disable message "Your carrier may charge for SMS messages used to activate iMessage"

This might be also the reason in my case. I switched to the virtual carrier (a carrier using another's carrier infrastructure and which has not been yet officially approved by Apple - this is also the reason why I cannot send MMS as was told by my virtual operator). I never had this message popped up before when I was with my previous carrier.

Apple has apparently rigorous procedures to approve new mobile operators.

I simply switched iMessages off in the phone's Settings. I personally don't need it. With Telegram, Viber, WhatsUp, unlimited SMS, Skype. Allo, Duo, you name it, Apple is missing out their opportunity.

What opportunity is Apple missing? iMessage is a free service. Apple makes no money from it. It actually costs Apple money to provide the service.

All your suggestions never worked. Still this annoying notification " your carrier may charge for sms messages used to activate imessage" still appears on my screen every couple of minutes and its irritating. I hope apple could help fix this now. I lost my prepaid load from this crap.

I too have this very annoying issue. I had activated Facetime earlier, but now I do not want use it. I tried the steps mentioned in this thread, but still the popup is keep coming. Very much disturbed with this issue. I am using iphone 6 with IOS 10.3.3. Please help.

to be honest, i seriously think the ios is full of flaws.

despite not activated and off mode, the phone can silently send activation sms out.

as you have guess, numerous roaming sms is charged, and the tech support claim its a silent sms by the phone to reach the server, and no way to stop it?

guess what the senior tech support escalated to software engineer despite multiple DFU restore, stuck in a limbo.

if you have a problem, apple cant solve it, just prolong you and asking you do kiddy stuff which is seriously puzzling.

for those who have similar problem, i observed a weird syptoms, the phone can send out sms despite sms centre is hard coded to remove the country code.

example +44 1234567 is the sms number, hardcode it to 1234567, sms still works normally.

but on a normal iphone which do not have this issue, hardcode to 1234567 will result in sms sending failure.

DFU after DFU restore as per proclaim it cant solve all the bug, it is not the case.

the hardcode bug is present, which mean imessage silent activation bug is present too.

so being a apple user, we have to pay tons of roaming sms for their software malfunction.

i do seriously think how common is this issue?

mine does not even show prompt, just keep sending roaming sms without my knowledge.

because my local carrier in my local country dont charge, so i didnt even know this happen until i am oversea.

apple failed badly in support, any support that prove worthy is around?

reading through the post, yet to see any.

a common folk can do better than apple, its a shame of their software engineer.

So then after you have signed out do you need to leave iMessage and FaceTime turned on? Or do you turn them off?

I have done this and the iMessage messages seem to have stopped but am still getting FaceTime activation messages. Is there some other app or setting that could be triggering it? FaceTime messages only started since latest OS installation. Thanks.

... and don't play with this:

Deregister and Turn Off iMessage - Apple Support

if you do it (i.e. you unregister your number) then you have to start from the beginning.

So you did the following:

• Go to Settings/Messages
• Turned it on if it was off
• Tapped Send & Receive
• Tapped on your Apple ID
• Tapped Signout on the dialog that appeared

I don't know if you can turn them off but is there a reason you don't want to use iMessage? It is much more secure than SMS.

You cannot disable it. You should only get it when you change the SIM or turn on iMessage or FT. Don't know why you are getting it and it has nothing to to with iOS 9.1 or .2 And you cannot downgrade to iOS 8.

I am having the same issue too (iPhone 6, iOS 9.2).

I have both iMessage and FaceTime turned off but keep getting the message which says "iMessage - Your carrier may charge for SMS messages used to activate iMessage." which is very annoying. I am an experienced iPhone user and have checked all the settings but the message just won't go away.

The message would pop up every day or every other day and I have the same feeling as Tingeltangelmike of being spammed by my own iPhone. I believe the message started appearing since I upgraded to iOS 9 but both iOS 9.1 and iOS 9.2 didn't resolve the issue.

And NO, I do not want to use Facetime / iMessage. I only want to be contacted via my mobile number, not my email address.

Any help would be greatly appreciated.

Did you try a hard reset?
