SouthernLinc Wireless indicated recently that the company has no plans to switch from its iDEN-based voice and data network to a different technology. In fact, the company will continue to invest in its iDEN infrastructure so that it can provide reliable push-to-talk services. SouthernLinc has offerred iDEN-based services for years. It has had a voice roaming agreement with Sprint, which also runs an iDEN network, in place since 2002. It expanded that agreement to include data as recently as 2011. SouthernLinc's customers will lose the ability to roam on Sprint's nationwide iDEN network when Sprint shuts it down by June 30, 2013. SouthernLink CEO Don Horsley said the company has a nationwide solution ready to replace the lost roaming capability, but he did not provide details on what that solution might be.
