Can I receive phone calls on my primary number?

Yes, you can receive phone calls on your primary number even when using an eSIM. This is possible if your device supports having both a SIM and an eSIM activated at the same time. Many modern smartphones come with Dual SIM Dual Standby (DSDS) technology, which allows both physical SIM and eSIM.

However, the capability to have multiple eSIMs active at the same time varies depending on your device model. For instance, certain iPhone models like the iPhone 13 series allow you to use Dual SIM with either two active eSIMs or a combination of a nano-SIM and an eSIM. In contrast, older models like the iPhone 12, iPhone 11, iPhone XS, iPhone XS Max, and iPhone XR support Dual SIM with a nano-SIM and an eSIM, but only one eSIM can be active at a time.

How to set up Dual SIM with eSIM for calls and data on iPhone 

Setting up and using Dual SIM with eSIM on your iPhone for calls and data is a straightforward process. This feature is especially useful if you want to maintain two different phone numbers, such as one for personal use and another for work, or if you're traveling abroad and need a local number.

Scanning a QR Code or Using a Carrier App

1. Obtain the QR Code: Once you buy your eSIM, eSIM Card will give you a QR code. Look for this in your account under 'My eSIMs.'
2. Access iPhone Settings: Navigate to 'Settings' on your iPhone, tap 'Cellular,' and choose 'Add Cellular Plan.'
3. QR Code Scanning: Select 'Use QR Code' and then scan the code eSIM Card has given you.
4. Finish Setup: Name your new eSIM and adjust settings for calls, texts, and data as you prefer.

Remember, having carrier support for eSIM is key. Not every carrier provides eSIM services, so check with your provider.

Entering eSIM Information Manually

If necessary, enter eSIM details manually. Contact your carrier for these details.

1. Go to Settings > Cellular or Mobile Data > Add Cellular Plan > Enter Details Manually.

For the most comprehensive and detailed instructions, please refer to the eSIM Card Support page. 

Dual SIM on iPhone 13 (and beyond!):

• Gather: iPhone 13 (+ eSIM details, physical SIM if applicable)
• Launch: Insert SIMs, power on iPhone, check carrier eSIM prep (if needed)
• Settings: Cellular/Mobile Service > Add eSIM (eSIM activation)
• Choose Champions: Mobile Data + Lines (Calls/Texts) for each SIM/eSIM
• Label It (Optional): Customize names for each line in "Lines"

Using two SIMs can drain your battery faster. Keep your charger handy.

Bonus: Explore "Cellular Data Switching" for automatic data usage between lines!

Note: Specific steps may vary slightly depending on carrier and iPhone model.

Note: If you face any issues, restart your phone or Seek help from eSIM Card.

Limitations of Using Your Primary Number with an eSIM

When using an eSIM alongside your primary SIM card, there are a few limitations you should be aware of. These limitations can affect how you use your phone for calls and data. Here's what you need to know:

Call Forwarding Between eSIM and SIM Lines

Not all phones support using a SIM and an eSIM at the same time. This feature, known as Dual SIM Dual Standby (DSDS), is available on certain smartphone models. If your phone supports DSDS, you can stay connected with both your physical SIM and eSIM simultaneously. However, the number of active eSIMs varies depending on the phone model.

For iPhones, models like the iPhone 13 series can use two active eSIMs or a combination of a nano-SIM and an eSIM. Older models like the iPhone 12, 11, XS, XS Max, and XR support a nano-SIM and an eSIM, but only one eSIM can be active at a time.

Data Usage Tracking for Each Line

Keeping track of data usage for each line (SIM and eSIM) can be challenging. It's important to monitor your data usage, especially when traveling, as data roaming charges may apply. Your phone's settings should allow you to see data usage for each line, but this can vary depending on the phone model and operating system.

Additional Charges and Roaming

Be aware of potential extra charges when using your eSIM, especially for data roaming. Charges depend on your carrier and the country you are in. It's advisable to check with your carrier about any additional fees for using data roaming services on your eSIM. While eSIMs offer the convenience of maintaining your primary number and accessing data services simultaneously, it's important to be aware of these limitations.
