Gsm/umts
 

Hello guys,

i'm thinking of getting a new mobile phone (sidekick II) but it says i have to make sure my network is compatible with the following;

900/1800/1900 GSM and 2100 UMTS.

Does anyone know which networks use these? I am currently on 3.

Thank you.

umts I believe is 3g (used by any network giving 3g), 900GSM is used by O2 and vodaphone where 1800 is used by orange and T-mobile and 1900 not sure if used in this country is normally used in the states.

All in all it's a quad band phone and can be used on 99% of the networks around the world and probably 100% of the networks in the UK

GSM Networks in the UK all use either ~900mhz or ~1800Mhz

All the UK 3G networks are on the ~2100mhz band.

Generally speaking 900Mhz used to be o2/voda and 1800mhz used to be t-mobile/orange

But these days I think they use Both depending on what was available to them when they built the Mast.

Thats UK specs plus a bit of the US spec, you could use that handset on GSM in most of America (on the GSM 1900 frequency). US also uses 850GSM and UMTS on all sorts of frequencies. ATT use 1900, T-mobile use 1700, Canada and South America can use 850. It is a nightmare.
