# Mobile phones in prison

In most jurisdictions, prison inmates are forbidden from possessing mobile phones due to their ability to communicate with the outside world and other security issues. Mobile phones are one of the most smuggled items into prisons. They provide inmates the ability to make and receive unauthorized phone calls, send email and text messages, use social media, and follow news pertaining to their case, among other forbidden uses.

## Reasons cell phones are prohibited

Security concerns are often cited for why cellphones are prohibited in prisons.
Cellphones in prisons have been used to organize work stoppages for prison labor between prisons. Forced penal labor in the United States is a common practice.
In the United States, prison phone calls represent one of the few ways that prisoners can connect with family and loved ones in the outside world. However, these calls can be prohibitively expensive, a situation which has sparked controversy in light of the fact that they represent a source of profit for private prisons. Some have argued that this profit motive plays a key role in cell phone bans in prisons.

## Methods of smuggling

Most mobile phones are smuggled in by prison staff, who often do not have to go through security as rigorously as visitors. Security of staff is often less intense because this would be time-consuming on the part of the staff, and unionized prison employees are paid for this time, which increases the overall cost of operations. Additionally, prison staff are often reluctant to search their co-workers thoroughly to avoid workplace tension and morale issues.
More rarely, mobile phones are smuggled in by visitors, who must undergo tougher security checks, by inmates who are granted temporary leaves of absence, or by outsiders who establish contact with inmates alongside the prison fence and/or deliver them using drones.
Once inside prison walls, the devices end up in the hands of inmates who purchase them with cash, which is also contraband in most prisons. Black market prices vary by prison and can be up to US$1000.
Certain models of mobile phones are particularly popular among prisoners due to their compact size, ease of concealment, and minimal metal components that help them evade detection. Phones such as the Zanco Tiny T1, Beat the Boss Mini Phone, and Nokia 105 are among the most frequently smuggled devices in UK prisons.

## Uses by prisoners

While some prisoners use their mobile devices simply for harmless communication or web browsing, others use them for criminal activity. These may include gang control, taunting witnesses, planning escapes from custody, or arranging other serious crimes.
Prisoners may also use smartphones to gather intelligence on prison staff and coordinate clandestine activity within the facility.
Not all inmates use mobile phones for harmful purposes. Many inmates use them to hold conversations with family and friends.

## Combating mobile phones in prisons

Laws have been passed in various jurisdictions, placing penalties on inmates who possess mobile devices as well as staff who smuggle them in. Inmate penalties range from loss of privileges and behavior credits to additional sentencing. Staff penalties range from disciplinary action to job loss to criminal charges.
Some places are using an experimental technology of managed communications that blocks the communications of inmates while continuing to allow that of others.
In 2017, American company Securus Technologies announced an investment of more than $40 million in "Wireless Containment Solutions," a system that creates a local cellular network inside a prison requiring all phones on the network to be screened and approved.
