ANCHORAGE - State phone regulators are investigating Sprint-brand prepaid calling cards over a reported decision to prevent consumers from recharging the cards if they're used in Alaska.
Regulators also want information on service problems such as dropped calls and blackout times.
The Regulatory Commission of Alaska says it has opened a formal investigation into the practices of STi Prepaid LLC, which provides service through cards with the Sprint label.
The RCA said the cards were sold at Sam's Club and possibly other retailers. They typically offered a 2.83-cents-per-minute rate.
STi took over the cards last fall and told federal regulators that customers would continue to receive services without any change in rates, terms or conditions of service.
State regulators recently ordered STi to reinstate the ability of Alaskans to recharge the cards.
