Very rarely mentioned in the same breath as zippy 64-bit processors, Quad HD screens, OIS cameras, or massive batteries with fast charging capabilities when it comes to top selling points of today\u2019s best and brightest Android smartphones. Dual-SIM support remains an extremely convenient feature to have for several classes of mobile users. Business people often want to keep their professional and personal lives separate. Budget consumers in emerging markets need multiple SIM cards to avoid spending a fortune on calling different people on different operators, while travelers may find it easy to use a number domestically and another one abroad. Clearly, getting a dual SIM smartphone is wiser and cheaper than buying multiple devices, each with its own subscriber identity module. And the best news of all is you can find such models of popular gadgets in virtually every possible price bracket. What is the best dual SIM smartphone, you ask? It really depends on how much you\u2019re willing to cough up and what other requirements you have. Here\u2019s a comprehensive list, including both dual active and dual standby products: OnePlus 6T First up is the OnePlus 6T. Launching as one of the more higher-end smartphones just a few months back, this one comes with some excellent Dual SIM capability.\u00a0 With the OnePlus 6T, you're getting a massive 6.41-inch display with a top tier resolution. That said, viewing and consuming media on this device is fantastic because of the crisp, clear clarity. This one handles tasks really well, too, all thanks to the Snapdragon 845 processor and a whole 6GB of RAM. With that much memory, you'll be able to run multiple apps and multitask like nobody's business. It's also running the latest version of Android -- Android 8.1 Oreo below OnePlus' OxygenOS system.

However, keep in mind that most versions of this phone are not sold in a Dual SIM variant -- you have to buy it in the Dual SIM format individually. You just can't buy it from AT&T, Verizon, Sprint, and T-Mobile and expect to get Dual SIM support. You have to buy it online. As far as hardware goes, you get a 5.8-inch display with a high resolution -- a whole 2,960 x 1,440. There's 6GB of RAM, and then the Snapdragon 845 processor. And, of course, you'll be able to enjoy everything that Android Oreo offers, and soon enough, Android Pie. Buy it now: Amazon Sony Xperia Z3 Plus The Xperia Z5 and Z5 Premium must wait, which gives the \u201cOG\u201d hero one final chance to shine. This one has octa-core Snapdragon 810 muscle on deck, 20.7 MP photography greatness, water resistance, and active dual SIM capabilities. This allows you to talk on one number and still receive calls from the other, instead of the caller being automatically sent to voicemail. Huawei P20 Pro Huawei, being the international smartphone manufacturer that it is, has traditionally offered Dual SIM support in its smartphones, and the P20 Pro is no different. It's got the Dual SIM tray for your choice of two (compatible) GSM networks. It has a massive 6.1-inch display, sporting a resolution of 2,240 x 1,080.

There's 6GB of RAM, too, making this a perfect choice for multitasking. Buy it now: Amazon Samsung Galaxy Note 9 If you're looking for a big, powerful device, look no further than the Samsung Galaxy Note 9. Just like the Samsung Galaxy S9, you can grab a Dual SIM variant online from Amazon -- the ones sold through your traditional carrier don't come with that Dual SIM support, unfortunately. Looking at the hardware, the display itself comes in at a whopping 6.4-inches in size, and with that Super AMOLED panel, that really brings out its colors. The highlight of this phone is that it comes with a stylus pen, bringing a bunch of new productivity features to the phone. You get a Snapdragon 845 CPU, plenty of RAM, and pretty sweet camera setup.

Not too, shabby! Sony Xperia M4 Aqua The only reason we\u2019d recommend this thing over all the other dual SIM contenders, save for the Z3+, is its excellent IP68 certification for water protection up to 1.5 meter and 30 minutes. Just don\u2019t be tempted to snap 13 megapixel pics deep in the ocean or at the neighborhood swimming pool, because chances are Sony\u2019s warranty will not have you covered. Pocophone F1 Xiaomi's Pocophone F1 is another excellent choice for those in search of a dual SIM model. It has a beautiful display and features a Snapdragon 845 processor, 6GB of RAM, and a 6.1-inch display. It's GSM Unlocked and comes equipped with the competitive dual camera setup. You can't get this one from a carrier but can buy it straight from Amazon. BLU Studio C Now that\u2019s how a super-affordable phone should look in this day and age. The 5-inch Studio C is colorful, respectably powerful, touts a phenomenal camera, massive 3,000 mAh battery, Android 5.0, beautiful HD screen, and last but not least, dual SIM with nationwide GSM HSPA+ compatibility. That\u2019s not full 4G LTE, but it\u2019s remarkable nevertheless at a measly Benjamin.
