When your screen sits on "Activating" and won't move during eSIM setup, it's natural to worry: "What if it just won't work?" That feeling is even stronger right before a trip or the moment you land somewhere new, when even a few minutes can feel like forever. But take a breath. In most cases this isn't a broken device — it comes down to your connection, the order you do things in, and the timing of activation, and a few simple checks usually clear it up.
- A stuck "Activating" screen is usually a connection or settings issue, not a fault
- Start with a stable Wi-Fi connection, then restart the device, then wait a few minutes
- Check your data line assignment, data roaming, and device/SIM-lock compatibility
- Activation timing varies by plan, so always confirm it in your purchase details
- These are data-only plans (no phone number, calls, or SMS), but app-based calls like WhatsApp can still work over data
Let's start with the bottom line. 1) Connect to stable Wi-Fi → 2) Restart your device → 3) Wait a few minutes, then check the screen again. These three steps resolve it in many cases. If it's still stuck, work through device compatibility, line settings, and activation timing one by one. This article walks through what's happening, why, and what to do, in an order that anyone can follow without panic — so by trying each step from the top, you can pinpoint where things are getting stuck on your own.

What's actually happening when it's stuck on "Activating"?
"Activation" is the process of loading your eSIM details onto your device and registering it on the carrier's network so it's ready to use. Instead of inserting a physical SIM card, an eSIM handles this registration over the internet. That's why an internet connection is essential for activation. If your connection is unstable, or if the exchange with the server takes a while, the screen can get stuck on "Activating."
In other words, this is usually not a device fault, but a temporary connection delay or processing wait. It's more likely to happen in places with a weak signal, on a crowded Wi-Fi network, or right after you arrive somewhere new when the connection hasn't settled. Rather than reinstalling over and over in a hurry, the fastest path to a fix is to calmly sort out your connection first.
Keep in mind that because an eSIM works through an exchange between your device and the network — from setup all the way to network registration — the time it takes can range from a few dozen seconds to a few minutes. Just knowing that "it may move along if you give it a moment" can take a lot of the worry away.
Basic fixes to try first (in this order)
Before getting into detailed troubleshooting, try the quick, high-impact steps first. After each one, check whether the screen has moved on. If you change several things at once, you won't know what actually worked.
1. Connect to stable Wi-Fi
Activation needs an internet connection. Rather than a crowded hotel or café network, reconnect to the most stable connection you can find. If the signal bars are low or pages load slowly, switching to a different Wi-Fi network can help. If you haven't left yet, the safest option is to complete the installation on your home Wi-Fi before you go.
2. Restart your device
Simply turning the device off and back on often gets a stalled process moving again, because it resets connection tasks that were stuck running in the background. It's quick to do and one of the most worthwhile first steps, and it tends to help with all kinds of issues.
3. Wait a few minutes, then toggle airplane mode on and off
Sometimes network registration is just taking time. Wait about one to three minutes, then turn airplane mode on, leave it for a few seconds, and turn it back off — this can prompt the device to grab the connection again. It disconnects and reconnects the signal, which can encourage registration to retry.
4. Don't reinstall the same eSIM repeatedly
Avoid scanning the same QR code over and over just because it isn't working. Doing so can lead to duplicate registrations that make the situation harder to read, or leave duplicate profiles that are tricky to clean up. Only reinstall after you've identified the cause, and only when it's actually needed.
Causes and fixes by situation
If the basic steps don't help, start from the situation that matches yours. Finding your "when this happens" in the table below makes it easier to guess the cause and the fix.
| When this happens | Possible cause | What to do |
|---|---|---|
| No Wi-Fi / unstable connection | Registration can't complete | Connect to a stable network. Set it up at home before you travel |
| Stuck on "Activating" for a long time | Processing wait or network congestion | Restart → wait a few minutes → toggle airplane mode. Give it time and check again |
| Older device / not unlocked | No eSIM support or SIM lock | Check device compatibility and unlock status (see below) |
| Tried to activate before arriving | Activation timing varies by plan | Check the activation steps and timing in your purchase details |
| Line (primary/data) settings not finished | Mobile data not assigned | Set the eSIM as your "mobile data" line in settings and turn on data roaming |
If more than one applies, checking them one at a time from the top makes it easier to isolate the issue. "Is the Wi-Fi stable?" and "Is the device compatible?" in particular tend to be prerequisites for the other checks.
Check your line and data settings
Even if activation itself has finished, your connection won't start if the line isn't assigned — which can make it look like "nothing has happened yet." Check these three points.
- Mobile data line: Make sure the eSIM you added is selected as the line for data. On devices with multiple lines, a different line may be selected.
- Data roaming: When using a network abroad, this often needs to be on (follow your plan's instructions). If it's left off while traveling, your connection may not start.
- APN (access point): If instructions are provided, enter them exactly as specified. A typo can prevent the connection from working.
The exact steps differ slightly from device to device. Checking the setup guide for your specific model helps you move through it without getting lost.
Check your device and timing
Device compatibility and SIM lock
Activation won't proceed on a device that doesn't support eSIM in the first place, or on a device that's SIM-locked. You can confirm whether your model supports eSIM with our device compatibility check. Used or older devices may not be supported, so checking before you buy is the surest way to avoid surprises. If your device is SIM-locked, you may need to complete an unlock procedure with your current carrier.
Activation timing varies by plan
Many eSIMs follow a flow where you "just install before departure, then activate (turn the line on) after you arrive," while others begin their validity period right after purchase. Getting the timing wrong makes it easy to feel like "it's not connecting = it's stuck," so always confirm the activation steps and start timing in your purchase details. Plan terms and conditions of use may change, so checking the latest information on display gives you peace of mind (as of June 2026).
Last resorts if it still won't move
If "Activating" still won't clear after everything above, consider the following steps. Rather than deleting anything in a hurry, it's best to try these in order.
- Give it some time: The network side can be congested. Try again after changing your location or the time of day.
- Recheck your purchase info and QR code: You can view your installed eSIMs and QR codes from My Account. Double-check that the registered details are correct.
- Contact support: Reach out via our contact page with the details (device, OS, the screen you're seeing, and what you've already tried). Depending on the situation, we may be able to help with options like reissuing. Checking with us before deleting the eSIM on your own can save you the trouble of starting over.
Common questions are also collected in our FAQ. Reading through it first may help you resolve things on your own.
Preparing ahead so activation doesn't stall
Many issues can be prevented with a little preparation before you leave. To avoid scrambling once you arrive, these steps help.
- Complete the installation on stable home Wi-Fi before departure
- Check in advance whether your device is compatible and whether it needs a SIM unlock
- Confirm the activation timing (turn it on after arrival, or right after purchase) in your details
- Skim through the setup steps in the setup guide so you won't be confused on location
Note that Bloomy plans are generally data-only. If you need a phone number, SMS, or voice calls, it's wise to also look into other options such as a local SIM or a plan that includes a number. App-based calls like WhatsApp can work where data is available. If you expect to need a phone number for things like SMS verification, lining up an alternative before you travel will help you avoid getting stuck.

For eSIM basics and other troubleshooting, take a look at our eSIM guide list. If you have a long stay or watch a lot of video, reviewing the terms of use and considering an unlimited plan is one option worth exploring.
Summary
A screen stuck on "Activating" is usually not a device fault, but a matter of your connection, the order of your settings, and activation timing. Start with stable Wi-Fi → restart → wait a few minutes, in order. Next, check your line settings, device compatibility, and activation timing — and if it still won't move, don't force-delete the eSIM; reach out to support. Completing the installation and device compatibility check before you depart means you won't have to scramble once you arrive. As a next step, review the steps for your specific model in the setup guide.
