Add eSIM on Google Pixel 9: Friendly Setup Walkthrough

So you just unboxed a Google Pixel 9 and you have a trip coming up. Or maybe you are already in a cafe in Lisbon eyeing that roaming alert from your home carrier. An eSIM is your ticket to cheap, local data without swapping plastic cards. And the Pixel 9 makes the whole setup almost boringly easy. Almost. I will walk you through it like the travel buddy who has done this a dozen times.

Before you start

A couple of quick checks will save you from that deep sigh later. First, your Pixel 9 needs to be carrier unlocked. If you bought it directly from Google or paid full price, you are likely fine. If you are on an installment plan through AT&T or T-Mobile, contact them to confirm. Second, you will need a stable Wi-Fi connection during setup. The eSIM profile downloads over the internet, not over the air. Most airports and cafes have that covered.

Also, glance at the eSIM provider's coverage map. All major brands (Airalo, Holafly, Saily, Nomad, aloSIM, Ubigi) support the Pixel 9. But if you are heading to Bhutan or Benin, double-check. The phone itself lists compatible networks once the SIM is installed, so you will know right away.

How to add an eSIM on Pixel 9

There are two common ways to plop an eSIM onto your Pixel 9: scanning a QR code or letting the provider's app do the heavy lifting. Both take under three minutes.

Adding via QR code

If you bought your plan on a website and received a QR code by email, follow these steps:

Open Settings and tap Network & Internet.
Tap SIMs (you might see "Mobile network").
Tap the Add eSIM button at the bottom.
Your phone will launch the camera scanner. Point it at the QR code from your email or booking page.
Once scanned, the Pixel 9 asks you to confirm. Tap Download.
Wait about 30 seconds while the eSIM profile installs. You will see a new SIM card labeled with the provider name.
Now tap the new SIM and make sure Mobile data is toggled on. Also, under Roaming, turn it on if you are outside the eSIM's home country (most travel eSIMs need this).

That is it. Your physical SIM can stay active for calls and texts if you want, while data goes through the eSIM. I will touch on dual SIM tricks later.

Adding via the provider's app

A quicker route is an app like Airalo, Holafly, Saily, or aloSIM. Here is the flow:

Download the app from the Play Store while on Wi-Fi.
Sign up, pick your destination, and choose a plan. For example, a Saily 3GB/30 days USA plan runs about $8.99. An Airalo 5GB Europe package costs around $12.50.
After purchase, tap Install eSIM or Activate. The app will either push the profile directly to your Pixel 9 or show you a manual setup code.
If pushed, accept the prompt and wait. If manual, the app will show an activation code; go to Settings > Network & Internet > SIMs > Add eSIM, then tap "Need help?" and "Enter it manually". Paste the code.
Name the eSIM something memorable like "Portugal eSIM" so you can spot it later.
Toggle mobile data and roaming for that SIM.

The app method is my go-to because you do not need to fumble with a QR code on another screen. Plus, most apps let you top up or buy a new plan without re-downloading the eSIM.

Which eSIM works best on Pixel 9?

All the providers on NomadCue's radar play nicely with the Pixel 9. I tested a few to see what felt right. Here is a quick rundown with 2026 prices:

Airalo: huge country list, solid 5G speeds in most spots. Regional plans like Asia 5GB/30 days cost $8. The app walks you through setup. Good if you want granular data packs.
Holafly: unlimited data plans from $19 for 5 days in Europe. A pick for heavy streamers. No hotspot on some unlimited plans, though, so read the fine print.
Saily: dead simple app, cheap intro prices. One-off 1GB plans start at $3.99, perfect for a weekend. Data packages like 10GB/30 days in Australia for $19.
Nomad: often runs discounts, and their APAC plans (10GB/$13) are a steal. The manual activation code is clear on the confirmation screen.
aloSIM: great if you travel with a buddy. Their data-sharing feature lets you gift a gig to another aloSIM user on the same trip. Plans from $4.50 for 1GB USA.
Ubigi: reliable network routing and 5G in over 25 countries. Their European 3GB/15 days plan runs $9.50.

No one brand rules them all. If you bounce between continents, grab a global or regional plan from Airalo or Nomad. If you stay in one country for a month, Ubigi's monthly plans make sense. Saily is my "I just need maps and WhatsApp" champion.

Common questions

Can I use two eSIMs on the Pixel 9?

Yes. The Pixel 9 supports dual SIM with two active eSIMs at once, or one physical SIM and one eSIM. You can even store several eSIM profiles and toggle between them. Just remember only two can be active simultaneously. If you have a home carrier physical SIM plus a travel eSIM, you are golden.

Does my Pixel 9 need to be unlocked?

Absolutely. A carrier-locked phone will not let you add an eSIM from another provider. You can check in Settings > About phone > SIM status. If you see "SIM locked", contact your carrier to request an unlock. Most U.S. carriers unlock after 40-60 days of service.

Will the eSIM drain my battery faster?

Barely. Having two SIMs active can use a tiny bit more power because the phone pings two networks. But with the Pixel 9's battery, you will not notice a difference in daily use. The eSIM itself is just a digital profile, not extra hardware.

Bottom line

Adding an eSIM on the Google Pixel 9 is as straightforward as ordering a latte. You pick a plan from a solid provider (Airalo, Holafly, Saily, or any on our list), follow the on-screen taps, and land with data ready to go. No plastic, no store visits, and no scary roaming bills. Give yourself five minutes before you fly out, and you will step off the plane already connected.
