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

Right, though its not as though LTE isn't mentioned either, they mentioned the LTE data coverage they will gain without so much as a whisper toward VoLTE.

As customers upgrade in the short run, the idea is to immediately and exclusively sell them GSM/HSPA+ model phones offered via TMO. Again, not specified, but I imagine that they continue to sell the VoLTE MetroPCS models as well, though with no immediate coverage map growth, who's gonna buy those?? As it is I believe Metro is only supporting the technology in 6 markets? With nationwide coverage offered for a GSM phone, why would you go VoLTE and limit yourself? Either way, until 2015 the idea is to run parallel networks, with a COO salary allotted for each of them. Not to mention MetroPCS planning to expand their customer base by opening stores in TMO markets that they're not in already. I only hope (for their sake) that just means a corner of space in existing TMO's, and not new stand alones.

Clearly GSM is the obvious choice for the long run. Not only is the combined subscriber base larger on the GSM side, but that technology actually does allow for cheaper phones than CDMA, and far easier mobility for the end customer, not to mention roaming agreements worldwide.

While I personally am a fan, the CDMA roadmap is pretty much dying. And the LTE rollout will require money that they do not have. a Projected 2.1 billion in liquidity on the books by years end, plus the 4 billion dedicated from ATT does not a complete rollout equal. Sure it's a good start, but TMO has 15 billion in (internal) debt that DT is willing to take on and next to no credit options. Factor in that TMO is still losing subs quarterly, so is MetroPCS, and you have a well funded start to paving a dead end.
