I currently own a Handspring Treo.. which I *think* uses a 5V SIM. My SIM still says "Pacific Bell" on it (Cingular is my provider, and always has been).
I want to buy a Siemens S55, but as I understand it, it only accepts 3V SIMs.
Can anyone confirm for me that I do indeed have a 5V SIM? I assume I'll have to get a new SIM to work in the S55... but I was going to still use the Treo when I was traveling..
What are the chances of Cingular giving me a 3V SIM without taking away my 5V?
Thanks

No chance to have both for the same phone number. Think that 3V SIM also works on treo. But probably you can also consider on SE phones, 3V/5V SIM compatible.

SE phones? Is that an abbreviation for Siemens?
On Siemens web site, it lists the S55 as only being 3V compatible.

se is an acronym for sony ericsson
if you got your sim card recently, chances are it is a 3v. 3v sim cards usually have a smaller metal base for the chip (the shiny metallic part) and is usually rectangular or oval shaped.

Yeah, I figured that out after I posted the message
.
The thing that makes me think that it may be a 5v chip is because the SIM still says PacBell on it - and Cingular bought PacBell a few years ago.
