*MT (Mobile Terminated) means SMS sent to the handset. Learn how MT works in SMS business messaging and why it matters for notifications and campaigns.*

---

**MT** (Mobile Terminated) means an **SMS** that is sent **to** the mobile device—the message “terminates” at the handset. In **SMS business messaging**, **MT** is the direction you use when your business sends alerts, notifications, or marketing to customers’ phones. Understanding **MT** helps you plan **SMS** campaigns, comply with carrier rules, and choose the right **business messaging** setup.

This guide explains what **MT** is, how it differs from **MO** (Mobile Originated), how **MT** fits into **SMS business messaging**, and what to consider for delivery and compliance. For **SMS** and **business messaging** options, see the [Spoki SMS](https://spoki.com/en/sms) page.]]></text>

    <section level="2" heading="MT vs MO: Two Directions in SMS">
      <text><![CDATA[**SMS** traffic is described by direction:

- **MT (Mobile Terminated):** The message is sent **to** the mobile device. Your system or platform sends; the handset receives. Typical uses: order confirmations, one-time passwords (OTP), appointment reminders, marketing (where allowed). In **business messaging**, **MT** is the main direction for outbound **SMS**.

- **MO (Mobile Originated):** The message is sent **from** the mobile device. The customer sends; your system receives. Typical uses: opt-in replies, support replies, keyword responses. **MO** is the inbound direction.

When you run **SMS** notifications or campaigns, you are mostly using **MT**. When customers reply or send a keyword, that is **MO**. Carriers and aggregators bill and regulate **MT** and **MO** separately, so knowing the difference matters for cost and compliance. For more on **SMS** and use cases, see [use cases](https://spoki.com/en/use-cases) and [solutions](https://spoki.com/en/solutions).]]></text>

    <section level="2" heading="How MT Works in SMS Business Messaging">
      <text><![CDATA[In **SMS business messaging**, **MT** flows from your application or platform to the mobile network and then to the handset:

- **Your system** generates the message (e.g. order confirmation, OTP) and sends it to an **SMS** gateway or API.

- The **gateway** routes the message to the correct mobile operator (carrier) for the destination number.

- The **carrier** delivers the message to the subscriber’s device (**MT** delivery).

Delivery rates, latency, and cost depend on the route (direct to operator vs aggregator), the destination country, and whether the message is transactional or promotional. In many regions, **MT** for marketing or promotional content must follow consent and content rules; transactional **MT** (e.g. OTP, order status) usually has clearer rules but still must respect local regulations. For a platform that handles **SMS** and **MT** routing, see [Spoki SMS](https://spoki.com/en/sms).]]></text>

    <section level="2" heading="When You Use MT in Business Messaging">
      <text><![CDATA[**MT** is used whenever your business sends **SMS** to a customer:

- **Transactional notifications:** Order confirmation, shipping update, password reset, OTP, appointment reminder. These are typically **MT** and often have higher delivery expectations and stricter rules on content.

- **Marketing or promotional SMS:** Campaigns, offers, reminders (where consent exists). Also **MT**. Many countries require explicit opt-in and opt-out for promotional **MT**; some require different sender IDs or routing.

- **Service messages:** Account alerts, balance notifications, or two-factor codes. Again **MT** from your system to the handset.

If you use **SMS** for business at all, you are using **MT**. The important part is to use the right route, respect opt-in and local rules, and track delivery so you can fix issues.

    <section level="2" heading="MT Delivery and Compliance">
      <text><![CDATA[**MT** delivery can fail for several reasons: invalid number, carrier filtering, content blocked, or route issues. To improve **MT** success:

- **Use valid, consent-based lists:** Only send **MT** to numbers that have opted in where required. Invalid or recycled numbers hurt delivery and can trigger carrier penalties.

- **Follow content and format rules:** Some carriers or countries block certain keywords, URLs, or sender IDs for **MT**. Keep content clear and compliant.

- **Choose a reliable route:** Work with an **SMS** provider or aggregator that has good **MT** routes to your target countries. Poor routes mean more failures and delays.

Compliance for **MT** usually means: consent (opt-in) for marketing, opt-out handling, and adherence to local **SMS** and privacy laws. For guidance, see [customer support](https://spoki.com/en/customer-support) and the [FAQ](https://spoki.com/en/faq).]]></text>

    <section level="2" heading="MT and Other Channels (WhatsApp, Voice)">
      <text><![CDATA[Many businesses use **SMS** and **MT** alongside other channels—for example **WhatsApp** for two-way conversation and **SMS** for OTP or alerts where **SMS** is required or preferred. **MT** remains the correct term for any **SMS** sent to the handset, regardless of whether the same business also uses **WhatsApp** or voice. Billing and reporting are usually split by channel: **MT** volume and cost for **SMS**, and separate metrics for **WhatsApp** or other channels. That way you can see how much of your **business messaging** is **SMS** **MT** and how delivery and cost behave over time. If you use a platform that offers both **SMS** and **WhatsApp**, you can keep **MT** for notifications and compliance-sensitive messages and use **WhatsApp** for support or marketing where the customer has opted in. **MT** delivery and **MO** replies (when the customer texts back) are often reported separately in dashboards, so you can monitor **SMS** performance and troubleshoot **MT** failures without mixing in other channels. Choosing a provider that supports both **SMS** **MT** and **WhatsApp** gives you flexibility to use the right channel for each use case while keeping one place for **business messaging**. For an overview of channels including **SMS** and **WhatsApp**, see [Spoki features](https://spoki.com/en/features) and [solutions](https://spoki.com/en/solutions).]]></text>
