If your eSIM is not receiving SMS, the cause is usually one of three things: the plan does not include a phone number, the wrong SIM is handling texts, or your phone settings are routing messages to another line.
This is a very common point of confusion, especially with travel eSIMs. Many travelers assume that if mobile data works, SMS should also work. But travel eSIM plans are often data-only, which means internet works while traditional text messages do not.
This guide explains exactly why your eSIM is not receiving SMS, how to tell whether your plan supports texts at all, and what to change on iPhone or Android.
Quick answer: Most travel eSIMs are data-only, so they do not receive standard SMS. If your plan should support texts, check that the correct SIM line is active for messaging, your line is enabled, and your phone has signal on that number.
1. Your travel eSIM may be data-only
This is the most common reason.
Many travel eSIM plans include:
- mobile data
- internet access
- apps like WhatsApp, iMessage, Telegram, FaceTime, and email
But they do not include:
- traditional SMS texting
- local phone number
- normal voice calling
If your eSIM is data-only, not receiving SMS is normal behavior.

2. SMS is going to your main SIM, not the eSIM
If you use dual SIM, your home number may still be the line that receives normal text messages.
This is often the correct setup:
- Main SIM: calls and SMS
- Travel eSIM: mobile data
In this case, the eSIM is not “failing” to receive SMS — your text messages are simply tied to your original number.

3. Your eSIM line has no assigned number for SMS
Some eSIM plans do not provide a number that works for normal text messaging.
So even if the phone shows the eSIM installed and active, SMS reception may still not exist on that line.
This especially matters for:
- verification codes
- bank SMS
- two-factor authentication
- one-time passwords
If you need those, they often continue to arrive on your main SIM number, not the travel eSIM.
4. Your main SIM is turned off
If you expected SMS on your home number, but turned that SIM off completely, texts may stop arriving.
Fix:
- Turn your main SIM back ON
- Leave it active for SMS if needed
- Keep roaming/data usage controlled separately
Many travelers keep the main SIM on for number access, while using the eSIM for data only.
5. The line is enabled, but has no usable signal
To receive standard SMS, the SIM line usually still needs network access.
If your number is active but has:
- no signal
- no roaming support
- line disabled
SMS may not arrive.
Fix:
- Check that the relevant SIM line is ON
- Check it has signal
- Check roaming settings if your home carrier requires roaming for SMS abroad
6. iMessage or chat apps are being confused with SMS
Some users think SMS is failing when actually:
- iMessage is failing
- RCS is failing
- WhatsApp is working but SMS is not
These are different systems.
- SMS: mobile number carrier text
- iMessage: Apple internet messaging
- WhatsApp: internet app messaging
If your eSIM has data, internet messaging apps may still work perfectly even when normal SMS does not.
7. Verification codes are being sent to another number
If a bank, app, or website sends a code, it usually goes to the number already registered on that account.
That is often your original phone number — not the new travel eSIM.
So if the code is not arriving on the eSIM, that may simply mean it was never supposed to.
How to check whether your eSIM supports SMS
Check one of these:
- provider product page
- order confirmation email
- account dashboard

Look for wording like:
- data only
- no voice / no SMS
- includes local number
- calls and texts supported
iPhone fixes
Check which lines are active
- Settings
- Cellular
- Confirm both SIM lines are enabled if needed
Check default line behavior
- See which number is active for calls and messages
- Keep main SIM enabled if you need bank SMS
Check iMessage separately
- Settings
- Apps / Messages
- iMessage settings
Android fixes
Check SIM status
- Settings
- Network & Internet
- SIMs
- Verify the correct line is ON
Check preferred SMS line if supported

If you expected chat features, confirm Google Messages / RCS settings separately from normal SMS.
Fast 60-second checklist
- Check if the eSIM is data-only
- Check whether the SMS should go to your main SIM instead
- Turn the correct SIM line ON
- Check signal on that line
- Restart phone
- Test with a regular SMS from another phone
What to do if you need bank or verification SMS while traveling
The safest setup is often:
- keep main SIM active for number access
- turn off roaming data on main SIM
- use travel eSIM for mobile data
That way, you can still receive:
- OTP codes
- bank alerts
- login confirmations
while using cheaper travel data on the eSIM.
Common traveler mistakes
Assuming all eSIMs include SMS
Many travel eSIMs are data-only.
Turning off the main SIM completely
This can stop bank and verification messages on your usual number.
Confusing WhatsApp or iMessage with SMS
These are different systems.
Expecting verification codes on a new travel number
Most accounts still send them to the old registered number.
When to contact support
Contact support if:
- the provider says the eSIM includes SMS
- the line has signal but receives no texts
- manual SMS testing still fails
- you believe the number assignment is wrong

Final thoughts
If your eSIM is not receiving SMS, the most likely explanation is simple: the plan is data-only or your texts are still tied to your main SIM number.
For most travelers, the best setup is keeping the home SIM available for SMS while using the travel eSIM for data. Once you separate those roles clearly, the confusion usually disappears.
