What to Do If Your eSIM Is Not Working After Installation

If your eSIM is not working after installation, do not delete the profile right away. Deleting an eSIM can make troubleshooting harder, and some profiles may not be reinstallable.

The quick answer: check that the eSIM is selected for mobile data, confirm that you are in the destination covered by the eSIM, follow any data roaming instructions, and restart the device. If it still does not work, collect your order details and contact support.

Quick troubleshooting checklist

Start with the simple checks. They take a few minutes and often solve the issue.

• Confirm that the eSIM profile is installed.
• Check that the eSIM is selected for mobile data.
• Make sure your home SIM is not being used for data by mistake.
• Confirm that you are in the country or region covered by the eSIM.
• Turn on data roaming for the eSIM line if the instructions require it.
• Restart the phone.
• Wait a few minutes after enabling the line.

Check the mobile data line

Your phone may have more than one line: a home SIM and a travel eSIM. If mobile data is still assigned to the home SIM, the eSIM will not provide internet.

Open mobile network settings and check which line is selected for data. The exact menu depends on the device, but the goal is simple: the travel eSIM should be the mobile data line.

Check the destination coverage

A travel eSIM is usually designed for a specific country or region. If you are not yet in the destination, are only on a layover, or chose the wrong region, the connection may not work as expected.

Before contacting support, compare your location and route with the eSIM details. If your trip includes several countries, make sure the eSIM fits that route.

Check data roaming if required

Some eSIM instructions require data roaming to be enabled for the eSIM line. This is not the same as enabling roaming for your home SIM.

Follow the instructions for the eSIM you bought. If data roaming is required, enable it for the travel eSIM line only.

Restart the device

After installing an eSIM and changing mobile data settings, a restart can help the phone reconnect to the network and apply the settings.

After restarting, wait a few minutes and test mobile data with a browser, maps, or messaging app.

When to contact support

Contact support if you have checked settings, are in the covered destination, restarted the phone, and mobile data still does not work.

Prepare:

• order details;
• phone model;
• current country;
• screenshots of eSIM and mobile data settings;
• a short list of what you have already tried.

What not to do

• Do not delete the eSIM immediately.
• Do not buy another eSIM before checking the first one.
• Do not enable data on your home SIM without understanding roaming terms.
• Do not change many settings at once without noting what changed.

Final CTA

If you are preparing for a trip, check phone compatibility and installation instructions before departure. When you are ready, choose a travel eSIM on LocalSIM and keep the order details available.
