I agree.
There is also this weird corner case when the SIM has no SPN available.
AFAIK, a failed read isn't cached, so bootstrapping that particular SIM
will incur a penalty every single time for information that isn't even
available, as opposed to the GPRS atom incurring it just once during its
lifetime.
That reminds me, I think there are SIMs out there that use the CPHS ONS
instead of SPN, and these can be used interchangeably.
Jukka, don't you actually also need the ONS?
Cheers,
Aki
