I have received txts from a different phone to the one listed here but it is usually because the girl has run out of credit on her listed phone. The conversation continued on the other phone.

There was an occasion once where I "eventually" got a reply from a different number while I was on the way to an appointment where I was not sure if it was actually the girl I was going to see or not — she was cancelling the appointment, half an hour before I was due to meet her because "something came up"

Oddly enough I never heard from that girl again despite that fact that she regularly flirted with me on here before I made the appointment.
