HTC Desire 820 Dual Sim signal problem
Hi, I have HTC Desire 820 Dual SIM. SIM 1 Slot is defective, i use SIM 2 Slot where i want to use 3G\4G network but when i change network from 2G to 3G\4G SIM card signals disappeared. "Limited Service" appears. I know that 3G frequency i.e. 2100 MHz and 4G LTE frequency i.e. Band 3 1800 MHz supported by this device.
Any one give me expert opinion to rectify this anomaly.
