This is a super important feature and we wanna make sure we do everything we can to get this working for you. Do you have internet access on the phone? If you have the option, you should see if you can change the APN settings to configuration on that page. You may need to give the phone a restart after that before you test out the picture messaging.
Could test out the setting in the link I posted? Please let us know if you still need help. Thank you!
Hey there. Please take a look at the link I posted and let us know if changing the settings helps with this. Thanks.
