Cognalys is a tool that aims to make mobile number verification less region-specific. SMS or traditional mobile phone messages are region-based. This is the major reason why mobile number verification prices go up. Cognalys chips in to overtake the existing conventional verification methods and replace verification messages with missed calls. The service is truly international, with presence in more than 200 countries. The service is offered for free, and there are also premium plans available. If you do more than 15 mobile phone verifications per day, you can go with the premium plans that start at $12 per month.
