How it works

From VoIP.ms Wiki

VoIP.ms is a voice over Internet protocol provider, our service requires an Internet Service Provider (ISP) and works through SIP/IAX2 protocols, if you wish to update your regular telephone service to a new improved system of voice over IP you will need to get an Internet connection, an ATA device and a regular analog handset. Other options are using an IP Phone Devices, a softphone or a PBX server.

VoIP.ms offer a BYOD(Bring Your Own Device) service, we do not provide hardware, you can get your devices at any electronic store or you could choose for downloading a free softphone to install and use on your PC or cell phone.

VoIP.ms is a prepaid service that allows you to control your expenses, you can add funds with a minimum amount of $25 USD via Credit Card, PayPal, Bank Wire ($500USD minimum) or Western Union ($100 USD minimum), our currency is in US dollars. Your payments will be added to your balance and your calls and other charges will be debited from that balance, every time you run low on balance you could repeat this process again.

With us the INCOMING and OUTGOING calls are charged and handled SEPARATELY, the incoming calls are charged depending on the plan of the DID 
and the outgoing calls will be charged always per minute depending on the termination of the calls

Also note that is not necessary to have a DID to start placing outgoing calls, a DID number is meant for receive calls only and by registering correctly your device 
you can start making calls.
