Despite its bare-bones feature set, Skype’s service plans include all the additional options we looked for in the best VoIP providers. You can keep your current phone number or choose a new one with an area code of your choosing, even if you don’t reside there. This VoIP service provides select international calling and unlimited minutes, depending on which of its plans you choose. You can also manage your account through the Skype web interface and make VoIP calls through the Skype app on your internet-connected tablet or smartphone.
