"Your SIM sent a text message"

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.

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

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

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

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.

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

Same thing here - only time I've seen it, right after the 8.1.1 upgrade...

I've had mixed experiences calling AT&T previously about iPhone specific issues. What is the best way to describe the issue to them and what are we seeking them to do?

Just experienced this as well right after the 8.1.1 upgrade.

To close out my resolution....I tried a fresh install rather than a restore and I no longer get the SIM message. Never got a restore to work that removed this issue.

Had the same message right after it slid off the table onto the tile floor. erps

I Have an iPhone 6 using At&t sim card and just got the sa e problem on iOS 8.2

apple please help

Just saw this after 8.2 upgrade on iPhone 6 with AT&T. First time ever. Only saw it once.

Thanks for the info.

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?
