When dealing with an eSIM issue involving showing no signal, first check the active plan, selected mobile-data line and network registration before changing advanced settings.
Test one reversible step at a time for an eSIM issue involving showing no signal, and keep the installed eSIM profile in place so that useful configuration details are not lost.
If an eSIM issue involving showing no signal persists on NoveSIM, use data.esim only when a manual APN is required and contact support before removing the profile.
Quick answer: Confirm the profile is present and the plan covers the destination, select the travel eSIM for Mobile Data, enable Data Roaming and leave Network Selection on Automatic. Use APN data.esim only when manual entry is required.
Check the live your destination eSIM options, verify the phone on the compatible-device list and review how our service works before purchase.
Identify the Exact Symptom
No profile, No Service, signal without internet and one failing app are different problems. Record the exact status and check coverage, active plan, enabled line, automatic network selection, device compatibility and local outages.
Use a reversible check first: confirm the plan or service requirement, observe the current status and change one setting at a time. This approach is especially important for coverage, active plan, enabled line, automatic network selection, device compatibility and local outages, where replacing the profile or resetting the phone would remove useful diagnostic evidence.
Check Reversible Settings
Switch on the travel line, select it for Mobile Data, keep primary-line roaming off and disable automatic data switching. Test more than one normal website or app.
The decision should account for coverage, active plan, enabled line, automatic network selection, device compatibility and local outages. Check current product and device information at the time of use because network access, hotspot support, 5G, compatibility and retail conditions depend on the selected plan, exact model, region and local coverage.
Refresh Safely
Wait several minutes, toggle Airplane Mode and restart if necessary. Keep the installed eSIM and contact our support team if reversible checks fail.
For your destination, prepare the information that would be hardest to recover during an outage: the route, booking reference, address, support details or device instructions. Offline preparation matters most when the itinerary includes coverage, active plan, enabled line, automatic network selection, device compatibility and local outages.
Confirm the Plan Can Work Here
Check that the plan is active, still valid, has remaining data and includes the present country. A settings change cannot restore an expired allowance or add a country that the plan does not cover.
Use a reversible check first: confirm the plan or service requirement, observe the current status and change one setting at a time. This approach is especially important for coverage, active plan, enabled line, automatic network selection, device compatibility and local outages, where replacing the profile or resetting the phone would remove useful diagnostic evidence.
Check the Active Data Line
Open the phone’s SIM settings and make sure the travel profile is enabled and selected for Mobile Data. Turn off automatic data switching so the result is not confused by the primary SIM.
- Travel eSIM enabled
- Travel eSIM selected for Mobile Data
- Data Roaming on for the travel line
- Primary SIM Data Roaming off
- Network Selection initially Automatic

Check current product and device information at the time of use because network access, hotspot support, 5G, compatibility and retail conditions depend on the selected plan, exact model, region and local coverage.
Refresh Network Registration Safely
Wait several minutes after arrival, toggle Airplane Mode once and restart the phone if necessary. Move outdoors or to another nearby location to separate an indoor coverage issue from a configuration problem.
For your destination, prepare the information that would be hardest to recover during an outage: the route, booking reference, address, support details or device instructions. Offline preparation matters most when the itinerary includes coverage, active plan, enabled line, automatic network selection, device compatibility and local outages.
Check APN Only When Needed
If our instructions or support team require manual APN entry, enter data.esim and leave username and password blank. Do not replace it with the name of a domestic operator or another eSIM provider.

FAQ
Why an esim is showing no signal?
Confirm the profile is present and the plan covers the destination, select the travel eSIM for Mobile Data, enable Data Roaming and leave Network Selection on Automatic. Use APN data.esim only when manual entry is required.
Can I keep my primary SIM enabled for your destination?
Usually yes on a compatible dual-SIM phone. For why an eSIM is showing no signal, select the travel eSIM for data, keep Data Roaming off on the primary line and check the home carrier’s charges for calls, SMS and voicemail.
Which roaming setting applies to why an eSIM is showing no signal?
Enable Data Roaming on the our travel eSIM line when partner-network access in your destination requires it. Keep roaming off on the primary line unless its cost is understood, and disable automatic data switching.
Should I delete the eSIM while checking why an eSIM is showing no signal?
Do not delete the installed eSIM. If you have a connection problem in your destination, check the plan status, the active data line, Data Roaming, network registration and APN first. Remove it only when our support team specifically instructs you to do so.
Final Recommendation
Use this page to answer why an eSIM is showing no signal with the requirements of the actual trip or device, not a generic plan label.
For your destination, confirm compatibility and live product terms, prepare the phone on dependable Wi-Fi and keep information for coverage, active plan, enabled line, automatic network selection, device compatibility and local outages available offline.
For a reliable connection, select our travel eSIM for Mobile Data, enable Data Roaming on that line and preserve the installed profile. If manual our APN entry is required, use data.esim with blank username and password.
