Text messaging, also called SMS (Short Message Service), is one of the most basic features on any iPhone. It allows you to send written messages to other phone users through your cellular network or internet connection. Unlike phone calls, texts let you communicate without speaking, which makes them useful in situations where you cannot talk, such as during meetings, in loud environments, or when you want a written record of a conversation.

Every iPhone comes with a built-in Messages app that handles text messaging. This app appears on your home screen as a green icon with a white speech bubble. When you open it, you see a list of your conversations organized by the people you have texted most recently. Each conversation shows the last message exchanged and the date it was sent.
Text messages travel through your cellular provider's network. When you send a text, it goes from your phone to your provider's servers, then to the recipient's phone. This process typically takes just a few seconds. The cost of text messaging varies depending on your phone plan. Some plans include unlimited texting, while others charge per message or include a set number of texts each month.
iPhones also support iMessage, which is Apple's messaging system. iMessage sends messages through the internet rather than through your cellular network. Messages sent via iMessage appear in blue bubbles in the Messages app, while regular SMS texts appear in green bubbles. iMessage works between iPhones, iPads, and Mac computers, but not to Android phones or other devices.
Practical takeaway: Before using text messaging extensively, check your phone plan to understand whether you have unlimited texting or if there are limits and costs associated with sending and receiving messages.
The Messages app on iPhone includes several features that go beyond basic text messaging. One of the most useful is the ability to send photos and videos directly through text messages. Simply open a conversation, tap the camera icon at the bottom of the screen, and choose whether to take a new photo or select one from your library. You can send multiple photos at once, though this may use more of your data.

Group messaging is another common feature. You can create a conversation with multiple people by selecting several contacts before starting a new message. Everyone in the group receives messages sent to the conversation and can see replies from other group members. Group messages can be useful for coordinating plans with friends or family, but they can also become overwhelming if many people are responding frequently.
Read receipts are a feature that shows the sender when you have read their message. This appears as "Delivered" when the message reaches your phone and "Read" with a timestamp once you open the conversation. You can turn read receipts on or off in your settings. Some people find them useful for knowing whether someone has seen their message, while others prefer the privacy of not showing when they read texts.
The Messages app also lets you search through past conversations. You can swipe down from the top of the Messages list to reveal a search bar, then type keywords or a person's name to find specific conversations or messages. This is helpful if you need to locate important information from a text conversation that happened weeks or months ago.
You can also customize notifications for text messages. Your phone can alert you with a sound, vibration, banner, or badge number on the Messages app icon. You can set different notification styles for different people or groups, so you might get a loud alert for important contacts while other messages arrive silently.
Practical takeaway: Explore your Messages app settings to understand which features are turned on and which you might want to adjust based on your privacy preferences and communication style.
Every message you receive and send uses storage space on your iPhone. If you do not manage your messages, they can eventually use a significant portion of your phone's memory, which may slow down your device or prevent you from storing photos and other files. Text messages that include photos or videos use more storage than simple text messages.

The Messages app makes it relatively straightforward to delete conversations and individual messages. To delete an entire conversation, swipe left on a conversation in your messages list and tap the trash icon. To delete individual messages within a conversation, enter edit mode by tapping "Edit" in the upper left corner of a conversation, then select specific messages and tap delete.
Some people prefer to keep important conversations for reference but clean up others regularly. You might decide to keep text conversations with family members but delete casual group chats after a few months. Others may archive conversations instead of deleting them. While iPhone's Messages app does not have a traditional archive feature like email does, you can use the search function to find old conversations even if they have scrolled out of view.
If you are switching phones or want to back up your text messages, you can use iCloud backup. When you set up iCloud backup on your iPhone, your messages are included in the backup. If you later restore from that backup on a new phone, your text message history will be restored as well. This process requires that you have an iCloud account and enough storage space in your iCloud plan.
For users who want to free up storage space quickly, deleting conversations with large numbers of photos and videos can have a noticeable effect. You can check how much storage your Messages app is using by going to Settings, then iPhone Storage, and scrolling to find Messages in the list. This shows you the total storage used by the app and all your conversations combined.
Practical takeaway: Periodically review and delete old conversations with photos and videos to keep your iPhone running smoothly and ensure you have storage space for new content.
Text messaging is generally a safe communication method when you follow a few basic precautions. One important rule is to never share sensitive personal information through text messages. This includes passwords, Social Security numbers, banking details, or answers to security questions. Even though text messages feel private because only you and the recipient see them, they can be intercepted or accessed by hackers if your phone is compromised.

Phishing is a concern with text messaging just as it is with email. Phishing messages appear to come from a legitimate source, such as your bank or a popular app, and ask you to click a link and verify information. These links often lead to fraudulent websites designed to steal your information. If you receive an unexpected text asking you to verify account information or click a link, do not do so. Instead, contact the organization directly using a phone number or website you find yourself, rather than using contact information from the suspicious message.
Be cautious about clicking links in text messages from people you do not know. Some links may install harmful software on your phone or lead to malicious websites. If a message seems unusual or suspicious, it is better to ignore it than to risk compromising your phone's security.
For conversations containing sensitive information, you might consider using additional security measures. Some messaging apps offer end-to-end encryption, which means even the service provider cannot read your messages. However, the standard iPhone Messages app does not offer the highest level of encryption for regular SMS messages, though iMessage does provide stronger encryption between iPhones.
Another privacy consideration is who has physical access to your phone. Someone who holds your unlocked iPhone can read all your text conversations. Using a strong passcode to lock your screen provides a first layer of protection. You can also use Face ID or Touch ID to add an extra security step when opening the Messages app specifically.
Practical takeaway: Treat text messages like any other form of communication—do not share sensitive information through them, be skeptical of unexpected links and requests, and keep your phone locked with a strong passcode.
If you own multiple Apple devices such as an iPad or Mac computer, you may receive text messages on those devices in addition to your iPhone. This happens through a feature called iMessage and SMS Forwarding. iMessage sends through the internet, so it works on any device connected to Wi-Fi or cellular data. This means you might read a text conversation on your iPad while your iPhone is in another room.

Text messaging etiquette varies depending on the situation and your relationship with the person you are texting. In professional settings, text messages are generally more formal and direct than casual texts with friends. You might use proper punctuation and complete sentences when texting your boss or a client, while texts with close friends might be more casual with abbreviations and fewer formalities.
Response time expectations also differ by context. In emergencies or urgent matters, people may expect a faster response to texts than they would to email. However,
