A newly published report claims Verizon and AT are the subject of a Department of Justice investigation.

According to the sources cited, officials are looking into whether the two carriers, as well as telecom standards organization GSMA, colluded to make it harder for customers to switch providers.

The Justice Department hasn’t confirmed the allegations at this time.

The information comes from half a dozen sources speaking the New York Times, which claims that the Justice Department demanded info from the trio over possible collusion over eSIM technology.

The sources further claim that the agency launched its investigation five months ago after receiving tips from a wireless carrier and at least one device maker.

That device maker was supposedly Apple, though only one source made that claim.
