I sincerely need help. Am developing an SMS system to support administrative communication for an educational institution. One of the requirement of the system is that students will be able to inquire about their examination grade by sending a matricnumber, course-code and a password to a phonenumber/shortcode. The system responds by sending the exam grade to the user's phone number. I was relying on Twilio for this messaging but they notify me recently that they do not support 2-way messaging in Nigeria yet. Does any body know any reliable service provider that supports 2-way SMS in Nigeria? Pleases if you have knowledge or experience with any, it will be appreciated.Thanks
