Just as random example a Nokia mobile phone.
To look at today's cellphones we'll take some features of the Nokia 3360.
Talk time and Standby time:
Talk time and Standby time depend on battery type, network settings and usage.
Talk time and Standby time in Digital:
The talk time is 90-300 minutes and the standby time is 108-360 hours.
Talk time and Standby time in Analog:
The talk time is 90-150 minutes and the standby time is 18-45 hours.
Preference settings/Profiles:
You can customize the way your phone works. You can set your own preferences for the items:
Ringing options, Ringing volume, Ringtones, , Profile name, Warning tones, Message alert tone, Vibrating alert and Keypad tones.
The Nokia 3360 phone comes with five profiles:
Normal (default setting), Silent, Meeting, Outdoor and Pager.
You can customize any of the profiles. If at any time you want to return to the original settings, you can do so.
Caller ID:
Caller ID displays the telephone number of an incoming caller on your cellphone screen. If the number is one that you've already entered in memory, caller ID will also show the caller's name. By alerting you to who is on the line, you can return non-urgent calls at a later time, as well as be prepared to accept important calls.
Conference Call:
While in a call, you can call another number and add a third party to the call.
The conference call feature varies based on wireless systems. Contact your service provider for details
Voice mail:
To use voice mail, you must sign up for the feature with your wireless service provider.
Then, when you don't answer, incoming calls are directed to voice mail, to retrieve later.
Most cellphones displays will indicate if you have new messages.
Call forwarding:
Call forwarding redirects all of your incoming calls to another number if your cellphone is turned off or already in use. This is particularly handy when you'll be away from your cell phone for an extended period or if you are outside of your calling area.
Mobile messaging:
Messaging features are network dependent services.
You can send and receive text messages directly with other compatible phones, or using an email address.
Also have a look at the multimedia messaging of Nextel.
Text messages:
With the text message network service, you can send and receive short text messages. You can also send and receive messages that contain a person’s name and/or number (a “business card”).
To send text messages, your cellphone and the phone you're sending the message to must have text message capability. Or, you can ask the service provider to convert the message to other formats such as e-mail and fax.
The maximum length of a text message is 160 characters. Your phone has space for up to 30 text messages, depending on the length of each message.
The maximum length of a text message differs, depending on the capabilities of the network from which it originated. Also, the text messages may appear different at times. This happens because messages can originate in networks other than your own.
You can write a message two ways: using standard (ABC) text input or using predictive text input.
Standard text input is the default mode for text entry. To enter a letter using standard input, find the letter on the keypad and press the appropriate key. You may need to press the key more than once to reach the correct letter.
You have the option of using predictive text input, which uses a built-in dictionary to speed up the process of entering text.
The dictionary support 7 languages: English, Spanish, French, Portuguese, Hebrew, Russian ans Chinese.
Each time you press a key the phone compares the word you have entered so far with the words in the database and selects the most likely word.
So you can write by pressing one key per letter, instead of two or three with an ordinary keypad.
You can also input new words and names into the database.

Chat rooms:
You can have a direct conversation with another person using the chat feature. Chat has distinct advantages over text messaging, such as faster send and reply, as well as direct, uninterrupted communication with your chat partner.
To use Chat you must subscribe to text messaging, which is network dependent. Contact your service provider for more information.
Email messages:
You can use your phone to send and receive e-mail messages. The e-mail feature is not available from all service providers. Check with your service provider for availability.
Reminders or Notes:
Reminders and notes help you keep track of important events or tasks. A reminder can have a date, time and alarm attached to it.
You can also send and receive reminders and notes in the same way you send and receive business cards, by text messaging (SMS) or by Infrared.
Phone card:
A phone card can be used when you dial long distance calls. First you must save the phone card information in the phone. The phone can store information for a maximum of four calling cards.

Phone book:
Up to 200 names and associated phone numbers can be stored in your phone book. In addition, the phone book can store up to two numbers per name, and a text entry, such as a postal address or an e-mail address.
Games:
Pairs 2, Snake 2, Space impact.
Ringtones:
You can set the ringing tone to a specific sound or tune to personalize how the phone rings.
You can also download up to 10 ringtones to replace the personal entries in your list ringtones. Ringtones can be ringing sounds or short tunes. For details about this network service, contact your wireless service provider.
Calculator:
Your phone's calculator adds, subtracts, multiplies, divides, and converts currency.
InfraRed(IR):
The Nokia 3360 phone can send and receive certain types of data by way of the phone’s infrared (IR) port. This is a wireless transfer, so you don’t need a cable or additional software.
To connect using IR, the device with which you want to connect must comply with Infrared Data Association (IrDA) requirements. Transmission and reception must be to or from a compatible phone or device (for example, another phone, computer, or handheld device).
The Nokia 3360 phone is a Class 1 Laser Product.
IR distance: the preferable distance between the two devices in infrared connection is from 3 inches to a maximum of 3 feet. There must be no obstructions between the two devices. The IR ports of the two devices must point to each other.
You can use IR to send and receive phone book entries (business cards) and reminder notes.
SIM Card:
SIM = Subrscriber Identity Module. Every GSM Nokia cell phone has a SIM card. It's a memory & processor, on a small piece of cardboard, holding your personal data and applications.
You can use this SIM card in any other GSM cell phone. Just pop it out of your phone and put it in any other GSM phone. This is very handy if your battery has quit. Put the SIM card into someone else's phone. The same thing with getting a new GSM phone. Your data must be stored on the SIM card before you can
use/access it on other GSM cell phones.
