How much does Obopay cost?
It's just 10 cents each time you send money. So if you send money 10 times a month, you pay $1.00 that month. It costs nothing to receive money.
Is there a maximum amount I can send or spend?
You can send or spend only as much as you have in your Obopay account up to $200 per day.It's very easy to check your balance from your phone before you send money. If you've already downloaded Obopay to your mobile phone, just choose the 'Balance' option. Or you can go to wap.obopay.com to check your balance.
Also, you can withdraw up to $200 per day from ATMs using your PrePaid MasterCard ® and make bank transfers up to $200 per day.
And no worries if you try to send more than you have - we just won't send the payment.No ugly penalties or bounced check fees. Cool, eh?
