 Your carrier may charge for SMS messages used to activate iMessage ? 
 I was getting this message too whenever my iPhone restarts . Even though iMessage on my iPhone was working as expected as I was able to send and receive iMessages . 
 How can I turn this notification off ? Who can help me ? Thanks a lot !

 Just press cancel when it shows and it won ' t send the international sms to activate imessage with your phone number and it won ' t show until you restart . On the contrary , if you press ok the sms will be sent without you noticing anything except for the charge from your carrier . Mine charges 30 c of an € each time . . very upsetting . 
 Wonder why apple still got this crazy procedure in place : ( 
 It poped up everytime I cancel it . Apple sucks . Thank you !

 Well , yeah , maybe it doesn ' t yet suck but they seem to be desperately going in that direction , upsetting their customers is getting more and more common .

 Hold on here ! SMS is not the same as iMessages ! This gets into where the came from or whom you are trying to send a message to . 
 - If the other party used an iPhone / iPad or a Mac system then the message it ' s via iMessage which uses Apples servers and is free ! 
 - If the message came from a SMS source like a Google or Samsung phone or tablet then the cell carrier nicks you ! As this is using a side channel within the phone service Vs a TCP connection which iMessage uses . 
 Apple is warning you and allowing you to disable SMS messaging so you don ' t get charged . As you are getting this message over and over again you may have an app running that is trying to send a SMS message to activate something or your phone is now a bot ! As somehow you got infected with malware ! 
 I would scrub the phone down and slowly re - install my apps to see if you can find which one was infected . There are some iOS antivirus tools which you might want to try as well . 
 Lastly , you may want to review your cellular carriers offerings if you want ( need ) SMS services .

 @ danj Better read this . . you don ' t seem to be adding any relevant information to an already long debated matter 
 https : / / discussions . apple . com / thread / 805 . .. 
 Just to mention one of the many discussions about it . . 
 @ arbaman - Theres lost of confusion out there on what the difference is between the two services . And it can get very muddy as you can proxy your SMS message between your iPad and iPhone so the phone sends the SMS message . Which confuses things even more ! Let alone the fact you could be tunneling either via WiFi ! 
 There ' s a lot of mis - information out there . 
 The difference is how the connection is established using the cellphones carrier side - band channel or via TCP / IP which is how Apple does it . 
 The activation Apple is talking about here : If you get an error when trying to activate iMessage or FaceTime has to do with having a TCP socket connection between you and their server which is by - directional . In addition when using FaceTime your system and the called system need to establish a socket connection bi - directionally as well . 
 For simplicity sake we use the terms Client - Server and Peer to Peer in TCP / IP connections . Now what can get in the way is firewalls so while you can create a connection to Apple ' s server the person you are calling may not have an open socket established to Apples server for you to then create the Peer connection . 
 But none of this has anything to do with the cost of the message ! iMessage or SMS . Only SMS involves your carrier ' s servers which could cost you a fee . 
 As to the amount of TCP / IP data your plan offers thats a different subject as you can easily runout of your allotted plan using any TCP / IP connection Web surfing , games , iMessaging , VoIP and SameTime calls ( voice or video ) .
