Modern smartphones have become the main communication tool, and the ability to quickly send text messages is a basic skill for every device owner. Despite the abundance of messengers, classic SMS and MMS remain in demand for communication with banks, delivery services and in situations where the interlocutor does not have the Internet. The operating system Android offers an intuitive interface for working with notifications, but beginners sometimes have difficulty finding the right buttons or understanding the differences between message types.
In this article we will take a detailed look at the process of creating and sending messages on any device with the operating system Android. We'll look at the standard Messages application, which comes pre-installed on most gadgets, and also touch on advanced features such as RCS chat and group messaging. Understanding these mechanisms will allow you to not only send text, but also manage media files, delivery statuses and privacy settings.
No matter whether you use a budget smartphone or a flagship model from Samsung or Google Pixel, the logic for working with text notifications remains the same. However, the visual design of the menu may differ slightly depending on the version of the manufacturer's shell. We will focus on universal principles that apply to most devices released in recent years.
Launch the application and select a contact
The first step to start communication is to launch the appropriate software. On most modern devices, the default app Google Messagesis used, which has a green icon with a white speech bubble inside. You can find it on the home screen or in the all applications menu by swiping up from the bottom. If you are using a custom skin, for example One UI from Samsung, the application may simply be called “Messages” and have a blue icon.
After opening the application, you will see a list of all previous conversations. To write to a new recipient, you need to click on the special create button. It is usually located in the lower right corner of the screen and looks like a pencil, plus sign, or speech bubble with a “+” symbol. Clicking on this element opens a field for entering a phone number or name of a contact from your address book.
The system will automatically begin suggesting matches as you enter the first letters of the name or numbers of the number. This significantly speeds up the process of finding the right person in a large phone book. If the contact is not in the list, you can enter the number manually, and the system will prompt you to save it after sending the first message.
⚠️ Attention: Make sure that you enter the number in international format if you are writing to a subscriber from another country. This usually requires adding a “+” sign and the country code before the main number, otherwise the message may not arrive.
Use the “Pin Conversation” feature to ensure that important conversations always remain at the top of the list. To do this, you need to long press on the chat and select the pin icon.
Typing text and formatting a message
After selecting the recipient, the screen will be divided into two main zones: a list of correspondence history at the top and a text entry field at the bottom. Tap on the field Type a messageto activate the on-screen keyboard. Here you can type text using the suggested layout, or use voice input by clicking on the microphone icon on the keyboard Gboard or other input system you use.
Modern keyboards offer powerful tools for editing text right as you type. You can use word suggestions to speed up your typing, and instantly insert emojis and stickers by tapping the corresponding icon next to the space bar. To highlight an important part of the text, some versions of applications allow you to use bold font or italic, although in standard SMS this feature is limited compared to instant messengers.
If the message is long, the system will automatically break it into several parts. If this limit is exceeded, the message will be sent as several connected parts, but the telecom operator may charge for each part separately.
- 📝 Use swipe input (without lifting your finger from the keyboard) to quickly type words.
- 😊 Add emoji to convey emotions, since there is no intonation in a text message.
- 🔤 Watch the case of letters to avoid misunderstandings in business correspondence.
The text of the message is displayed in real time, and you can edit it before sending. If you make a typo, simply click on the error and correct the characters. Unlike some instant messengers, in classic SMS you cannot edit a message after it has already been sent to the subscriber.
Sending multimedia and attachments
Often there is a need to send not only text, but also a photo, video or audio file. For this purpose, a special toolbar is provided in the message input field. It is usually called up by clicking on the paper clip icon, plus sign or camera icon located to the left of the text input field. In the menu that opens, you will see options for attaching files.
When you select the option to add an image, the system will prompt you to select a photo from the gallery or take a new photo directly from the message interface. After selecting a file, it will appear as a preview above the text entry field. You can add a text comment to the media file, which will be sent along with the picture. These messages are technically MMS (Multimedia Messaging Service).
In addition to photos and videos, many modern versions of the Messages app allow you to send other types of files if the RCS (Rich Communication Services) feature is enabled. This could be a PDF document, a contact business card, or even a voice recording. Traditional MMS have strict file size limits (usually up to 300-600 KB), while RCS allows you to transfer files up to 100 MB or more using an Internet connection.
| Message type | Technology | Size limit | Requires Internet |
|---|---|---|---|
| Text SMS | GSM | 160 characters | No |
| MMS (photo/video) | GPRS/3G/4G | ~300-600 KB | Yes (mobile data) |
| RCS Chat | 4G/5G/Wi-Fi | Up to 100 MB | Yes |
| Voice message | RCS / MMS | Depends on length | Yes (for RCS) |
⚠️ Attention: Sending MMS and using RCS chat consume mobile data traffic. Make sure you have the appropriate data plan or data package to avoid unexpected charges.
Customize shipping and delivery options
Correct operation of the messaging function depends on a number of system settings that can be checked in the application menu. Go to the “Messages” settings by clicking on the three dots in the upper right corner and selecting Settings. Here are the key switches that affect the behavior of the application when trying to send data.
One of the most important parameters is the “Chat functions” item or RCS. If this option is active and the connection status is displayed as “Connected”, your messages will be sent over the Internet with high quality and support for indication of the interlocutor’s typing. If the Internet is unstable, the system can automatically switch to sending via SMS/MMS, which guarantees delivery, but will deprive you of advanced functions.
You can also find the “Group messages” option in the settings. Enabling this feature allows you to create chats with multiple participants, where all replies will be visible to everyone, rather than coming as separate private messages from each participant. This is critical for coordination in work groups or planning family events.
☑️ Check before sending
In the settings section there is also often a “Delivery Notifications” item. Enabling this option will allow you to receive a system message from the operator or server indicating that your email was successfully delivered to the recipient's device. This does not mean that the person has read the text, but confirms the fact that it arrived on the phone.
Working with group chats
Creating a group dialogue on Android is not much different from writing a personal message, but has its own management features. Start composing a new message and in the recipient field, enter the names of several contacts or select them from the list of suggestions. As soon as you add the second and subsequent recipients, the interface will automatically switch to group mode.
The group name will appear at the top of the screen, which by default is formed from the names of the participants, but which you can change at your discretion. This is convenient for identifying a chat, for example, “Family”, “Project Alpha” or “Friends for football”. By clicking on the group name, you can add an avatar and see the full list of participants.
It is important to understand the difference in the behavior of groups depending on the sending technology. If all participants support RCS, the group will work as a full-fledged chat in the messenger with the ability to leave the conversation, hide notifications and administer. If at least one participant uses an old phone without support for modern standards, the group can work in broadcast mode MMSwhere the functionality will be limited.
What to do if the group has turned into spam?
If there are too many messages in the group chat, you can turn off notifications for this particular conversation. Tap the group name, select Notifications, and turn the switch to Off. You will continue to receive messages, but the phone will not vibrate or ring.
Removing yourself from a group is not possible in all cases. In classic MMS groups, it is technically impossible to “unsubscribe” from the mailing list, since it is simply a list of addresses in the message header. The only way to stop receiving such letters is to ask the organizer to delete your number or block the sender.
Solving problems with sending messages
Sometimes users are faced with a situation where a message is stuck in the “Sending..” status or is returned with an error. The most common reason is the lack of a stable connection to the operator’s network or Google servers. Check the icons at the top of the screen: if there are no 4G, LTE, or 5G icons, you may be in an area of poor coverage.
Another common problem is the app memory being full. The Messages cache can grow large over time, especially if you actively share media files. To clear, go to Phone settings → Applications → Messages → Storage and click the “Clear cache” button. This will not delete your conversations, but will free up temporary files that may interfere with your work.
If the problem persists, try resetting the application to factory settings. In the same application management menu, select “Memory” or “Storage” and click “Reset” or “Clear data”. Remember that clearing data may delete SMS history if you do not have cloud synchronization enabled. After that, restart the device and check the function again.
⚠️ Attention: Settings interfaces and menu item names may vary depending on the version of Android and the model of your smartphone. If you do not find the described item, use the search inside the phone settings.
In 90% of cases, the problem with sending is solved by simply switching the airplane mode: turn it on for 10 seconds and turn it off to restart the communication module.
Blocking unwanted senders
Spam protection and annoying mailings is an important part of comfortable smartphone use. Built-in tools Android allow you to easily block numbers from which you receive unwanted messages. Open a dialogue with the unwanted sender, click on the three dots in the upper right corner and select “Block and report spam.”
After blocking, messages from this number will no longer be sent to your main inbox. They will be moved to a special “Spam and Blocked” section, which is usually located in the settings menu or in the main list of dialogs under the “More” item. You can go there at any time to check the contents or unblock a contact by mistake.
In addition to manual blocking, Google Messages has a built-in smart filter that automatically identifies and hides suspicious mailings from unknown numbers. If the system flags a message as spam, you will see a warning that the content has been hidden. You can click on it to read it or ignore it.
Can I send a message if I don’t have a SIM card?
Classic SMS and MMS require an active SIM card and a cellular network signal. It is impossible to send them without a SIM card. However, if you have Wi-Fi configured and “Chat functions” (RCS) are enabled, you can send messages to other RCS users via the Internet, even if the SIM card is not active for voice, but is linked to a Google account.
Why is the message not sent even though there is Internet?
This may be due to a mode conflict. Try temporarily disabling “Chat features” in the application settings. Sometimes RCS servers are unstable, and forcing a switch to a regular SMS network solves the problem. Also check to see if your balance has run out if you do not have an unlimited tariff.
How to send a message to a switched off phone?
The message will be saved on the telecom operator's server and delivered to the subscriber automatically as soon as his phone is turned on and the network appears. You will receive a delivery notification only when the recipient's device connects to the network.
Is it possible to change the color of the message bubble?
In the standard Google Messages application, the color of the bubbles depends on the type of connection: blue for RCS (chat) and green/gray for regular SMS/MMS. You cannot change this color scheme to a standard one (for example, make everything blue) without third-party themes or launchers, since the color serves as an indicator of the type of connection.
What does the triangle icon with an exclamation mark mean?
This icon appears next to a message that could not be sent. By clicking on it, you will see the reason for the error (for example, “No service” or “Insufficient funds”) and a “Retry” button, which will try to send again.
