Which frequency does my phone run on here is the US???

[Guest nickcornaglia]

I was under the impression that the SPVs and Mitacs are Tri-Band Phones. 850/1800/1900.

My thinking was, when in Europe, the run on 850/1800 and when in the US they run 850/1900.

:?: 1) Someone said on another board that they only use 850 here in the US. Is that true?

:?: 2) I remember that on my SPV there was a Telephony setting in Settings called Band Selection where you switch between DualBand and PCS. I was assuming that Dualband was 850/1800 and PCS is 850/1900. Is that not true?

:?: 3) On the Mitac....there is no Telephony Band Selection Setting. Does it switch automatically or is my phone just running on 850 here in the US?

Is this the source of my reception problems or is it just poor coverage in my area under US-TMobile?

I don't know too much about US networks but this is as far as I know.

(there must be some US engineers out there that will confirm this)

1) Someone said on another board that they only use 850 here in the US. Is that true?

I think Cingular are using GSM850 to build their own network.

2) I remember that on my SPV there was a Telephony setting in Settings called Band Selection where you switch between DualBand and PCS. I was assuming that Dualband was 850/1800 and PCS is 850/1900. Is that not true?

Dualband in Europe is GSM900/DCS1800 (US is GSM850/PCS1900)

The SPV is triband 900/1800/1900.

Quad band phones are 850/900/1800/1900.

(I think GSM850/900, DCS1800 and PCS1900 were are all part of GSM specifications)

3) On the Mitac....there is no Telephony Band Selection Setting. Does it switch automatically or is my phone just running on 850 here in the US?

I'm not sure if the Telephony Band Selection affects the actual frequency scanning of the SPV - good question. It wouldn't include 850 though only 900/1800/1900.

Remember this one Mods ?

A topic that explains a lot about US networks and is also quite entertaining.

I think the best way to check GSM coverage is using network monitor on a Nokia phone. You need the software/cable to do this though.

I was confused a bit.

I forgot Cingular uses 850. I meant 900/1800/1900 for triband.

But I still have the question...how do you choose the band set on the Mitac?

[Guest martin]

Maybe you don't need to choose the band selection on the Mitac ?

When you turn the phone, it scans ALL frequencies in the avaliable bands looking for networks. So a Dual band phone will scan all frequencies in the GSM900/1800 bands.

We know that the Mitac works on GSM900/DCS1800 networks in other countries so if it works out of the box on PCS1900 networks then it must scan all 900/1800/1900 frequencies by default.

I though it was a bit strange that the SPV had seperate GSM/DCS and PCS selections in the first place. Is it a shortfall that the SPV is DESIGNED to scan for either GSM/DCS or PCS networks but not both ? Until recently I think the US had only used the 900/1800 frequencies for their TDMA networks so this may be the reason for it.

Have you used any other models of triband phone in the US that use the above bands ?

Before the Mitac....Nothing but the SPV.
