With this update, it's now easier to avoid the common stumble of "I have signal, but I can't get online" once you reach your destination. When an eSIM won't connect abroad, the cause is often the line selection and the data roaming setting. We've reorganized your account page and your purchase email so the steps to check after arrival are easy to find. We've also added a way to post service status on our site if a connectivity issue comes up. The goal is to cut down on the time you might otherwise spend wondering on your own whether it's "something I set wrong" or "a malfunction."
What's new in this update
- Your account page and purchase email now clearly show the two things to check once you arrive:
1. Switch your mobile data to the eSIM line you purchased.
2. Turn on data roaming for that line. - We've added plain-language notes about a symptom you may actually see on location: "If roaming is left off, you may be unable to connect even when a signal is showing."
- We've added a way to share status on our site when something affects connectivity.
Please note that the eSIMs offered by Bloomy are generally data-only — there is no phone number, SMS, or voice calling. If you need calls or text messages, please also look into another option to use alongside it. (Information is current as of June 2026 and is subject to change.)
Why we made this change
Until now, the post-arrival guidance was tucked into the middle of the setup steps and was easy to miss. When you have a signal but still can't get online, not knowing the cause can make it feel like the device is broken. By bringing the two things to check first up front, we wanted to shorten the time spent unsure of what to do. On rare occasions, connectivity can also become unstable because of something on the side of the network providers we work with. With no information shown at those moments, it's easy to assume "this might be a Bloomy problem," so we built a way to let you know what's going on.
What this makes easier: how to troubleshoot when you can't connect
If you're having trouble getting online at your destination, checking the following in order usually helps. In most cases, the first two steps resolve it.
1. Is the right line selected?
Check that your mobile data line is set to the eSIM you purchased. If you have more than one SIM installed, it may still be set to a different line. If your usual home line stays selected, you may be unable to connect abroad — or you could run into unexpected charges — so as a rule, select the eSIM you purchased once you're traveling.
2. Is data roaming on?
For an eSIM used abroad, if data roaming is off you may be unable to connect even when a signal is showing. Turn it on for the eSIM line you purchased. Some people feel uneasy because "roaming" sounds expensive, but here you're turning it on for the eSIM you bought — it's the normal step for using a plan made for travel.
3. Toggle airplane mode / restart
If a setting change doesn't seem to take effect, turning airplane mode on and back off, or restarting your device, can prompt it to reconnect to the local network. This often helps right after you land, or after passing through an area with weak signal while traveling.
4. Have you arrived, and is your device compatible?
Many eSIMs are designed to activate after you arrive at your destination, and your device needs to support eSIM. It's reassuring to confirm the activation timing and compatibility in advance. Keep in mind that connection quality varies with the area, time of day, device, and how busy the local network is. If it feels slow for a while, it may stabilize when you change location or try again later.
Where to check on your device (iPhone / Android)
The exact place to look differs a little by device. Menu names can change between OS versions, so look for the closest matching option.
On iPhone
Go to "Settings" → "Cellular" (or "Mobile Data"), select the line you'll use (the eSIM you purchased), and turn on "Data Roaming" for that line. If you have multiple lines, also check which line "Cellular Data" is set to.
On Android
From "Settings" → "Network & internet" → "SIMs" (or similar), select the eSIM you purchased and turn on "Roaming" and "Mobile data." Names vary by manufacturer and model, so checking the similar-sounding options one by one makes them easier to find.
Good to know: a little prep before you go saves trouble
A small amount of preparation before departure can greatly reduce the worry of not being able to connect. To avoid scrambling after you arrive, we recommend checking the following.
- Confirm that your device supports eSIM before you buy.
- Install your eSIM before you leave (activation timing varies by plan, so check the instructions). This means you're less likely to be stuck even without Wi-Fi at the airport or hotel.
- Make a note of the two steps to check after arrival — "line selection" and "data roaming."
- It also helps to confirm that your device isn't carrier-locked and that your OS is up to date.
We've organized these so you can also review them from your account page after purchase. If you're unsure about the setup, walking through the flow once before departure can help you handle it calmly.
The Bloomy touch
Rather than playing on worry, we chose to show "the two things to check first" prominently and keep the extra details understated. Instead of stacking up technical jargon, we aimed for wording close to the screens you'll actually see on location. For service-status notices, too, we tried to write text that helps you act calmly once you understand the situation — focusing on conveying "what's happening right now and what to do about it."
What's coming next
We'll keep refining the post-arrival guidance and the support paths for when you can't connect, so they're easier to follow. We also plan to gradually improve how we share status, making it easier to find and easier to understand.
