Hello, I see that my new Nexus 4 has a Data Roaming checkbox to enable or disable date roaming. But what about voice roaming (network roaming)? I could not find out any way to enable/disable this. On every other phone I have had, there was a selection for Automatic or Home Only to allow or prevent roaming. I have lost my network a couple of times and it did not automatically roll to a different network, so it seems network roaming is disabled. That's how I'd usually like to keep it. But there may be an occasion where I have no signal on my home network and need to make a call. So I'd like to figure out how to activate network roaming, just in case I ever need it. Any ideas? Thanks, b
