Mobile App for checking RNC ID and how to check?

Team, Any one suggest how to check RNC ID Through app??

How do you check in tems?

If you have Qualcomm based Android device the best option is the Network Signal Guru app, but it requires root access.
Without root i can recommend apps such as G-MON, GNet Track.
