Mobile phone charms (also cell phone charms, phone danglers, phone lanyards and phone straps) are charms that are connected to a mobile phone using a small strap, a band knotted with a Cow hitch knot, or lanyard.
 Many phones have a loop hole through which a strap can be attached.
 In Japan they are known as "keitai straps" (携帯ストラップ ) .
 Phone straps have now become a cultural phenomenon beyond their basic utilities, and they may be decorated or themed with famous characters such as animation heroes or "Hello Kitty".
 Phone straps may also have additions to add additional functions such as detecting ghosts, carrying medicine pills or mobile gardening.
Global System for Mobile Communications (GSM) services are a standard collection of applications and features available to mobile phone subscribers all over the world.
 The GSM standards are defined by the 3GPP collaboration and implemented in hardware and software by equipment manufacturers and mobile phone operators.
 The common standard makes it possible to use the same phones with different companies' services, or even roam into different countries.
 GSM is the world's most dominant mobile phone standard.
A prepay mobile phone (also commonly referred to as pay-as-you-go, pay-as-you-talk, pay and go, go-phone or prepaid) is a mobile phone for which credit is purchased in advance of service use.
 The purchased credit is used to pay for mobile phone services at the point the service is accessed or consumed.

 Users are able to top up their credit at any time using a variety of payment mechanisms.

Mobile phone overuse (Mobile-phone addiction or problem mobile phone use) is a dependence syndrome seen among certain mobile phone users.
 Some mobile phone users exhibit problematic behaviors related to substance use disorders.
 These behaviors can include preoccupation with mobile communication, excessive money or time spent on mobile phones, use of mobile phones in socially or physically inappropriate situations such as driving an automobile.
 Increased use can also lead to increased time on mobile communication, adverse effects on relationships, and anxiety if separated from a mobile phone or sufficient signal.
Mobile phone tracking is the ascertaining of the position or location of a mobile phone, whether stationary or moving.
 Localization may occur either via multilateration of radio signals between (several) cell towers of the network and the phone, or simply via GPS.
 To locate a mobile phone using multilateration of radio signals, it must emit at least the roaming signal to contact the next nearby antenna tower, but the process does not require an active call.
 The Global System for Mobile Communications (GSM) is based on the phone's signal strength to nearby antenna masts.
The Siemens S40 is a mobile phone.

 At one time, half the world had mobile phones.
 The articles in 2007-2008 were slightly misleading because the real story at the time was that the number of mobile phone subscriptions had reached half the population of the world.
 In reality many people have more than one subscription.
 For example, in Hong Kong, Italy and Ukraine, the mobile phone penetration rate has passed 140% (source wireless intelligence 2009).
 By 2009 even the number of unique users of mobile phones had reached half the planet, when the ITU reported that the subscriber number was to reach 4.6 billion user which means 3.8 billion activated mobile phones in use, and 3.4 billion unique users of mobile phones.
 The Mobile Internet data connections are following the growth of mobile phone connections albeit at a lower rate.

 According to the BBC, there are now (2010) over 5 billion mobile phone users in the world.
