When dealing with an eSIM hotspot that is not working, 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 hotspot that is not working, and keep the installed eSIM profile in place so that useful configuration details are not lost.
If an eSIM hotspot that is not working persists on NoveSIM, use data.esim only when a manual APN is required and contact support before removing the profile.
Quick answer: Check plan tethering support, select the eSIM for mobile data, enable roaming on that line, turn on the iPhone or Android hotspot and reconnect the second device. Use data.esim only if a manual NoveSIM APN is required.
Before purchase, review how NoveSIM works, confirm the exact model on the compatible-device list and choose coverage from the travel eSIM destinations.
Does an eSIM Support Hotspot?
This is the most common reason.
If the eSIM has no working internet on the phone itself, hotspot cannot share it.
Fix:
- Open Safari / Chrome
- Test normal mobile data first
- Fix data connection before hotspot

Check Whether Your Plan Allows Tethering
Some travel eSIM plans allow data use on the phone but limit:
- hotspot sharing
- tethering
- high-volume sharing
Fix:
- Check provider plan terms
- Look for hotspot or tethering policy
Check the APN
Some carriers require a hotspot APN or correct default APN for tethering to work.
Fix:
- Open APN settings
- Enter provider values exactly
- Restart phone
Select the eSIM for Mobile Data
On dual SIM devices, your main SIM may still be selected for mobile data while trying to hotspot from the eSIM.
Fix:
- Select the eSIM as preferred data line

Fix a Connected Device With No Internet
The laptop/tablet may have cached an old session.
Fix:
- Forget the Wi-Fi network
- Reconnect again
- Re-enter password
Check Battery-Saving Settings
Some phones reduce hotspot functionality in low power modes.
Fix:
- Disable Low Power Mode
- Disable Battery Saver
7. VPN blocks tethering traffic
VPN apps sometimes work on the phone but block hotspot traffic for connected devices.
Fix:
- Disable VPN temporarily
- Retest hotspot
8. Roaming is OFF
Many travel eSIMs need roaming ON for mobile data, including hotspot use.
Fix:
- Select the eSIM
- Turn Data Roaming ON

Common traveller mistakes
Trying hotspot before testing data
Hotspot depends on working data first.
Ignoring plan hotspot rules
Some plans restrict tethering.
Using wrong data SIM
Common dual SIM issue.
Leaving battery saver ON
Can reduce hotspot reliability.
When to contact support
Contact support if:
- data works on phone but hotspot never works
- plan should allow tethering
- APN/settings are correct
- multiple devices cannot connect properly

Final thoughts
If your eSIM hotspot is not working, the eSIM usually is not broken. Most cases come from plan limits, APN settings, wrong data SIM selection, or connected device issues.
Start by testing data on the phone itself, then fix tethering settings step by step.

Turn Off Data Saver or Low Data Mode
Low Data Mode on iPhone and Data Saver on Android can restrict background sharing and connected-device activity. Temporarily disable the relevant control while testing the hotspot, then monitor usage carefully. Menu wording varies by device and software version.
Hotspot Works but Is Slow
Move to a stronger-signal location, stop large background transfers and disconnect unused devices. Hotspot speed depends on the plan, phone, radio technology, partner network, congestion and coverage. Do not force 5G when a stable automatic 4G connection performs better.
How Much Data Does Hotspot Use?
Tethered laptops can download updates, synchronise cloud folders and stream at desktop quality, consuming gigabytes quickly. Mark the connection as metered where possible, pause backup and updates and watch plan usage. Hotspot does not create extra data; every connected device shares the eSIM allowance.
Practical Checks before You Rely on This Setup
Check plan tethering support, select the eSIM for mobile data, enable roaming on that line, turn on the iPhone or Android hotspot and reconnect the second device. Use data.esim only if a manual NoveSIM APN is required. Complete the relevant checks before a flight, border crossing or other time-sensitive moment. Keep offline copies of tickets, accommodation details, directions and support information so that one connection problem does not block the journey.
Check the exact phone model, software version and current plan terms rather than relying on a product-family name or an old screenshot. Device menus, plan inclusions and network behaviour can change. Where mobile data is involved, label the travel and primary lines clearly, keep automatic data switching off when avoiding home-carrier roaming is important, and test with Wi-Fi disabled.
Common Mistakes to Avoid
- Changing several settings simultaneously and then being unable to identify which change mattered.
- Assuming that signal bars guarantee working internet, hotspot access or a particular speed.
- Using an unverified APN, network name, price, compatibility claim or airport portal.
- Sharing a QR code, activation string, account screenshot or other private order information.
- Allowing the primary SIM to switch on roaming data without checking the home carrier’s charges.
When troubleshooting, begin with reversible steps and preserve the installed eSIM. Toggle Airplane Mode, restart the device and recheck the selected line before considering advanced changes. Do not remove an installed profile unless NoveSIM Support specifically instructs you to do so, because an activation code may be intended for one installation.
What Information Helps NoveSIM Support?
Provide the order number, exact handset model, operating-system version, current country and city, the stage that failed and screenshots of the relevant settings. Hide the QR code, activation details, email address and unrelated personal information. A precise description such as “profile installed, network registered, but no data with Wi-Fi off” is more useful than saying only that the eSIM does not work.
Support can then distinguish purchase, installation, activation, allowance, network registration and device-setting issues. Keep the profile installed while the case is checked. If a home carrier, airport, app or local network controls the affected feature, contact that organisation as well rather than assuming the travel eSIM controls every part of the service.

FAQ
What is the quick answer about an eSIM hotspot that is not working?
Confirm that mobile data works on the phone before testing tethering, then check that the selected plan permits hotspot use. Select the travel eSIM for data, enable roaming on that line, restart both devices and use data.esim only when a manual APN is required.
Do NoveSIM plans include a local phone number or SMS?
No. NoveSIM travel plans are data-only and do not provide a local number, traditional calls or SMS. Internet communication apps can use the mobile-data connection where available.
Should Data Roaming be enabled?
Most travel eSIMs require Data Roaming on the travel line. Keep roaming off on the primary SIM and disable automatic mobile-data switching if avoiding home-carrier data charges is the goal.
Should I delete an eSIM when something does not work?
No. Do not delete an installed eSIM unless NoveSIM Support explicitly instructs you to do so. Some activation codes are intended for one installation and may not be reusable.
Final Recommendation
Confirm phone compatibility, unlocked status, exact country coverage, validity and allowance before relying on an eSIM hotspot that is not working.
Install over reliable Wi-Fi, keep the activation details private and use the travel eSIM for mobile data with roaming enabled only on that line when required.
Keep offline travel essentials and work through reversible checks before contacting support. This protects the installed profile and provides a safer route to reliable mobile data.
