Does Apple Watch Have Its Own Phone Number?

Have you ever wondered how your Apple Watch receives calls and notifications while you’re far from your phone? Or maybe you’ve come across a “cellular” version of the Apple Watch!

Well, you must be wondering, does Apple Watch have its own phone number?

The answer is no. While some versions of the Apple Watch have a cellular option, they don’t have an actual SIM card. Instead, these versions of the Apple Watch have an eSIM, which allows your Apple Watch to have a cellular connection.

In today’s article, we’ll explain everything you need to know about the eSIM inside your Apple Watch. Let’s dive in.

Does Apple Watch Have a SIM Card?

The Apple Watch has an eSIM card, which is a built-in SIM card. Unlike the regular, plastic SIM card, you can’t remove the eSIM from your Apple Watch.

Apple used this technology to provide network connections for Apple Watches. Unlike the old SIM cards, the eSIM doesn’t take up a lot of space in your device. So, no SIM card door, no big plastic SIM card, just a tiny chip that does the same job.

Why Does Apple Watch Contain an eSIM Card?

The eSIM in your Apple Watch provides a cellular connection to your watch so that you don’t have to carry around your phone all the time. Think of it as a portable Wi-Fi connection or a second phone that has your number.

The eSIM allows you to make calls, reply to messages, stream music, and receive notifications without being in the same room as your phone

However, when you use your Apple Watch to send or receive calls and messages, it takes on the identity of your phone.

In other words, if you call someone using your Apple Watch, your regular number will appear on their screen.

Typically, your Apple Watch receives calls, messages, and other forms of data-related services through a connection with the paired phone or a Wi-Fi connection. 

When none of these options are available, your Apple Watch will use its cellular connection to receive data-related services.

Do All Carriers Support the Apple Watch eSIM?

The eSIM in your Apple Watch is built in, so it must be optimized for the service provider in your country.

Unfortunately, the Apple Watch eSIM isn’t supported in all countries. Additionally, each version of the Apple Watch is optimized to be used in the country of purchase only with a carrier that supports Apple Watch eSIM. 

To make sure this feature is available in your country, you can check the list of countries and carriers that support the eSIM cellular feature on Apple’s website.

Frequently Asked Questions

Do you have to activate the eSIM cellular feature on Apple Watch?

If you have an Apple Watch with an eSIM, you’re not obligated to activate the feature. You can connect your Apple Watch to your iPhone, and you’ll be able to enjoy all the features.

However, your phone needs to be nearby at all times. If you lose connection to your phone, you won’t be able to receive calls, texts, or any data-related services.

Can you make calls using the eSIM in your Apple Watch?

Yes, you can make calls with your Apple Watch. It will take on the identity of your original phone number and process the call just as you’re calling from your phone.

How much does Apple Watch’s cellular service cost?

The cellular service plan costs around $10 each month on average in the US

One thing worth mentioning is that this service comes with the watch. So, you won’t be able to activate the cellular services on an Apple Watch model that doesn’t support it.


Does Apple Watch have its own phone number? While the Apple Watch has a built-in eSIM, it doesn’t have its own phone number. The eSIM is used to provide a cellular connection to your watch when your phone isn’t nearby.

So, you’ll still be able to make calls, reply to messages, stream music, and receive notifications without being anywhere near your phone.
