I have a used Digital DA4000SBR-30U Cell Phone Amp/Repeater for sale. It was used on my house to improve the Sprint signal in my house, but I since switched to Verizon which works much better where I live. This unit will work great for all brands of cell phones and all services. It will actually be sold with a new warranty since we are dealers.
