I have used Twilio for soi leads for years. It has worked well for years. Suddenly I have an issue where about 20% of my leads cannot view the links that I send them. I have checked the mobile operators, no specific operator seems to be blocking my urls. I have changed urls several times. I have even tested url redirect services to make sure that it was not an ip range for the domain that was being blocked. Twilio have a good set of tools that allow me to view the messages being sent and received, and it does appear that the urls are being sent and that Twilio are not blocking the urls. Anyone have experience with twilio and maybe have experience with this?
