Boost Mobile vs Tello: Which Is Cheaper, Faster & Better Value?

Boost Mobile and Tello both sell unlimited phone plans for $25, but these plans are nowhere near identical.

Tello gives you more high-speed data, includes hotspot use and lets unused Unlimited data roll over. Boost gives you a broader AT&T-led network, physical stores and much better phone discounts.

For somebody bringing an unlocked phone and looking for the most data at the lowest price, Tello is the better deal.

Boost makes more sense if AT&T coverage is stronger where you live, you want to buy a heavily discounted phone, or you prefer having a store you can visit.

Boost Mobile vs Tello: Quick Comparison

Which Is Cheaper?

Tello is the cheapest provider overall because it sells smaller plans for people who do not need unlimited data.

• Boost’s main plans begin at $25.
• Tello lets you choose between 2GB, 10GB, 20GB and Unlimited data.

Tello’s current plans

Taxes and regulatory charges are added according to your billing address. Tello’s Broadband Facts label lists a cost recovery charge of up to $0.30.

Every Tello data plan includes hotspot access. On the fixed-data plans, hotspot usage comes from the normal data allowance. Unlimited includes a separate 10GB hotspot allowance.

Tello also lets you build a custom plan with fewer minutes, no data or no calls. That can be useful for a backup phone, child’s device, basic phone or emergency line.

Boost Mobile’s current plans

Taxes and fees are added. Each listed price includes a $5 AutoPay discount.

Turn off AutoPay and Boost’s prices become:

• Unlimited: $30
• Global Connection: $45
• Unlimited+: $55
• Unlimited Premium: $65

Boost is currently giving eligible new customers its Unlimited plan for $10 per month during the first three months, followed by $25 per month with AutoPay.

That makes Boost cheaper during the opening three months, but Tello supplies more data and hotspot use once the promotional period ends.

The $25 Plan Comparison Is Not Close

This is the comparison that matters most because both carriers advertise unlimited service for $25.

Tello gives you 20GB more high-speed data, 10GB of hotspot use and included international calls for the same base price.

That is a fairly brutal win.

Boost’s $25 plan should only be chosen over Tello Unlimited if:

• AT&T has better local coverage
• You want the current three-month introductory discount
• You need access to Boost stores
• You are buying a discounted phone through Boost
• T-Mobile performs badly where you live

For almost every other $25-plan buyer, Tello provides more for the money.

Tello’s 30-Day Billing Is Easy to Miss

Tello calls its service monthly, but each plan lasts 30 days.

That is slightly different from paying on the same date every calendar month.

A year contains 365 days, so a 30-day renewal schedule produces roughly 12.17 billing periods per year.

At $25 every 30 days, the annualized base cost is approximately:

$25 × 365 ÷ 30 = $304.17

Boost’s normal $25 monthly plan comes to $300 across 12 calendar payments, before taxes and fees.

This does not make Boost the better deal. Tello still supplies 20GB more high-speed data and includes hotspot use.

But it does mean Tello’s real yearly base cost is closer to $304 than $300.

Your Tello renewal date also gradually moves earlier. Buy the plan on July 5 and Tello says it will normally renew on August 4, not August 5.

It is not a deal-breaker, but it is something most comparisons ignore.

Which Offers the Best Value?

Tello Unlimited Now Has Data Rollover

Tello has added a useful feature to its Unlimited plan.

Customers can roll over up to 50GB of unused high-speed data each month. The total high-speed balance can reach a maximum of 100GB.

For example, imagine you use only 20GB from your 50GB allowance.

You could carry the remaining 30GB into the next cycle, giving you 80GB of high-speed data.

Tello’s conditions state that you must:

• Remain on an Unlimited plan
• Keep the account in good standing
• Avoid cancelling or suspending the line

Changing to another plan removes the Unlimited rollover balance.

This makes Tello far better for people whose data use changes from month to month. You may use 15GB during a quiet month and 70GB while traveling. The unused allowance gives you room for the busier period.

The rollover does not increase the included 10GB hotspot allowance.

Which Has Better Coverage?

Boost Mobile wins for overall coverage.

This is where the comparison becomes more complicated than “Boost uses one network and Tello uses another.”

Boost Mobile’s network in 2026

Boost now operates as what EchoStar calls a hybrid mobile network operator.

Following EchoStar’s 2025 spectrum agreement, AT&T became Boost’s primary network partner. Boost customers connect through Boost’s cloud-based core and AT&T’s cell sites, with continued access to T-Mobile’s network.

EchoStar says parts of Boost’s old radio network are being decommissioned over time. EchoStar’s network announcement describes the current system as Boost’s core combined with AT&T’s nationwide network.

In plain English:

• Boost manages your account, service and network core.
• AT&T provides the primary towers.
• T-Mobile access continues under the agreement.
• Boost is no longer a normal single-network MVNO.

That gives Boost a coverage advantage over Tello, particularly in locations where AT&T reaches farther than T-Mobile.

Tello’s network

Tello uses T-Mobile’s 5G and LTE network.

T-Mobile has built excellent 5G coverage across cities and suburbs, but AT&T can be stronger in rural areas, along highways and in some buildings.

The likely coverage winners are:

• Cities and suburbs: Depends on the local tower
• Average 5G availability: Tello and T-Mobile are often stronger
• Rural areas and long road trips: Boost has the safer setup
• Weak T-Mobile locations: Boost
• Weak AT&T locations: Tello may work better

Coverage is intensely local.

A national coverage percentage cannot tell you whether the supermarket near your home is a dead zone. Test the service at home, work and along your normal commute before transferring your number.

Which Has Faster Data?

Tello has the stronger speed potential, but neither carrier guarantees it will be faster at your address.

Tello benefits from T-Mobile’s large mid-band 5G network. Independent national testing has regularly placed T-Mobile ahead of AT&T for average 5G download speed and 5G availability.

That makes Tello a strong choice in towns and cities with T-Mobile Ultra Capacity coverage.

Boost now relies primarily on AT&T’s network. AT&T’s average speeds can be lower, but the network has broad coverage and may produce a more stable connection in areas where T-Mobile is weak.

There are three reasons not to make this decision from national speed-test averages alone.

1. Your local tower matters more

A nearby AT&T tower will beat a distant or overloaded T-Mobile site.

The reverse is also true.

2. Network priority is not fully transparent

Neither carrier makes its exact priority position wonderfully clear on the main plan page.

A fast underlying network can still slow if your traffic receives lower priority during congestion.

3. Your phone affects speed

A recent US-market iPhone, Pixel or Galaxy is more likely to support:

• T-Mobile’s important 5G bands
• AT&T’s 5G+ bands
• Modern carrier aggregation
• Better MIMO
• Newer modem technology

An older or imported phone can produce very different results on the same plan.

Our speed verdict: Tello is more likely to win in a strong T-Mobile 5G area. Boost may be faster or more consistent anywhere AT&T has the better local network.

What Happens After You Use the High-Speed Allowance?

This matters because both carriers use the word “unlimited.”

Boost Mobile

Boost says customers exceeding the premium-data allowance may have speeds reduced to 512kbps.

The thresholds are:

• Unlimited: 30GB
• Global Connection: 40GB
• Unlimited+: 40GB
• Unlimited Premium: 50GB

512kbps is enough for:

• Messaging
• Email
• Basic web pages
• Audio streaming at modest quality
• Slow navigation updates

It is poor for:

• HD video
• Large app downloads
• Cloud backups
• Video calls
• Hotspot use
• Uploading photos and video

Tello

Tello Unlimited includes 50GB of high-speed data. After that, data continues at reduced speeds for the remainder of the 30-day billing period.

Tello’s Broadband Facts label does not provide one simple post-threshold speed on the main plan table.

The extra 20GB before reduction gives Tello an obvious advantage for heavier users.

Tello’s rollover can also raise the amount of high-speed data available during a later month, provided you have unused data from previous Unlimited cycles.

Which Is Better for Hotspot Use?

Tello wins easily at $25.

Tello Unlimited includes 10GB of hotspot data. Its 2GB, 10GB and 20GB plans let you use the entire data allowance for hotspot access if needed.

Boost’s $25 Unlimited plan does not include hotspot use as standard.

You need to:

• Buy a hotspot add-on
• Choose Unlimited+
• Choose Unlimited Premium

Boost says hotspot usage on its higher plans comes from the plan’s monthly high-speed data package rather than sitting in a separate unlimited bucket.

This makes Boost Unlimited+ a difficult value proposition next to Tello.

Boost Unlimited+ costs $50 with AutoPay and includes 40GB of premium data plus hotspot access. Tello charges $25 for 50GB of high-speed phone data and 10GB of hotspot.

Boost is asking twice as much while supplying less high-speed data. Its advantages are its broader network setup, phone discounts, stores and international calling package.

If hotspot is the main priority, you should also consider Visible. Its plans include unlimited hotspot use with fixed speed caps.

See our current Visible recommendation.

Which Is Better for Light Data Users?

Tello wins by a mile.

Boost pushes customers toward unlimited service starting at $25.

Tello lets light users pay:

• $10 for 2GB
• $15 for 10GB
• $20 for 20GB

If you spend most of your time on home and office Wi-Fi, 10GB may be plenty.

Choosing Tello’s $15 plan instead of Boost Unlimited saves approximately $10 per billing period while still including unlimited calls, texts and hotspot access from the 10GB data allowance.

The $10 Tello plan is also a good match for:

• A child’s first phone
• A backup handset
• An elderly relative
• A basic phone
• A car emergency phone
• Somebody who mostly calls and texts
• A second line used for work

Boost cannot match that flexibility with its current mainstream plan lineup.

Which Is Better for Families?

This one is mixed.

Boost has actual multi-line discounts

Boost advertises discounts when two or three lines are added to Unlimited+ or Unlimited Premium.

It also lets families purchase discounted devices and use retail stores for activation help.

That can make Boost more convenient when setting up several new phones at once.

Tello lets each person choose a different plan

Tello family accounts can contain up to 10 lines.

Each line has its own:

• Data allowance
• Minutes
• Renewal
• Payment method
• Plan selection

That is useful when family members have very different needs.

For example:

The total base cost would be $70 per 30-day cycle before taxes.

Four Boost Unlimited lines would be easier to understand as identical plans, but everyone would be paying for at least 30GB whether they need it or not.

Tello does not provide a conventional multi-line service discount. Its savings come from letting each person buy only the data they need.

Our family verdict:

• Choose Boost if you want stores, device deals and conventional multi-line discounts.
• Choose Tello if every family member uses a different amount of data.

Which Is Better for International Calling?

Tello is better on its cheaper plans.

Every Tello phone plan with minutes includes calls to more than 60 countries. Tello says international calling is intended for normal person-to-person use and limits included international calls to 1,000 minutes per 30-day cycle.

That is included even with its lower-cost plans.

Boost’s $25 Unlimited plan does not include the same international package. You need an add-on or a higher plan.

Boost’s Global Connection and Unlimited+ plans include international calls and texts across a broad list of destinations.

If you regularly call friends or family abroad but rarely travel internationally, Tello is the cheaper route.

Which Is Better for International Roaming?

Boost has the more conventional bundled roaming option, but Tello can be cheaper for occasional travel.

Boost roaming

Boost’s $40 Global Connection plan includes:

• Global calling and texting
• 1GB of international roaming data
• 40GB of domestic premium data

Unlimited Premium includes North America Connect, which provides:

• Calls and texts between the US, Canada and Mexico
• Calls and texts while roaming in Canada and Mexico
• 5GB of roaming data in Canada and Mexico

North America Connect can also be added to other eligible plans for $10 per month.

Tello roaming

Tello supports roaming in more than 200 countries and territories through Pay As You Go credit.

Example rates shown by Tello can start around:

• $0.05 per minute
• $0.01 per text
• $0.01 per MB

Actual prices vary by destination.

Tello is temporarily providing free roaming across selected European countries until September 30, 2026. During the promotion, usage is deducted from the customer’s normal plan allowance.

This is temporary. From October 1, European roaming is scheduled to return to Pay As You Go billing unless Tello extends or replaces the promotion.

Tello international roaming must be enabled in the customer account. The line must also be activated and used in the US before roaming abroad.

Our roaming verdict:

• Choose Boost for regular Canada and Mexico travel.
• Choose Boost Global Connection if you want included international data without topping up credit.
• Choose Tello for occasional trips and low PAYG usage.
• Do not choose Tello solely for free European roaming because the current promotion is about to end.

Which Is Easier to Manage Long Term?

Tello is easier for somebody bringing an unlocked phone.

Tello lets you:

• Upgrade or downgrade online
• Build a custom plan
• Cancel through your dashboard
• Retrieve port-out information online
• Add data through the account or text
• Use eSIM
• Keep different plans under one family account
• Contact support around the clock

There is no requirement to call an agent just to cancel.

Boost requires customers to cancel by calling support or visiting a Boost store. Its standard customer care operates every day from 8am to midnight Eastern Time.

Boost’s $25 price also depends on AutoPay. If AutoPay is removed, the bill rises to $30.

Tello AutoPay renews the selected plan, but its advertised price is not based on a $5 AutoPay discount.

The main inconvenience with Tello is the 30-day billing cycle. Renewal dates move, and you end up with slightly more than 12 charges over a full 365-day period.

Long-term hassle winner: Tello

Which Has Better Customer Support?

Boost gives you more ways to get help.

Boost provides:

• Physical stores
• Telephone support
• Online chat
• Dedicated activation support
• International support

Normal Boost support is available daily from 8am to midnight Eastern Time.

Tello does not have retail stores, but it supplies:

• 24/7 phone support
• Online account management
• Email support
• Help documentation
• Self-service cancellation
• Self-service port-out details

Boost is better for somebody who wants a shop they can physically visit.

Tello is better for somebody who wants to manage everything online without dealing with a sales rep.

Which Has Better Phone Deals?

Boost wins comfortably.

Boost sells heavily discounted Motorola, Samsung, Apple and Boost-branded phones. Discounts can run into hundreds of dollars when a device is purchased alongside an eligible plan.

Tello sells phones but is far more focused on bringing your own unlocked device. Its service pricing is the attraction, not subsidized hardware.

There is a catch with Boost’s cheap prepaid phones.

Boost’s current unlocking policy says an eligible prepaid device is unlocked one year after initial activation, provided:

• Any device balance is paid
• The account meets usage and payment conditions
• The account is active and in good standing
• The phone is not flagged for fraud, loss or theft

That means a $20 or free Boost phone may be tied to Boost for a year.

Do not buy a discounted Boost device if you expect to switch again after a few months.

If you already own a good unlocked phone, Tello is cleaner. If you need a new phone and plan to remain with Boost for at least a year, Boost’s discounts can save you a fair amount upfront.

You can also compare unlocked refurbished devices through the KnowYourMobile Phone Finder. Buying unlocked avoids tying the phone and service together.

Our refurbished smartphone guide explains what to check before buying.

Which Has Better eSIM and Device Support?

Both support eSIM, but compatibility must be checked before ordering.

Boost’s current eSIM list includes selected:

• US iPhones from the iPhone 12 onward
• Samsung Galaxy S and Z models
• Google Pixel phones
• Motorola phones
• Selected tablets and cheaper Android devices

Tello supports eSIM on compatible unlocked devices and runs on T-Mobile.

Most recent US versions of the iPhone, Pixel and Galaxy families should work, but imported Android phones can be more troublesome.

An unlocked phone is not automatically compatible. It must also support the network bands and carrier features required by the provider.

Run the device’s IMEI through the carrier checker before paying.

Do Boost and Tello Support Apple Watch?

Neither provider currently makes cellular smartwatch support a central part of its mainstream phone-plan lineup.

If you need a cellular Apple Watch, Pixel Watch or Galaxy Watch plan, Visible is the stronger low-cost option.

Visible sells smartwatch service as an add-on, while Visible+ Pro includes a compatible watch line in the monthly price.

Compare Visible’s current plans.

The Downsides of Boost Mobile

Boost’s main drawbacks are:

• Only 30GB of high-speed data on the $25 plan
• No included hotspot on the base plan
• $25 price requires AutoPay
• Taxes and fees are extra
• Speeds may fall to 512kbps after the allowance
• Cancellation requires a call or store visit
• Prepaid phones can remain locked for one year
• Network arrangements have changed repeatedly
• The $50 and $60 plans are difficult to justify without using the included extras or phone discounts

The network transition deserves attention.

Boost spent years building its own 5G radio network before EchoStar changed direction and made AT&T the primary network partner. The current hybrid setup can provide good coverage, but it makes old Boost coverage reviews and network guides unreliable.

Check the date on anything you read about Boost’s network.

The Downsides of Tello

Tello’s main drawbacks are:

• T-Mobile is the only domestic network
• Rural coverage can be weaker than Boost’s AT&T-led service
• Video is generally optimized to 480p
• Unlimited data slows after the high-speed balance is used
• Unlimited hotspot stops after 10GB
• Taxes and surcharges are added
• No physical stores
• No large phone subsidies
• Family lines do not receive a standard group discount
• Plans renew every 30 days, not every calendar month
• International roaming outside promotions relies on PAYG credit

Tello’s fixed-data plans also stop supplying data when the allowance is exhausted unless you buy more, renew early or have PAYG data available.

Boost Mobile vs Tello: Final Verdict

Tello is the better carrier for most people comparing these two.

At $25, Tello gives you 50GB of high-speed data, 10GB of hotspot, international calling and data rollover.

Boost gives you 30GB, no included hotspot and requires AutoPay to maintain the $25 price.

Tello is also much better for light users. Its $10, $15 and $20 plans prevent you from paying for data you do not need.

Boost wins in three areas:

• Overall coverage
• Physical support
• Discounted phones

Those are not small wins. If T-Mobile reception is poor at your home, none of Tello’s extra data matters. Boost is also the obvious choice if its phone discount saves you hundreds of dollars and you are happy to stay for the unlocking period.

But with equal local coverage and an unlocked phone already in your hand, Tello is the easy recommendation.
