BBC mails to SMS

[hkl]

I am working on a way to use our SMS gateway to send notifications to our customers. 

Our SMS gate provider offers a Email-to-sms service which I plan to use to send SMS to customers.

 

By using the work around to send BBC mails: https://www.prestashop.com/forums/topic/149416-solved-bcc-copy-of-order-confirmation-mail/?_fromLogin=1 

I need to add the customers mobile phone number (including the country code) in the beginning af this mail.:

customers_mobilephonenumber[email protected] 

How to add the customers mobilnumber to this string?

$list->addBcc('[email protected]');

where xxxxxxxx = mobilnumber   ?

Any suggestions?
