If you have experienced poor or no signal connection of your SUN cellular (Postpaid or Pre-paid) in some areas, kindly do the basic troubleshooting:
1. Try to on and off your unit
2. Remove Battery and SIM
3. Insert your SIM with other phone unit
This is to refresh our connection with SUN cellular. If, this not solve our problem with signal connection, try the following:
1. In our phone unit, go to settings
2. Mobile Networks
3. Operator selection
4. Choose manual connection
5. Choose SMART connection (this is due to merging of SMART and SUN cellular.)
If despite of above mentioned troubleshooting and did not solve the signal connection, check the physical appearance of your SIM card. A dirty SIM card can prevent your phone from reading the embedded data and connecting to a network. To clean the SIM card, rub the embedded chip (gold chip) with a soft eraser. After cleaning the SIM card, insert it to your phone unit and again check the signal connection.
