh rate of 120Hz and a resolution of 1080 x 2400 pixels. The Quad camera on the back (64 MP+8 MP+2 MP+2 MP) also stands out. On the other side, the front camera has a resolution of 32 MP. Another interesting Realme X7 Pro specification is the 4500 mAh battery. It supports 65W fast-charging and goes 0% to 100% in only 35 minutes. As for ROM and RAM, you can pick 128GB/6GB, 128GB/8GB, and 256GB/8GB variants.
