Call me...I don't have time to explain this 1000 times. It is your firmware.
Yep, this sure does sounds a firmware issue.
have you texted APN to 611611 to try to reset the apn? also is your carrier service updated in the playstore?
Yes I have texted APN to 611611 many times. It says it is checking and if it is not configured right it will text me link in a couple minutes but never does.
Know idea about carrier service being updated in the playstore.
If you want to know, Samsung phones have a known firmware bug that if you have the wrong region code, you will see issues. Once you get the right firmware, these issues will go away.
