Help me to buy a new phone for my studies.

I've been using this phone for almost five years through this phone i can connect and study. it's been a big help to me to have a phone because our school activities are most online but now my phone just broke and I don't have a money to buy a new one, i know that my parents didn't have the money either because my brother is in college and i know that they didn't have the money so if you are ready to help me i need to raise money, thank you god bless you. I only need 100$ in order to buy but the minimum is 1000$
