How to get an eSIM with phone number?

Here's how to get an eSIM with a phone number to enable calls, SMS, and data on your device to stay connected.

To get an eSIM with a phone number, contact your local carrier, complete ID verification, and request a new number or transfer your existing one. You’ll be able to make calls, send SMS, and use mobile data. For most travelers, a data-only eSIM with WhatsApp calling is simpler and cheaper.

In this guide, we walk you through how to get an eSIM with a phone number, requirements, popular options, and explain why most travellers do just fine with an unlimited data travel eSIM instead.

What is eSIM with a Phone Number?

An eSIM with a phone number is a digital SIM that not only gives you mobile data but also assigns you a local phone number. With this number, you can make and receive calls, send SMS, and complete app or banking verifications that require text messages. Unlike data-only eSIMs, which are mainly for internet access, an eSIM with a phone number works more like a traditional SIM card issued by a local carrier.

Can you get an eSIM with a phone number?

Just like any plan, an eSIM for your home cell phone contract will come with a phone number, unless you opt for a data-only eSIM. You can also easily switch from a physical SIM to an eSIM and keep your number, as long as your phone is eSIM-compatible.

The case for international travel eSIMs is different. Yes, some travel eSIM providers offer a local phone number, like in Holafly Plans‘ Unlimited Plan. This said, it’s not common. Even if you get an eSIM with a phone number, these are often limited to local calls.

Instead, tourists mostly opt for data-only eSIMs. These are a cheaper option, still give you access to VoIP apps like WhatsApp and Telegram, and let you keep your primary phone number for emergencies and authentication.

Why buy an eSIM with a phone number?

There are only a handful of reasons why you’d need an eSIM with a phone number if you are traveling:

You need a local number for traditional calls and SMS. Some situations require an actual phone number: business calls with local clients, appointments with service providers (hotels, restaurants, tours), or banking verification that doesn’t support VoIP apps.
You’re using local services that require local numbers. Certain services, such as food delivery, ride-sharing apps, or rental services, may require a local phone number for verification or customer support.
You cannot use WhatsApp, Telegram, or similar apps for calls. If your contacts don’t have internet-based calling apps, or you’re traveling to areas with limited app adoption, a traditional phone number becomes necessary.

For all other reasons, you can get by with a data-only eSIM, preferably one that offers unlimited data. Moreover, you can get it in minutes, and you don’t have to worry about contracts or working around getting a local address for a contract.

If you still think an eSIM with a phone number is your only solution, here are some options.

Where can you get an eSIM with a phone number?

Here are some carriers that support eSIM in the most popular destinations.

Not all carriers offer eSIMs with a phone number, nor are all plans available for tourists. You should check this information before choosing an operator and prepaid options.

Requirements to buy an eSIM with a phone number

While each provider has its own processes and requirements, most conditions remain the same. Here are some things you can expect:

Local carrier account: You must become a customer of a mobile carrier in that country.
eSIM-compatible device: Your phone must support eSIM technology.
Unlocked phone: Verify your phone is unlocked and works with multiple carriers.
Valid ID: Government-issued identification documents for the country where you’re purchasing.
IMEI number: Your phone’s unique 15-digit identifier. You can find this in Settings > About Phone.
eSIM plan purchase: Select and purchase an eSIM-enabled cellular plan.
Working payment method: Ensure you have a credit or debit card to purchase and activate your plan.

Afterward, you might need to visit an operator branch to become a customer and request your eSIM.

Some companies may offer it online via email or QR code. In some cases, you can install it yourself; in others, you must bring your device to the physical location.
