Postpaid mobile phone

Postpaid mobile phone is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Postpaid mobile phone rather than just read about it. In short: The postpaid mobile phone is a mobile phone for which service is provided by a prior arrangement with a mobile network operator or mobile virtual network operator. In this type of payment plan, the customer is billed at the end of each month according to their use of mobile services during that month.

Key takeaways

Postpaid mobile phone belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Postpaid mobile phone to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Postpaid mobile phone from memory before moving on to harder problems.

Reference excerpt

The postpaid mobile phone is a mobile phone for which service is provided by a prior arrangement with a mobile network operator or mobile virtual network operator. In this type of payment plan, the customer is billed at the end of each month according to their use of mobile services during that month. The alternative billing method is a prepaid mobile phone, where a user pays in advance for credit that is then consumed by use of the mobile phone service.

Billing plans Typically, the customer's contract with a specifies a limit or "allowance" of minutes, text messages etc., and the customer will be billed at a flat rate for any usage equal to or less than that allowance. Any usage above that limit incurs overage charges. Postpaid service for mobile phones requires two components in order to make the "post-usage" model viable:

Credit history and contractual commitment. This is the basis on which the service provider is able to trust the customer with paying their bill when it is due and to have legal recourse in case of non-payment. Service tenure. Most postpaid providers require customers to sign long term (1–3 year) contracts committing to use of the service. Failure to complete the term would make the customer liable for early termination fees.

Usage

Europe A 2010 survey of university students in 10 European countries found that 42% used postpaid plans and 13% had both postpaid and prepaid service.

United States and Canada The United States and Canada are examples of countries dominated by postpaid providers, including AT&T, T-Mobile, and Verizon in the US and Bell, Rogers, and Telus in Canada, among others. In the US a smaller market has been captured by prepaid providers such as Boost Mobile, Metro by T-Mobile, Cricket Wireless, TracFone, and Ting, which use postpaid providers networks (e.g. Cricket runs on AT&T's network).

South Africa In South Africa, about 20% of mobile phone users use postpaid contracts for voice and data service.

Worked examples

Example 1 — a first encounter with Postpaid mobile phone

Start with the simplest possible case. Write down what Postpaid mobile phone claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Postpaid mobile phone before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Postpaid mobile phone ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Postpaid mobile phone

In research: Postpaid mobile phone appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Postpaid mobile phone in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Postpaid mobile phone is common in secondary-school and first-year university syllabi. It links to neighbouring topics Mobile telecommunication services, so understanding it makes those chapters shorter.
In everyday life: Look for Postpaid mobile phone outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
