Sending SMS on smartphones Android seems like a simple task - until you come across the nuances. Some users cannot find the standard Messages application, others do not know how to send SMS from a computer, and still others even encounter delivery errors. In this article we will analyze all current methods sending messages, including voice commands, automation and solutions for devices without a SIM card.

We will pay special attention to hidden functions built-in messengers (for example, delayed sending to Samsung Messages or backup to Google Messages), and we will also look at why sometimes SMS do not arrive and how to fix it. If you use Xiaomi, Huawei or Pixel , you will find instructions for specific firmware.

We’ll warn you right away: despite the popularity of instant messengers like WhatsApp or Telegram, SMS remains the only channel for confirming registration in banks, government services and some applications. Therefore, the ability to work with them is not a whim, but a necessity.

📊 How often do you use SMS?
Every day
Several times a week
For confirmation only
Almost never

1. Standard method: “Messages” application

The basic method of sending SMS is through the built-in application "Messages"** (the name may differ: Messages, SMS, Messaging). It is preinstalled on all devices Android, but the interface varies depending on the manufacturer.

On most smartphones (for example, Samsung Galaxy or Google Pixel) the algorithm is as follows:

  1. Open the application "Messages"** (icon with an envelope or speech cloud).
  2. Click on the button "Write"** (usually in the lower right corner, indicated by a pencil or a plus sign).
  3. B field "To"** enter the phone number (in international format: +79XXXXX or 89XXXXX).
  4. Enter the message text in the field below.
  5. Click on the button "Send"** (right arrow or airplane).

On Xiaomi (firmware MIUI) and Huawei (EMUI) the interface may differ:

  • 📱 In MIUI the button for creating a new SMS is hidden behind icon "+"** in the upper right corner.
  • 🔄 On Huawei sometimes you need to first select a SIM card (if there are two) before entering text.
  • 📌 In some versions EMUI field for text appears only after selecting a contact.

Important nuance: if you see a notification "SMS not sent", check:

⚠️ Attention: On devices with two SIM cards (Dual SIM), a card without an activated SMS service can be selected by default. Switch it manually in the message settings.

The correct SIM card has been selected (for Dual SIM)

The number is entered in the correct format (+7 or 8)

There is a network signal (not Airplane mode)

SMS service is not blocked by the operator

2. Sending SMS via voice assistant

If you need to send a message without touching the phone (for example, while driving or with your hands full), use voice commands. This method works on all devices with Google Assistant (pre-installed on most smartphones) or Bixby (on Samsung).

For Google Assistant:

  1. Activate the assistant with your voice ("Okay, Google" or hold the button "Home") or click on the microphone icon in the search bar.
  2. Say the command: "Send SMS"**, then give the contact or number and text. Example: 
    "Send SMS to Mom: Buy bread, I'll be back in an hour"
  3. Confirm sending by voice ("Yes" or "Send").

On Samsung s Bixby the algorithm is similar, but the command sounds like: 

"Hey, Bixby. Send a message to your wife: I'll pick up the kids at 18:00"

Method limitations:

  • 🎤 Voice commands only work when connected to the Internet (for speech recognition).
  • 📵 In noisy places (for example, on the subway), the assistant may not recognize the text correctly.
  • 🔒 On some firmware (for example, MIUI 12 and below), you must first allow access to SMS in the settings Google Assistant.
💡

If the voice assistant constantly makes mistakes in recognizing contact names, add alternative pronunciations to your phone book (for example, “Mom” and “Mommy”)

3. SMS from a computer: synchronization via Google Messages

Sending SMS from a PC or laptop is convenient if you work on a computer and do not want to be distracted by the phone. To do this, you will need an application Google Messages (previously Android Messages) and a web version of the service.

Setup instructions:

  1. Install Google Messages from Play Market (if it is not preinstalled).
  2. Open the application, click on the profile avatar → "Messaging devices"**.
  3. Select "QR code"** and scan it from the computer screen.
  4. Go to your PC at messages.google.com/web and confirm synchronization.

After linking, all your SMS will be duplicated on your computer. You will be able to:

  • 💬 Reply to messages from your PC keyboard.
  • 📎 Attach files (photos, documents) directly from Windows/macOS Explorer.
  • 🔍 Search through message history (including keywords).

Important clarifications:

⚠️ Attention: Synchronization only works when the phone is actively connected to the Internet (via a mobile network or Wi-Fi). If the phone is discharged or goes offline, sending SMS from the PC will not be possible.
Manufacturer Supports Google Messages? Alternative method
Google Pixel Yes (pre-installed) —
Samsung Yes, but you need to install it manually Samsung Flow (only for Samsung devices)
Xiaomi Yes, but may be blocked by MIUI Mi PC Suite (limited functionality)
Huawei No (due to lack of Google services) Huawei HiSuite + third-party applications

4. Automatic SMS: Tasker and other tools

If you need to send SMS on a schedule (like reminders to yourself or low balance notifications), use automation apps. The most powerful solution is Tasker, but there are simpler alternatives.

Method 1: Tasker (for advanced users)

  1. Install Tasker from Play Market and provide all requested permissions.
  2. Create a new task («+» → "Task").
  3. Add an action "Telephony" → "Send SMS".
  4. Specify the number, text and (optional) time of sending.
  5. Save the task and assign a trigger to it (for example, by time or when connected to a specific Wi-Fi network).

Method 2: Automatic sending via SMS Scheduler

  • 📅 Install application SMS Scheduler (free, there is a premium version).
  • 🕒 Click "New message"** and select the date/time of sending.
  • 📱 Enter the number and text, save the task.

Important: some operators (for example, Tele2) block automatic SMS if they are sent more than once per minute. In this case, messages may not arrive or may be sent with a delay.

How to bypass operator restrictions on automatic sending?

Some operators perceive frequent SMS from one number as spam. To avoid blocking:

1. Take a break between sendings (at least 2-3 minutes).

2. Use different text templates (do not send identical messages).

3. For mass mailings, it is better to use specialized services (for example, SMS gateways), rather than a personal number.

5. SMS without a SIM card: virtual numbers and online services

Is it possible to send an SMS if the phone does not have a SIM card? Yes, but this will require third-party services. This method is useful for:

  • 📱 Tablets with Android without a SIM slot.
  • 🌍 Sending messages to foreign numbers (if your operator blocks international SMS).
  • 🔐 Registration in services that require confirmation by phone SMS.

Method 1: Online services (free, but with restrictions)

Use sites like TextNow, TextFree or Receive-SMS. They provide virtual numbers in the USA/Canada/Europe from which you can send SMS via a web interface. Cons:

  • ⏳ Messages may be delayed (up to 10-15 minutes).
  • 🚫 Many services block such numbers (for example, VKontakte or WhatsApp).
  • 📵 Numbers often “burn out” after several uses.

Method 2: Paid SMS gateways (more reliable)

Services like SMS.RU, TurboSMS or Twilio allow you to send SMS via API or web interface. Suitable for business or regular mailings. Pros:

  • ✅ High delivery rate (95%) virtual.
  • 📊 Statistics on shipments and delivery.
  • 🌍 Supports numbers from different countries.

Important: When using virtual numbers to register with banks or government services, you risk having your account blocked. Many services check the “purity” of numbers and block virtual ones.

💡

To send SMS without a SIM card, it is better to use paid services (for example, SMS.RU) - they are more reliable than free ones and are less likely to be blocked by recipients.

6. Solving problems: why SMS is not sent

    FAQ: Frequently asked questions about sending SMS on Android

    Is it possible to send SMS to iPhone with Android?

    Yes, but if the recipient has iMessage (blue messages) enabled, your SMS will arrive as a regular text (green bubble). To ensure that the message is delivered:

    • Make sure that the recipient's number is not tied to iMessage (ask him about this).
    • If the SMS does not arrive, try sending it as an MMS (attach a blank photo).

    How to send an SMS to a short number (for example, 112 or 900)?

    Short numbers (banking services, emergency services) support only text SMS without media files. To send:

    1. Open the "Messages" application.
    2. In the "To" field, enter a short number (for example, 900 for Beeline).
    3. Enter text (usually a command, for example, BALANCE).
    4. Send a message.

    Important: Some short numbers work only through an operator (for example, 112 will not receive SMS if you are not roaming).

    Why is SMS broken into several parts?

    The standard SMS protocol limits the length of one message 160 characters (70 characters for Cyrillic). If the text is longer:

    • The operator automatically splits it into several SMS.
    • Each part may be charged separately (check the tariff with the operator).
    • To avoid splitting, shorten the text or send the message via messenger (for example, WhatsApp).

    Is it possible to cancel sending an SMS?

    No, after pressing "Send"** it is impossible to cancel the sending - the SMS immediately goes to the operator's server. The only exceptions:

    • If you have Google Messages with RCS enabled, the message can be recalled within a few seconds (but only if the recipient also uses RCS).
    • If the phone was not connected to the network, the SMS may get stuck in the queue - in this case, it can be deleted from the outbox.

    How to save SMS history when changing phone?

    Backup methods:

    • Google Messages: automatically synchronizes messages with your Google account (enable in the application settings).
    • Samsung Messages: use Samsung Cloud or Smart Switch.
    • Universal method: export SMS to a file through applications like SMS Backup & Restore (saves in XML or CSV).

    Important: SMS backups can take up a lot of space - regularly clear old messages.
