Galaxy S5 Active Call Forwarding issue "Network or SIM card error"
Just upgraded from the S3 to the S5 Active. Things seem to work fine, but when I go into the additional call settings (such as call forwarding), it says reading (as my S3 did), but then I get a "Network or SIM card error" and I cannot change any of these settings. Call forwarding is an essential need I have.
It was doing this on the Android 4.4, and last night I updated to Lollipop to see if that would help, but it did not.
Thank you in advance for your help.
