Data roaming is on but there is no internet: how to fix it
The eSIM is installed, roaming is on, and still nothing loads. The five settings that cause it, on iPhone and Android, in the order to check them.
You landed, you turned on data roaming, and the phone still says no internet. This is the most common problem with a travel eSIM, and it is almost never the eSIM itself. It is usually one of five settings, and they take a minute to check.
Go in this order.
1. Is the eSIM the line used for data?
A phone with two lines uses one of them for mobile data, and installing a new eSIM does not change that by itself.
- iPhone: Settings, then Mobile Data (or Cellular). Open Mobile Data at the bottom and pick the travel eSIM. While you are there, turn off "Allow Mobile Data Switching", which can silently move you back to your home line.
- Android: Settings, then Network and internet, then SIMs. Choose the travel eSIM and set it as the one for Mobile data.
2. Is data roaming on for that line, and not for the other?
Data roaming is a setting per line, not for the phone.
- Open the travel eSIM's settings and turn Data Roaming on. A travel eSIM is always roaming, so without this it will never connect.
- Open your home line and turn Data Roaming off, so it cannot run up a bill in the background.
3. Is the line actually turned on?
An eSIM can be installed and switched off at the same time. On iPhone, the line has a "Turn On This Line" toggle. On Android, the SIM has an on and off switch. If you installed it days before the trip, it may have been left off on purpose.
4. Are you on the right network?
At an airport, a phone sometimes locks onto the first network it saw and stays there.
- Turn Airplane mode on for fifteen seconds, then off. This is the fix that works most often.
- If that fails: in the eSIM's settings open Network Selection, turn off Automatic, wait for the list, and choose one of the operators your plan uses. The plan page lists them.
5. Is the APN right?
Most eSIMs configure themselves, but if everything else is correct and there is still no data, the access point may be missing. The eSIM's settings have an APN or Access Point Names field. What goes in it depends on the eSIM, so ask support instead of guessing: a wrong APN breaks a connection that would otherwise work.
Still nothing?
Two checks that rule out the rest:
- Is there data left? A plan can run out sooner than expected. Check the app before blaming the settings.
- Has the plan started? Validity begins when the eSIM first connects to a network at your destination, so a plan bought weeks ago should still be fine, but one bought for last month's trip is not.
If none of this works, write to support with your phone model and a screenshot of the eSIM's settings page. With Wigoo the answer comes from us, not from a chatbot loop.
Quick answers
Why does my home line keep taking over?
On iPhone, "Allow Mobile Data Switching" lets the phone move data back to your main line when it thinks the signal is better. Turn it off while you travel.
Do I have to turn roaming on? Isn't that expensive?
Turning on data roaming for the travel eSIM does not cost anything extra: the plan is prepaid, and the eSIM is foreign by design, so roaming is simply how it works. What costs money is data roaming left on for your home line.
Can I fix this without internet?
Yes, all of the above is in the phone's settings and needs no connection. What does need a connection is installing an eSIM, which is why it is worth doing before you leave.
