MMS is not working properly. I tracked the problem to APNs with the wrong settings. My phone is a Blackview BV9900 and is using Android 9 and when I go to change the setting, all APNs are grayed out and there are no option to add or edit any. I called the technical support and told me until I can add or modified those settings they cannot help me. I should say the there are three APNs with toggle botton beside itbut none of then have the proper configuration. There is one APN which has the good setting but it cannot be selected ( no toggle button beside it) so i cannot tell the phone to use it.
Hey @Ineedtofixthis !
Welcome to the Community.
That's quite odd!
On the APN settings page of your device, do you see an option to ''Reset to default'', in the overflow menu?
If so, could you please try that and let us know how it goes?
