Does an eSIM Have a Phone Number? Everything You Need to Know in 2025

eSIMs are changing the way we connect—but one question still puzzles many travelers and digital nomads: “Can an eSIM have a phone number?”

In today’s digital world, physical SIM cards are slowly fading into the past. Whether you’re switching devices, traveling abroad, or just love the convenience of modern tech, eSIMs are the new standard. But that leads to the golden question: do eSIMs come with phone numbers? And how exactly do you find it?

In this guide, we’ll break down everything you need to know about eSIM numbers, how to locate them, how they function, and what to expect when you activate one. And most importantly—we’ll clear up a common myth: not all eSIMs include a phone number. Read on to understand the difference.

What Is an eSIM?

An eSIM (Embedded SIM) is a digital SIM card embedded directly into your smartphone, tablet, or wearable device. Unlike traditional SIM cards, it doesn’t require physical swapping. It allows you to activate a cellular plan without using a physical nano-SIM.

Think of it as a virtual passport to mobile networks.

Benefits of eSIMs:

• No need to switch SIM cards
  
• Easily switch between carriers
  
• Ideal for international travel
  
• Reduces the risk of SIM loss or damage
  

Can an eSIM Have a Phone Number?

Yes, an eSIM can have a phone number—but here’s the catch: not all of them do. Just like with traditional SIMs, your number is assigned by the mobile carrier. If the eSIM plan supports voice and SMS, you’ll typically receive a phone number when you activate the plan.

However, many eSIMs—especially those made for travel—are data-only plans. These do not include a phone number because they’re meant solely for internet access.

So if you’re asking, “Can an eSIM have a phone number?”—the answer is: Yes, but only if the plan supports it.

Do I Get a Phone Number With eSIM?

Sometimes, yes. But not always.

Most mobile carriers provide a phone number when you activate an eSIM plan that includes voice and SMS features. But if you’re using a data-only eSIM (which is very common for travelers), you won’t receive a number for calls and texts—just data access.

Quick Tip:

• If you need a number for local calls/SMS abroad, choose an eSIM plan that includes voice + SMS.
  
• If you’re only using apps like WhatsApp or FaceTime over Wi-Fi or data, a number might not be necessary.

How to Find My eSIM Number

The term “eSIM number” can refer to either:

1. Phone Number assigned to the eSIM (if your plan includes one)
   
2. EID (Embedded Identity Document), the unique identifier for your eSIM
   

Here’s how to locate both:

📱 To Find Your eSIM Phone Number:

• iPhone: Settings > Cellular > Your eSIM > Number
  
• Android: Settings > Network & Internet > Mobile Network > eSIM > Number
  

🔎 To Find Your eSIM EID:

• Go to Settings > About Phone > EID section
  

Pro Tip: Some apps and carriers list your eSIM details in their dashboard upon activation.

Why eSIM Numbers Are Useful

Knowing your eSIM phone number is important for:

• Two-factor authentication (2FA)
  
• Receiving calls/SMS while abroad
  
• Number portability
  
• Setting up WhatsApp or banking apps while traveling
  

But remember: if you’re using a data-only eSIM, these features might not apply. Many apps still work perfectly over Wi-Fi or mobile data without needing a phone number.
