About one-third of US citizens (36%) have some type of prepaid mobile plan. They either pay in advance for data allowances and minutes or pay as they go and refill as needed.

Prepaid is a billing term for payment in advance.

You may also have heard other terms for prepaid mobile plans, such as pay-as-you-go (PAYG), pay-as-you-talk, etc.

What is a Prepaid Mobile Plan & How Does it Work?

A prepaid mobile plan is exactly what it sounds like: you pay in advance for a fixed amount of calls, text messages and data.

After the payment is made, you can use your assigned mobile services until you run out of balance.

Once you’ve used up the total value, you won’t be able to make any more calls, send text messages, or perform any actions that require data until you top-up or recharge.

Depending on the operator, the amount of assigned mobile services could expire after a certain period, most commonly after 30 days, however, there are year-long options available.

There is a calendar vector art on the left side of the image with a checked box on the first day of the month, with the text on the right describing how prepaid mobile plans require payment in advance at the start of each billing cycle.

Prepaid mobile plans are frequently offered by MVNOs (mobile virtual network operators), which rent out infrastructure from major MNOs (mobile network operators) like Verizon, AT&T and T-Mobile in the US.

This setup often results in cheaper options without the hassle of device installments or extra fees.

What is a Prepaid Mobile Phone?

The term prepaid also applies to mobile devices.

Prepaid mobile phones, also known as burner phones or go-phones, are mobile devices you buy without a contract, paying the full price up-front.

Mobile phone contracts are a vital part of postpaid mobile plans, but prepaid mobile plans generally avoid device contracts.

However, they offer deals such as multi-line discounts and special offers for using multiple telco services (landline, internet, wireless).

Who are Prepaid Mobile Plans Best for?

A prepaid mobile phone plan is the ideal choice for individuals who prefer greater control over their budget, or those seeking to lower the cost on their mobile phone bill.

An infographic showcasing the three primary target demographics for prepaid mobile plans. From left to right we can see an artistic "stick figure" representation of the main three groups: kids, seniors and travelers.

Prepaid Plans for Kids

A prepaid mobile plan is ideal for kids.

Parents can control the cost of giving their kids a mobile phone.

This is useful when it’s your child’s first phone and they haven’t yet demonstrated their ability to use it responsibly.

Prepaid Plans for Seniors

Seniors might not need an all-inclusive phone plan, since they often only use their mobile devices for calls and text messages.

They wouldn’t need a lot of data, so they could get by quite comfortably with a simple prepaid package, or even a pay-as-you-go plan.

    Common Deals and Offers

    Prepaid mobile plans involve paying upfront for a monthly (or yearly) package of data, text and minutes, with unused services expiring at the end of the period.

    In contrast, PAYG (pay-as-you-go) plans charge based on actual usage, offering more flexibility and less wastage.

    PAYG plans have a predefined tariff for minutes, texts and GB or MB of data.

    PAYG is a subset of prepaid plans with a usage-based billing model and longer validity for unused services – but, before making a decision, try to calculate the cost services per unit.

    An example offer of prepaid packages and PAYG plans could look like this:

The image contains three prevalent packages of prepaid mobile plans: pay-as-you-go plan with a fixed cost per call, text and gigabyte of data, a monthly prepaid package with a predefined amount of calls, texts and data, and a yearly prepaid package with a predefined amount of mobile services.

    We’ve already mentioned that MVNOs are the best, when it comes to great prepaid plans.

    Market Analysis

    In 2018, approximately 31.13% of US mobile users were using prepaid mobile services. Since then, the demand for unlimited data plans has led to a significant decline in prepaid users.

    Insights from March 2024 show that 45% of US mobile users  are using unlimited data plans.

    However, other studies indicate that 56% of unlimited data users in the US could save up to $268.44 annually by switching to prepaid plans or mobile plans with capped data.

    To explore this further, let’s look at the average revenue per user for a major MNO (mobile network operator) in the US, T-Mobile.

    A graph showcasing the average revenue per user of a major MNO in the US - T-Mobile. The graph contains quarter data from Q1 2013 to Q1 2024. We can deduct that the average revenue per user is more than $10 lower for prepaid mobile plans.

    In the first quarter of 2024, T-Mobile generated an average revenue of $37.18 per prepaid phone user in the United States.

    This is $11.61 lower than the average revenue for postpaid customers, which was $48.79.

    Mobile operators are trying to bridge the gap between prepaid and postpaid users by introducing unlimited prepaid data plans.

    They could have some limitations such as deprioritization and the inability to use your data as a hotspot, but it all depends on the carrier.

    It’s great to see that companies are starting to provide unlimited no-contract mobile plans, offering more options to mobile consumers.

    How Prepaid Billing Works

    Let’s go over the steps involved in prepaid billing:

    1. Usage: When the user is using mobile services, prepaid gateway is capturing the amount of services used and the user’s account information.
    2. Authentication: The payment gateway authenticates the user by sending information to the real-time billing system.
    3. Balance information: The real-time billing system responds with the user’s balance information, notifying the prepaid gateway of the user’s remaining prepaid balance.
    4. Amount used: Prepaid gateway keeps track of the amount of services used and forwards it to the real-time billing system.
    5. Balance update: The real-time billing system recalculates the user’s prepaid balance based on the amount of services used.
