When dealing with missing text messages while an eSIM is active, first check the active plan, selected mobile-data line and network registration before changing advanced settings.
Test one reversible step at a time for missing text messages while an eSIM is active, and keep the installed eSIM profile in place so that useful configuration details are not lost.
If missing text messages while an eSIM is active persists on NoveSIM, use data.esim only when a manual APN is required and contact support before removing the profile.
Quick answer: Keep the primary number enabled for SMS, use the travel eSIM for mobile data, review iPhone Send & Receive and line labels, and check the home carrier’s roaming availability and charges. Do not delete either eSIM as a first step.
Before purchase, review how NoveSIM works, confirm the exact model on the compatible-device list and choose coverage from the travel eSIM destinations.
1. Your eSIM may be data-only
This is the #1 reason.
Many travel eSIM plans are designed for mobile data only and do not include:
- SMS receiving
- SMS sending
- voice calls
- phone number support
If the plan has no number, it may not receive texts at all.
Fix:
- Check plan details
- Use your main SIM for OTP texts
2. Texts are going to your main SIM instead
If you use dual SIM, your banking and OTP texts usually continue going to the original number on your home SIM.
Users often expect them on the travel eSIM by mistake.
Fix:
- Keep your home SIM active
- Use that line for receiving verification texts

3. Roaming is OFF on the line that receives texts
Your main SIM may need roaming enabled for incoming SMS while abroad, depending on the carrier.
Fix:
- Turn roaming ON for the line receiving OTP texts if required
- Check carrier charges first
4. Weak signal prevents message delivery
SMS can fail in weak coverage zones such as:
- basements
- airports
- rural roads
- mountains
- thick hotel buildings
Fix:
- Move outdoors
- Wait a few minutes
- Restart phone

5. Dual SIM messaging defaults are wrong
Some phones allow separate defaults for:
- Calls
- Texts
- Mobile Data
If the wrong line is selected, outgoing SMS may fail and incoming threads may appear confusing.
Fix:
- Check Messages default line
- Label each SIM clearly
6. OTP texts are delayed by banks or apps
Sometimes the eSIM is blamed, but the real delay is from:
- bank security systems
- spam filtering
- international routing delays
Fix:
- Wait a few minutes
- Request code again once
7. iMessage / RCS confusion
Users sometimes expect internet messaging apps to behave like SMS.
These are different systems:
- SMS = carrier text message
- iMessage = Apple internet service
- RCS = data-based messaging
If data works, iMessage may work even when SMS does not.
8. Recent update changed SIM preferences
Phone updates may reset preferred lines or messaging defaults.
Fix:
- Recheck SIM defaults
- Restart device

Common traveller mistakes
Expecting OTP codes on travel eSIM
Most codes still go to your home number.
Turning off the main SIM completely
This may block bank texts.
Confusing iMessage with SMS
They are different systems.
Ignoring data-only plan limits
Many travel eSIMs have no SMS support.
When to contact support
Contact support if:
- the plan includes SMS but none arrive
- signal is strong and issue continues
- all verification texts fail
- the line recently stopped receiving messages

Final Thoughts
If your eSIM is not receiving text messages, the most common reason is that many travel eSIMs are data-only or your texts are still tied to your home SIM number.
Keep your main SIM active for OTP codes, use the eSIM for data, and verify messaging settings before travel.

Practical Checks before You Rely on This Setup
Keep the primary number enabled for SMS, use the travel eSIM for mobile data, review iPhone Send & Receive and line labels, and check the home carrier’s roaming availability and charges. Do not delete either eSIM as a first step. 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 text messages not arriving while an eSIM is active?
NoveSIM travel eSIM plans are data-only and do not provide traditional SMS or a local number. To receive texts on your usual number, keep the primary SIM enabled where your phone and carrier allow it, while using the travel eSIM for mobile data and keeping home-line data roaming off.
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 text messages not arriving while an eSIM is active.
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.
