Reliable but expensive
Works as advertised but the costs really add up. Good for enterprise but might be overkill for smaller projects.

Works as advertised but the costs really add up. Good for enterprise but might be overkill for smaller projects.
Does what it's supposed to do. SMS delivery is reliable and the API is straightforward. Customer support could be more responsive and the pricing feels a bit high compared to some alternatives. It's fine but not amazing.
The SMS functionality works perfectly, but we've had some issues with voice call quality being inconsistent. Sometimes calls are crystal clear, other times there's noticeable lag or audio artifacts. Their support team is helpful but resolution times vary. Still using it because the SMS service is reliable.
