If you go cell only you will end up with tele-marketers calling your cell. Drop lthe and line by going to something like ‘BasicTalk’ and give that number {or you transfered number} to those who need your phone number but you don’t want calling your cell.
...Forgot to add....keep your land line number...When I moved I could not transfer my number. Then discovered hundreds of people couldn’t reach me. Its those who only call once or twice a year but you want them to be able to reach you... the druggist, car dealer, the vet, aunt susie ...use an answering machine to screen out the tele-marketers
