Celcom Bulk SMS is a very reliable and affordable solution well aligned to the current customer experience needs. I have worked with them on several client's projects and the feedback is always positive; happy with the customer experience feedback. The kicker solution in my view is the SMS integration with billing and collection system which has enhanced collection. HIGHLY recommend the services to any customer. Thank you, Celcom, and keep up the good work!
