More than 70,000 AT&T cellular customers reported being unable to connect to service early Thursday morning. While early reports suggested multiple carriers, including Verizon and T-Mobile, seemed to be affected, that appears to be a knock-on effect of a major network going down.

Service monitoring site Downdetector was showing multiple post-paid and pre-paid carriers as having increased outage reports starting at around 4 am Eastern time. An Ars editor in Texas has seen "SOS" on their iPhone since 4:30 am Eastern time and has been unable to make Wi-Fi calls.

AT&T acknowledged the outage to CNBC , telling the network that it was "working urgently to restore service" to customers and that it recommended Wi-Fi calling until service could be restored. Verizon and T-Mobile told CNBC that they suspected their customers were reporting outages when they could not reach customers on AT&T or resellers that use AT&T networks.

T-Mobile has scrapped a plan to automatically switch users to newer, more expensive packages after hearing loads of criticism from customers.

The plan became public knowledge two weeks ago with the leak of internal documents that said customers would be switched to pricier tiers starting with the November bill cycle unless they contacted T-Mobile to opt out. Documents showed that T-Mobile customer service reps were trained to tell users who complained, "We are not raising the price of any of our plans; we are moving you to a newer plan with more benefits at a different cost."

But in an earnings call yesterday ( see transcript ), T-Mobile CEO Mike Sievert said it's no longer happening because feedback from angry subscribers showed it "isn't something that our customers are going to love."

T-Mobile is moving people to newer, more expensive plans starting with the November bill cycle unless customers call the company to opt out, according to multiple reports.

The forced migration surfaced on Reddit two days ago and was confirmed by The Mobile Report , which published portions of leaked documents indicating how the plan changes will be implemented. T-Mobile also confirmed the change to CNET, telling the news site that "there will be an increase of approximately $10 per line with the migration."

"We're always looking for ways to give our customers more from our services so we're moving a small number who were on older rate plans to newer plans that will deliver them enhanced features," T-Mobile told CNET.

A T-Mobile mistake during an overnight technology update resulted in some customers seeing the private information of other users today. T-Mobile users posting on social media said they saw other customers' billing details instead of their own during the incident that reportedly lasted for three hours or so this morning.

When contacted by Ars today, T-Mobile confirmed the problem and said it was caused by a faulty update. "There was no cyberattack or breach at T-Mobile," a company spokesperson said. "This was a temporary system glitch related to a planned overnight technology update involving limited account information for fewer than 100 customers, which was quickly resolved."

As The Verge wrote , T-Mobile customers "reported that they're able to see other users' account data—including their current credit balance, purchase history, credit card information, and home address—when signing into their own T-Mobile accounts."

T-Mobile yesterday announced a phone plan called "Go5G Next" that costs $100 a month for a single line, more expensive than the highest-tier wireless plans offered by AT&T and Verizon.

In a notable development for a carrier that spent years blasting its rivals' prices, T-Mobile issued a press release with a chart showing that its new plan costs more than the top-tier unlimited plans sold by AT&T and Verizon. AT&T's Unlimited Premium is $85 for a single line while Verizon's Unlimited Plus is $80 unless you add optional perks like the Disney Bundle.

T-Mobile's Go5G Next will be available on August 24 and come with unlimited phone data, 50GB of high-speed mobile hotspot data, and the ability to upgrade to a new phone once a year. It will also come with Apple TV+ and a Netflix subscription. T-Mobile points out that the similar AT&T and Verizon plans don't have streaming services included.

AT&T and other entities are trying to block the SpaceX/T-Mobile plan to provide Starlink satellite service directly to cell phones.

In a filing yesterday, AT&T urged the Federal Communications Commission to reject the SpaceX/T-Mobile proposal. "The FCC's rules do not permit SpaceX's proposed use of T-Mobile's terrestrial spectrum, and Applicants fail to even request—much less justify—rule waivers that would be necessary to authorize their proposed SCS [supplemental coverage from space] authorizations," AT&T said.

AT&T said it is interested in the proceeding because it has a license to use adjacent spectrum in the PCS C Block. AT&T says the SpaceX/T-Mobile plan, which was announced in August 2022 , could "jeopardize or inhibit the delivery of terrestrial wireless services," including mobile broadband.

T-Mobile on Monday said it experienced a hack that exposed account PINs and other customer data in the company's second network intrusion this year and the ninth since 2018.

The intrusion, which started on February 24 and lasted until March 30, affected 836 customers, according to a notification on the website of Maine Attorney General Aaron Frey.

“The information obtained for each customer varied but may have included full name, contact information, account number and associated phone numbers, T-Mobile account PIN, social security number, government ID, date of birth, balance due, internal codes that T-Mobile uses to service customer accounts (for example, rate plan and feature codes), and the number of lines,” the company wrote in a letter sent to affected customers. Account PINs, which customers use to swap out SIM cards and authorize other important changes to their accounts, were reset once T-Mobile discovered the breach on March 27.

The Federal Communications Commission says it wants to help satellite companies and mobile carriers partner up to close gaps in wireless networks. In a 4-0 vote, the FCC yesterday proposed "a new regulatory framework" designed to help satellite operators and wireless companies "leverage the growth in space-based services to connect smartphone users in remote, unserved, and underserved areas."

In August 2022, Starlink operator SpaceX and T-Mobile announced a plan to deliver space-to-ground service to mobile phones in areas not covered by T-Mobile's cellular network. SpaceX said this week that the companies plan to start testing the satellite-to-cell service sometime this year. Text messaging is expected to be the first supported service, with voice and Internet coverage to be added later.

The FCC said yesterday that "numerous such collaborations have launched recently, and the FCC seeks to establish clear and transparent processes to support supplemental coverage from space."
