That meant that you had to end a call to look up information on the internet. With the introduction of the iPhone 6 and 6 Plus and a new feature in the Verizon network, one of the major headaches for Verizon iPhone users was removed. IPhone owners can talk and use data at the same time. The Problem While Verizon has long boasted the largest coverage area of any cellphone company in the U.S., the fact that you couldn't make a phone call and use data at the same time on an iPhone with Verizon was a big drawback compared to AT&T's service. Other Verizon phones that supported LTE could do this, but not the iPhone. That meant there was no way to be on a call and Google something related to the conversation or no way to get walking directions from a Maps app while talking to the person you were going to meet. That was a major limitation — one that convinced some people not to consider Verizon for their iPhone service provider. However, beginning with the introduction of the iPhone 6 and 6 Plus and some timely upgrades to Verizon's network, all of that changed. The key difference was the introduction of HD Voice, a feature previously known as Verizon Advanced Calling. With it, you can use your iPhone with Verizon service to make calls and use data at the same time. Verizon HD Voice Requirements In order to use Verizon HD Voice, you need the following: A compatible iPhone. All iPhones starting with the iPhone 6 are compatible, including the iPhone 6, 6S, 7, 8, X, XS, and XR.A Verizon monthly plan that supports the feature (which is basically all standard plans). HD Voice is automatically added to most monthly plans. To use it, you just need to enable a setting on your iPhone. To do that, get a compatible iPhone model up and running on the Verizon network, and then follow these steps: Tap the Settings app on your iPhone's Home screen. Tap Cellular. Tap Cellular Data Options. Tap Enable LTE. Tap Voice & Data. That's it. Return to whatever you were doing on your iPhone with the knowledge that you can now make calls and connect to the internet simultaneously. Other Verizon HD Voice Features Simultaneous voice and data use isn't the only feature that HD Voice unlocks for you. In addition, Verizon HD Voice customers can make conference calls with up to six lines and activate Wi-Fi Calling.
