On Thursday evening, a lot of iPhone owners (including some here at The Verge) are seeing the “not delivered” flag when trying to send texts via iMessage. Apple’s system status page hasn’t noted any issues as of 6:30PM ET, but reports across social media show something is going on. People have reported the problem across multiple wireless carriers (Verizon, AT&T, and T-Mobile), countries, and even continents.

If you are having issues getting texts out, then attempting to resend them has worked in some cases, but for now, it’s unclear exactly what is behind the issue or when it will be resolved.

The Verge has reached out to Apple about the problem, and we will update this post once there’s more information available or the problems have gone away. However, if your international friends are all saying, “Just use WhatsApp!” there isn’t really anything we can do about that.
