Uninor / Telenor — I am not receiving any signal on my telenor sim card

Since last couple of weeks i am not able to use my telenor sim card due to no network. I am not receiving signal on that particular sim card ([protected]), no matter what i try. Not even using it in other devices, or traveling to other areas is able to provide me a single line of stable network. Several of my contacts and important messages are blocked due to this reason. For example, say, i am not even able to receive bank otps. Please help me out with this problem. I have no idea if the sim card is still working.
