I cannot send premium text messages. Whenever I try, I get 'error code 28'. I've gone into my settings and checked that premium messages are allowed (turned off and back on again), and have tried removing and reinserting my SIM card.
I also get a notification that I have voicemail messages appear every time I lose signal - but when I call my voicemail there are no messages. This has been happening ever since I changed over to iD last October.
Not sure if the two issues are linked in some way?
