Yeah! If you are in UG degree college, then usually there are no such restrictions regarding phone use. But if its a missionary college or a college with very strict discipline or if its an intermediate college,  then it may be possible. So the college in which you are admitted, you must check its disciplinary measures. Its dependent on the college you are studying and the disciplinary measures are there to restrict or allow.

I hope this answer helps. All the very best for your future endeavors!
