"Your SIM sent a text message"

Hey... I tried the steps u suggested but I didn't receive any msgbox asking for carrier update and yet that dark screen saying your sim sent a text msg is appearing... please suggest me some other method to stop that

Same issue here on an iphone 6 (was restored from an iphone 5)....I get this now about 3 times after a restart but I don't see it any after that. I'm updated to 8.1.2 but no better.

Just had the same thing happen to me. Same device and service provider. I'm also curious about this.

I received the same message seconds after dropping my iPhone 6+. No visual damage done to the phone, as it fell flat on its back and has a case. iOS seems to be running fine except for this message showing up only once so far. I also have not lost connection with my carrier.

My only conclusion is that the phone detects that it has been dropped and generates this message. Where is the SIM sending the text message is my question? Apple?

yourskeptic,

Can you elaborate more on what fixed it? Mine has done the "No sim card" on three separate occasions now. I try rebooting the phone, but it doesn't always work. Seems like the only thing to solve it is time. Eventually it comes back. Starting to **** me off.

I got this on my 6 on AT&T. If you go to your Settings -> General -> About and just stay on that page for a moment, it'll ask for a carrier update. Complete that and you'll never have the message again. At least I didn't.

Upon quick research of this problem, it seems that this happens when the SIM is trying to contact the carrier's update server, however it does so in an endless loop. You should not be seeing that message and should contact AT&T to get it straightened out.

Same thing happened here. 6+ ATT, I havent noticed anything different yet.

Mine just did the same thing too - after upgrading to the latest OS.

iPhone 6+

Should I just ignore it & if it happens again, THEN I do a re-install? I'm not really understanding what to do after reading all these comments. I gather I should NOT call AT&T. Maybe it just does it the one time after people upgrade & that's ok & most of the time we don't see it? And I just happened to see it this time?

Same here. AT&T / iPhone 6 - updated to IOS 8.2 and soon after got the dark screen with "your SIM just sent text....".

... according to Apple, SIM is trying to contact carrier update server, happens with AT&T customers after updates, not really anything to worry about.

I'm not concerned so much as I am curious as to why this message is displaying. Have only seen in once (right after the update). Am currently running iOS 8.2. Would like to hear an official response as to what exactly is happening which is causing this message to display.

UPDATE:

So I chose to ignore the message. A couple of days later, while on the road, my phone lost service and came up "no sim card". I called Apple and after the regular reboots and messing with settings nothing would work. They had me pop my sim card slot open before, first time for me. After a few more settings were adjusted I popped it back in and it has been working fine since with no more messages (yet) about the sim card. I haven't synced since then so we'll see if that sim message comes back. If it does, back to Apple for a new sim card.

Solution, Maybe:

Called AT&T and described the "Your SIM Sent a Text Message" issue. Here are the steps that they had me do.

1. Call AT&T

2. From Settings choose Messages and turn on iMessages, Send as SMS

(Commentary: not sure why, but doing as told)

3. From Settings, General, Reset choose towards the bottom Reset Network Settings

4. Then make sure that you ask (NOT kidding) that they (AT&T) send "The Three Strongest Signals" they can!

(Commentary: Sounds like times of lore to me, but who am I to judge)

That's it! Seems to be working, will come back if it fails again. Good luck.

It sounds like something that is usually done without prompting the user. The phone probably notifies carrier that "hey, here is a phone with this model and firmware version, do you have an update?" which is sent as an SMS (short and sweet data transfer protocol).

Regardless, what's creepy and no one gives a hoot about, is the level of access a private company has to the bowel of your device. Thats how AT&T blocks or unblock feature on our phones (like tethering). They just send an "update" to the phone.

Its a shame that user has less access to the phone than a third party company. Touch ID security my ... .

Same here, only larger. 6+. AT&T. I've only seen it once so far, immediately after the update.
