The best dual-SIM Android phones let you seamlessly use two SIM cards at the same time. Dual-SIM phones have always been popular in Asian countries, and they're now starting to gain momentum in Western markets. With a dual-SIM phone, you can still use your primary SIM and pick up a local SIM to use on the same device while traveling, negating the need to carry two phones.
The power you need
OnePlus 8T
Staff pick
The OnePlus 8T is one of the fastest phones you can buy today. It features the Snapdragon 865 chipset and a sublime 120Hz AMOLED display, and there's 65W fast charging, 12GB of RAM, and 256GB of storage out of the box. Oh, and you get Dual SIM Dual Standby, allowing you to use two SIM cards at the same time.
The affordable choice
Nokia 3.4
The Nokia 3.4 combines decent hardware that's reliable in day-to-day use with a large 6.39-inch 720p screen and 4,000mAh battery. You're buying this for the convenience; the Nokia 3.4 works on all carriers in the U.S. and has a dual SIM card slot that lets you use two numbers at the same time, and it has Dual SIM Dual Standby.
Switch to 5G
Google Pixel 4a 5G
The Pixel 4a 5G is a fantastic mid-range phone, delivering clean software, outstanding cameras, 5G connectivity, and fast updates. While the phone has a single SIM card slot, it also works with eSIM, giving you the option to use two numbers. You can switch to eSIM for your primary number and use the physical SIM card slot for a secondary number — but there's no Dual SIM Dual Standby.
Best on a budget
Redmi Note 9 Pro
The Redmi Note 9 Pro is not available officially in the U.S., but you can pick it up unlocked on Amazon. You'll want to do so because the phone has powerful hardware, a vibrant FHD+ screen, insane battery life, and standout cameras. It has a dual SIM card slot and offers Dual SIM Dual Standby by default, and works on AT&T as well as T-Mobile.
Ultimate value
Samsung Galaxy S20 FE (Global)
Because of carrier pressure, Samsung doesn't offer dual-SIM models for sale in the U.S. However, you can get the global version of the Galaxy S20 FE on Amazon. The device features the Exynos 990, which is on the level of what you get in the U.S. model. You still get the same excellent value, with the added benefit of a dual SIM slot and Dual SIM Dual Standby, and it works on AT&T and T-Mobile.
Insane battery
POCO M3
The POCO M3 has a gorgeous design, two-day battery life thanks to the 6,000mAh battery, large 6.5-inch FHD+ screen, and reliable hardware. Oh, and you're also getting a huge value here. The phone has a dual SIM card tray, offers Dual SIM Dual Standby, and has LTE bands for AT&T and T-Mobile.
These are the best dual-SIM Android phones
The best Android phones all come with a dual-SIM card option, but because of the carrier-driven ecosystem in the U.S., phone manufacturers like Samsung disable this feature in the country. That said, things are changing for the better, and you can still find plenty of options that are officially available in the country with a dual SIM card slot.
The best choice at the moment is the OnePlus 8T; the hardware on offer here should last you well for several years, and there's 12GB of RAM and 256GB of storage along with an insane 65W fast charging system. The OnePlus 8T also has decent cameras, software that's very well optimized for the hardware, and is a fantastic choice if you want a phone with dual-SIM connectivity.
While there are global unlocked versions of the Note 20 Ultra and Galaxy S21 series up for sale on Amazon U.S., it's not worth the hassle of missing out on warranty, particularly on flagship phones.
If you need a more budget-focused option, the Redmi Note 9 Pro is the obvious choice. Motorola and Nokia sell a lot of budget phones in the U.S., but if you're willing to lose out on warranty by picking up the Redmi Note 9 Pro, you'll get much better hardware and a great overall value. Same goes for the POCO M3; there's no other phone that comes close to the M3 in the U.S. in terms of value in this category.
