Hi and thank you for using Just Answer
I'm sorry to say, but this phone is done. I know you use to be able to get additional hand sets, but they have discontinue them now. They use to run somewhere between 41.00 to 80.00 depending on the class of store you walked into. As far as the base goes, they never sold them separately that I'm aware of. As for the good news, for the price you paid for this phone you can pick up a better quality one today. I do wish you the best.
