AT&T, T-Mobile, Verizon, and cable customers are overpaying due to loyalty and other mistakes

We just survived another financial reporting season, where every carrier made sure to let you know it is looking out for you. Of course, a company putting a customer's interests before its own bottom line would likely go out of business. 

It's crucial to be mindful of that. A new report reveals that customers of AT&T, T-Mobile, Verizon, Xfinity, Spectrum, Cox, and Optimum are all paying more than they should.

Trust and loyalty: the cardinal sins

According to wireless price comparison website Save On Wireless, customers often overpay simply because of the confusion created by carrier market-speak.

After analyzing over 84,000 postpaid plans and deals in Q1 2026, the site identified exactly what's inflating those bills.

Their first discovery was that free phones cost $1,184 more in the long run than partially discounted devices. These deals are usually tethered to the most expensive plans and require long-term commitments.

On the other hand, partially discounted devices are available to customers on optimally priced plans, offering much better overall value.

The study also found that new customers save more than existing customers. Familiarity breeds contempt, or maybe a smaller budget. Like people, carriers tend to take you for granted the longer you stay.

The bulk of the promotional budget is typically allocated to customer acquisition rather than retention. New customers enjoy higher trade-in credits, lower plan pricing, waived activation fees, additional benefits such as gift cards, and offers to clear existing balances with their old carriers.

On average, existing subscribers pay $4.83 more per line every month than new customers on identical plans.

In some cases, an old carrier may offer value that another carrier might not be able to match, such as legacy pricing, free lines, or corporate discounts.

Savings tips

Of course, carriers aren't out to get you. Telecom providers offer numerous ways to save, but customers should know where to look.

By keeping an existing device for too long in the hopes of reducing the annual cost of ownership, customers forfeit the higher trade-in credit that a more recent device would get.

For instance, owners of iPhone 12 and later models could get $830 toward an iPhone 16. However, waiting just one more year for the iPhone 17 launch caused that trade-in value to plummet by as much as $480.

Another way to save is to be on a family plan, regardless of whether you are sharing a house with your actual family. Friends, siblings, and other adults living under the same roof can save up to $46.25 per line every month compared to individual plans.

Plan costs usually go down as more lines are added, and the savings add up over time.

Lastly, combining wireless and internet service can shave $480 in the first year of service.

It's easy to get swept up in marketing campaigns and lose sight of what you are signing up for. Carriers have even sued each other for misleading customers with their savings claims.

Getting to the bottom of discount pledges may be overwhelming for the average customer, but a little foresight can help you save thousands over the standard commitment period of 36 months.

Know what you want

At the end of the day, many AT&T, T-Mobile, and Verizon postpaid customers in particular are usually aware that cheaper options are available. They stay put because they are willing to pay a premium for superior network coverage and customer service.

While it's smart to cut the bloat from your bill, the most expensive carrier isn't always the wrong choice, as long as you are making an informed decision.

While carriers have sporadically cut rates, a full-blown price war hasn't materialized. This has led to an increased emphasis on creating the illusion of value, rather than creating actual value.
