Is it like the USA where you need a tri-band phone? A friends bf has gone to Brazil and she thinks he's not contacting her on purpose - but he only has a 3310 which I think is only dual band?

Hello

Looks to me like Brazil is covered by lots of networks (http://www.cellular-news.com/coverage/brazil.shtml).

Unlike me who is in Japan, and can't use my mobile phone. I feel stranded without it. Sad really!

Steve.

Hello!

It did sort of. GSM in the UK works on frequency 900/1800 and America 1900.

Looking at that website, it seems that several companies operate on the (UK) GSM frequency so a dual band phone should be okay.

Should be OK, unlike Mexico where no phone's work (not even tri-band)

She needs to have lifted the roaming bar on her phone and her network must have a roaming agreement with one of the networks over there.

I heard recently that some networks in Brazil operate on the GSM 1800MHz band.
I think in Mexico, they use AMPS or D-AMPS (like in US).
U'll have to rent a fone if u're travelling to Japan or Korea - Japan uses PDC, CDMA2000, W-CDMA (3G), & PHS; in Korea they use CDMA.
