I do this consistently and really enjoy it. Eventually people get accustomed to the fact that I may be away from the phone all day, but I will get back to them. I think it’s relevant to mention here that a SIM is a consistent portal into everything you say or do around your phone, it would be difficult to cache spy content for upload when the network is available, but streaming…that’s easy. ESIM anyone? I’ll bet they’re all activated at the factory for some network you don’t even know is there.
