I have a samsung j1 ace sm-j111m
If I start it without a sim installed it doesn't display the 'no sim' warning
If I start it with a sim installed it doesn't change the top icon for a sim being installed.
I've tried the online guides, ping tests fail and no luck I've tried using the sim card info app and it discovers the sim info and voicemail notifications come up
Thoughts? Possible fixes?
