To send business SMS in Malaysia, agree your sender ID set-up with each operator and follow MCMC standards. Respect each network's content rules on links and phone numbers, keep promotional and transactional traffic separate, and send marketing only to opted-in customers. OmniChannels.ai, powered by BroadNet, sends SMS over direct routes to Celcom, Digi, Maxis and U Mobile. It also adds the WhatsApp Business API, RCS and voice, with fallback through one platform.

What to know before sending in Malaysia
A practical summary, not legal advice. MCMC standards and operator requirements change, so we confirm the current position for your traffic during onboarding.
| Item | Details |
|---|---|
| Operators and routes | Malaysia has four mobile networks (dialling code +60): Celcom (502-13), Digi (502-16), Maxis (502-12) and U Mobile (502-18). Celcom and Digi have been part of the CelcomDigi group since their merger completed on 30 November 2022. BroadNet reaches all four over direct routes. |
| Sender ID | Operators control how the sender is displayed on A2P SMS, and rules on sender IDs have changed over time. We confirm what each operator accepts and prepare the set-up with you. A typical lead time is 5 to 7 business days. |
| Links and phone numbers in content | Operators have tightened A2P filtering in recent years, for example with restrictions on links and phone numbers in message text. Before you launch, we check your templates against what each network currently accepts. |
| Promotional messages | We have not found a regulator-published time-of-day window for promotional SMS. Agree the sending hours with the operators, keep marketing away from late hours and send it only to opted-in customers. |
| Transactional and OTP traffic | OTPs, alerts and service updates can go out at any hour. Keep offers out of these messages so they are not filtered as promotional content. |
| Consent and opt-out | Send marketing only to customers who opted in and keep a record of that consent. Offer a simple way to opt out, and suppress opted-out numbers across every campaign and channel. |
| Multilingual content | Malay and English fit standard SMS encoding. Chinese needs Unicode, which fits 70 characters per SMS instead of 160, so keep Chinese messages short or check the segment count. |
| WhatsApp is widely used in Malaysia. Business-initiated messages need an approved template and customer opt-in. Meta charges per delivered message by category and recipient market, so confirm current Malaysia rates in Meta's rate card. | |
| Personal data | Contact lists fall under the Personal Data Protection Act 2010, which was amended in 2024. The amendments came into force in phases during 2025 and include data breach notification and data protection officer duties. |
How to launch business messaging in Malaysia
Sender ID set-up and content checks with the operators take the longest, so we start them in the first week.
- 1
Map your traffic
List your use cases and split them into transactional (OTP, alerts, receipts) and promotional (offers, launches, events).
- 2
Set up sender IDs
Share your company registration documents, an authorization letter and brand proof. We prepare the filing with you and submit it to each operator.
- 3
Connect WhatsApp
Onboard your number through Meta Embedded Signup and submit Malay, English or Chinese templates for approval.
- 4
Set fallback and integrate
Choose the channel order per use case and connect through the REST API, SMPP or campaign uploads from Excel or CSV.
- 5
Test on every network
Send to internal numbers on Celcom, Digi, Maxis and U Mobile and check delivery reports. Then launch within the agreed sending hours.
Is this the right setup for your Malaysian traffic?
A good fit when
- You send OTPs, payment alerts or delivery updates to Malaysian numbers and need operator delivery reports.
- You run campaigns in Malay, English or Chinese to opted-in customers.
- You want WhatsApp, SMS and voice OTP on one platform with fallback between them.
- You serve Malaysia alongside other Asian or GCC markets and want one provider for all of them.
Good to know before you start
- Sender ID set-up takes several business days, so it cannot be done on the day you plan to launch.
- Operators filter A2P content such as links and phone numbers. We cannot override a network's filtering decision.
- Marketing needs opt-in consent, and we do not send promotional traffic outside the agreed rules.
- MCMC standards and operator rules change, so we confirm the current requirements at onboarding rather than guaranteeing them in advance.
- Customers cannot reply to an alphanumeric sender ID. Use WhatsApp or a two-way number for conversations.
Malaysia business messaging questions
Which networks can I reach in Malaysia?
All four mobile networks: Celcom, Digi, Maxis and U Mobile. Celcom and Digi belong to the CelcomDigi group but still run as separate networks. BroadNet connects to each network directly, so delivery reports come from the operators.
Can I include links or phone numbers in SMS to Malaysia?
It depends on the operator and your traffic type. Malaysian operators have tightened filtering of links and phone numbers in A2P SMS in recent years. We review your templates and confirm what each network accepts at onboarding, so your messages are not blocked after launch.
When can I send promotional SMS in Malaysia?
We have not found a regulator-published time window for promotional SMS. We agree sending hours with the operators and schedule campaigns inside them. Transactional messages such as OTPs and delivery alerts can be sent at any time.
How much does SMS to Malaysia cost?
Our published rate card lists SMS to Malaysia from $0.032 per message. This is an indicative list price that excludes taxes, and your final quote confirms the cost. WhatsApp is billed at Meta's rate with zero markup; see our Malaysia WhatsApp pricing page. For RCS or voice pricing, contact sales.
Should I use WhatsApp or SMS in Malaysia?
Use both. WhatsApp is widely used in Malaysia and suits conversations, rich media and support. SMS reaches every phone without an app or data connection. Many businesses send WhatsApp first and fall back to SMS when a message cannot be delivered, which OmniChannels.ai configures per use case.
How long does it take to start sending in Malaysia?
It depends mostly on sender ID set-up and WhatsApp template approval. Sender ID set-up typically takes 5 to 7 business days and can take longer in some cases. We start it during discovery and confirm the expected timeline at onboarding.
