But i dont see any problem in giving an evidence ,instead if they send you an RFE ,your application will take some time again ,so I think it is still good to send but I don't mean Mr Bird is wrong.But concerning your bills ,you can either print out your phone bills ,I guess when you pay for your phone bills they usually keep record of that.Also if you have insurance ,you can get those bills from their website too.Infact bills include all you pay for a service but mostly will include those you use your SSN.Hope it helps
