SMS (5)

Bangladesh gives its two SMS traffic categories names you will not find in any other market covered in this series. What most markets call an alphanumeric sender ID, Bangladesh calls masking SMS. What most markets call a numeric sender, Bangladesh calls non-masking SMS. The distinction is not just terminological. It determines whether your messages can reach NDNC-registered numbers, whether you can send outside business hours, which BTRC-licensed aggregator route is appropriate, and whether your brand name appears in the sender field at all. Getting the category wrong means either your messages reach the wrong numbers through the wrong route, or they fail to reach anyone reliably.

Acquisition gets all the attention...

But for FMCG brands, driving that second or third purchase can make the difference between a loss-leader and a flagship product.

And the fastest way to do it?

SMS.

It’s fast, personal, and already in every shopper’s pocket.

Most teams building SMS programs in Ghana discover the Sunday restriction after their first failed Sunday campaign. The setup seemed correct. The sender ID was registered. The contact list was clean. The messages were sent. And then the delivery reports came back empty, because promotional SMS cannot be sent on Sundays in Ghana, and it cannot be sent before 8 AM or after 7 PM on any day of the week.

Zambia is one of the more active SMS markets in Southern Africa for development sector, agricultural finance, and mobile money programs, and one where a specific carrier-level restriction catches international teams most often. MTN Zambia, the market leader, does not support dynamic alphanumeric sender IDs. A sender ID that has not been pre-registered and approved on MTN's network will generally be replaced by a generic numeric string, or may not deliver as intended. For a program targeting national reach across Zambia, that is not a technical footnote. MTN's market leadership means this requirement shapes how any program with national ambitions must be designed from the start.

A hotel group operating in Phuket, Koh Samui, and Chiang Mai has a messaging problem that most platforms do not design for. Its Thai guests expect to hear from it on LINE, Thailand's dominant super-app with approximately 56 million monthly active users and an open rate for business messages that exceeds 90%. Its international guests, arriving from Europe, Australia, China, the Middle East, and North America, expect WhatsApp, the app that was on their phone long before they landed in Thailand. SMS sits underneath both as the guaranteed-delivery layer for OTPs, booking confirmations, and critical operational alerts. And since October 2025, the National Broadcasting and Telecommunications Commission (NBTC) has required operators to flag international SMS with an alert symbol before delivery, which means unregistered international SMS increasingly arrives looking like a potential scam warning rather than a trusted hotel confirmation.

Every promotional SMS sent in the UAE must carry a specific prefix before the sender name or the message will not be delivered. The prefix is "AD-" and it has been mandatory since November 3, 2020, under TDRA regulation. A sender ID registered as "ACMELOGISTIC" cannot be used for promotional messages. It must be registered and submitted as "AD-ACMELOGISTIC." A sender ID without the "AD-" prefix will not be approved for promotional use, and promotional messages sent without it are likely to fail or be blocked at the carrier level. Most teams building UAE programs for the first time discover this requirement at sender ID registration, not during planning.

Since August 12, 2024, every business SMS sent in Vietnam must include the organization's brand name or application name in the message body itself, and that name must match the registered alphanumeric sender ID exactly. Not in the sender field alone, which is how every other market in this compliance series handles brand identification, but in the body of the message, as a mandatory line of content. A hotel sending a booking confirmation, an agricultural program sending a field update, a logistics company sending a delivery alert: all of them must open each message with the brand identifier that matches the registered sender name, every time.

Organizations running customer communication programs in the Philippines operate under a specific regulatory environment. Whether you're sending payment reminders, appointment notifications, OTPs, marketing campaigns, or service updates, several frameworks govern how customer mobile numbers can be collected, stored, and used.

Educational institutions rely on clear, reliable communication to keep students, families, and staff informed. This includes a wide range of organizations such as early childhood centers, kindergartens, primary schools, secondary schools, higher secondary schools, colleges, universities, coaching centers, vocational institutes, and community programs.

Managing patient appointments is one of the most important operational responsibilities in a clinic. It is also one of the most time consuming. Front desk teams answer inquiries, check doctor availability, send reminders, and manage cancellations or rescheduling requests. These activities keep clinic operations running smoothly, yet many practices still rely on manual communication to coordinate them.
