Around the World
Frequencies
My understanding is that the 850 and 900 freq. are only useful in the US. while the 1800 and 1900 are the bands used in foriegn countries.
So a tri band will work in any foriegn country.
This is relative to using local SIM cards.
Is this correct?
Thanks

I also have a v300 same Freq's.
I have used the 300 in Thailand, Colombia, Singapore and the U.S.
I got the 360 so I could direct phone numbers and pictures to the SD flash memory card.
My 360 doesn't seem to have the software to make such a choice. I tried with Moto Inc. and they couldn't help me. I can only use the SIM for numbers and the phone for numbers and pictures.
Also - when I put my Thailand SIM card in the 360 I got "no signal". I had my 300 with me just in case so I immediately changed back to it figuring my 360 had the wrong freq's.
So I am not sur the 360 works in Th. - I...

I can't help much with the flash memory part.
I agreed with you while in Th. but when I got back I saw the box label as exactly as the v300.
So I further followed up with Moto Inc. and they verified two times it to be 900.
(According to the chart on this site for all countries in the world, Th. DTAC uses only 1800.)
One was by the ICDM (spelling) number inside
Another was the fact that it was made in Singapore. They only make the eurasian model.
Maybe it was in a weak signal area - plus I didn't give it much time or move around. When on vacation no paitence for theat stuff - as well as not being positive it was the same(300)freq. at the time.
Thanks for your reply

Just hadd a electronic messaging failure.
You may get this twice.
I followed up on my assertion re: freq's.
Go to 'Links' in the blue column at the left
Find GSM association near bottom of page
On tool bar choose 'GSM Roamng'
On drop down choose 'GSM Coverage Maps'
Go to Thailand
Thailand
DTAC uses 1800
ACT GSM uses 1900
AIS GSM uses 900
My v360 has 1800 and I have a DTAC SIM card so the 850/900 issue should not affect me anyways.

Not quite. 850 and 1900 are the frequencies used in North America and parts of South America except for Cuba which uses 900.
900 and 1800 are used in Europe and in Asia mostly with a few countries in South America that use 900 or 1800 (such as Brazil.)
Bottom line, it could be you were duped with the phone regardless what is labelled on the box or depending on where in Thailand, you can get a variable signal. It's happened to me all the time when I was there.
