Hi All,

I have an interesting issue with my phone (S4 I9505) and after spending a few hours/evenings trying to resolve the issue I'm kinda on a dead end.. so I decided to get some info from here.

Had this S4 for a while (2nd hand, and was bricked, so could it cheap). Here in auckland and works fine, 4G and everytying. Went for a long weekend out of town with no 2degrees coverage and noticed that it would not roam on VF. My old phone (same sim) worked fine.  Note that I'm running a custom GPE rom. I've tried several settings but could not get it to work but gave up and enjoyed the view instead :) 

Once home I tried a VF SIM in the phone and that did not work either.

So I did some research and all is a bit vague but there is a setting "Settings->Mobile Networks->CDMA Subscription" which is on "NV". On my ROM it's stuck on that.. i.e. I can't change it to the other option "RUIM/SIM" and it appears it shoudl be on that?.  I tried flashing to cyanogenmod CM10.2 which is supposed to have that option working but did not work for me.

I can see Vodafone in the network list, but can't connect to it.

Is there anyone out there that has a S4 GPE and could let me know what version they are running, and what the Baseband/modem version is?  I'm running S4 JFLTE-GPE UltimaROM, Baseband version I9505XXUGNI1, Android 5.0.1.   The phone was originally a touchwiz version.

I'm about to flash another Baseband version which seems to fix similar issues of other's in other parts of the world but wanted to ask first.

Oh I also checked the APN settings, and all good.

Any help is appreciated.

Cheers
J
