Yeah, it's definitely nothing to write home about. The old AT&T Wireless SIMs were better, and gave me warm fuzzies I actually have 2 unused, unpunched AT&T Wireless SIMs for nostalgia purposes
I wonder why Cingular/AT&T disables these features on SIM cards, as you guys say.
Get an unlocked/unbranded phone and you'll be A okay
Even unlocked phones adhere to the CSP profile and disable manual network select. If they don't, then it's because you're lucky that the phone software just happens to be non-compliant.
Several scenarios:
- I want to see what networks are operating in my area
- I am in an area covered by AT&T but I know that I will be driving through a dead zone. That dead zone is covered by a roaming partner's network that also covers the area I'm in currently. Inter-network handoffs are not supported. To avoid a certain dropped call, I force my phone to roam before making a call.
- I have enough AT&T signal to receive text messages, but not enough to make a call. If I do manage to get through, the call dies within seconds. The phone stubbornly wants to hold on to that last bar of AT&T even though a roaming partner's network is much stronger. In order to make a call, I force roaming.
whenever i choose the secondary network it only stays on it for a few minutes then goes back to the primary. does anyone know why? this happens to me with more than one phone.
-- as REAL as it gets as REAL as can be and just keeping it REAL -- 4EVER My Feedback

My old phone did this. The phone is constantly looking for networks higher on its preferred list than the one it's currently attached to. All the network select does is force it to register on that network, but the process of searching for other networks continues. I think you have to change network selection from automatic to manual to prevent this, although I never really cared to do that. If I wanted to use a secondary network to make a call, I'd just force the phone onto that network and quickly dial the call. Since most of the time the network can't hand off to the primary network in mid call, that effectively forced the phone to stay on the secondary for the duration of the call.
