From the last thing I was offered. The bottom line is billing when the handset is off. They said - it makes no difference whether it is turned on or not. Here the technique has arrived. Although, what can I say, on the network you can already download programs for controlling smartphones, etc.
And glad cell phones can be brought to mind. Then I put one cuckold instead of the "deuce" (because it’s expensive) just to record conversations on a voice recorder, on the phone with saving in a closed folder. All that remains is for him to quickly replace the memory card with his wife or throw the file on his bluetooth.
