I will correct myself in the statement about T-Mobile phasing out Metro, at the time I had read that press release, MetroPCS had not yet done its Reverse Acquisition of T-Mobile and maintain a 50/50 Shareholding to maintain it's place in the mobile empire. At the time of the intitial merger back in 2013, MetroPCS was not a 50% shareholder, the reverse aquisition had not happened yet. So yes T-Mobile was in talks of absorbing all MetroPCS stores and taking down the MetroPCS signs and putting up T-Mobile in it's place.
Now the deal is worked T-Mobile will handle Contract phone services, while MetroPCS will continue to maintain the Prepaid no contract services. However now T-Mobile is a "Public" company, before it was a privately owned company. Now the shares can be sold to any company of their choosing. So the future is up in the air. Maybe AT&T will now try to aquire again like they tried in 2013..

However I will not retract my statement that
CDMA is on it's way out. Because it is. Its going to VoLTE and VOIP, hence why our F6 has the option for wifi calling capabilities... Also, in limited capacity some companies will be launching their
5G networks in 2015, at least that's their projected launch date, not an official as of yet. Samsung, Huawei etc. etc.. So
BYE BYE CDMA!
In an interview with GigaOM, T-Mobile CTO Neville Ray said that T-Mobile would continue supporting
Metro’s VoLTE handsets and mobile VoIP service, but whether it would expand that service to its own network and handsets was still an open question.
Ray stressed that T-Mobile eventually plans to migrate its voice traffic to its all-IP 4G networks, but the big issue is timing.
In its initial manifestation, VoLTE probably won’t have much of an impact on consumers. Carriers will transfer their voice services from one network to another and likely charge the same rates for the service. But as VoLTE evolves, carriers will be able to offer a range of
multimedia and IP communications features. They will also be able to implement technical
enhancements such as HD voice (subscription required) that they simply can’t support on circuit-switched voice networks today. For carriers, there is an even larger implication in VoLTE.
Once they turn off their old voice network, they can phase out their 2G and 3G systems are repurpose that spectrum for LTE. Meaning no more CDMA.
In addition, T-Mobile isn’t planning to integrate Metro’s LTE systems into its own. Instead, it plans to shut down Metro’s radio and core networks as soon as the last CDMA phone goes offline. Ray said T-Mobile will keep about 1000 cell sites, and 6000 antenna nodes, but otherwise it will replace all of Metro’s gear with its own base stations and core. That includes the service delivery architecture – in telco parlance is called IP Multimedia System or IMS – that hosts Metro’s VoLTE applications.
Although MetroPCS uses CDMA phone technology and T-Mobile is based on GSM, MetroPCS is already in the process of phasing out CDMA, and its spectrum holdings are broadly complementary: both companies live and breathe in the 1,700 MHz and 1,900 MHz spectrum bands.
