The companies I mentioned are substantially inferior in terms of engineering compared to twilio. Plus twilio is more transparent and trustworthy f.e. with porting out numbers. Voxbone is a Russian cheaper twilio clone. Plivo is an Indian cheaper twilio clone. Bandwith is a disaster. You just need to get a single look at their control panel which they won't show to you unless you're a paying customer.
