Smartphones provide the ability to get answers really fast. In some situations, a student may not ask for clarification to a question he or she has in an open classroom—because they can use their smartphone to get the answer they're looking for.

• Communication

Mobile phones provide the means to communicate with friends, family, coworkers, and indeed most of the world's population instantly. Unlike previous communication devices, they can be on hand for the caller at all times and used in any place where there is a signal.

•  Small and Convenient

They fit easily into your pocket or bag. They don't weigh much. There are inexpensive models available for those with a limited budget. If the battery gets low, you can recharge them in your car, plug them into an electrical outlet using a cable, or even charge them wirelessly in some cases.

• Photos and Video

Many people don't even own a camera nowadays because their phone has all the image and video capturing capability that they require. Once the media has been captured, it can be sent to others via email, messaging, or Bluetooth; or posted on the internet with just a few clicks. Many phones also offer extras, such as photo editing.

• Texting

Text messaging (also known as texting) enables people to communicate with short written messages. Originally, phones used SMS technology, allowing the sending of letters, numbers, and symbols, but more recently, MMS technology has allowed multimedia, such as photos and videos, to be sent too. Texting is a great way to send someone an important instant message, as, unlike email, people are more likely to read their texts straightaway.

• Fashion and Self-Expression

Choosing which model of phone to carry, customizing things like the ringtone, or buying a more personal phone cover have all become a means of self-expression for mobile phone owners, informing others what sort of person you are.

• Entertainment

As long as you have your mobile phone, there is no reason to get bored. There is a multitude of games to download and play; you can read an online article or get involved with social media to pass the time. Smartphones allow video watching, as well as listening to radio, podcasts, or music. Plus, if you attend a real-life event, you can often store your ticket on your phone to display at the door.

• Notes and Reminders

Whether it's a shopping list, an important password, or a complicated set of instructions that would be difficult to memorize, mobile phones are a great way to carry notes and reminders. These don't always have to take the form of text or numbers either; you can also use photos, audio, or video to record important information for later use.

• Video in Real-Time

Many people now like to see the person that they are talking to, as well as hear the sound of their voice. Live video chat makes this possible. The real-time video also enables the live streaming of live events across the internet, as well as to other phones and devices.

•  Calendars and Organization

Mobile phones are great devices for organizations, and their calendars are an excellent way to manage a busy schedule. Your phone will alert you when you have a doctor's appointment, it is a loved one's birthday, or simply help you to organize your daily work tasks and personal schedule.
