All major US phone carriers have pledged to keep customers connected to their mobile lines even if they cant pay their bills during the coronavirus outbreak.FCC chairman Ajit Pai introduced a pledge on March 13 that Verizon, Sprint, AT-T, T-Mobile and other providers have affirmed, bringing the total to 185 providers according to a news release.The FCC's Keep Americans Connected Pledge asks signees to help customers in three ways for at least the next 60 days: not cut off service to residential or small business customers who cant pay their bills due to coronavirus disruptions, waive late fees incurred due to outbreak conditions, and open Wi-Fi hotspots to any American who needs them.AT-T, Verizon, and Sprint (via a tweet from CEO Michel Combes) have all publicly affirmed the Keep Americans Connected Pledge, while AT-T and Verizons enterprise arm have also extended this claim to small business broadband, according to Android Police.T-Mobile also affirmed the pledge, but is also extending its plans data allowances: limited data plans on T-Mobile or Metro will get boosted to unlimited, customers using tethering and mobile hotspots will get 20GB of additional data, and low-income Lifeline plans get 5GB of more data.Meanwhile, Mint Mobile customers will get free unlimited data through April 14, though theyll need to navigate through the Mint Mobile apps settings to buy more data in 3GB chunks - which will be refunded ASAP, according to Android Police.
