You've arrived at your destination and added your eSIM, but your Android phone still says "No internet connection." We hear about this from time to time. In most cases, the problem isn't the eSIM itself — it's usually a setting on the phone, such as data roaming being left off or a missing APN (the setting that tells your phone where to connect). Work through the steps in order and you can often solve it on the spot. This article walks through what to check, in order, when an eSIM won't connect on Android — written so it's easy to follow even if it's your first time. (Information current as of June 2026.)

Common reasons an eSIM won't connect on Android
The short version: when data won't work on Android, the cause almost always comes down to one of three things. (1) The line used for data isn't set to the eSIM, (2) data roaming is off, or (3) the APN hasn't been set. Even when the eSIM was issued correctly, data won't start flowing if one of these is missing.
Android in particular has a quirk: even if you add the eSIM from a setup link, the APN may not be filled in automatically. On iPhone the APN is usually applied for you, but on Android it can need to be entered by hand depending on the model and OS version. Knowing this difference ahead of time makes it much easier to stay calm and fix it.
Keep in mind that Bloomy plans are data-only. They don't include a phone number, voice calls, or SMS. However, app-based calls that run over data — WhatsApp, Messenger, FaceTime and similar — work as normal. So it's not that you can't communicate at all; these apps cover your calls and messaging. If you specifically need a phone number or SMS verification, plan ahead — for example by keeping another SIM with a number, or arranging another method before you travel.
Start with the basics (3 steps)
Before touching the APN, check the basic settings below. These alone fix many cases. The exact wording may differ slightly on your model, but the flow is the same.
- Turn on the eSIM line: Settings → Connections (or Network & internet) → SIM manager (SIMs), then enable and select your Bloomy line.
- Set data to the eSIM: Switch the line used for "Mobile data" to your Bloomy eSIM.
- Turn on data roaming: Enable data roaming for the Bloomy eSIM. This is needed to connect to the local network abroad.
Note: leave roaming on your primary everyday line untouched, to avoid unexpected charges.
Once you've done this, toggle airplane mode on and off, or restart the phone. This lets the device reconnect to the network, and connection often kicks in.
Still not connecting? Set up the APN
If data still won't flow after the basic settings, add the APN manually. The APN tells your phone which network to connect to, and the value you enter differs by plan and region.
Your plan's APN value is shown with your purchased eSIM details in your account page. Don't use a generic value from an article — always enter exactly the value shown in your own account page, since it varies from plan to plan.
Here are the steps to add it on Android:
- Open Settings → Connections → Mobile networks → Access Point Names (APN)
- Tap "Add" at the top right
- In the APN field, enter the APN value shown in your account page (you can name it anything, e.g. "Bloomy")
- Save it, then select that APN (mark the radio button)
- Toggle airplane mode off and on, or restart
In most cases, this combination of "turn on data roaming + add the APN" gets data working. When typing, watch for spelling mistakes. The trick is to enter it exactly as shown — including lowercase letters and exact characters.
iPhone vs. Android (do you need an APN?)
Even with the same eSIM, the setup effort differs a little between iPhone and Android. The table below sums up the differences.
| Item | iPhone | Android |
|---|---|---|
| Adding the eSIM | One tap on the setup link | One tap on the setup link |
| APN setup | Usually applied automatically | May need to be done manually |
| Data roaming | Turn it on | Turn it on |
| If it won't connect | Check line selection and roaming | Above, plus check the APN |
If you find yourself thinking "my friend's iPhone worked right away, but only my Android won't connect," it's usually just that the APN isn't entered. It's rarely a broken device or a faulty eSIM, so take a breath and check the APN.
Checklist by situation
Here's what to check, matched to the symptom you're seeing.
| If this happens | Check this first |
|---|---|
| Signal bars show, but only the internet is down | Data roaming on / APN settings |
| Won't pick up a signal / stays out of service | eSIM line on / restart / retry where there's signal |
| Set everything up but nothing happens | Toggle airplane mode off and on, or restart |
| iPhone works but only Android is down | Add the APN manually (value from your account page) |
Testing where there's signal makes the cause easier to find
One thing that's surprisingly easy to overlook: are you actually somewhere the destination network reaches? An eSIM for travel won't connect before you depart, simply because the destination's network isn't available where you are — and that's normal. Many people worry it might be broken, but there's no need to.
The best approach is to finish the setup before you leave, then turn on data roaming and confirm it works once you arrive somewhere with signal (an airport, a city center, etc.). Testing where there's coverage makes it far easier to tell whether you're looking at a settings problem or a signal problem.
If it still won't work
If you've tried everything above and still can't connect, the troubleshooting page covers other possible causes. It's also worth checking the compatible devices page to confirm your phone supports eSIM and is carrier-unlocked. The basic setup steps are also collected in the setup guide. If none of that resolves it, please contact us with your order number. We'll check your eSIM's issuance status and your plan's APN value, and guide you from there.
If you're still choosing a plan for your destination, the eSIM comparison page lets you search by country, data allowance, and number of days. Note that actual connection quality depends on the local network, your device, and the area, and that plans are subject to a fair use policy — be sure to confirm pricing and terms in USD at the time of purchase.
