@AYA... In North America GSM networks use the 850 and 1900 Mhz spectrum. This message was posted from a T68i

@brix: Yes, but they run on TDMA (with the insight Scots gave). That should be why tri & quad band GSM sets can roam there, methinks. @scots: Can you name a couple of these cross-platform phones you referred to? Thanks. This message was posted from a P800

@AYA... Correct me if I'm wrong but isn't TDMA just a fancy name for GSM? This message was posted from a T68i

Triband phones have 900/1800/1900 mhz when in north america, these phones use the 1900 band width. Dual band phones do not have these and hence will not work. (At least that is what me thinks) @brix, you are very wrong, there are 3 main technology in second generation phones. gsm, cdma, and tdma. None of these are intercompatible.

Tdma = Time Division Multiplex Access. Gsm = Global Standard for Mobiles. They are entirely diff technologies. Will you pls try google? You can get loads of info there. (I confess, i am a bit confused. I know the working of gsm and cdma, but tdma i am lost.) (And i am not at all good with my communication skills.) This message was posted from a K500

I hope you were being sarcastic! If not then your comment is absolute rot, senior member indeed! I'm nothing of the sort and please don't label me as such. I'm not a fan of such titles.

@all

Getting back on-topic; GSM used narrow band TDMA, this article should give you a good understanding of the technology.

@scotsboyuk... In way I feel vindicated because in a previous thread I said that GSM and TDMA were related. This message was posted from a T68i
