Data and Messaging on MetroPCS not working

Hey guys, I know I have not been a member long, but I really need some help. I recently switched to MetroPCS as my service provider from AT&T. All is good and well except I can't use data or send mms messages. I have searched the forums, called their customer support, and looked everywhere I could for info. I have changed the APN settings several different ways, and some of them will work temporarily, other times it won't at all. I am using an unlocked Nexus 6 running CyanogenMod 13 nightlies. These are my settings currently:
APN: fast.metropcs.com
Proxy:
Port:
Username:
Password:
Server:
MMSC: h**p://mms.metropcs.mmsmvno. com/mms/wapenc ***edited so I could post here :)
MMS Proxy:
MMS Port:
MCC:310
MNC:260
Authentication type:
APN Type: default,mms,supl
APPN protocol:IPv4/IPv6
APN roaming protocol:IPv4


Any and all help would be greatly appreciated!

Stock Messaging vs new Hangout

Starting today, the new version of Hangout has notification reply, which was basically the main reason I was still using the stock SMS app.
Now that they both have it, has anyone got any experience to share between the 2 apps as for battery consumption and bugs?
I'll be trying Hangout myself and report if anyone is interested.
Thanks!
