A significant nationwide T-Cellular outage left hundreds of iPhone customers minimize off from the service’s community final night time, with many seeing the same old sign standing bars changed by a considerably cryptic “SOS” indicator.
Throughout the outage, which affected greater than 80,000 prospects at its peak, prospects had been unable to make common telephone calls or connect with any mobile knowledge providers. Wi-Fi connections nonetheless labored tremendous, in fact, so long as you had been lucky sufficient to be close to a pleasant Wi-Fi community.
Based on Downdetector the outage reached important ranges at round 10:30 p.m., with T-Cellular customers from California to New York reporting that the service was both principally or solely down for a lot of Monday night.
In a weird twist, the outage occurred on the identical day that T-Cellular’s President of Know-how, Neville Ray, announced his impending retirement. Within the subsequent tweet, solely seven hours later, Ray was apologizing for the disruption, explaining that it was the results of a third-party fiber interruption.
By early morning, Ray confirmed that the community was as soon as once more working at “close to regular ranges.” Whereas Downdetector continues to be exhibiting round 2,000–3,000 reviews of outages, that might be a results of prospects being extra on edge following final night time’s near-complete lack of connectivity.
Emergency Calling in iOS 16
What got here as a little bit of a thriller to many iPhone customers was the sudden look of an “SOS” indicator of their standing bar. Some assumed this represented Apple’s new Emergency SOS by way of Satellite tv for pc characteristic, however this left others perplexed as to why it appeared on older, non-satellite succesful fashions just like the iPhone 13. Some even puzzled if their iPhone was all of a sudden broadcasting an SOS message with out their data.
It’s not stunning that this would depart some of us confused, as this can be a new indicator that Apple added in iOS 16, and it’s not one thing most people would typically see on an iPhone when all the pieces is working the way in which it ought to.
The brand new “SOS indicator within the standing bar was seemingly impressed by Apple’s work on Emergency SOS by way of Satellite tv for pc for the iPhone 14 lineup, however it’s really only a manner of spotlighting one thing that the iPhone — and practically each different mobile phone on the planet — has been in a position to do for years: making emergency calls even once you don’t have a working service plan.
As we shared a couple of years in the past, within the U.S. and plenty of different nations, carriers are legally required to permit any suitable mobile gadget to make an emergency 911 name, no matter whether or not it’s related to mobile service. In reality, this could work even when your iPhone doesn’t have a SIM card inserted.
In fact, until you may have an iPhone 14 with satellite tv for pc connectivity, making a 911 name nonetheless requires a mobile connection of some form, and that is the place the iOS 16 “SOS” indicator is available in.
When your iPhone exhibits “SOS” within the standing bar, it signifies that your iPhone has a mobile sign out there for making emergency calls, however you’re not related to your individual service’s community.
This differs from the “No Service” indicator that each one iPhones used to indicate earlier than iOS 16. Nevertheless, even years in the past, “No Service” didn’t imply you couldn’t name 911 — however you had no manner of figuring out until you really tried it. With iOS 16, you’ll be able to inform the distinction: “No Service” means your iPhone can’t discover a mobile sign, whereas “SOS” means your iPhone can get a sign, simply not the sign you’re paying for.
The T-Cellular outage made this apparent since prospects had been all of a sudden with out their major community. But, they had been seemingly surrounded by ample protection from AT&T and Verizon, each of which might have handed on 911 calls ought to it have been obligatory for somebody to put one.
Since most mobile carriers have overlapping protection, it’s fairly uncommon for subscribers to any of the massive three carriers to seek out themselves in an space the place the “SOS” indicator would seem. Nevertheless, it’s one thing I encounter in Toronto practically each time I take advantage of the subway system since solely a single service gives underground mobile service — and it’s not the one I subscribe to.
Even when you’re utilizing an iPhone 14 with satellite tv for pc connectivity, emergency calls will nonetheless be routed by means of any out there service community inside vary. The Emergency SOS by way of Satellite tv for pc characteristic solely kicks in when there’s no mobile sign out there. On this case, the “SOS” indicator additionally seems barely totally different, with an icon of a satellite tv for pc proven beside the letters “SOS.”
Emergency SOS by way of Satellite tv for pc can be significantly slower and fewer environment friendly than a typical mobile 911 name since you’ll want to be within the line of sight of a satellite tv for pc, and there’s not practically sufficient bandwidth out there to make a voice name — you’ll be able to solely change textual content messages, and even these can take a minute or two to ship. In spite of everything, they’re travelling a number of hundred miles into area after which again to a floor station some place else on the planet.
