I currently have ATT Wireless (who were bought out a year ago by Cingular). As part of my contract renewal, Cingular wants to switch me over to their system but they said it will necessitate a 64 meg sim card. They of course don't know anything about the SX-1 I have and don't have any specs on it. I think my current ATT Sim card is 30-something meg. Will the 64 meg sim card work in an SX-1?

Thanks,

I think SIM card sizes are still measured only in kilobytes (16KB, 32KB, 64KB, 128KB), thousands of bytes, not megabytes (MB), millions of bytes...

In any case, a newer SIM card should work just fine (the SX1 isn't that old a phone).

Yes, to update this thread, Siemens confirmed that the 64k (I should have said K, not meg) sim card would work. Sure enough, I have converted to Cingular service and have no problems so far.
