Prepaid mobile phone

Typical signs showing where refills can take place.

A prepaid mobile phone (also commonly referred to as pay-as-you-go, pay-as-you-talk, pay and go, or prepaid wireless) 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. If there is no available credit, then access to the requested service is denied by the mobile phone network. Users are able to top up their credit at any time using a variety of payment mechanisms.

The alternative billing method (and what is commonly referred to as a mobile phone contract) is the postpaid mobile phone, where a user enters into a long-term (generally lasting 12, 18, or 24 months) or short-term (also commonly referred to as a rolling contract or a 30-day contract) billing arrangement with a mobile network operator or carriage service provider (CSP).

"Pay-as-you-go", "PAYG", and similar terms are also used for other non-telephone services paid for in the same way.

Overview of the prepaid service

A prepaid mobile phone provides most of the services offered by a mobile phone operator. The big difference is that with prepaid phones, payment for service is made before use. As calls and texts are made, and as data is used, deductions are made against the prepaid balance amount until there are no funds remaining (at which time, service is no longer available). A user may avoid such a break in service by making payments to increase the remaining balance.

Methods of payment:

Credit purchased for a prepaid mobile phone may have a time limit – for example, 90 days from the date the last credit was added. In these cases, customers who do not add more credit before expiration will lose their remaining balance.

There is no compulsion on a prepaid mobile phone user to top up their balance. To maintain revenues, some operators have devised reward schemes designed to encourage frequent top-ups. For example, an operator may offer some free SMS to use next month if a user tops up by a certain amount this month.

Unlike postpaid phones, where subscribers have to terminate their contracts, it is not easy for an operator to know when a prepaid subscriber has left the network. To free up resources on the network for new customers, an operator will periodically delete prepaid SIM cards which have not been used for some time, at which point, their service (and its associated phone number) is discontinued. The rules for when this deletion happens vary from operator to operator, but may typically occur after 6 months of non-use.

By 2003, the number of prepaid accounts grew past contract accounts, and by 2007, two thirds of all mobile phone accounts worldwide were prepaid accounts.

History

The history of the prepaid mobile phone begins in the 1990s, when larger markets were being sought after by the mobile phone operators. Before this date, all mobile phone services were offered on a post-paid basis, which excluded people with a poor credit rating.

One of the first pre-paid card was called "Mimo" and was launched by TMN the Mobile Phone Operator of Portugal Telecom in September 1995.[5] In 2006 Swisscom celebrated a ten-year's success story with its product and service "NATEL(R) easy" which also holds a patent on the topic "Prepaid mobile subscriber identification card and method implemented thereby".[6][7]

Prepaid versus postpaid mobile services

Advantages of prepaid

A prepaid plan may have a lower cost (often for low usage patterns e.g. a telephone for emergency use) and make it easier to control spending by limiting debt and controlling usage.[8] They often have fewer contractual obligations – no early termination fee, freedom to change providers, plans,[9] able to be used by those unable to take out a contract (i.e. under age of majority). Depending on the local laws, they may be available to those who do not have a permanent address, phone number, or credit card. This makes them popular amongst students away from their home towns and also travellers. Additionally, they are popular with parents who wish to have a way to stay connected with their college age students but do not want the surprise of an unexpected and lofty bill.

Disadvantages of prepaid

Sometimes, pay-as-you-go customers pay more for their calls and SMS messages, and in some cases they are limited in what they can do with their phone – calls to international or premium rate numbers may be blocked, and they may not be able to roam. These limitations are usually the results of a system deficiency whereby the prepaid system used by the wireless carrier as technology has evolved to the place where all this is easily managed by triggers or APIs to 3rd-party solution providers (data, international LD, content, roaming). Current models being deployed by wireless carriers today are capable of setting the price points for all services on an individual basis (via packages) such that higher pricing is a marketing decision. The days of higher pricing being due to more expensive network costs are gone.

Churn

As described above, prepaid accounts require that a subscriber have funds in the account to make outgoing calls (except emergency calls, which are always allowed). In the US, incoming calls are also barred, while in some other countries, a prepaid mobile with zero balance may still receive calls and texts.

This results in an "on/off" or "all or nothing" proposition for the prepaid service providers and their clients (that is, the account either has enough credit to use the phone, or it does not). Some operators (for example, Orange) allow their pre-pay customers to have a small negative balance to allow short calls or texts when the customer's credit has been completely used. This is then deducted when the customer next adds more credit.

The time most likely for a prepaid customer to switch to a different service provider is when the prepaid account reaches a "zero credit balance". Like other service providers, mobile service providers losing a mobile account call it "churn".

Prepaid mobile phones and roaming

In the early years, prepaid mobile phones could only be used within the operator's network from whom the customer purchased the phone. It was not possible to roam onto other GSM networks when using the phone abroad. This was because the operator had no way to bill calls in real time from another network.

However, most prepaid phones now offer roaming using one of the following methods:

Privacy rights and prepaid mobile phones

As of July 2013, at least 80 countries globally (including 37 on the African continent) have mandated, or are actively considering mandating, the registration of prepaid SIM users.[10]

The reason is a concern of police and security agencies that anonymous use of prepaid mobile services facilitates criminal or terrorist activities.

Prepaid phone users can be anonymous for two reasons:

While there is no doubt that criminals and terrorists use prepaid SIM cards to help stay anonymous and avoid easy detection, to date there has been no empirical evidence to indicate that:

1) Mandating the registration of prepaid SIM users leads to a reduction in criminal activities; and

2) The lack of any registration of prepaid SIM users is linked to a greater risk of criminal or terrorist activities.

In fact, a publicly available policy assessment report from Mexico showed that mandatory SIM registration introduced there in 2009 had failed to help the prevention, investigation and/or prosecution of associated crimes. As a result, policymakers decided to repeal the regulation three years later.[10]

A prepaid phone specifically purchased to be used briefly and then replaced is known colloquially as a burner phone or burner. A Los Angeles technology company currently offers a mobile application of the same name that replicates this functionality for a smartphone.[11]

International prepaid mobile phone branding

In an effort to differentiate the prepaid from post-paid service for their customers, CSPs have branded prepaid services differently from the post-paid services. A variant of post-paid service has emerged in recent years that comes closer to the prepaid service, by offering a "pay monthly" contract.

Prepaid phones and SIMs in the United Kingdom are known as "Pay as you go".[12][13]

Usage

Usage of prepaid cellphone service is common in most parts of the world. Around 70% of customers in Western Europe and China use prepaid phones with the figure rising to over 90% for customers in India and Africa.[14] 23% of cellphone users in the United States were using prepaid service as of 2011, a share that's expected to rise to 29% by 2016.[15] Prepaid SIM cards are also becoming a variation of the traditional prepaid cellphone plans. Rather than needing to purchase an entirely new phone, existing phones can be used by simply replacing the SIM card within the device.[16]
