I've paid for "TWO" numbers on this site. And every time I try to send a message. Or make a call. It goes to the "We just need a few more pies of information screen. With the "CONTINUE" bar across the bottom. And freezes up there. So for a service that will take your money in 3 seconds! You'd think it shouldn't take ?? minutes to make a call. Or send text!!!! If there was a "0" stars. I would have given it that!!!!!! So purchase at your own risk!!!!!!! TextNow is ""FREE" and runs a better app.

phone numbers have previous users, brought a number and was spammed calls and texts for services the previous user signed up for. From the second I recieved the number from onoff ive been getting 10 spam calls a day, annoying as hell. there is no spam protection or anything inplace to stop this from happening. do not use just buy a cheap phone and a second simcard

Most of the time it just works fine. If your signal is a bit marginal you may well find that calls fail to connect properly, which is annoying. It's easy to call back a customer but that doesn't look quite as professional as we would like. There is also a bit of a weird pause when answering calls which makes the start of the call awkward. It works for us (friendly local business) but is lacking the polish that some might be looking for.
