You’ve just moved into a lovely new house complete with everything you ever wanted—except the ability to call anyone. If you don’t seem to get a cell signal inside your home or office, here’s how to keep making calls and texts.
Enable Wi-Fi calling and texting
All four of the major U.S. service providers (Verizon, AT&T, T-Mobile, and Sprint), as well as a few other prepaid carriers, support a feature called Wi-Fi calling, which allows you to make and receive calls over your home’s wireless internet instead of a cellular connection. This works with text messages too, so you can keep texting your friends whether you have service or not. As long as your Wi-Fi is decent, you’ll be able to make calls throughout your dead zone of a house.
However, this trick has its limitations. Your carrier may not support Wi-Fi calling on certain older phones, or on models the company does not sell. If it does let you set up wireless calling, it may not allow certain phones to send picture or group messages over Wi-Fi. Make sure to check with your specific carrier to find out whether this feature will work for you.
Once you’ve checked whether your phone allows Wi-Fi calling, it’s time to enable this function. On the iPhone, head to Settings > Phone > Wi-Fi Calling and flip the Wi-Fi Calling on This iPhone switch to the On position. On the same page, you may also want to tap Update Emergency Address—this allows emergency responders to see your address as soon as you call 911 over Wi-Fi, which could be handy in a crisis.
Some carriers even support Wi-Fi calling from “iCloud-connected devices,” which means you can make a call on your iPad as long as Wi-Fi calling is enabled on both the tablet and your iPhone. To enable this, head to Settings > Phone > Calls on Other Devices. Flip on the Allow Calls on Other Devices switch, and then tap Add Wi-Fi Calling for Other Devices.
On an Android phone, go to Settings > Network & Internet > Wi-Fi > Wi-Fi Preferences > Advanced. (You can also just open the Settings app and search for “Wi-Fi Calling” to jump straight there.) Slide the Wi-Fi Calling toggle to On, and you’re good to go.
If you don’t have cell service at home or work, Wi-Fi calling is by far your best option. However, if you don’t see this option on your phone, then your carrier probably doesn’t support it on your device. In that case, I honestly recommend switching phones or carriers—it’s a lot easier than one of the other options below.
Try a messaging app
If Wi-Fi calling doesn’t work for you, and you’re unwilling to buy a new phone, you can still try another solution—though none of them are quite as seamless.
There’s a good chance most of your contacts are on Facebook anyway, so that’s a decent option—but it isn’t always as reliable as text messaging, since your friends may not receive notifications about Facebook messages or check the app very often.
If you’re willing to go through a bit more setup, Google Voice lets you make calls and send actual text messages using a regular phone number, and your recipient doesn’t have to download any special apps—they’ll just receive your calls and texts as normal. There’s only one catch: Google Voice doesn’t use your phone’s existing number; you have to pick a new number when you sign up for the service. That means you’ll have to either give this second number to your friends (so they know who’s calling), or port your current number to Google Voice, get a new number for your phone, and use the Google Voice app for all your calls and texts going forward. Like I said...it’s complicated.
Boost or create a wireless signal
Lastly, there are devices out there that can either boost or create a cellular signal inside your house. But they can also be complicated and expensive, and come with their own limitations.
Verizon, for example, offers a 4G LTE Network Extender for $250. This is a microcell device that uses your home internet connection to “create” a tiny cell tower within your house. AT&T used to offer a similar device, but has discontinued it since the release of Wi-Fi calling.
Not only are these devices expensive, but they allow anyone passing by your house to use your home internet for cell service. Meanwhile, if you have friends and family that use a different carrier than you, they won’t get a signal from it. If you want something that works with all major carriers, you can buy third-party microcell devices, but they’re even more expensive than the proprietary ones.
T-Mobile offers a different kind of network extender: Instead of using your home internet, it merely extends the network from a low-signal area (like a window) to a no-signal area (like the rest of your house). This requires that you have at least one bar of signal somewhere in your house, and it may require some finagling to get working properly. Still, it’s another option, and T-Mobile offers it for only a $25 deposit.
If you have a different carrier, there are other third-party devices that can do something similar. We recommend buying your device from a store with a good return policy so you can test it before committing, since everyone’s home is different.
Overall, Wi-Fi calling is the easiest and most reliable option—but if you absolutely can’t use it, these alternatives will work. You just have to be willing to spend time setting them up.
