Gramvoice is a virtual phone and communications platform for individuals and businesses that need flexible calling and messaging across borders. Users can obtain local, mobile, or toll-free numbers in more than 100 countries, including the United States, United Kingdom, Canada, Nigeria, Ghana, and South Africa. Numbers can be activated in minutes without a physical SIM card, contracts, or roaming fees.

Through a single dashboard or mobile app, customers can make and receive VoIP calls, send and receive SMS, and manage multiple numbers. Businesses can assign numbers to team members, route incoming calls, and support separate lines for departments, clients, campaigns, or sales and service operations. Individuals can also use a second number to keep their personal line private.

Gramvoice serves solo founders and distributed teams, with international calling available at per-minute rates and calls between Gramvoice numbers described as low-cost. The company provides guided onboarding, helpful documentation, and customer support around the clock.
