I am rooted running stock ROM atm. Prior to rooting I went into Data mode (##3282#) and went into edit (MSL is all 0's). I copied all the APN settings. There total of 8x APNs in the Galaxy S3. EHRPD & LTE. There are varients for Admin, IMS, Internet & Tether. They are almost all the same as well. Will post them here.
For the Admin variants:
Name: EHRPD/LTE ADMIN (EHRPD or LTE depending on which type of connection, will say EHRPD ADMIN or LTE ADMIN)
APN: admin.cs4glte.com
Proxy: Not Set
Port: Not Set
Username: Not set
Password: Not Set
Server: Not Set
Authentication Type: Not Set
APN Type: fota
APN protocol: IPv4
APN Roaming Protocol: IPv4
Bearer: LTE/EHRPD (depending on if it is LTE or EHRPD)
For the IMS APN I will post only the differences from above.
IMS:
APN Name: EHRPD/LTE IMS
APN: ims.cs4glte.com
APN Type: ims
Internet:
APN Name: EHRPD/LTE INTERNET
APN: internet.cs4glte.com
Authentication Type: None
APN Type: Default,dun,mms
Tether:
APN NAME: EHRPD/LTE Tether
APN: tether.cs4glte.com
Authentication Type: Not Set
APN TYPE: tethering
Further, I inquired about signal and frequencies with CSpire. They have Band 12 of the 700MHz LTE Spectrum (Lower Blocks A& B). However, due to lack of devices, they broadcast the LTE on the 1900MHz spectrum in Northern Mississippi. This may be why custom ROMs are not working with 4G, ATT/Verizon utilize their 700MHz spectrum and so ROMs may be built to look there and not the 1900MHz spectrum.
Will not let me post the MMS settings as it contains a external url. lol
I did utilize CM10 Monthly build but noticed I do not get the 4G LTE. As mentioned above I believe its due to CSpire using 1900MHz for their LTE.
Also, prior to rooting I pulled the Latest PRL off of my phone utilize CDMA Workshop. Id put it here, but dunno how.
If you got LTE working let me know. I used the CM10 rom posted here and could not get 4G LTE at all.
