Do you have an antivirus? taskiller? task manager? how old is your SIM card?

[balajixp]

Yes I have 360 Mobile Security and my sim is 3 years old, but its a 3G sim only, as I can use it on my old c502 mobile.

1. uninstall taskillers, task managers, antivirus, etc, repair your phone with SUS and DO NOT install any app, just test your 3G.

or

2. get a new SIM card even if it work on another phone

Y u r saying me to Repair is there any problem with my mobile, is there any specifications like as H, which will be shown in my old mobile if there is any 3g signal. kindly help me with this I dont know wat to do

Check my suggestion above

[balajixp]

I have repaired my phone using SUS as you said but I still see the same signal strength as above?

Get a brand new SIM card

Obviously, there is a definite signal once your zr is connected with 3g....you would find an 'H' marking on the signal icon......
