Images sent over iMessages are low quality I capture images via iphone camera and attach to iMessages. When I send those over iMessages if it is using data image quality is very low. 

For an example.

5 MB taken image once it is sent over iMessages using data is 107KB

Please note that low image quality is always switched off. 

If I send over WiFi original image is received by other party.
Found the solutions after trying for several times. Finally. 

Following need to take place to send full quality image taken via iMessages.


Low quality image mode should be switched off
Enable 4G without 3G
Turn off low power mode
