AT&T Inc. (NYSE:T) has struggled to interest potential buyers in Vrio Corp. (ARCA:VRIO), its declining Latin American satellite-TV division, after actively peddling it for at least four months, according to people familiar with the situation. The problem with Vrio adds to the big challenges AT&T faces in its effort to raise cash and pay down debt by selling noncore businesses in a difficult market.

The people asked not to be identified discussing private information. AT&T declined to comment.
