Hello list,
I am marking this message as OT because it is not specific to
Openmoko, but I thought someone here may know because I think most
members of this list are relatively technical.
Anyway, why are SIM contacts (contacts stored on a SIM) so limited?
Cannot have multiple phone numbers per contact.
Cannot change the type (home, work, mobile, etc.) of the phone number.
Names are truncated to 18 chars.
Mainly, because SIM card entries have been standardized approx. 1992
so that you can use them in *any* phone. Back then, SIM flash memory
and computing power of a phone was *very* limited. Less than a C64 :)
It is similar to why plain old FAT memory card format is still in use
with all its limitations.
Why do I have to store contacts in the phone instead of on the SIM
to do anything useful?
Because you have much more memory and more flexible data formats. But
you can't simply remove the SIM and place it in a historical phone
like let's say a SIEMENS S4.
Thanks,
Brolin
