Grasshopper is a basic VoIP solution for managing calls, texts, and voicemail. It is designed for small businesses that don’t need advanced capabilities to manage their minimal call volumes. All plans share the same set of features, like business SMS and call forwarding, so you don’t have to upgrade to premium tiers to access a specific feature. If the tiered pricing plans of RingCentral and Nextiva are too overwhelming for you, Grasshopper might be a great fit.
One of Grasshopper’s main strengths is its modern user interface and virtual phone number options. Subscribing to its plans lets you pick multiple phone numbers, whether local, toll-free, or vanity. Learn more about its virtual phone system in our Grasshopper review.
Grasshopper lags behind other VoIP providers when it comes to video conferencing and team messaging capabilities. In this case, consider Vonage, which offers over 50 voice and unified communications features on all plans.

Google Voice is a cloud-based phone system that works seamlessly with Google Workspace apps like Gmail and Calendar.
