• Your number is a post-paid number with your existing mobile operator. Pre-paid numbers cannot be ported to Zero1.    
• Your number is not inactive/suspended with your existing mobile operator.                                                                                                    
• There is no outstanding balance with your existing mobile operator.                                                                                                        
• Your number is no longer under contract with your existing mobile operator.                                                                                                
• You cannot port-in Zero1 number to Zero1.
