@rehtnap As you say there could be a few possibilities here. But are you confused with day Suzy rings Claudia as it was Day AFTER explicit disconnection from network. The phone disconnected the same day as their scheduled meeting and not the next day. "the next morning, when I tried calling her, I got a message saying her phone was out of service," so in the morning when she rang she got "out of service". Morning of Friday 20th March pretty specific she doesn't say went to answer service..maybe cl didn't have answer service switched on but it strikes me that the network couldn't connect to the phone rather than connect and it ring till no answer.. As you say, if she didn't have answerphone set up, you may well get an out of service message "she says next morning yet the phone wasn't switched off till 12.10 so do we deduce that the phone was at the time of her call/s in such a location it couldn't log onto the network????? If your out of range or phone is switched off-it would normally go to answerphone. Again-The next morning would be- Friday 20th March But we know that her phone made an Explicit Disconnection at 12:10 on Thursday 19th March 12:10 Phone powers down-An explicit power down meaning phone was actually “turned off” by someone rather than it running out of battery, being submerged or smashed.
