How to Give Your Kid a Cellphone Without Breaking the Bank (November 2026)

Before You Buy Anything: Is Your Kid Ready for a Phone?

There’s no license test for this, and no magic birthday either. The American Academy of Pediatrics’ Q&A on getting your first phone says the teens it heard from agreed there’s no single perfect age, and it notes that most kids get their first smartphone around age 11. What the AAP points to instead is readiness: a kid who shows they can be responsible in other parts of life, like school and chores, and parents who are ready to help with the phone side of things.

So, the honest version of the question is less “how old?” and more “what for, and can they handle it?” A few things we’d ask ourselves first:

• Do they need to reach you when you can’t reach them? The walk home from school, practice that runs late, a weekend at the other parent’s place. That’s the strongest case for a phone, and it doesn’t need much data.
• Do they keep track of their stuff? Count the water bottles and hoodies lost this year. Be honest.
• Will they follow a rule they don’t love? Say, the phone sleeps in the kitchen. If that one’s a fight, everything else will be.
• Are you ready to check in on it? A phone handed over and never looked at again is the expensive kind, in every sense.

And it isn’t all or nothing. A first phone can be a calls-only line in a hand-me-down, or a smartphone with most of its features switched off. You can always loosen things later. Tightening them after the fact is a lot harder (ask any parent who’s tried to take back a social media app).

Step 1: Find the Phone (Check the Junk Drawer First)

Your kid’s first phone doesn’t need to be new, shiny or expensive. It needs to turn on, hold a charge and survive a backpack. The old phone in your junk drawer, the one you kept “just in case”, is usually the cheapest phone you’ll ever find. Think of it like the hand-me-down car you got at 16: not glamorous, perfectly fine.

Make sure it’s unlocked

A locked phone only works with the carrier that sold it. The FCC’s guide to cell phone unlocking says that unless a phone was specifically sold as unlocked, it’s probably locked, and that a provider may not unlock it until you’ve paid off any balance or met the terms of a contract. Unlocking policies vary by provider, so the carrier that sold the phone is the one to ask.

On an iPhone you can check in about ten seconds. Apple’s unlocking guide says to open Settings, tap General, then About, and look at Carrier Lock: “No SIM restrictions” means it’s unlocked. If it isn’t, Apple is clear that only your carrier can unlock it. On Android the menu path depends on who made the phone, which is one more reason to just ask the carrier.

Make sure it works on the network you’ll use

Unlocked isn’t quite the same as compatible. The FCC points out that unlocking a phone designed for one network may not make it work on another provider’s network. If the phone is old, be extra careful here. Confirm it works before you buy a plan for it, and use US Mobile’s network coverage page to check the places your kid actually spends time.

Wipe it and toughen it up

Sign the phone out of your accounts and erase it before it changes hands, so your kid starts clean and your photos stay yours. Then spend a little on a case and a screen protector. Kids drop things. All of them. Every price in the rest of this guide is for service only, so a cracked screen comes out of a different budget.

Step 2: Pick the Cheapest Line That Fits

The easiest mistake to make is buying a kid the same plan the grown-ups have. Size the line to what your kid will actually do with it. A nine-year-old who needs to call home after soccer and a sixteen-year-old who watches videos on the bus are two very different lines.

For calls home and the odd text

If you’re on US Mobile Light yourself, a second Light line is the easy win: it adds $8/mo, gets unlimited talk and text, and shares the account’s 2GB, so two lines come to $18/mo total with taxes and fees included. If your kid runs the shared data dry, extra data is $2 per GB. Fair warning, though: shared means shared, and one kid’s video habit can eat your 2GB too.

Want even less? US Mobile’s build-your-own plans sell unlimited minutes on their own for $8/mo, or unlimited texts on their own for $6/mo, with no data at all. Buy both and the prices simply add up, which is why Light, at $10/mo for unlimited talk and text plus 2GB, usually makes more sense if you want both. There’s more on mixing and matching in our guide to how to build a cheap cell phone plan.

For a kid with a bit more screen time

Light on its own line is $10/mo for one line with 2GB, unlimited talk and text and hotspot included, or $96/yr ($8/mo) if you pay for the year up front. With several kids, By the Gig gives everyone a bigger shared pot: on By the Gig 10GB, two lines are $28/mo total and three lines are $36/mo total, each extra line adding $8, taxes and fees included.

For a teen who streams

Stop counting gigabytes and go unlimited. Unlimited Starter is $25/mo, or $270/yr ($22.50/mo) on the yearly plan, with 20GB of hotspot and unlimited high-speed data on one of its networks (speeds may slow after 70GB a month on the others). New lines can get the first year of yearly Starter for $199, and it then renews at $270/yr. Unlimited Flex is yearly only, at $210/yr ($17.50/mo), with 5GB of hotspot, but speeds may slow after 10GB a month. US Mobile’s Unlimited plans don’t have a multi-line discount, so a kid’s Starter line costs $25/mo whether it’s your second line or your fifth.

“First 12 months” on a monthly price is that price times 12. The yearly Starter offer is for new lines: $199 for the first year only, then it renews at the regular $270/yr. Speeds on Starter may slow after 70GB a month on some networks.

One quirk worth spotting: in year one, a brand-new yearly Starter line ($199) costs less than Flex ($210), with 20GB of hotspot instead of 5GB and no slowdown at 10GB. From year two it’s $270 against $210, so Flex wins on price if your teen’s usage stays modest.

Prefer to spend nothing at all? TextNow Free is $0/mo, paid for by ads, with unlimited talk and text and 550MB of data, plus a $3.99 SIM and whatever taxes apply where you live. That’s thin, but for a phone that mostly calls home it can do the job. For every carrier side by side, including free and Big 3 options, see our phone plans for kids comparison, and for a tight budget, the $10 mobile phone plans roundup.

Already on a Big 3 family plan? Check there first

If both parents are already on a Big 3 family plan, run the numbers there before you go anywhere. Those plans get cheaper per line as you add people, so a kid’s line can add surprisingly little to the plan price. These are each carrier’s stated totals with AutoPay, before taxes and fees:

• T-Mobile Essentials 2.0: $90/mo for 2 lines and also $90/mo for 3, because “3rd line free” bill credits cover the third line. Cancel any line and the credits stop. On top: a $5.49-a-line fee, government surcharges T-Mobile puts at $0.08 to $4.57 a line, taxes, and a one-time $35-a-line device connection charge.
• Verizon Unlimited Welcome: $110/mo for 2 lines and $120/mo for 3, so the kid’s line adds $10 to the plan price. On top: a $40 activation fee per line, a $3.78-a-line administrative charge that rises to $4.69 on November 15, 2026, and surcharges Verizon says can add 16% to 58% to your monthly charges.
• AT&T Value 2.0: $90/mo for 2 lines and $105/mo for 3, so the third line adds $15, and only 5GB of its data is full speed. On top: $35 to activate and a fee of up to $4.99 a line. AutoPay is $10 off with a bank account but only $5 with a debit card.

Each of those is an unlimited-data line, so the fair comparison on our side is Unlimited Starter at $25/mo with taxes and fees included. On the plan price alone, adding a third line on the Big 3 can come out cheaper. What the sticker leaves out is the fees and taxes on every line, plus the activation charges. And pulling only the kid off a Big 3 plan rarely saves much, since the remaining lines get pricier per line. The full bill math, carrier by carrier, is in our family phone plans table.

Step 3: Set Up the Line

This is the quick part. Honestly, finding the charger for the old phone may take longer.

1. Decide: new number or a transferred one. Most first phones get a brand-new number, and there’s nothing to move. If your teen already has a number with another carrier, transferring it in qualifies for US Mobile’s current port-in deal: Unlimited Starter is $15/mo for the first 6 months with autopay, then it goes back to the regular $25/mo (limit 5 per household). Our switching carriers guide covers what to have ready.
2. Pick the plan and the network. Every US Mobile line gets access to all three major US wireless networks, branded as Warp 5G, Dark Star, and Light Speed. Choose the one that’s strongest at home and at school when you sign up, and if it disappoints, you can move the line to a different network later from your dashboard. The Multi-Network add-on, $10/mo per line ($7.50/mo on annual), puts more than one network on the same phone, though for a kid’s first line it’s usually more than you need.
3. Activate it and test it. Make a call, send a text and, on a plan with data, load a map with Wi-Fi switched off. Better to find a problem at the kitchen table than at the bus stop. US Mobile lists 24/7 phone support if something snags.
4. Watch the free-trial renewal. If you’re also bringing your own number over, new customers who transfer one number get a 30-day free trial with 30GB on select networks. After that, the line renews on monthly Unlimited Premium ($44/mo) unless you change plans, so put a reminder in your calendar.
5. Save the important numbers. Yours, the other parent’s, a grandparent, a neighbor. Mark them as favorites so they’re one tap away when it matters.

Step 4: Turn On Parental Controls (There Are Two Layers)

Parental controls live in two places: the plan and the phone. Most of the useful stuff is on the phone, and it’s the same whichever carrier you pick.

The plan layer

US Mobile lists parental controls in its app on Light, Unlimited Starter and Unlimited Premium. For By the Gig, Flex and the build-your-own plans, US Mobile doesn’t say, so lean on the phone’s own controls there. If you’d rather stay with a Big 3 carrier, T-Mobile lists FamilyMode with Essentials 2.0; for the rest, see the parental-controls rundown in our phone plans for kids guide.

A small plan is a control of its own, by the way. A calls-only line has no data to misuse, and a shared 2GB runs out long before a kid can binge a season of anything.

On an iPhone: Screen Time

Apple’s guide to setting up parental controls on your child’s iPhone runs through Family Sharing. You need Family Sharing set up first, your kid needs their own Apple Account in the family group, and you manage the settings as the organizer or a parent or guardian in it. From there, Apple lists:

• Allowed Contacts: choose who your child can communicate with in Messages, FaceTime and Phone. This is the setting behind “a phone that only calls Mom and Dad”.
• Screen Time Schedules and Time Allowances: which apps are available at different times of day, and daily time limits by app category.
• Ask to Buy and Ask to Browse: your kid asks before an eligible download or purchase, or before visiting a new website, and you approve or decline.
• Content & Privacy Restrictions and Communication Safety: age-based content limits, plus warnings or blocking for photos and videos with detected nudity in messages and FaceTime.

On Android: Google Family Link

Google Family Link works on certain Android and Chrome devices. Google says it lets you set screen time limits, downtime and school-time schedules; set time limits per app or block apps; require approval for new apps; and manage controls on Chrome, Play, YouTube and Search. It can also show your kid’s location on a map when the device is on, recently active and connected to the internet, ring the device and check its battery. Family Link has its own section for contacts, calls and texts too; Google’s overview doesn’t spell out exactly what it restricts, so look at it on your kid’s phone.

Step 5: Agree on the Rules Before It’s Theirs

The controls do the enforcing. The rules do the teaching. And they’re much easier to set while the phone is still in your hand.

The AAP’s first-phone guidance suggests making a Family Media Plan together, starting the phone off with a smaller number of functions (talk, text, video chat, maps, camera), and remembering that getting a phone doesn’t have to mean getting social media: start with texting. It also suggests downtime, like switching off Wi-Fi before bed.

Our own short list, for what it’s worth:

• Write the rules down, and pick a date to revisit them. Three months is about right.
• The phone charges overnight somewhere that isn’t the bedroom.
• You know the passcode. Non-negotiable, at least at first.
• New apps and new contacts get a conversation, not just a tap.
• Tell them what happens if it’s lost or broken before it is.

Then hand it over, and yes, pat yourself on the back. You’ve done the thinking most people skip.

Which Setup Is Right for Your Kid?

• A young kid who just needs to call home: a hand-me-down phone with Allowed Contacts on, and a US Mobile minutes-only line at $8/mo, or a second Light line at $8/mo if you’re on Light yourself.
• A tween who texts and uses maps: Light, at $10/mo on its own line or $96/yr ($8/mo), taxes and fees included.
• Two or three kids on small plans: By the Gig 10GB, $28/mo for 2 lines or $36/mo for 3, everyone sharing the 10GB.
• A teen who streams on cellular: Unlimited Starter, $25/mo, or $199 for a new line’s first year on the yearly plan, then $270/yr.
• Parents already on a Big 3 family plan: price the third line there first, then add the fees before you compare.

How We Put This Guide Together

US Mobile wrote this guide and sells some of the plans in it. To keep that honest, every price and allowance here was read on the carrier’s own plan page or its FCC Broadband Facts label on November 3, 2026, and we saved screenshots of those pages. Prices are for one line without AutoPay unless we say otherwise. Multi-line prices are the totals each carrier states, except US Mobile’s Unlimited plans, which cost the same for every line. “First 12 months” on a monthly plan is the monthly price times 12, and “/mo” on a yearly plan is the yearly price divided by 12. Where a carrier doesn’t publish something, we say “Carrier does not say” rather than guess.

On parental controls, we credit a carrier only with what it lists alongside the plan; we don’t test or rate the controls. The phone-level steps come from Apple’s and Google’s own support pages, the unlocking advice from the FCC and Apple, and the readiness and house-rules guidance from the American Academy of Pediatrics, each linked where we use it. The readiness checklist and house rules marked as ours are our editorial suggestions, not medical advice.

We don’t rate network speed or coverage ourselves. For customer ratings, see Consumer Reports; Consumer Reports does not endorse products or services. For speed and coverage, independent sources include Ookla’s Speedtest reports and Opensignal, and the FCC’s wireless consumer guides explain your rights as a customer.
