PLS HAVE A CHECK ON YOUR PHONE TO KNOW IF ANYBODY IS MONITORING YOUR LINE. THE STEPS ARE VERY SIMPLE.
This is Very very informative!!
Please dial *#61# on your phone to know if your phone number(s)/line(s) is(are) being monitored!
When you dial the code (*#61#), it will show either line forwarded or not forwarded.
If it shows “call forwarding”; that confirms that your phone number/line is being monitored!
Therefore, do dial ##21# to remove the _“monitoring device” from that phone number/line! Then, no Secret security agent can ever monitor your line again. For a civilized Nigeria.
Please do this for ALL your phone numbers/lines!
