Boost Mobile Promo Code valid in October 2026

Boost Mobile promo codes sit alongside plan-linked phone savings, service credits and trade-in offers. The phone, plan and customer type can determine which savings apply. A low handset price can be tied to a qualifying plan or an eligible number transfer, rather than a code.

This guide was last reviewed in fall 2026. The live coupons and prices listed above are updated automatically and take precedence over any example described in this guide.

Applying a code to an eligible purchase

For a Boost Mobile coupon code listed on Discoup, copy the code, choose the purchase covered by the offer and continue to checkout. The code may be entered at checkout; enter it exactly as supplied and apply it. Before submitting payment, the order summary should show the expected saving.

Some device and plan deals apply based on their eligibility conditions instead of a code. In the cart, Boost Mobile states that promotional discounts have been applied and that taxes, fees and other applicable discounts will be calculated at checkout. The cart separates the amount due today from the monthly bill total.

The purchase requirement matters as much as the code: a phone offer can require a particular service plan, and a switching offer can require an eligible number transfer. A Boost Mobile voucher code may also be limited by customer status, eligible devices, account or line limits, channel and offer duration.

According to Boost Mobile's billing help, it accepts Visa, Mastercard, American Express and Discover, although it may be unable to process cards from some financial institutions; prepaid debit and credit cards are currently not accepted on boostmobile.com.

Phone offers and customer eligibility

Phone deals tied to service can discount a phone when the purchase adds a new line with an eligible tenured number transfer and prepaid service on the eligible plan. The terms of one such deal also exclude network-affiliated ports and limit the promotion to one device per account; taxes, activation and government fees are extra, and the deal is available for a limited time while supplies last and subject to change without notice.

New-customer, new-line and upgrade offers describe different purchases. A Boost Mobile activation promo code may be attached to a new account or qualifying activation; existing customers have a separate device-upgrade route. Online offers and participating-store offers can use different purchase requirements.

Boost Mobile's deals include plan promotions, selected phone discounts, family-plan savings, student offers and in-store offers. Some phone discounts require Unlimited+ or Unlimited Premium with number transfer, while multi-month offers use service prepayment. The price of the device and the recurring plan charge are separate parts of the purchase.

AutoPay and multi-month service offers

Boost Mobile's plan pages describe an AutoPay discount included in the price of eligible Unlimited, Unlimited+ and Unlimited Premium plans, with a higher monthly price when AutoPay is turned off. According to Boost Mobile's billing help, some account types and plan offers require AutoPay.

Boost Mobile's multi-month offers give special prices on select new devices when customers pay for several months of service upfront. Under those offer rules, prepaid service appears as monthly payment credits during the covered period. After that period, the plan and payment stay the same, but the prepayment credits end.

Customers who received a special device discount must stay on an eligible plan until they qualify for a device upgrade. Eligible additional lines can still receive multi-line discounts during service prepayment, so these two benefits can apply together under that program's conditions.

An ordinary early bill payment works differently: it becomes account credit applied to the payment on the normal due date. It is the multi-month offer, with its selected device and service requirements, that provides the special device price.

Trade-ins and device financing

For an online trade-in, the initial value is an estimate based on the phone and its stated condition. Boost Mobile applies the final value as account credit after receiving and validating the device. A different condition, an incorrect model or IMEI, or late arrival can reduce the value.

According to Boost Mobile's in-store trade-in terms, an eligible trade-in at a participating store can provide instant credit toward a new phone and accessories or an exclusive offer on a specific new promotional phone. Under the in-store trade-in terms, that credit cannot be used to pay taxes, fees or monthly service. Online account credit and in-store purchase credit therefore have different uses.

Boost Mobile's financing help describes Affirm financing and direct Boost Mobile financing, with eligibility depending on the device and plan. According to that financing help, direct interest-free arrangements cover select Apple devices such as iPads and Apple Watches, plus phone purchases by existing Infinite Access customers; other financing arrangements can require a down payment. Under the direct financing terms, AutoPay is required and device taxes are applied at checkout.

According to Boost Mobile's financing help, direct device installments appear on the regular monthly service bill, while Affirm handles its device payments separately from Boost Mobile service and feature payments. According to Boost Mobile's financing help, financing spreads out payments on a schedule; the promotional device price and trade-in credit are separate mechanisms.

Referral credits and multi-line savings

Boost Mobile's referral program awards bill credits to qualifying customers when a referred friend opens an eligible new account and stays active for at least 30 days. The referrer's account must also be active, and the referrer must be the single or primary account holder and have been a Boost Mobile customer for at least 30 days before submitting referrals. Credit amounts depend on the eligible plans, and an additional line on an existing account does not qualify as the friend's new account.

Family-plan savings apply when two or more eligible lines on Unlimited+ and/or Unlimited Premium are active on the same account. Boost Mobile states that these savings are applied at the account level and at checkout when the eligibility requirements are met; they end if the account no longer meets those requirements.

Referral credit affects a service bill, whereas family-plan savings are linked to how the account's eligible lines are set up. Different plans can share an account, as explained in the FAQ on mixing plans, but the family-plan discount has its own eligible-plan conditions.

Student offers, BYOD and deal updates

Bring Your Own Device lets customers activate many popular unlocked phones that are compatible with Boost Mobile. Keeping a compatible phone is a different route from buying a discounted replacement: the purchase is for service rather than a new handset. Boost Mobile provides a compatibility check before activation.

The student offer includes students and graduates; Boost Mobile says an active school email is needed to start eligibility verification. The offer has an introductory service price for a defined promotional period.

Boost Mobile lets account holders manage promotional communications on the web or in its app. These updates cover deals, discounted devices, special offers and product launches.

Discounted first months on Unlimited and in-store deals for switchers: Boost Mobile's Black Friday and Cyber Monday, 2023 to 2025

On Cyber Monday, November 27, 2023, an online-only exclusive for new customers took half off the first month on all of Boost Mobile's Unlimited plans, with AutoPay required; on the $25 Unlimited plan, the price after that first month was $25 a month plus taxes and fees. Boost Mobile's 2024 Black Friday offers began on November 19, 2024, and its Cyber Monday offers followed at midnight on December 2, 2024. That 2024 sale took half off the first month of the Unlimited plan, bringing it to $12.50, after which the plan cost $25 a month, with AutoPay required. By November 17, 2025, early Black Friday deals were online, and the featured Black Friday offer of 2025 gave new customers who brought their own phone the Unlimited plan at $10 a month for the first three months, on up to three lines per online order, then $25 a month, again with AutoPay required. Boost Mobile's 2025 Cyber Monday deals were set to go live at midnight on November 30, 2025, and to run for two days.

On Cyber Monday 2023, several phone prices came with half off the first month of the $40 plan. In 2024, every online Black Friday phone deal came with a named plan, such as Unlimited+, Unlimited Premium or an Infinite Access plan. Buying an eligible 5G phone during the 2024 sale also earned a free year of service, paid as $25 monthly credits for 12 months on up to five lines of select plans, the $25 Unlimited plan among them, with taxes extra. In 2025, the phone deals that Boost Mobile headlined online required the $60 Unlimited Premium plan or the $50 Unlimited+ plan, the free-phone offers could not be combined with other offers, and the holiday device deals did not require a trade-in. All three editions, in 2023, 2024 and 2025, also had in-store-only deals alongside the online ones, including deals for shoppers switching to Boost Mobile with ID verification, and in 2025 the in-store phone deals that Boost Mobile headlined paired a number transfer with the required plan.

Boost Mobile savings in fall 2026

Updated for fall 2026. Fall phone shopping at Boost Mobile brings together device purchases and the service attached to them. The recurring offer structures include selected phones paired with qualifying plans, number-transfer offers, service prepayment and participating-store trade-ins. A launch or switching promotion can use one of those structures.

In late October 2026, Boost Mobile paired free and discounted phones with Unlimited+ or Unlimited Premium on its deals page, in several cases together with a number transfer, and offered new customers bringing their own phone a reduced introductory price on the Unlimited plan. For a new phone, the way to save depends on the eligible purchase and plan. If you already own a compatible phone, BYOD focuses on service. Referral credits and eligible family-plan savings affect the account, rather than the sticker price of a replacement phone.

Phone shopping on the 2026 holiday calendar: Black Friday 2026 and Cyber Monday 2026 arrive in the final days of November, and the season then runs through the December holidays into January 2027.
