You can now find out whether your phone works with eSIM in around 30 seconds, just by tapping through a few screens. Until now you had to dig up a list of supported models and match it against your phone's model number — now you can get to the answer right where you are. We built this improvement because we wanted to take the weight off that very first step, the one that often trips people up while getting ready for a trip.
What's new in this update
We've added a simple compatibility checker to our supported-devices page. Just pick one of three options — iPhone, Android, or "not sure" — and follow along to get a quick read on whether your phone can use eSIM. Even if your model isn't on the list, you can still check, because we also walk you through how to look up the identifier stored on the device itself (the EID). We've kept jargon to a minimum, so following the on-screen steps should take you straight to an answer.
Why we made this change (the background)
Explanations like "eSIM needs a compatible device" and "your phone has to be carrier-unlocked first" can feel like a real hurdle when you're new to this. In practice, most major smartphones from the last few years already support eSIM, and many phones sold today come unlocked or can be unlocked easily. In other words, plenty of people already meet the requirements but are left with a nagging sense of doubt. We built this to cut down both the "effort of checking" and that "vague worry" right there, before you buy.
How this helps you (when you'd use it)
If you find yourself wondering the night before a trip whether your phone will really work, you can open the supported-devices page and get a quick read in a few taps. It's also handy when you want to check the phones of family or travel companions all at once. On top of that, knowing a couple of ways to spot a compatible device yourself can help you choose with more confidence. Below are some simple self-checks that complement the checker's result.
Check whether your phone has an EID
On iPhone, go to Settings → General → About. On most Android phones, open the phone app and dial *#06#. If a long number labeled EID appears, that's a good sign your phone supports eSIM. You don't need to share the number itself with anyone — it's enough to confirm whether it shows up at all.
How to think about carrier locks
Many phones sold in recent years come unlocked from the start. If your phone is older, or you bought it secondhand, you can usually check its lock status through your carrier's account page. Once it's unlocked, setting up an eSIM for travel becomes much more straightforward.
Good to know too: what can you actually do with eSIM?
Just as important as whether your phone is compatible is knowing "what it can do" before you buy. Bloomy eSIMs are data-only. You can't make or receive regular phone calls or send SMS using a phone number, but app-based calls that run over data — WhatsApp, Messenger, FaceTime and the like — work as usual. If most of your everyday communication already happens through apps, that's often all you need. If you do need a phone number or SMS, consider pairing it with another option, such as a local SIM or a plan that includes a number. Keep in mind that connection quality depends on the local network, your device, and the area you're in, and that a fair-use policy applies to data-unlimited plans.
The checker's result is a guide, not a guarantee. For the final word on compatibility, please also check the information from your device's manufacturer (this guidance is current as of June 2026).
What we focused on, the Bloomy way
We chose wording that reassures rather than alarms — language that calmly gets across the fact that "most people can already use this." Instead of "you might not be able to use it," we aimed for "check it and put your mind at ease," and we tuned the result-screen copy and the suggestions for what to read next in that spirit. By being honest that the result is only a guide, we try to avoid both over-promising and unnecessary worry.
What's coming next
We'll keep gradually refining the device information we can check and making the guidance clearer. We'll watch for the spots where readers tend to get stuck and improve things step by step.
