Best Radio ROM for roaming?

[evojulz]

My question is, when you are overseas using your local providers roaming options to still use your phone, should you use a radio that works best on the network in the country you are visiting or that works best on your home network?

I have tried 1.46.00.11 and 1.50.08.11 on my New Zealand Vodafone network and neither support incoming calls but other radio functionality works fine (also noted here (http://forum.xda-developers.com/showthread.php?t=326980)). So I stick with good old trusty 1.38.00.11.

When I go to Japan next week I want this still to work so I am hesitant to put the "leading (http://forum.xda-developers.com/showthread.php?p=1732829)" radio in the poll on as I may not be able to receive calls.

I will be using SoftBank in Japan, but I will be receiving calls redirected from Vodafone. I'll take a couple of radio ROMS on my card to flash if need be while I'm over there, but I was curious if anyone knew exactly what the biggest influence is, your location and network, or the calling users location and network?

Hey Julz, off to Japan huh? Fascinating place, make sure you check out Akihabara if you are in Tokyo...

I was in Korea a month or so ago and could get my P3600 to connect to their 3G network (using the 1.38 radio), couldn't make any calls but that turned out to be a Vodafone problem. Seems that VFNZ don't have a roaming agreement for their 3G network...

So I'm guessing you should be ok with the 1.38 radio.

Only other place I've roamed with the P3600 so far has been Fiji, worked perfectly there with the 1.38 radio.

Thanks Ant

Yes, this will be visit number 4 and yes I love Akihabara!! Will see if I can pick up a dirt cheap 8GB MicroSDHC down the alleyways.

NZVF confirms their 3G agreements with a couple of Japanese carriers, so it sounds like I should be ok.

Just thought it was an interesting question to chuck into the mix regarding favourite Radio ROM's to see if people change their radio when travelling ;)
