If you’re aniPhoneowner currently living in a major American city, you may see the words “SOS only” on your status bar. You’re probably not the only one, because at the time of this writing, theUS is recovering from a major cellphone outageleaving tens of thousands without service.

This outage hit one of the US' largest wireless providers: AT&T (it’s unclear if any other service was offline or simply getting reports because T-Mobile, for instance, customers could not contact anyone on ATT). Cellular companies are working to restore service, but it may be a while until everything is back to 100 percent. Most smartphones will be left in the dark during this time. However, iPhones have aspecial SOS Only mode, retaining their ability to make calls to emergency services when the network is unceremoniously down.

Fortunately, you don’t have to wait until the network comes back online to make non-emergency calls as iPhones support Wi-Fi Calling. It’s a handy feature that, as the name suggests, lets you call friends or family through an internet connection instead of a cellular one.

Setting up Wi-Fi Calling

Setting up Wi-Fi Calling is easy to do.

First, open the iPhone’s Settings menu then tap the Phone option. Next, select Wi-Fi Calling, and in the following menu, toggle the switch next to “Wi-Fi Calling on This iPhone”.

Make sure you’re connected to a local Wi-Fi network and you’re good to go. You are now able to contact friends or family without having to wait until your carrier restores service.

Users also have the option to connect other devices to their smartphone so they can make calls on there too.

Eligible devices, likeMacBooksand iPads, will show up in the list below. Flip the switch on the hardware “you want to use with Wi-Fi Calling.” Once everything’s been set up, go to the device’s respective FaceTime app, enter the Settings menu, and turn on Calls from iPhone.

Ongoing dilemma

Even as we recover from the outage, no one appears to knowwhat caused the network to go offlinein the first place. One prevailing theory points the finger at solar flares that fired off on the night of February 21 while others suggest it was all because of human error. Lee McKnight, who is an associate professor in the iSchool at Syracuse University,told CNNa worker might’ve made a mistake somewhere on a carrier’s cloud network and no one caught it. Eventually, it snowballed into the current situation.

People are understandably frustrated. Hopefully, activating Wi-Fi calling alleviates some of the stress.
