Payment Method : PayPalSmartPaymentButtons

I encountered the same phone error last week.  PayPal expects it to be strictly numeric without special characters like dash or plus (there's a Regex sample somewhere in their documentation that I fail to find at the moment), so I edited ServiceManager.cs in the plugin like this to parse it:

if (!string.IsNullOrEmpty(billingAddress.PhoneNumber))
{
     var cleanPhone = CommonHelper.EnsureNumericOnly(billingAddress.PhoneNumber);
     orderDetails.Payer.PhoneWithType = new PhoneWithType { PhoneNumber = new Phone { NationalNumber = cleanPhone } };
}

The "no order id passed" error I found was due to mixing up sandbox/prod credentials.

Hi. Thank you for your help. We already have the issue ticket about phone number, you may follow it by this link to see it
