T-Mobile to Sunset MetroPCS's CDMA Network by 2015

The point is that Metro HAS gone to VoLTE, whatever their reason for doing so was, its a done deal. They have VoLTE handsets that they're pushing. So then to scrap the concept ( even if it was necessity based from the start) and the customers who use it currently will result in that much more alienation of their subscriber base. No upgrade path for your current device/service never inspires warm fuzzy feelings about your carrier.

Srich27 Essentially its just a matter of a few tweaks on existing equipment, no major changes required. However, MetroPCS has since day 1, as vikes pointed out for the sake of the spectrum crunch, allotted their LTE coverage almost exclusively for VoLTE coverage, and so on Metro's LTE network you barely pull 3G data speeds, nothing at all in comparison to the big 3 or even TMO's HSPA+. So doing away with VoLTE (even if its just for now) and focusing on TMO's desire to have LTE (which I dont even understand, their HSPA+ is fast as if not faster than current LTE speeds provided, and even if they switch, the 1700 band doesn't allow for roaming anywhere in the world except for with ATT, but I digress) would be paramount to giving up entirely on what WAS MetroPCS.
