Sometimes my iPhone stops connection to 3G networks and making calls with the error "No Sim Card Installed". I tried reseating the Sim card but still the same problem appears. Can you please help me with this? Is it that my Sim card is malfunctioning?
Problem with Sim card installation
Your phone stopped connecting to 3G networks because the phone does not recognize your SIM card.
Â
If re-inserting your SIM card does not work, remove it again and make sure the SIM card slot is clean. Then try re-inserting your SIM.
Â
If there is still a problem, your SIM card might be the problem. Try inserting a different SIM card to know the status of your SIM card.
Â
Also try to get the latest version of your phone's OS. This will probably fix some bugs concerning your phone.
Â
If this is not still addressing your problem, your phone might be the one that is malfunctioning. You might need to go to the repair store.
