How to Activate an eSIM (Step by Step)

Activating an eSIM takes just a few minutes — there's no card to wait for in the mail and nothing to insert. An eSIM is a digital SIM built into your phone, so you can get connected almost instantly. Here's how to activate one, step by step.

Before you start

Make sure two things are true: your phone supports eSIM (most iPhones from the XS onward and many recent Android flagships do), and your phone is unlocked so it can accept a new carrier. If you're not sure, you can check your phone's compatibility in seconds before you begin.

How to activate an eSIM, step by step

1. Choose a plan and request the eSIM. When you sign up, select the eSIM option. Your carrier sends an activation QR code or a link.
2. Open your phone's settings. On iPhone: Settings → Cellular → Add eSIM. On Android: Settings → Network & internet → SIMs → Add eSIM (wording varies by brand).
3. Scan the QR code your carrier provided, or enter the details manually if prompted.
4. Follow the prompts to download and install the eSIM profile. This takes a minute or two.
5. Set your line preferences — choose the eSIM for calls, texts, and data — and you're connected.

Bringing your own phone? It's the same idea

If you're switching carriers and want to keep your current phone, an eSIM makes it effortless — no need to wait for a SIM card to arrive. As long as your phone is unlocked and eSIM-capable, you can bring your own phone (and your number) and activate the same day. Just choose “keep my number” during signup so your existing number ports over.

Frequently asked questions

How long does eSIM activation take?
Usually just a few minutes. Once you scan the QR code and the profile installs, your line is active — far faster than waiting for a physical SIM in the mail.

Do I need a new phone to use an eSIM?
No. Any eSIM-capable, unlocked phone works. Most iPhones from the XS onward and many recent Android phones support eSIM.

Can I keep my phone number when activating an eSIM?
Yes. Choose the “keep my number” (port-in) option during signup and your existing number transfers to the new eSIM.

What if I lose my eSIM QR code?
Your carrier can resend the activation code or provide it in your account. Because the eSIM is digital, there's no card to lose.
