I have experienced two scenario while registering for Developer Program:

• If you have registered for Developer Program before using same mobile number then it's not allowing and showing same message as shown in your screen shot.
• If you are sure that you haven't registered for Developer Program before using this number then try to add your country code before the mobile number e.g.  911234567890 where 91 is country code (for me it worked -> but I tried this trick around 6 months ago)
