Hi, This service provider, Switch2Voip.us is not at all recommended. They have all fake claims and false marketing.. I tired to get free US DID number but they did not gave me. But there website says they give free US DID number.. But in real they are not giving it. After that i posted review in their facebook about this where they replied to me that, they are giving free US DID number and contact him directly.. after this reply they block me from their facebook page so that i can not reply again. So i tired to register but still their is not free DID and at last again i talked with their customer care person who she replied me with same that they do not give free US DID .. i have taken screen shot of that chat also.. in short this service provider Switch2VOIP is not recommended and they give fake promises...
