eSIM Setup Is Just a Tap | Bloomys One-Tap Setup Link (QR & Manual Entry Also Supported)

Let's start with the bottom line: Bloomy issues a "one-tap setup link" that opens the eSIM setup screen with a single tap. On a supported device, you simply tap the setup link delivered to your account page after purchase, and the "Add eSIM" screen opens automatically—so you can complete registration without typing in any long codes. Even if the link doesn't open or your device isn't compatible, you can register the exact same profile by scanning a QR code or using manual entry (SM-DP+ address). Whichever method you choose, your connection and its quality afterward are identical. This article breaks down the differences between the one-tap setup link, QR codes, and manual entry—how to use each, and what to do when something doesn't work—in a way that's easy to follow even if it's your first time.

If you'd like to grasp the whole setup flow for using an eSIM abroad first, take a look at our eSIM Setup Guide for Travel (Overview). If you prefer to follow along with the actual screens, the setup instructions page is a handy reference.

What is Bloomy's one-tap setup link (the easiest option)

The one-tap setup link is a link with all the information needed to register your eSIM (the server address and the activation code) already embedded in it. On a supported device, just tapping the link opens the eSIM setup screen automatically, and you complete registration simply by following the prompts. There's no need to display a QR code on a separate screen or type out a long code by hand.

One-tap setup links work on relatively recent smartphones (for iPhone, roughly iOS 17.4 or later is the guideline). If your device isn't compatible, or if tapping the link doesn't open the setup screen, use the QR code or manual entry methods below instead. No matter which entry point you use, the plan and the connection quality are the same.

The differences between the three entry points (one-tap / QR / manual entry)

To use an eSIM, you register line information called an "eSIM profile" on your device. There are three entry points for that registration. The content registered is identical in every case, with no difference in connection quality.

Method	How it works	Best suited for
One-tap setup link	Tapping the link opens the setup screen automatically (almost no input needed)	When you want the easiest option on a supported device
QR code	Scan the issued QR code with your camera	When you can display the QR on a computer, another phone, or paper
Manual entry (SM-DP+)	Type in the SM-DP+ address and activation code as text	When the QR can't be scanned or you only have one device

Which one should you choose?

If you have a supported device, start with the one-tap setup link—it's the simplest. If the link doesn't open or your device isn't compatible, displaying the QR code on a separate screen and scanning it is easy. If the phone you're setting up is the only device you have, if your camera can't scan the code well, or if the QR is small or reflective, manual entry comes in handy. You can pick based on your situation, but whichever you use, your connection and speed afterward are the same.

Things to check before setup

Is your device eSIM-compatible?

Your device needs to support eSIM. If you're unsure whether your model is compatible, it's reassuring to check first using how to check eSIM-compatible devices. A device that is carrier-locked may need to be unlocked.

When to set it up

For many travel eSIMs, the reassuring flow is to "install" the profile at home over Wi-Fi before you depart, then "activate (turn on)" the line after you arrive at your destination. That said, the timing of activation and the conditions for when service begins vary by plan, so always check the guidance provided before and after purchase.

Confirming it's data-only

Like most travel eSIMs, Bloomy is fundamentally data-only. It generally cannot be used for voice calls or SMS (text messages) on a regular phone number. Calls and messages through apps such as WhatsApp can be used where a data connection is available. If you need a phone number or SMS verification, also look into other options (such as a plan that includes a local number, or using it alongside your home line). If phone numbers and SMS are a concern for you, our articles on phone numbers and SMS are a useful reference.

How to use the one-tap setup link

1. Connect to Wi-Fi
2. Tap the setup link delivered to your account page after purchase
3. The "Add eSIM" screen opens automatically—follow the prompts and tap "Continue"
4. Once the download finishes, select it as your mobile data line if needed
5. Activate the line at your destination (turn on data roaming)

* If tapping the link doesn't open the setup screen, your device may not be compatible. In that case, use the QR code or manual entry below.

Setting up with a QR code

The exact wording varies slightly by model and OS version, but the basic flow is the same.

On iPhone

1. Connect to Wi-Fi
2. Open "Settings" → "Cellular" → "Add eSIM"
3. Choose "Use QR Code"
4. Scan the displayed QR code with your camera
5. Follow the prompts to add the plan, and select it as your cellular data line if needed

On Android

1. Connect to Wi-Fi
2. Choose to add an eSIM from "Settings" → "Network & internet" → "SIMs" or similar
3. Scan the QR code
4. Follow the prompts to download and activate

* Menu names may differ by model, appearing as "Mobile network," "Connections," and so on.

Setting up with manual entry (SM-DP+ address)

When the QR code can't be scanned, choose "Enter details manually," "Enter code manually," or similar on the same Add screen.

1. On the Add eSIM screen, choose "Enter manually"
2. Enter the SM-DP+ address
3. Enter the activation code (if required)
4. If prompted for a confirmation code, follow the guidance
5. Once the download finishes, activate the line

To avoid typos, if you can copy and paste the code, pasting it directly is the safer choice. Watch out for uppercase vs. lowercase letters and easily confused characters (0 and O, 1 and l, and so on).

What to do when things don't work

If registration or connection isn't working, don't panic—check the following in order.

1. Reinstall over a stable connection such as Wi-Fi
2. If the one-tap link won't open, try QR or manual entry (and vice versa)
3. Check the SM-DP+ address and code for typos
4. Check that "data roaming" is turned on at your destination
5. Check that your mobile data line is set to the eSIM
6. Restart your device

For detailed steps if that still doesn't resolve it, see our troubleshooting page for connection issues. Note that once an eSIM is deleted, it may not be possible to re-register it with the same QR code or link, so check the guidance before deleting.

The eSIM setup flow with Bloomy

With Bloomy, after purchase you can view your one-tap setup link, QR code, and setup details (SM-DP+ address, etc.) from your account page. Even on devices where the one-tap link isn't supported, the QR code and manual entry information are provided as well, so you can set up in whatever way fits your situation. You can also check your purchased eSIMs and remaining data from your account page.

If you'd like to choose a plan based on your destination and the data volume or number of days you need, you can search by country, data amount, and usage period on our eSIM comparison page. There are also options for those who'd rather not worry about data caps, but unlimited-type plans may come with a fair use policy, speed limits after a certain amount of usage, or tethering conditions, so please check the latest terms before purchasing. Plan details are subject to change. Communication quality varies depending on the local network, your device, and the area.
