Hi all,
I have a V205 that I have flashed to G1. When I put the SIM from Cingular in the phone. Get the message that there is no service.
I currently have Cingular service and I would like to be able to switch phones. Also when I go to the service menu some of the menu is grayed out. Select service is set to automatic (grayed. If I switch bands to 1900 I can see the bars of service, but I still get no service? Please advise?
Thanks,
lnjj

How do you switch the bands on the phone? I recently got a Nokia 3108 w/Cingular service and am having the same problem w/the SIM card not working. I put the SIM card into a T-mobile-serviced phone (same 3108 model) and it worked fine.

Cingular suppresses the ability to manually switch networks.
As for the SIM card not working in a T-Mobile phone, there a couple things to consider.
1) The phone needs to be unlocked. The way GSM providers keep you on their network is by locking the phones, so that only SIM cards they issued will work in their phones. Usually, upon completing your contract, you can ask for the unlock code and your provider will give you an unlock code so that you can use other provider's SIM cards.
I'm not sure about the phone you mentioned, but there are also websites that you go to that will provide you the unlock codes for most phones for between $5-20.
2) If the phone is unlocked, and the phone still doesn't register on a network my guess is that you bought service on Cingular in a 850 Mhz area, and are trying to use a phone that only supports 1900 domestically. From what I can tell, Cingular is cracking down on these practices, as they pay roaming in those markets. If you're on a phone that supports 850 and 1900, and the phone is unlocked - I have no idea.

I found out from Cingular that my area only supports the 850 mhz setting, but the unlocked Nokia 3108 I purchased runs on 800, 1800 or 1900 mhz frequency, so basically I couldn't use the phone with Cingular no matter what I did (SIM cards worked fine in other phone models). What I did was took my number over to T-Mobile and I've been using the phone FINE since Friday. Works great. No complaints or problems PLUS T-Mobile has better minute and internet plans than Cingular (IMO). I'd been with Cingular since 1996 (they were still BellSouth) and have only owned 2 cells phoned previously. The Nokia 5185 and the 3360. I enjoyed Cingular's services while I had them, but it was time to try another carrier.

You're note is very interesting. The 3108 is a tri-band (900/1800/1900) device, which means it would work on ATT or T-Mobile's national networks. I neglected to notice that you were in New Orleans. I was down there for a conference last month; that is the first city that I've been to that Cingular doesn't have a 1900 mhz roaming agreement. It was sooo frustrating for my 900/1800/1900 blackberry (my V600 which is quad band 850/900/1800/1900 worked fine).
I called to complain to my B2B account rep, who wound up sending me a loaner 7280 blackberry (which is 850/1800/1900), which has been working great since I got it.
Keep me posted on what you think of T-Mo. I think they're fine for personal use, but would describe them generally as "not ready for prime time" for business applications. (wait till you see their bills - get a magnifying glass if you're interested in call detail).
I'm a firm believer in the old saying "you get what you pay for". In T-Mo's case, that's a sparsely populated network where dropped calls and overloaded circuits are the norm. Your phone has to be working properly for the phone to go to voicemail; if all circuits are busy, you'll get a fast busy instead of being dropped into voicemail automatically.
As of tomorrow, I will have successfully ported my family's last line away from T-Mo (too much aggravation). At one time, I had four lines with them. I've moved three of the four to Cingular, and one to ATT.
