AT&T is showing its appreciation for those fighting the coronavirus by giving nurses and doctors three free months of service as part of its FirstNet program. The news was announced late Sunday night on John Krasinski's YouTube show Some Good News.

As part of the offer, those on the front lines of the pandemic will be able to receive the free service so long as they're on one of AT&T's FirstNet first responder plans. The deal is open to all verified, state-licensed nurses and physicians in the US and US territories, regardless if they are new or existing FirstNet users.

Doctors or nurses already on a traditional AT&T plan can switch to a FirstNet plan, which runs $40 a month for individuals for one line of unlimited talk, text and data. Those who also want unlimited mobile hotspot will pay $45 a month.

Medical professionals currently on a traditional AT&T plan or on a family plan with multiple lines will need to switch their individual line to FirstNet to take advantage of this promotion. They will also need to verify that they're licensed within 30 days of activation.

The process to switch, activate a new line and to verify a license can be done online. Additional signup details can be found on AT&T's FirstNet site.

In addition to the three months of free service, the carrier is also offering $200 off a FirstNet-ready phone when activating a new FirstNet plan. Most recent AT&T phones, including Apple's latest iPhone 11, 11 Pro and 11 Pro Max and Samsung's Galaxy S20 5G line, support FirstNet though 5G phones are still limited to AT&T's 4G LTE network.

FirstNet is AT&T's special service for first responders that takes advantage of a special band of the carrier's 4G LTE network to ensure that emergency personnel's service takes priority compared to those on regular AT&T plans during times of emergency.

AT&T has been deploying the network around the country, including adding portable sites around known hotbeds of the coronavirus, such as New York, to boost capacity and allow FirstNet devices to be faster than traditional AT&T phones.

The announcement is the latest from a wireless carrier to help out during the coronavirus pandemic. In March, Verizon announced that it would be giving extra high-speed data and hotspot data for its customers, while AT&T added more hotspot data for those on its unlimited plans. T-Mobile similarly announced last month that it would be making all plans on its network, even older tiered ones, unlimited for 60 days during the pandemic, in addition to giving out extra hotspot data.

Last November, as part of its efforts to help get its then-pending Sprint merger approved, T-Mobile announced plans to give first responders free service for 10 years under a program it calls Connecting Heroes. While the merger was finalized earlier this month, the carrier has yet to announce when that program will be available.
