Now virtually 9 days. Tried her mobile again and it rings with no answer. I would think that she would be back to work by now, but would have left by 7pm. Would a mobile that is switched on but not used at all last near to 8 days without the battery dying? There have been times a while ago when I hadn't heard from her for betweeen 1-2 weeks, but that was longer ago and before we were speaking on the phone & I had got the other phone with smart sim so she could text me cheaply and be easier for her to keep in touch when she couldn't get to a pc or be available on a phone.
