When my business went under, so did my business number. Someone else got assigned it.

My mobile number went away after I cancled my service when I lost my job at the law firm. Someone else got my mobile number.

I am too poor to afford a business phone number or a mobile one. A friend of mine had a mobile phone he gave out as his business number and killed two birds with one stone. :)

If I do get a mobile number, it will be prepaid. I let a friend use my credit rating to get a mobile phone and he did not pay his last bill and it went on my credit report. Of course the mobile phones I have had always had the bills paid on time and in full.
