Yes, in most colleges and hostels you can use mobile phones, but the rules vary depending on the institution.

1. Allowed in hostels:
   You can use your phone freely in your hostel room, but some colleges may set quiet hours or request students not to disturb others (especially at night).

2. Restrictions in classes or study hours:
   While phones are fine in the hostel, their use might be restricted during class hours, study hours, or library time. Repeated misuse might lead to warnings or confiscation.

3. Girls' hostels and strict colleges:
   In some colleges, especially in smaller cities or traditional institutions, girls' hostels may have stricter rules, like no late-night phone usage or monitored internet access.

4. Wi-Fi and signal:
   Even if phones are allowed, some hostels may not offer strong Wi-Fi or good signal, so it’s good to check beforehand.

Yes, in most hostels students are allowed to use mobile phones, but there may be some rules. You can usually use your phone in your room, but during study hours or at night, the hostel may ask you to keep it on silent or avoid using it. In some strict hostels, phone usage might be limited to certain hours to avoid distractions. It’s always best to follow the hostel rules and use your phone responsibly.
