Data-Only Lines for Scanners, Tablets and Point-of-Sale Devices (2026)

Verdict: Data-only lines make sense for scanners, tablets and point-of-sale devices when the device needs a mobile data connection but no voice line, and the right choice is usually the smallest data allowance that still covers the device’s real daily work, quoted for that exact device type. A scanner that sends small inventory updates, a tablet that runs a sales app all day, and a card reader that must process payments without delay do not have the same data needs, even though all three can run on a data-only line. Treating them as one kind of line leads to the two classic mistakes: paying for a large allowance a scanner never uses, or starving a tablet that is expected to stream video and sync large files.

This guide explains data-only lines for business devices in plain terms: what a data-only line is, how the published DataConnect data-only plans for tablets, laptops and wearables are structured, how to think about scanners and point-of-sale devices where no device-specific price is published in this guide, and how to manage a fleet of device lines without losing track of costs, security or support. It also explains how data-only lines differ from ordinary business wireless phone lines, so you can decide which kind of line each device and each person actually needs.

Data-Only Lines for Business Devices Explained

A data-only line is a mobile line that provides a data connection for a device, without a voice line attached. That distinction matters more than it first sounds. A phone line is built around a person who talks, texts and uses data, and its plan is priced and managed with that person in mind. A data-only line is built around a device that sends and receives data as part of a job: a scanner confirming stock, a tablet showing a customer record, a point-of-sale terminal authorising a payment, or a laptop working away from the office network. The device does not need to make calls, so you should not pay for a voice service it will never use, and you should not manage it as if it were an employee’s phone.

The practical benefit is separation. When device lines sit on their own lines, separate from staff phone lines, the business can see exactly what its devices cost, how much data they use, and which devices are active. That separation also makes support simpler. If a tablet stops syncing, the problem is a device data problem, not a tangle of personal and business usage on one line. If a scanner is retired, its line can be reviewed on its own, rather than being buried inside a phone plan. Separation does not automatically save money — a poorly sized data-only line can cost as much as a badly chosen phone line — but it does make the cost visible, and visibility is the first step to controlling it.

Which Business Devices Need a Data Only Plan

Tablets are the most common business device on a data-only line, because they are used in so many roles: a sales tablet in a showroom, a tablet on a delivery route, a tablet at a trade counter, or a tablet used for forms and signatures on site. A tablet’s data use depends heavily on its job. A tablet that mainly shows a catalogue or a booking system and syncs text records will use far less data than a tablet that streams training video, uploads photos all day, or runs a video call. Before choosing a plan, look at what the tablet actually does hour by hour, not what its specification sheet says it could do. A week of real usage, where available, is worth more than any estimate.

Scanners, point-of-sale devices and similar specialist devices sit at the other end of the range in many businesses, but not always. A handheld scanner that sends short stock updates uses very little data per transaction, yet a scanner fleet in a busy warehouse sends thousands of those updates a day, and the total still matters. A point-of-sale device sends payment data that is small in size but critical in timing: a delayed payment authorisation is a customer waiting at a till, even if the data itself is tiny. For these devices, reliability and coverage matter at least as much as allowance size, and the business should confirm the data-only price for that device type on its quote, rather than assuming a tablet price applies to a scanner or a card reader.

DataConnect Business Data Only Plans and Prices

The published DataConnect 2.0 data-only plans, from the AT&T support page updated 29 October 2026, give a clear starting point for tablets, laptops and wearables. Tablet Premium is $30 per month, with 50GB of premium high-speed data and 20GB of hotspot per line; after 50GB, speeds may slow if the network is busy. Tablet Standard is $20 per month, with 15GB of premium data, after which speeds may slow if the network is busy. Laptop Premium is $40 per month, with 125GB of premium data, after which speeds are at a maximum of 3Mbps. Wearable Premium is $10 per month, with 50GB of premium data, after which speeds may slow if the network is busy. All of these plans include unlimited data within and between the United States, Mexico and Canada, and 5G and 5G+ access where available.

Read those figures as plan definitions, not as a promise that every device will fit neatly into one row. A tablet on Tablet Standard at $20 is a sensible starting point for light, text-based work, while a tablet that regularly streams video or uploads media may need Tablet Premium at $30. A laptop on Laptop Premium at $40 has a much larger allowance because laptop work consumes more data, and the 3Mbps maximum after 125GB is a real limit to plan around, not a detail to discover mid-month. A wearable on Wearable Premium at $10 is priced for a small connected device, and its 50GB premium allowance should be read alongside what the wearable actually does, not assumed to mean it can carry a tablet’s workload.

Two cautions apply to every figure in that table. First, these are the published DataConnect figures checked in October 2026, and the quote for your business is the figure that matters: confirm the data-only price for your exact device types, line count and billing conditions before ordering. Second, do not transfer a price from one device type to another. A scanner or a point-of-sale device is not a tablet, and a router is not a laptop. Where no DataConnect figure fits the device in front of you, write “confirm the data-only price for that device type on your quote” into your planning notes and ask for that figure explicitly, so the quote answers the question instead of leaving it to assumption.

Scanner Data Line Business Choices for Warehouses and Shops

Scanners are easy to underestimate, because each scan looks trivial. A single barcode scan sends a small amount of data, but a warehouse scanner may scan hundreds or thousands of items in a shift, and a retail scanner may be in constant use across a trading day. The total data use is therefore the product of two things: how much data each scan and sync uses, and how many scans happen in a day. A business that counts only the first of those two numbers will under-size its scanner lines, while a business that counts both will have a realistic total. If the scanner application also downloads product images, price files or large catalogues, that background data can dwarf the scan data itself, and it should be counted too.

Management is the third scanner question. A scanner fleet is rarely one device; it is ten, fifty or hundreds of devices, often shared between shifts. Shared devices need a different management approach from personal phones: a clear record of which scanner belongs to which line, a process for reporting a faulty or lost scanner, and a way to remove a device from service without leaving its line running and billed. For a general guide to keeping lines, bills and users under control, see our guide to managing AT&T business lines, bills and users. The scanner question is therefore not only “which plan?” but “who owns this fleet day to day, and how will they know when a line is no longer needed?”

POS Device Data Plan Choices for Checkout and Card Readers

Point-of-sale devices have one requirement that outweighs almost every other: payments must go through, promptly, every time. A card reader or till that cannot authorise a payment is not a slow device; it is a closed till. That means a point-of-sale data line should be judged first on reliability and coverage at the exact location where payments are taken, and only second on allowance size. A small allowance may be perfectly adequate for payment data alone, but it will not be adequate if the same device also downloads menus, updates software, syncs inventory or streams content. Separate those jobs in your planning, and size the line for the total, not just for payments.

Backup connectivity is worth planning for point-of-sale devices even when the main connection is reliable. A till that relies on a single connection — whether that connection is fixed internet or a mobile data line — has a single point of failure. Businesses that cannot afford a payment outage should ask, before ordering, how a data-only line would work alongside their existing connection, and what happens during an outage: does the device fail over automatically, does staff need to switch it manually, and how quickly can normal service resume? Our guide to connecting point-of-sale devices and printers to business Wi-Fi covers the practical side of getting these devices onto a network in the first place, and it is worth reading alongside any data-only plan decision.

Security for point-of-sale devices also needs a clear owner. Payment devices handle sensitive transaction data, so they should not share a casual, unmanaged connection with guest or general staff devices, and access to their settings should be limited to the people who need it. Keep payment devices on their own managed lines where possible, keep their software updated, and know who to contact if a device behaves unexpectedly. These are basic disciplines, not advanced security measures, but they are the disciplines that prevent a small device problem from becoming a payment or trust problem. Confirm the data-only price for that device type on your quote, and confirm the security and management arrangements at the same time, so neither is left to chance.

How to Size a Data Only Plan for a Business Tablet Fleet

Hotspot use is a common surprise in tablet fleets. A tablet that is itself on a data-only line may also be used to share its connection with another device, and that shared use counts against the plan’s hotspot allowance where one applies. Tablet Premium includes 20GB of hotspot per line, which is a useful allowance for occasional sharing, but it is not an unlimited tether for a laptop fleet. If tablets are routinely used as hotspots for laptops, the business should size for that combined use, or give the laptops their own data-only lines instead. Our guide to mobile hotspot use for field and remote staff explains how hotspot allowances work in practice and why they are often the first limit a mobile worker hits.

Finally, build a review point into the tablet plan. Data needs change: a new app, a new photo workflow, a new delivery route, or a seasonal peak can all move a tablet group from one allowance to another. A quarterly review of actual usage by group — not by individual tablet, which is too much detail for most businesses — is enough to catch a group that has outgrown its plan or a group paying for allowance it never uses. When the review shows a change is needed, confirm the revised quote for your exact line count and device types before changing plans, and keep a note of what changed and why, so the next review starts from evidence rather than memory. To check the quote for your tablet, scanner and point-of-sale lines, get a business wireless quote for your data-only devices.

Managing Business Data Only Lines, Security and Costs

Managing data-only lines well is mostly about records and routine. Keep a simple inventory: which device, which line, which plan, who uses it or where it is kept, and when it was last reviewed. That inventory does not need special software for a small fleet — a shared list, kept up to date, is enough — but it does need an owner. Without an owner, devices accumulate: a retired tablet keeps its line, a replaced scanner keeps its line, and the bill grows quietly month by month. A quarterly check of the inventory against the bill catches those lines in minutes, and it is the single most effective cost control for device lines.

Costs should be reviewed in the same routine as security. A data-only line bill is the sum of its individual lines, and the total only makes sense when each line can be matched to a device that is still in use. If a line’s usage is consistently far below its allowance, consider a smaller plan for that device group; if usage regularly exceeds the premium allowance and speeds slow when the network is busy, consider a larger plan or a different arrangement for that group. Do not assume that pooling or sharing allowances will solve a sizing problem unless the quote explicitly describes how pooling works for your device types and line count. Describe pooled versus individual considerations generically in your planning — who shares, what happens when one device uses more than its share, and how the bill reflects it — and get the answer on the quote, not from assumption.

Data Only Lines Business Devices Ordering Checklist

Before ordering, work through a short checklist for each device type. First, list the devices and their jobs, and group them by daily data use. Second, note the published DataConnect figure that fits each group, where one fits, and mark the groups where no published figure fits — for scanners, point-of-sale devices and routers, confirm the data-only price for that device type on your quote. Third, test coverage where the devices actually work, not just where the office sits. Fourth, decide who manages the fleet, who updates shared devices, and how a lost or retired device is removed from billing. Fifth, confirm the quote in writing: device types, line count, plan for each group, billing conditions, and any one-time costs.

It also helps to compare data-only lines with ordinary business wireless phone lines before ordering, so the business does not buy the wrong kind of line for a person or a device. Business wireless phone lines under Wireless 3.0 are priced at $30, $40 and $50 per line on a 5+ lines, AutoPay and paperless billing basis for Standard, Advanced and Premium, with hotspot allowances of 5GB, 100GB and 300GB respectively, and mix-and-match per line. Those are phone lines, with unlimited talk, text and data in and between the United States, Canada and Mexico, 5G and 5G+ access, and ActiveArmor included. A device that needs a voice line belongs on a phone line; a device that only needs data belongs on a data-only line, and the two should not be confused in the quote. For the phone-line side of that comparison, see our overview of AT&T Business Wireless plans and our comparison of unlimited versus pooled data for business wireless.

Finally, remember that a data-only line decision is rarely permanent. Device fleets change, apps change, and routes and roles change, so the plan that fits today may not fit in a year. That is a reason to keep the inventory and the quarterly review, not a reason to delay ordering a line a device needs now. Order for the work the device does today, with a review date in the diary, and the business will have both working devices and a bill it can explain. A well-chosen data-only line is unremarkable in the best sense: the device connects, the work gets done, and nobody has to think about the line until the next review.

Data Only Business Devices Frequently Asked Questions

What is a data only plan for business tablet devices?

A data-only plan gives a tablet a mobile data connection without a voice line attached. The tablet can use apps, sync records, browse and stream within its data allowance, but it is not a phone line. Tablet Standard at $20 and Tablet Premium at $30 are the published DataConnect tablet options, with 15GB and 50GB of premium data respectively, and the choice depends on how much data the tablet’s daily work actually uses.

How much data does a scanner data line for business use need?

It depends on how many scans the scanner performs, how much data each scan and sync uses, and whether the scanner application also downloads images, price files or catalogues. There is no single scanner figure in this guide, so confirm the data-only price for that device type on your quote, and size the line from real scan volumes and application data use rather than from a tablet plan price.

Can a POS device data plan handle payments on a small allowance?

Payment data itself is small, so a small allowance can be enough for payments alone. The allowance must also cover everything else the device does — software updates, inventory sync, menu or catalogue downloads — and reliability at the till matters more than allowance size. Confirm the data-only price for that device type on your quote, test coverage at the till, and plan backup connectivity if payments cannot afford an outage.

Which business data only lines suit laptops working away from the office?

Laptop Premium at $40, with 125GB of premium data and a maximum of 3Mbps after that allowance, is the published DataConnect laptop option. It suits laptops used for cloud work, video meetings and file transfers, but a laptop that works all day away from Wi-Fi should be sized from its real usage, and its allowance should be reviewed after the first month of actual use.

Do data only lines for business devices include hotspot allowances?

Tablet Premium includes 20GB of hotspot per line, which covers occasional sharing of the tablet’s connection with another device. Other DataConnect plans in this guide are described by their premium data allowances, and hotspot use should be confirmed on the quote for the exact device type and plan, rather than assumed to be included or unlimited.

Should business data only lines be pooled or kept individual?

That depends on how the quote describes pooling for your device types. Pooled arrangements share an allowance across devices, which can help when some devices use little and others use more, but they can also hide a device that is consuming far more than expected. Individual lines make each device’s cost and usage visible. Ask how pooling works, what happens when the shared allowance is exceeded, and how the bill shows it, and get the answer on the quote before choosing.

In short, a data-only line is a practical tool, not a complicated product: match the line to the device’s real work, confirm the price for that device type on your quote, test it where the device actually works, and review it quarterly. Do that, and scanners, tablets and point-of-sale devices will stay connected without becoming a billing mystery.
