I have a Sprint S4 (SPH-L720) which i got from the states. I plan to use this in Canada...was able to root/unlock the phone via SIM Unlock Method posted (http://forum.xda-developers.com/show...light=sph-l720).
My issue is that i am unable to browse internet or use any apps needing internet on the GSM/UTMS network mode. I have a Rogers LTE chip that i am using and am able to use the phone (voice calling) with no issues. I can use internet on wifi but am unable to when trying internet via the phone chip...i do have a 6GB plan with Rogers and can browse internet when used on another phone.
I had to downgrade the Baseband to MDL/MDC to sim unlock the phone and have later installed MF9.
The software version and baseband now on the phone is: L720VPUAMF9. Earlier had an issue that the wifi was not working, option was disabled...(was getting a message - that an app is trying to connect...) this got fixed after i flashed the kernel version.
Can anyone advice how i can use data from the GSM network and not wifi.. has anyone faced the same issue.
