Save up

You either have to earn it doing something, or do without until you can raise the money. It doesn't have to happen right now, work on it and when you can afford it get one. Not having a phone is not the end of the world. Also, do you need to pay for minutes and texting? That adds up fast.

If you're in the US, you can't buy a cell phone until you're 18. But if not. Then just save up. Ask neighbors if they need their lawns mowed or cars washed or something.

How about a GoFundMe Page. You're looking to do your homework and can't vecause you don't have the right tools to get it done. And in case you don't know what this is about, it's asking people to contribute to a cause that's needed and people actually give money to it. If that doesn't work, offer yourself out to older people/neighbors to help them out, maybe do their shopping or wash their cars for a fee. Which is probably is a more decent way of earning the cash you need than asking for charity. Give it a shot and good luck
