When paying a bill for metropcs, can you pay in cash at the actual store?

You still have options without a checking account. One that comes to mind is buying a money order. You can get a money order at a bank, grocery store, or even Wal-mart and they usually don't cost any more than a dollar. You just tell them what amount you want the money order for and pay them that amount in cash. Then you mail the money order with your credit card payment stub to your credit card company.

You can pay in person. No problem. Get a checking account one of these days. A good step to take if you are 16 or 17, so you can fully undertand checking accounts by the time you are 18. --- Cash is 100% accepted. Just get a receipt.
