I only advertise my landline numbers, but they are diverted to my mobile.
I used to take it off divert evenings/weekends but always went out the next day forgettign to put the divert back on

So I always have calls to my mobile 24/7, but I have to say I very rarely get any at unsociable times. I've just done a job for one customer who kept screwing around with their dates and would only ever p[hone me after 8pm or on a Sunday.
I finally managed to get rid of a weird guy last year who I mistakenly did a charitable favour for, which was a small job for virtually nothing. He kept calling me back to come and clean up his tea stains expecting a favour all the time, but always rang at 10 or 11 at night, or Sundays. I kid you not, I have about 7 numbers for him saved on my phone, he tried using different numbers to ring from to outwit me but he always got the voicemail!!
