This tool is similar to Callbell in that you can integrate various platforms such as WhatsApp, Facebook, Instagram, text messages and calls. One of the biggest differences is that Getgrasp is much more expensive than Callbell, with the basic plan being twice as much as Callbell's regular plan.
Customer support is also poor and the platform is not usually the first choice of companies, while Callbell offers a good price, good support and excellent quality. If you want a solution with good support, very easy to use and adaptable to all types of sites, Callbell may be what you're looking for.
