In order for your recipient to receive the funds, your recipient just needs to sign up with the mobile number or email address where the funds were sent to. If your recipient doesn't sign up within five (5) days from when the transaction was made, you will receive the funds back in your Coins.ph wallet.
Note: Transfers are generally final and irreversible. Please make sure the number or email address you input are correct for your recipient to be able to receive the funds successfully.
