If your eSIM works but photos will not send, first identify how the photo is being sent. WhatsApp, iMessage, RCS and other internet services use data, while MMS can depend on the carrier line that owns your phone number.
A successful website test proves that mobile data works; it does not prove that the messaging app has photo permission, enough device storage or a valid MMS service.
NoveSIM travel eSIMs are data-only. We do not provide a telephone number, conventional SMS or MMS, so carrier photo messages may still need your primary line and its home-carrier service.
Quick answer: Test a small photo in a data-based app first. If that works, the eSIM connection is functioning and the failure is likely specific to MMS, the original app, permissions or attachment size.
Is the Photo Using Data or MMS?
| Method | What it needs | First check |
|---|---|---|
| WhatsApp or similar app | Working internet and app access | Permissions, file size and app status |
| iMessage | Wi-Fi or mobile data and active iMessage | Recipient, Apple settings and connection |
| RCS | Data and supported messaging service | RCS connection and default app |
| MMS | Carrier messaging service on the number-owning line | Home SIM, carrier support and roaming cost |
Do not turn on home-line roaming blindly to send one MMS. Check the home carrier’s charges first, because conventional messaging is outside the NoveSIM data service.
Test Whether Mobile Data Is the Problem
- Turn off Wi-Fi and load two ordinary websites over the eSIM.
- Send a plain text message through the same internet app.
- Send a small screenshot instead of the original photo.
- Try a second data-based messaging app.
- Check whether all contacts fail or only one conversation.
If websites also fail, follow the connected-without-internet guide. Verify that the travel eSIM is selected for Mobile Data and that Data Roaming is enabled on that line when required.
Check Permissions, Storage and File Size
Confirm that the messaging app can access Photos or Media and that the device has free storage. Try a compressed image or lower-quality sending option; carriers and messaging platforms may impose attachment limits.
Update the app through a trusted connection, then restart it. On Android, confirm the intended messaging app is the default when testing RCS or MMS. On iPhone, check whether the conversation is using iMessage or carrier messaging.
Check the eSIM Without Deleting It
Toggle Airplane Mode, restart the phone and retry a small attachment. If manual APN entry is required for NoveSIM, use data.esim with username and password blank.
Do not delete the installed eSIM. If all apps fail after the reversible checks, contact NoveSIM Support with the phone model, operating system, destination and safe screenshots. Never share the QR code or activation credentials.

FAQ
Why can I browse but not send photos?
The connection may be working while the app lacks photo permission, the attachment is too large or the message is trying to use MMS.
Does a NoveSIM eSIM support MMS?
No. It is data-only and does not provide conventional SMS or MMS. Internet messaging apps can send photos over data.
Why does a small photo send but a large one fail?
The service may impose an attachment limit or the connection may time out. Compress the image or select a lower-quality option.
Should I delete the eSIM?
No. Photo-sending problems rarely require profile deletion. Keep it installed unless NoveSIM Support specifically directs otherwise.
Final Recommendation
When an eSIM works but photos will not send, separate an internet-app problem from carrier MMS before changing network settings.
Test a small image in a second data-based app, then check permissions, storage, attachment size and the selected data line.
Preserve the installed eSIM and contact Support only after recording which apps, files and message types fail.
