Not sure how that would work then.
Many people who see your thread will be skeptical of your request even thought it's only 3 dollars.
Still, credit cards used for a total stranger raises many eyebrows in today's society as you can imagine.
I wish you good luck, as I don't know what to offer you
Well, if you can't get work, and you don't have the ID or cash to open a bank account and you can't figure out a way to buy a prepaid Visa card or PayPal account there...Go to a store where you can pay your cell phone bill. Whoever your carrier is, they have stores. Give a clerk whatever three dollars will translate into, and ask THEM to use THEIR credit card for you, in person.
If you don't know anyone who has a credit card or a PayPal account, that's a good place to start. But asking strangers on the internet? That's pretty useless. Or it could be a good scam to get credit card information, to make other purchases with it.
Of course, you could just save the three dollars, since you have no job, no income, and that should leave you enough time to let the ads run on the app.
