Sprint Nextel has confirmed that it remains on schedule to decommission its legacy iDEN network on 30 June, starting at 12:01am Eastern Standard Time. Following the switch-off iDEN devices will no longer receive voice services – including 911 calls and push-to-talk (PTT) connectivity. The carrier says that it will shut down switch locations in rapid succession on 30 June, and will follow up by powering down equipment and eliminating backhaul at each cell site. The last full day of iDEN service for active users will be 29 June. ‘We strongly urge customers to migrate now to the Sprint Nationwide CDMA network to avoid losing service,’ said Bob Azzi, Sprint’s senior vice president (Network).
