eSIM Installed but No Service Abroad? 12 Fixes, in Order
Your eSIM installed fine, you landed, and the status bar says "No Service". Nine times out of ten it is one of three settings. Here is the checklist to work through, fastest fix first.
This is a different problem from a QR code that will not scan (that one is covered in eSIM QR code not working). Here the profile is installed, the line exists in your settings, and it simply is not connecting.
Work through these in order. The first four solve the overwhelming majority of cases.
1. Is data roaming on for the eSIM line?
This is the number one cause, by a wide margin. A travel eSIM is technically roaming on a foreign network, so with roaming off it will never connect.
- iPhone: Settings → Mobile Data (Cellular) → tap the travel plan → Data Roaming ON
- Android: Settings → Network & internet → SIMs → pick the travel eSIM → Roaming ON
Turn it on for the travel eSIM line only, not for your home SIM. Full explanation in data roaming settings explained.
2. Is the line actually turned on?
Installing a profile does not always enable it.
- iPhone: Settings → Mobile Data → tap the plan → Turn On This Line
- Android: Settings → Network & internet → SIMs → toggle the eSIM to on
3. Is the eSIM set as your data line?
Your phone can have the eSIM enabled but still be trying to use your home SIM for data.
- iPhone: Settings → Mobile Data → Mobile Data → select the travel plan
- Android: Settings → Network & internet → SIMs → Mobile data → select the travel eSIM
See dual SIM abroad for the full three-switch setup.
4. Toggle airplane mode
Thirty seconds on, thirty seconds off. This forces a fresh network scan and fixes a surprising number of "arrived and nothing happened" cases, especially when you switched on your phone while still taxiing.
5. Restart the phone
A full power cycle, not just a lock. After a long flight with the modem asleep, this clears stuck registration states.
6. Wait five minutes
First registration on a foreign network can take a few minutes, particularly at a busy airport where thousands of handsets are all registering at once. If the bars appear and disappear, it is working — just slowly.
7. Select the network manually
If automatic selection fails, pick a network by hand:
- iPhone: Settings → Mobile Data → tap the plan → Network Selection → turn Automatic off → choose a local network from the list
- Android: Settings → Network & internet → SIMs → Automatically select network → off → pick one
Try each listed operator in turn. Your plan works with specific partner networks, so one of them will take you.
8. Check you are in a covered country
Obvious but common. A Thailand plan does not work in Cambodia; a "Europe" plan may not include the UK or Switzerland. Check the plan's country list — see "Europe" eSIM plans explained.
9. Check the plan has actually started
Most travel eSIMs start their validity window on first connection to a network in the destination, not at purchase. But a plan bought weeks ago with a short validity may have expired. Check the remaining balance and validity in your account.
10. Check your data balance
If you have used your allowance, the line stays connected but nothing loads. That looks like a broken eSIM and is not one. How to check your data balance covers where to look.
11. Reset network settings
This clears APNs, saved Wi-Fi networks and VPN configs — a nuclear option that fixes odd cases.
- iPhone: Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings
- Android: Settings → System → Reset options → Reset Wi-Fi, mobile and Bluetooth
It does not delete your eSIM profile. You will have to re-enter Wi-Fi passwords.
12. Check APN settings
Rarely needed — most travel eSIMs configure themselves — but if everything above fails, a manual APN may be required. See eSIM APN settings.
If none of that works
At that point it is not a settings problem. Contact support with three details: your order reference, your phone model and iOS/Android version, and what the status bar says. A provider worth buying from will replace or refund an eSIM that genuinely does not activate — ours is covered by the refund policy.
FAQ
My eSIM worked yesterday and stopped today. Check the balance first, then the validity window. Both look identical to a network fault.
It works on Wi-Fi but not mobile. That means the profile is fine and the cellular connection is not — go back to steps 1 to 3.
I see "SOS" or "Emergency calls only". The phone has found a network but cannot register you on it. Steps 1, 7 and 8 are the relevant ones.
Should I delete and reinstall? No — not before contacting support. Most travel eSIM profiles can only be installed once. Deleting it may destroy it permanently. See should you delete your eSIM after a trip.
The bottom line
Data roaming off, line off, wrong data line, and airplane-mode toggle account for most "no service" reports. Work down the list in order and you will almost certainly be online before step five.
