Sending SMS from an Android smartphone seems like a simple task - until you encounter unexpected restrictions: the message does not go away, the contact is not displayed, or you need to send SMS from your computer. Despite the spread of messengers like WhatsApp or Telegram, standard SMS remains in demand: to confirm registration, pay for services or communicate in areas without the Internet.
In this article we will look at all current methods of sending SMS on Android - from the basic Messages application to automation via Tasker or IFTTT. We will pay special attention to typical problems: why SMS does not reach, how to send a message to a short number, and what to do if the smartphone does not see the SIM card. And for advanced users, we will reveal the hidden functions of Android, which even manufacturers are silent about.
1. Standard method: "Messages" application
The basic SMS application is pre-installed on all Android devices, but its interface and capabilities depend on the OS version and the manufacturer's shell (MIUI, One UI, ColorOS etc.). The general algorithm is the same:
- Open the application โusually it is called โMessagesโ (Messages), "SMS" or has an envelope icon with a cloud.
- Click on the icon
โ๏ธ(new message) in the lower right corner. - In the "To" field, enter the phone number (in format
+79XXXXXXXXXor89XXXXXXXXXor select a contact from the list. - Write the text of the message (maximum 70 characters for Cyrillic in one SMS, then it is divided into parts).
- Press the send button (arrow
โor airplaneโ๏ธ).
On some smartphones (for example, Samsung Galaxy or Xiaomi Redmi) the Messages application can be replaced with a proprietary analogue. The functionality remains similar, but added bonuses:
- ๐น Message templates โ quick answers for common situations (on MIUI available in the menu
โฎ โ Templates). - ๐น Delayed sending โ schedule an SMS for a specific time (there is in One UI from Samsung).
- ๐น List of black numbers - blocking spam directly in the application.
โ ๏ธ Attention: If you use two SIM cards, before sending, check which of them is selected by default. On Android 12+ this is configured in Settings โ SIM cards โ SMS by default.
2. Google Messages: advanced functions
Application Google Messages (previously Android Messages) - an alternative to the standard SMS client with support RCS (Rich Communication Services). This is a protocol that makes SMS similar to messages in instant messengers: you can send files, see the โreadโ status, use reactions.
To use Google Messages:
- Download the application from Google Play (if it is not pre-installed).
- Open it and allow access to SMS, contacts i storage.
- Click
Start chatand select a contact or enter a number. - Write a message and send. If the recipient also has RCS enabled, you will see blue clouds (as in iMessage), if not - green (standard SMS).
Advantages Google Messages:
- ๐ Sending files up to 100 MB (photos, videos, documents) via RCS.
- ๐ End-to-end encryption (E2EE) for chats with other users Google Messages.
- ๐ Web version โ SMS control from a computer via a link
messages.google.com/web. - ๐ค Integration with Google Assistant โ quick replies and reminders.
โ ๏ธ Attention: RCS does not work in all countries and depends on the telecom operator. If the function is not activated, check support on your provider's website.

3. Sending SMS through instant messengers (WhatsApp, Viber, Telegram)
Many instant messengers can send SMS, but they do it in different ways:
- ๐ฑ WhatsApp โ sends SMS only to confirm the number during registration. Regular messages are sent via the Internet.
- ๐ฌ Viber โ supports SMS, but only if you provide access to messages (configured in
Settings โ SMS). - ๐ก Telegram โdoes not work with SMS directly, but you can use a bot
@SMSBot(paid service). - ๐ค Signal โ sends SMS as a backup option if the recipient does not have Signal.
The most convenient option for replacing standard SMS is Viber:
- Open Viber and go to
More โ Settings โ SMS. - Enable the option "Use Viber for SMS".
- Select a contact and write a message - it will be sent as an SMS if the recipient does not have Viber.
Disadvantages of this approach:
- ๐ซ Advertising โin the free version, Viber can display banners.
- ๐ Duplication โmessages are saved both in Viber and in the standard application.
- ๐ถ Dependence on the Internet โif there is no network, SMS is not will be sent.
4. Sending SMS from a computer
If you need to send an SMS without touching the phone, there are several ways:
| Method | Requirements | Pros | Cons |
|---|---|---|---|
| Google Messages Web | Android 5.0+, Chrome/Edge browser | Real-time synchronization, RCS | You need to scan the QR code from your phone |
| Samsung Flow | Samsung smartphone + Windows PC | Integration with the Samsung ecosystem | Works only on Samsung devices |
| Pushbullet | Installing the application on your phone and extension for browser | Support for notifications, files | Limit 100 SMS/month in the free version |
| MightyText | Android 4.0+, registration | SMS archiving, backups | Paid functions (from $5/month) |
The most universal option is Google Messages Web:
- Open on your phone Google Messages and click on the profile avatar โ
Message devices. - Select
QR code scanner. - On your computer, go to
messages.google.com/weband scan the QR code from the screen. - Now you can send SMS directly from your PC - they will be synchronized with phone.
โ ๏ธ Attention: When using third-party services (Pushbullet, MightyText), your SMS may be stored on their servers. If confidentiality is critical, it is better to use official solutions like Google Messages.
5. Automation of sending SMS (Tasker, IFTTT, MacroDroid)
If you need to send SMS on a schedule, under certain conditions (for example, low battery) or in response to events, automation will help. Let's look at three tools:
๐ง Tasker
Tasker โthe most powerful automation app on Android. To set up SMS sending:
- Download Tasker from Google Play (paid, there is a trial version).
- Create a new task (
+ โ New task). - Add action
Telephony โ Send SMS. - Specify the recipient number, message text and SIM card (if there are several).
- Save the task and assign it to an event (for example,
Time โ By schedule).
Example of use: sending an SMS to your wife when you leave work (by geolocation).
โ๏ธ IFTTT
IFTTT (If This Then That) allows you to link SMS with other services. For example, send a message when publishing a new post in Instagram:
- Register on
ifttt.com. - Create a new applet (
My Applets โ New Applet). - Select as a trigger
Instagram โ New post by you. - As an action -
Android SMS โ Send SMS. - Customize the message text and save.
๐ค MacroDroid
A simpler alternative Tasker. To send SMS when the battery is low:
- Install MacroDroid and open it.
- Click
Add macro. - Select as a trigger
Battery โ Charge level < 15%. - As an action -
SMS โ Send SMS. - Indicate the number and text (for example, โThe battery is almost empty, Iโll turn off soonโ).
โ ๏ธ Attention: Automatic SMS sending may consume credits on your tariff. Before setting up, check the cost of outgoing messages with your operator.
How to bypass the limit on the number of SMS in Tasker?
If your operator limits the number of SMS per day, you can use a workaround: send messages through email-to-SMS gateways. For example, for the number 89123456789 on MTS the address will be 89123456789@sms.mts.ru. In Tasker, instead of the "Send SMS" action, use "Send email" with this address.
6. Hidden Android functions for working with SMS
Android hides several useful features for working with SMS that are not obvious at first glance:
- ๐ก SMS via Wi-Fi/4G (without SIM) โ some operators (for example, Tinkoff Mobile or Yota) allow you to send SMS via the Internet, even if there is no SIM cards. To do this, you need to install their proprietary application.
- ๐ SMS redirection โyou can set up forwarding of incoming messages to another number. On most smartphones, this is done through a code: enter in the calling application
*21*NUMBER#and press call. - ๐ฑ SMS from another number โif you have two SIM cards, you can manually select which number to send the message from. In a standard application, this is done by long pressing the send button.
- ๐ SMS encryption - applications like Signal or Session can encrypt the text of messages, but the recipient must also use the same software.
Important: Android 10+ has a hidden setting that allows you to block SMS from unknown senders at the system level. To activate it, go to Settings โ Google โ Security โ SMS spam blocking Another little-known feature (for example, for USSD requests or service commands). Many applications block such messages, but you can bypass the restriction: Settings โ Google โ Security โ SMS spam blocking.
Another little-known feature - sending SMS to short numbers (for example, for USSD requests or service commands). Many applications block such messages, but you can bypass the restriction:
- Open the standard "Phone" application.
- Enter a short number (for example,
112or*100#). - Click call button, and then in the menu select
Send SMS(if the option is available).
If you need to send an SMS to a short number, but the phone is blocking it, try adding a country prefix to the number. For example, instead of 112 enter +7112.
7. Typical problems and their solutions
Even with a simple task like sending an SMS, difficulties can arise. Let's look at the most common ones:
โ SMS is not sent
Possible reasons and solutions:
- ๐ถ No network โcheck the signal level or switch to another SIM card.
- ๐ณ Not enough money โ for some operators, sending SMS is paid (for example, 1.5 rubles per message).
- ๐ต SMS center is not configured โthe center number should be registered automatically, but sometimes it gets lost To check. enter in the calling application
##4636##, then go toPhone information โ SMSC. - ๐ง Error applications โ clear the Messages app cache in
Settings โ Applications.
๐ The message leaves, but does not arrive
If an SMS is sent (disappears from the "Outbox" folder), but the recipient does not receive it:
- Check whether the recipient is blocking your messages.
- Check whether your operator supports SMS reception (sometimes there are failures with virtual operators).
- Try sending a message from another number.
๐ต The phone does not see the SIM card
If the smartphone does not detect the SIM, SMS cannot be sent it will work out. Actions:
- Restart the phone.
- Remove and insert the SIM card back (after turning off the device).
- Check whether the contact on the SIM card is bent.
- Update the operator settings: enter
##4636##โPhone information โ Update PRL profile.
๐ฑ You cannot send SMS to a short number
Many applications block sending to numbers shorter than 5 characters. Workarounds:
- Use a USSD code instead of SMS (for example, instead of SMS to
112just dial112and press call). - Add a country prefix (for example,
+7112instead112). - Install an alternative application for SMS (for example, Textra or Pulse SMS).
โ ๏ธ Attention: SMS center settings and operator tariffs may change. For accurate information, check the data in your provider's personal account.
If SMS is not sent, first check the balance and signal level. In 90% of cases, this is where the problem lies.
8. Alternative applications for SMS
The standard Messages application is not always convenient. Let's consider the top 5 alternatives with unique features:
| Application | Key functions | Cons | Link |
|---|---|---|---|
| Textra SMS | Themes, delayed sending, blocking spam | Advertising in the free version | Google Play |
| Pulse SMS | Synchronization with PC, backup, blacklist | Paid subscription for some functions | Google Play |
| QKSMS | Open source code, night mode, RCS support | Fewer features than competitors | Google Play |
| Chomp SMS | Templates, spam blocking, notification personalization | Outdated design | Google Play |
| Signal | End-to-end encryption, self-destructing messages | SMS only works as a backup option | Google Play |
If confidentialityis important to you, the best choice is Signal or Session. For maximum customization, Textra or Pulse SMS.
When choosing an application, pay attention to:
- ๐ Security โwhether the application supports encryption.
- ๐ฑ Synchronization โwhether you can manage SMS with PC.
- ๐๏ธ Backup โare messages saved in the cloud.
- ๐ก๏ธ Blocking spam โis there a built-in filter for unwanted messages.
FAQ: Frequently asked questions about sending SMS on Android
Is it possible to send SMS without a SIM card?
Yes, but with reservations. Some operators (for example Tinkoff Mobile or Yota) allow you to send SMS over the Internet without a physical SIM card if you have their virtual number. You can also use services like Google Voice (not available in all countries) or email-to-SMS gateways (for example, send a letter to NUMBER@gate.mts.ru for MTS subscribers).
How to send SMS to iPhone from Android?
SMS from Android to iPhone is sent the same way as to any other phone - through the standard Messages application or alternative clients. However, if the recipient has iMessageenabled, your SMS may arrive as a green bubble (standard message) rather than a blue one (iMessage). To ensure that you send an SMS and not an iMessage, ask the recipient to temporarily disable iMessage in the iPhone settings.
How many characters can be sent in one SMS?
It depends on the encoding:
- GSM-7 (Latin, numbers, basic characters) - 160 characters.
- UCS-2 (Cyrillic, hieroglyphs, emoji) - 70 characters.
If the text is longer, it is divided into several SMS. For example, a message in Russian of 140 characters will be sent as 2 SMS.
Is it possible to cancel sending an SMS?
No, the standard SMS protocol does not support cancellation of sending. However, some operators provide a short window (usually 3โ5 seconds) during which the message can be recalled. To do this you need:
- Immediately after sending, open the message menu (long press).
- Select the "Cancel sending" option (if available).
Also, some applications (for example, Pulse SMS) allow you to delay sending for a few seconds in order to change your mind.
How to save SMS to the cloud?
There are several ways:
- Google Messages - automatically synchronizes SMS with your Google account (configured in
Settings โ Backup). - SMS Backup & Restore โan application that saves messages to Google Drive or to an SD card.
- Pulse SMS โoffers cloud storage as part of a subscription.
- Manual export โsome applications (for example, Textra) allow you to export SMS to a file
.xmlor.csv.
Important: when backing up SMS to the cloud, keep in mind that messages may become available to third parties (for example, if your Google account is hacked).
