What is a cellphone?
Small wireless device that has at least the same functions of a standard wired telephone but is smaller and more mobile. A cell phone requires a subscription to a service provider and requires either a prepaid or monthly billing setup. Generally, they have more functions than traditional land lines and need to be charged after a period of time. Also called mobile phone or mobile device.—BusinessDictionary.com

A mobile phone (also known as a cellular phone, cell phone and a hand phone) is a device that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station.—Wikipedia

A portable telephone that uses wireless cellular technology to send and receive phone signals. This technology works by dividing the Earth into small regions called cells. Within each cell the wireless telephone signal goes over its assigned bandwidth to a cell tower, which relays the signal to a telephone switching network, connecting the user to the desired party.—Dictionary.com

Cell phone increase in the Philippines
The use of mobile phones in the Philippines has brought better information access for farmers, broader citizen engagement and link to traffic data for taxi drivers, according to a new World Bank report. The country also witnessed one of the first uses of text messaging as a medium for social change during the EDSA II revolt in 2001 that led to the ouster of then President Joseph Estrada, the study cited. According to the report “Information and Communications for Development: Maximizing Mobile,” which was released on Monday, there were 101 mobile cellular subscriptions for every 100 people in the Philippines in 2011, a jump from 41 subscriptions for every 100 people in 2005. The report defined mobile cellular subscriptions as subscriptions to a public mobile telephone service using cellular technology, which provided access to the public switched telephone network. Postpaid and prepaid subscriptions were included. But it said that mobile subscriptions did not reflect actual mobile phone ownership since there could be multiple subscriptions. Worldwide, the number of mobile subscriptions grew from one billion in 2000 to more than six billion in 2011, of which nearly five billion were in developing countries, the report said. In 2011, 96 percent of the total mobile cellular subscriptions in the Philippines were prepaid. In 2010, mobile cellular network in the Philippines covered 99 percent of the population and 80 percent of households reported ownership of a mobile telephone. The World Bank cited the Philippines as an example in using mobile’s potential to strengthen accountability and transparency in public services and processes. In particular, it said that the Department of Education has worked with the Affiliated Network for Social Accountability in East Asia and the Pacific to set up a website that allowed the citizens to view significant statistics on local schools. The site, called checkmyschool.org, is a government-to-citizen online and mobile-based interactive tool that includes information such as budget allocations, teacher and textbook information and test scores for about a fifth of the 44,000 schools in the country, the report said. It is also an avenue for teachers and parents to express areas of concern that they feel should be addressed. The site, which seeks to improve education service delivery through transparent and accountable behavior by school staff, has improved community participation and vigilance and teacher behavior, the World Bank said. “These efforts are typically innovative because they often change the delivery or management of a conventional service or process,” the report said.
