Boost Mobile Phone Deals for Existing Customers in 2026

Existing Boost Mobile customers can qualify for phone upgrades, trade-in credits, financing and selected promotional prices. However, many of the lowest advertised prices require a plan change, an added line, advance service payments or an eligible trade-in. A deal being displayed on Boost’s website does not automatically mean it applies to an existing line.

Current customers should sign in to their Boost account before shopping because account-specific upgrade prices may differ from public new-customer offers. Boost currently advertises selected Apple and Android discounts with a limit of up to two promotional devices per order for eligible existing customers, but every offer has separate terms.

What Boost Mobile Phone Deals Are Available for Existing Customers?

The main Boost Mobile phone deals for existing customers fall into five categories:

• Promotional prices with an eligible premium plan
• Trade-in credits toward a new phone
• Standard phone upgrades
• Device financing
• Annual upgrades for qualifying Infinite Access customers

Some in-store promotions may also be available to “new or qualified existing customers.” Eligibility can depend on the account’s payment history, current plan, last discounted device purchase, location and available inventory.

Here is a general overview:

Deal type	Existing customers eligible?	Common requirement
Regular phone upgrade	Yes	Pay the current account-specific price
Online trade-in	Yes	Buy a new device and return an eligible old phone
In-store trade-in	Yes	Complete appraisal at participating store
Promotional phone price	Sometimes	Premium plan, added line or advance service payment
Free phone promotion	Limited	Trade-in, eligible plan or qualified activation
Device financing	Qualified customers	Credit approval or available financing option
Infinite Access annual upgrade	Eligible legacy-plan customers	12 consecutive payments and device return

Deals change frequently. Check the official Boost Mobile phone deals page and then sign in to view the offer attached to your line.

Current Boost Mobile Phone Promotions to Check

Boost currently advertises several discounted devices that may allow up to two per order for qualified existing customers. The public examples below are not guaranteed upgrade prices for every account.

Apple iPhone 16e

Boost advertises the iPhone 16e for as low as $49.99, reduced from its listed full price, with two months of the $60 Unlimited Premium plan paid in advance.

The public offer says the order limit can be higher for existing customers. However, other terms associated with selected versions of the promotion mention number-transfer or activation requirements.

An existing customer should confirm whether the deal is available for:

• An upgrade on the current line
• A newly added line
• A number transferred from another carrier
• A qualifying in-store trade-in

Do not change your plan or pay for service until the checkout page confirms that the promotional price applies to your account.

Apple iPhone 17

Boost currently lists a discounted iPhone 17 price with the $60 Unlimited Premium plan. The advertised savings and final price vary according to storage, inventory and promotion.

Existing customers may be allowed to purchase up to two promotional devices per order, but the Unlimited Premium plan requirement can substantially increase the total service cost.

Before accepting the discount, calculate the phone price plus the difference between your current plan and the $60 plan.

Apple iPhone 15

The iPhone 15 is another model Boost advertises at a discounted price with Unlimited Premium. It may provide better value than buying the newest iPhone if you do not need the latest processor or camera features.

Confirm whether the device is new, its storage capacity, and whether your existing account must change plans to receive the reduced price.

Samsung Galaxy A-Series Phones

Boost frequently promotes affordable Galaxy A-series devices, including free or heavily discounted models with eligible activation.

For example, selected promotions have offered a Galaxy A-series 5G phone after prepaying for two months of the $50 Unlimited+ plan. The exact model and eligibility can change.

Some store offers are available to new or “qualified existing” customers. Ask the store to check your line before charging a setup or activation fee.

Motorola and Boost-Branded Phones

Motorola moto g models and Boost’s Celero devices are commonly among its least expensive upgrade options. They may not have the cameras or processors found in premium phones, but they can provide:

• 5G connectivity
• Large displays
• Long battery life
• Expandable or generous storage
• Modern Android software
• Lower upfront costs

These phones may be a practical choice when an existing customer needs an immediate replacement without financing a flagship device.

Are Existing Boost Customers Eligible for Free Phones?

Some qualified existing customers may receive a free phone promotion, but Boost does not give every existing customer a free upgrade.

Free-phone offers commonly require one or more of the following:

• Adding a new line
• Moving to a more expensive plan
• Paying for multiple months of service upfront
• Trading in an eligible device
• Activating at a participating store
• Meeting account-specific upgrade requirements
• Selecting one of a limited group of phones

A phone advertised as “on us” can still involve sales tax, a device setup fee, plan payments or other initial charges. It may also require the customer to keep an eligible plan active.

Ask for a complete checkout summary showing:

• Device price
• Sales tax
• Setup or activation fee
• Required monthly plan
• Advance service payment
• Trade-in value
• Financing payment
• Total due on the purchase date

Do not assume a new-customer switcher offer applies to an existing line.

How to Check Your Boost Mobile Upgrade Deals

Account-specific pricing is usually the best way to find an offer that genuinely applies to an existing customer.

Follow these steps:

1. Sign in to your account through the Boost Mobile website or app.
2. Select the line you want to upgrade.
3. Open the device or upgrade section.
4. Review the phones available for that particular line.
5. Select a phone to display its complete price.
6. Check whether the offer requires a plan change.
7. Add a trade-in if you have an eligible device.
8. Review taxes, setup fees and service payments.
9. Compare the total with the phone’s unlocked retail price.
10. Complete the purchase only after verifying every requirement.

You can also visit a Boost store and ask an employee to check upgrade eligibility. Request a printed or on-screen cost breakdown before paying.

Boost Mobile Trade-In Deals

Boost now offers online and in-store trade-in programs. An existing customer can purchase a new device and exchange an eligible old phone for credit.

Online Trade-In

When buying a new phone online:

1. Select the trade-in option.
2. Enter information about the old phone.
3. Provide its IMEI and condition.
4. Review the estimated value.
5. Purchase the new device.
6. Wait for the trade-in kit.
7. Remove personal data and activation locks.
8. Return the old phone within the required period.

Boost applies the value as an account credit after inspecting the device. The final value can differ from the estimate if its model or condition does not match the submitted information.

Boost says the old device should generally arrive within 30 days of the new phone’s shipment. Returns received late can receive a lower value, while devices received after 60 days may not be accepted.

In-Store Trade-In

Participating Boost stores can inspect a phone and provide instant credit or access to selected trade-in promotions. Store credit may be applied to the new device or accessories but may not cover monthly service, taxes or certain fees.

A phone may be rejected if:

• It does not turn on
• It is reported lost or stolen
• The IMEI is blacklisted
• Find My iPhone or another activation lock remains enabled
• The model or condition differs from the information provided
• It still has an active Boost financing agreement
• It received a qualifying device discount too recently

Boost states that a current phone with active financing or a special device discount received within the previous nine months may be ineligible for its standard online trade-in program.

Infinite Access Annual Upgrade Program

Boost’s Infinite Access program is the most structured phone-upgrade option for eligible existing customers. Customers enrolled in a qualifying Infinite Access plan can become eligible for a newer device after making 12 consecutive monthly payments.

When eligible, the customer can select the upgrade through the Boost account or app and return the financed phone.

Important requirements may include:

• Twelve consecutive payments
• An account in good standing
• Returning the original financed phone
• Matching the phone’s IMEI with the finance agreement
• Removing all activation locks
• Returning the device in acceptable condition
• Paying for upgraded storage or a more expensive model

Eligible customers can generally select the latest qualifying iPhone or Galaxy S or Z-series device. Choosing additional storage or another premium model can increase the monthly payment.

Boost stopped offering the Infinite Access for Galaxy plan to new enrollments on June 30, 2026. Existing customers enrolled before that date may keep eligible credits and upgrade privileges as long as they comply with the terms.

Read the official Infinite Access upgrade instructions before returning a phone.

Boost Mobile Device Financing

Boost provides financing options for customers who cannot or do not want to pay the full device price upfront.

The company offers 0% APR financing on eligible phones for existing customers enrolled in an Infinite Access plan. Selected Apple products, including compatible watches and tablets, may also qualify for 36-month 0% financing.

Other customers may have access to third-party financing, subject to approval. A down payment may be required.

Check:

• Length of the payment agreement
• Required down payment
• Interest rate or APR
• Monthly device payment
• Plan requirement
• AutoPay requirement
• Taxes due at checkout
• Early payoff rules
• Device-unlocking policy
• Consequences of canceling service

“No contract” usually describes the wireless plan. A customer financing a device still has a separate obligation to pay the remaining device balance.

Should You Change Plans to Get a Phone Deal?

Boost may require Unlimited+ or Unlimited Premium to receive its best phone prices. Changing plans can reduce the device price but increase the total cost over time.

For example, moving from the $25 plan to the $60 plan costs an additional $35 per month before taxes. Keeping the higher plan for one year adds approximately $420 to the service cost.

A $300 phone discount would not create real savings if the required plan costs $420 more and you do not need its extra features.

The $60 Unlimited Premium plan currently includes:

• Unlimited talk and texts
• 50GB of premium high-speed data
• Mobile hotspot
• Global Talk & Text
• North America Connect
• 5GB of eligible Canada and Mexico roaming data

The upgrade may be worthwhile if you already want these benefits. Otherwise, compare the full cost with buying an unlocked phone while keeping your existing plan.

Can You Buy an Unlocked Phone Instead?

Yes. Buying an unlocked device from Apple, Samsung, Google, Motorola or another reputable retailer can sometimes be cheaper than accepting a carrier promotion.

An unlocked phone gives you greater freedom to:

• Keep your current Boost plan
• Avoid a required premium plan
• Switch carriers later
• Compare retailer discounts
• Trade the phone elsewhere
• Sell it independently

Before purchasing, enter the IMEI or model in Boost’s compatibility checker. The phone should support Boost’s assigned network, VoLTE and required 4G LTE or 5G bands.

How to Get the Best Existing-Customer Deal

Use these tips before upgrading:

Check Your Online Account First

Public promotional pages often emphasize new-customer offers. Signing in reveals the prices available to your specific line.

Compare Online and In-Store Offers

Boost stores may have trade-in deals unavailable online, while the website may waive or reduce certain store fees. Compare both totals.

Ask About Plan Requirements

A discounted phone can become expensive if it forces you to maintain a plan you do not need.

Calculate the Total Cost

Add the device price, taxes, setup fees, advance plan payments and increased monthly service cost.

Check Your Trade-In Elsewhere

Compare Boost’s offer with the manufacturer, major retailers and reputable resale services. Boost account credit may be less flexible than cash.

Wait for Seasonal Promotions

Back-to-school, holiday and new-phone-launch periods may provide better opportunities. However, do not delay replacing a phone that is unsafe, damaged or no longer receiving important security updates.

Keep Screenshots and Receipts

Save the offer terms, order confirmation and trade-in estimate. These records can help if a promotion or account credit is applied incorrectly.

Existing Customer vs New Customer Deals

New customers usually receive the most aggressive Boost promotions because the company wants to attract new lines and transferred numbers.

Offer feature	Existing customer	New customer
Standard upgrade	Yes	Not applicable
Trade-in credit	Yes	Yes
Account-specific price	Yes	No existing account
Free switcher phone	Usually limited	Commonly available
Port-in promotion	Requires adding/transferring a line	Often eligible
Infinite Access annual upgrade	Eligible enrolled customers	Requires qualifying enrollment
Promotional order limit	Sometimes up to two devices	Commonly one device

Existing customers should focus on upgrade pricing, trade-ins and account-specific promotions rather than assuming they qualify for every public offer.

For comparison, see our guide to free phone deals for new customers.

Frequently Asked Questions

Does Boost Mobile give existing customers free upgrades?

Not automatically. Some qualified accounts may receive a free or discounted phone through a plan promotion, trade-in or Infinite Access upgrade.

How do I know whether I am eligible for an upgrade?

Sign in to the Boost website or app, select your line and open the upgrade section. A Boost store or customer service agent can also check the account.

Can an existing customer get the discounted iPhone 16e?

Some public Boost offers allow up to two promotional devices for eligible existing customers, but plan, activation, advance-payment or port-in terms may apply. Confirm eligibility while signed in.

Can I trade in a Boost phone that I am still financing?

Generally, a phone with an active financing agreement is not eligible for the standard trade-in program. Infinite Access customers must follow their separate annual-upgrade process.

Will upgrading change my phone number?

No. A normal upgrade replaces the device on the existing line. Keep the current SIM or follow Boost’s eSIM or activation instructions.

Do I have to change my Boost plan when upgrading?

Not for every upgrade. However, many promotional prices require the $50 Unlimited+ or $60 Unlimited Premium plan.

Does Boost charge an upgrade fee?

Online and store charges can differ. Taxes, device setup fees, SIM charges or advance service payments may apply. Review the complete total before purchasing.

Final Thoughts

The best Boost Mobile phone deals for existing customers include account-specific upgrade prices, online or in-store trade-in credit, selected premium-plan promotions and annual upgrades for eligible Infinite Access customers.

Boost does not guarantee every existing customer the same discount. Sign in before shopping, verify whether the offer applies to your current line and calculate the complete cost of any required plan change. In many cases, buying an unlocked phone and keeping a less expensive plan can save more than accepting a large device discount tied to premium service.
