Here's the short version: setting up an eSIM on Android comes down to three steps — (1) check that your device supports eSIM, (2) add the profile over Wi-Fi (usually by scanning a QR code), and (3) turn the line on once you arrive at your destination. For most phones, the smoothest approach is to add the profile before you leave and switch on data only after you land. This guide walks through the setup flow that's common to Android devices like Pixel, Galaxy, Xperia, and AQUOS, in plain language for first-timers. We've also gathered the spots where people tend to get stuck, plus what to do if you can't get connected.
Getting Started: The Big Picture of eSIM Setup on Android
An eSIM works by writing your plan's details onto a chip built into the phone itself. There's no physical card to swap in and out — you add everything right on screen. On Android, the exact names of the settings screens ("SIM," "Mobile network," "Connections," and so on) vary a little by manufacturer and OS version, but the overall flow is much the same on every device.
If this is your first time, it helps to glance through our setup guide beforehand so you know what the screens look like and won't feel rushed on the day. If you're not sure whether your phone supports eSIM, it's worth checking our eSIM-compatible devices page first.
What to Check Before You Begin
1. Does your device support eSIM?
Not every Android phone supports eSIM. Many newer Pixel, Galaxy, Xperia, and AQUOS models do, but even within the same series it can depend on the model and the country where it was sold. A good sign is finding an option like "Add SIM" or "Download eSIM" under "Network & internet" or "SIM" in your settings. For details, see our compatible devices page.
2. Is your device carrier-unlocked?
A phone bought from a carrier may be locked, which can prevent it from using another provider's eSIM. If you're using a second-hand device, it's a good idea to confirm the lock status with the seller or the carrier first.
3. Understand that it's data-only
Bloomy eSIM is a data-only service. You can use it for the internet, maps, and app-based communication such as WhatsApp, but it does not include a phone number, so it can't make voice calls or send and receive SMS text messages. If you rely on voice calls or on SMS verification codes for banking and other services, consider pairing it with a local SIM or a plan that includes a number. For more on numbers and SMS, this explainer is a helpful read.
The eSIM Setup Steps (Common to Android)
Now for the actual setup. Be sure to do this on a stable Wi-Fi connection (at home, for example), since downloading the profile requires an internet connection.
- Open the Settings app and tap "Network & internet" or "Connections."
- Open an item like "SIM" or "Mobile network," then tap "Add SIM" or the "+" button.
- Choose "Download a new eSIM" and use the camera to scan the QR code provided with your purchase.
- If the QR code won't work, choose "Enter manually" and type in the details provided (such as the SM-DP+ address).
- The profile will start downloading, and once it finishes, your eSIM is added.
The exact screen names and locations for each model are covered, with screenshots, in our setup guide — open it if what you see looks different and you're not sure where to go.
Where to Find It by Manufacturer (For Reference)
| Manufacturer (example) | One possible path |
|---|---|
| Google Pixel | Settings → "Network & internet" → "SIM" → "Download SIM" |
| Galaxy (Samsung) | Settings → "Connections" → "SIM manager" → "Add eSIM" |
| Xperia / AQUOS | Settings → "Network & internet" → "SIM" → "Add SIM" |
*Item names and locations can change with the OS version or the device's release date. If you can't find it, typing "eSIM" into the search box in Settings usually helps you locate it.
When Should You Set It Up? Thinking About Timing
In most cases, the smoothest approach is to add the eSIM profile over Wi-Fi before you leave, then switch on mobile data (the line) only after you arrive. It helps to think of adding the profile and "activating" the line — actually starting to use it — as two separate actions.
That said, the timing of activation and how the start date is counted can differ from plan to plan. To avoid any last-minute scramble before departure, we recommend checking each plan's details for when it becomes usable before you buy.
Once You Arrive: Switching the Line On
After you arrive, switch over like this:
- Open Settings → "SIM" or "Mobile network."
- Select the eSIM you added (your Bloomy plan) and turn on "Mobile data."
- Turn on "Data roaming" (it's often required for international plans).
- If you'd rather avoid unexpected data use from your home line, turning off mobile data on that line can give you peace of mind.
Once you've switched over, you'll see the signal bars at the top of the screen — if a page opens in your browser, you're connected.
Can't Connect? A Checklist
If you've set everything up but still can't get online, don't panic — work through these points in order.
- Is the eSIM you added set as "enabled" and selected for mobile data?
- Is data roaming turned on?
- Do your APN (access point name) settings match the instructions provided?
- Try toggling Airplane mode off and on, and try restarting the device.
- Right after you arrive, it can take a few minutes for the device to pick up a network.

A Note on Choosing an Unlimited Plan
For long stays or for people who watch a lot of video, an unlimited-style plan can be an appealing option, since you don't have to keep an eye on your data allowance. Keep in mind, though, that "unlimited" doesn't necessarily mean full speed no matter how much you use. Speeds may be reduced after a certain amount of usage, and details like the fair use policy and whether tethering (sharing to other devices) is allowed can vary from plan to plan. It's worth checking the terms before you buy so you know what to expect. For details, see our unlimited plans page. As always, real-world speeds depend on the local network, your device, and the area you're in.
What You Can Do with Bloomy, and How to Find a Plan
Once the setup flow makes sense to you, all that's left is choosing a plan that fits your destination. From our eSIM comparison page, you can search by country, data allowance, and number of days. After buying, you can view your QR code and remaining data in My Account, so you can calmly double-check things if you hit a snag during setup. Even if it's your first time, it's designed so you can pick just what you need and prepare without any hassle.
