Why cannot the photos be sent through SMS on the Xiaomi 14T?

If the photos cannot be sent through SMS on the phone, please refer to the following details:
1. Sending photos via SMS actually uses MMS, which requires mobile data. If you're not connected to a mobile data network or have no data available, the photo can't be sent;
2. There is a file size limit for sending photos via SMS, and larger photos will be too big to send via MMS;
3. If the phone number you're sending the photo to is incorrect, or the recipient's phone doesn’t support MMS, the photos will fail to send.
Note:
You can go to [Messages] >> profile icon at the right top of the screen >> [Message settings] >> enable [Send photos faster] to make photos sending faster.
