eSIMs are shaking things up in the world of mobile connectivity, allowing us to stay connected wherever we are, but they can leave us with a few questions too. One of the most common ones is: Do eSIMs come with phone numbers? And the answer is both yes and no. This gray area is exactly why so many travelers find eSIMs confusing. In this article, we clear things up so you know exactly what to expect when buying an eSIM from Airalo.

What's an eSIM?

An eSIM is like a SIM card, but it's a digital version, and the functionality is already built into your device. To use an eSIM, you have to purchase an eSIM and then activate it. You can download the Airalo app (App Store | Google Play Store) and buy your eSIM directly on the app. Doing this means you don't need to scramble to buy a physical SIM card when you travel, and you can get instant access to local data services without the hassle.

Do eSIMs come with phone numbers?

Data/Calls/Texts eSIMs come with a phone number, while Data-only eSIMs don’t. Here are eSIMs from Airalo that come with phone numbers:

Do You Keep Your Phone Number When You Install an eSIM?

Yes, installing an eSIM does not change or remove your existing phone number. An eSIM simply adds a cellular line to your device (like having two SIMs). After installation, you can choose which line you use for calls, texts, and mobile data in your phone settings.

If your eSIM is data-only, you can keep your primary SIM/eSIM enabled, so you can still receive calls and SMS on your usual number while using the eSIM for data.

If your eSIM includes calls and texts, it comes with a new phone number from the eSIM. You can choose to use that line for calls/texts instead, but your original number stays on your device unless you remove it.

Note: If you keep your primary line enabled for calls and texts while abroad, roaming charges may still apply, including possible data fees, depending on your carrier's policies. To avoid unexpected charges, make sure Data Roaming is disabled for your primary line, or disable your primary line altogether. You can turn it back on when you return from your trip. If you are unsure, check with your carrier to confirm whether they charge for calls, texts, or roaming services while abroad.

How Do I Check if My eSIM Is Data-Only?

To check what an eSIM offers before purchase, look for a toggle at the top of the eSIM page that lets you alternate between Data and Data/Calls/Texts. If you don't see a Data/Calls/Texts option, the eSIM is data-only. You can still use internet-based calls and messages with a data-only eSIM, with apps like WhatsApp.

Some eSIMs will also have another toggle right under the Data toggle, letting you select a Standard or Unlimited eSIM. Unlimited eSIMs give you unlimited mobile data in a specific country or region, for a fixed period of time.

Can I Continue Using My Phone Number Even With a Data-Only Plan?

You can continue to use your phone number while using the data from your eSIM as long as your phone has dual SIM technology. This way, you can keep receiving calls and messages from your home line while connecting with your eSIM data plan.

However, remember that using your primary number abroad can result in unexpected roaming charges.

Other Ways to Stay Connected Without a Phone Number

A good alternative to avoid roaming fees while still being able to call and message your friends is to use internet-based calling apps like WhatsApp or FaceTime while using a data-only eSIM. You can also use social media apps such as Messenger or Instagram.

You now better understand whether eSIMs come with a phone number, so you are ready to make an informed decision when you next travel. Choose the right plan for you, stay connected, and avoid roaming fees.
