AT&T is cutting the price of its unlimited data plans

The fight over which cellphone carrier has the best unlimited data offering isn’t over. AT&T announced late Sunday that it is debuting two new unlimited plans this week — one, a no-frills option that tries to undercut its rivals on price; and the other, a more expensive plan with all the bells and whistles. Both plans will become available Thursday. The cheaper plan, Unlimited Choice, costs $60 per month for a single line (or $40 a line for a family of four), as long as you have autopay and paperless billing enabled. AT&T’s more expensive unlimited plan, Unlimited Plus, is essentially Unlimited Choice but allows for HD video streaming and includes 10 GB of tethering data. Once you use up the 10 GB of tethering, your speeds will be slowed. This high-end package costs $90 a month for a single line or $46 a month for four.

Samsung waiting to debut its new phone

A more cautious Samsung was on display Sunday at the Mobile World Congress, the annual technology show in Barcelona. As the company works to regain its reputation following last year’s unprecedented recall of the Galaxy Note 7 phone, it decided not to launch a new flagship smartphone at the show — breaking with tradition over the past three years. Samsung set the tone of its news conference with a video showcasing its safety testing procedures rather than touting the past year’s successes or offering a flashy product announcement. The company focused its presentation on new tablets, while announcing that its next phone will get its time in the spotlight at a March 29 launch event.

IRS criminal cases fall by 12 percent as agents leave

Sending tax cheats to prison has become increasingly difficult for the Internal Revenue Service amid an exodus of staffers from its Criminal Investigation Division and a 12 percent drop in new cases. Budget cuts and a battering by House Republicans led experienced criminal agents to retire, with the number falling 4.3 percent to 2,217 in 2016. Over the past five years, agent staffing levels have decreased 19.1 percent, according to an annual report released Monday by the IRS division. IRS Criminal Investigation agents enforce U.S. tax laws, but also work on money laundering, identity theft, cybertheft, narcotics and other nontax cases. Such “other financial cases” dropped 11 percent last year, while new tax cases fell 13 percent to 1,963. Combined, the decrease is about 12 percent.
