Absolutely! If your phone has only one physical SIM card slot but supports eSIM technology, you’ve got a dual SIM device in your hands. This powerful combination allows you to use two different mobile plans on a single phone, unlocking a world of flexibility for travel, work, and personal use.
Many modern smartphones, including popular models like the iPhone SE and Google Pixel a-series, are built this way. You can keep your primary physical SIM card for your main number and add a Yoho Mobile eSIM for affordable, high-speed data when you travel. Ready to see what’s possible?

How a Single SIM Slot Phone Achieves Dual SIM Functionality
The magic behind this feature is the combination of one physical component and one digital one. Your phone has:
- One Physical SIM Slot: This is the traditional tray you slide your nano-SIM card into.
- One Embedded SIM (eSIM): This is a small chip permanently built into your phone’s motherboard. It functions as a digital SIM card that you can program with a mobile plan without needing a physical card.
Together, they enable what’s known as Dual SIM Dual Standby (DSDS). This means both lines—your physical SIM and your eSIM—are active and can receive calls and texts. You can then choose which line to use for mobile data. This embedded SIM technology, standardized by the GSMA, is the key to unlocking dual SIM capabilities on your single-slot device.
Unlocking the Power of Dual SIM: Key Benefits
Using an eSIM alongside your physical SIM offers several practical advantages, especially for travelers and professionals.
- Seamless International Travel: This is the most popular use case. Imagine you’re traveling from the US to Japan. You can keep your US number active on your physical SIM for important calls or SMS verifications, while using a Yoho Mobile Japan eSIM for affordable, high-speed data. This helps you completely avoid expensive international roaming charges.
- Separate Work and Personal Lines: Manage two phone numbers on one device. No need to carry a second phone for your business line. You can easily distinguish between work and personal calls.
- Network Flexibility: Combine carriers for better coverage. If one network is weak in a certain area, you can switch to the other for your data connection, ensuring you’re always connected.
Setting Up Your eSIM on an iPhone SE or Pixel a-series
Activating your eSIM is a straightforward process. The exact steps vary slightly between iOS and Android, but the principle is the same. First, ensure your device isn’t locked to a specific carrier and check if your device is eSIM-compatible.
For iOS users (like on an iPhone SE): Yoho Mobile makes it incredibly simple. After purchasing your plan, there’s no need to fumble with QR codes. Just open the Yoho Mobile app and tap the “Install” button. Your iPhone will guide you through the final steps in under a minute. You can find more details on Apple’s official dual SIM support page.
For Android users (like on a Google Pixel a-series): The process is also easy. You’ll typically receive a QR code after purchase. Simply go to your phone’s network settings, select “Add eSIM,” and scan the code with your camera. You can also add it manually if needed, as detailed on Google’s Pixel support site.

Frequently Asked Questions (FAQ)
Can I use an eSIM and a physical SIM at the same time on an iPhone SE?
Yes, you absolutely can. The iPhone SE (2nd generation and newer) supports Dual SIM with a nano-SIM and an eSIM. This allows you to have two active lines simultaneously, such as your home number on the physical SIM and a travel data plan on the eSIM.
Will using an eSIM drain my battery faster on a single SIM phone?
Using two lines (one physical, one eSIM) can slightly increase battery consumption compared to using just one, as the phone maintains a connection to two networks. However, the impact is generally minimal and not something most users will notice in daily use. Modern phones are highly optimized for DSDS functionality.
How do I switch between my physical SIM and my eSIM for data?
Switching is simple. On both iOS and Android, you can go into your phone’s Cellular or Mobile Network settings. There, you’ll see both of your plans listed. You can select which line you want to use for mobile data, and you can also set a default line for voice calls and messages.
What happens to my physical SIM when I activate an eSIM on my Pixel a-series?
Nothing happens to your physical SIM. It remains active and functional. After you activate the eSIM on your Google Pixel a-series, your phone will recognize both lines. You can then manage them in your network settings, choosing which one to use for calls, texts, and data, effectively turning your device into a dual SIM phone.
Conclusion
Having a phone with only one physical SIM slot no longer means you’re limited to a single mobile plan. Thanks to the power of embedded SIM technology, you can easily add a second, digital line to your device. This unlocks incredible flexibility for international travel, managing multiple numbers, and ensuring you always have the best connection available.
With Yoho Mobile, activating a second line is not only possible but also simple and affordable. From our risk-free trial to the peace of mind offered by Yoho Care, we make global connectivity accessible to everyone.
