It's not free but their US and UK numbers are cheap, be warned though if you try to send an international text/SMS from your US or UK number they will use a free SMS gateway to send your text to the target number (Like if you send a text from your US number to Hungary or Australia they get a message from a third-party sender number not from the one you sent it too) apart from this small issue it works great and I would love to use it if the Australian number would be cheaper by a few dollars and it could handle receiving/sending SMS/texts too!This app have been good until i bought a number yesternight via googlepay i normally use which went successful and up till now the number is still pending in my order list and showing "exception" with an "...
