The OnePlus Open has been making waves in the smartphone market with its innovative designs and cutting-edge features – but is the OnePlus Open Dual SIM? The network and connectivity benefits of having a Dual SIM device are leaving more smartphone users considering whether or not their device is capable of handling two SIM cards at once. In this article, we’ll delve into the details to provide you with a definitive answer to this very question. Whether you’re a tech enthusiast or a potential OnePlus Open buyer, this article will equip you with the knowledge you need.

Understanding Dual SIM technology

Before we dive into the specifics of the OnePlus Open, let’s take a moment to understand what Dual SIM technology actually is. Dual SIM-compatible phones are designed to accommodate two SIM cards, allowing users to have two separate phone numbers and plans on just one single device. This feature is particularly useful for individuals who want to separate personal and work calls, or for frequent travelers who need to use different SIM cards in different countries.

Is OnePlus Open a Dual SIM device?

Now, let’s address the burning question: is the OnePlus Open a Dual SIM device? Well, the answer is yes! The OnePlus Open comes with Dual SIM capabilities, allowing you to use two SIM cards simultaneously. This feature provides flexibility, convenience, and the ability to manage multiple phone numbers and plans from a single device.

The benefits of Dual SIM phones

Having a phone like the OnePlus Open that’s compatible with two SIM cards comes with several advantages. Let’s explore some of the key benefits:

Convenience and flexibility

With a dual SIM phone, you no longer need to carry two separate phones or constantly switch SIM cards. You can have both your personal and work numbers on a single device, eliminating the need for multiple devices and simplifying your life.

Cost savings

Dual SIM phones can also end up saving you money: instead of paying for two separate mobile plans, you can take advantage of different plans and promotions from different carriers. This allows you to choose the most cost-effective options for voice calls, data, and messaging as you see appropriate.

Enhanced Coverage and Connectivity

Additionally, having two SIM cards means you can connect to multiple networks simultaneously. This can be particularly useful when traveling to areas with weak coverage, or when you need to switch between networks to ensure a stable connection.

Does this mean I can use both SIM cards simultaneously for data?

Yes, you can use both SIM cards simultaneously to access network data. In fact, you can allocate data usage to a specific SIM card based on your personal preferences.

Can I receive calls on both SIM Cards at the same time?

Yes, the OnePlus Open supports dual standby, which means you can receive calls on both of your SIM cards simultaneously. This feature just has to be enabled in the Dual SIM settings menu, but however, you can only actively use one SIM card for calls at a time.

Does the OnePlus Open support eSIM?

Upon its initial October 2023 release, the OnePlus Open did not have support for eSIM, but luckily for users, a November update saw a software advance come to the device enabling eSIM support globally. Essentially, having an eSIM allows you to activate a network plan without the need for having a physical SIM card. Instead of having a removable card, an eSIM consists of software installed onto an eUICC chip that’s permanently attached to a device, in this case, your OnePlus Open.


The OnePlus Open is indeed a Dual SIM device, providing users with the flexibility and convenience of managing two phone numbers on a single device. With the ability to set a default SIM card, customize data and call preferences, and switch between SIM cards, the OnePlus Open offers a seamless Dual SIM experience. Whether you need to separate personal and work calls, take advantage of different carrier plans, or even leverage 5G data, the OnePlus Open has you covered.
