The New York attorney general’s office is investigating how T-Mobile’s  $26 billion deal to buy Sprint could impact competition in the pay-as-you-go wireless market, according to people familiar with the matter. Representatives from the state attorney general’s office have contacted companies that sell prepaid phone services in recent weeks with questions about pricing and customers. Dozens of other state attorneys general are part of the probe. Prepaid subscribers don’t sign long-term contracts and instead pay up front each month.
