Common AT&T Business terms
These are some of the terms people search for most often on this site.
Upgrade
An upgrade means you are keeping the same line but replacing the phone on it.
This matters because upgrade pricing can be different from new-line pricing.
New line
A new line means you are adding another line of service to the account.
Some promotions only work on new lines.
Bill credits
Most phone deals are not instant discounts. They usually show up as monthly bill credits over time.
That is why the phone may still show a regular price at first.
Installment plan
This is the monthly payment plan for the phone.
Most business phone offers run on 36-month installments.
Trade-in
A trade-in is the old phone you turn in for a promotion.
The final credit depends on the model and condition after it is received and inspected.
Bring Your Own Device
This means you are bringing your own phone instead of buying a new one from AT&T.
Some offers work when you bring your own device and move your number in from another carrier.
Number transfer
A number transfer means moving a number from another carrier to AT&T.
Do not cancel the old carrier first. Keep the number active until the move is complete.
AT&T business transfer pin
A transfer pin is the security code needed when moving an AT&T wireless number out to another carrier.
People also search for this as an AT&T business number transfer pin.
AT&T TOBR
TOBR means Transfer of Billing Responsibility. It moves a line from one AT&T account to another AT&T account.
This is not the same as moving a number to a different carrier.
AT&T Premier login
AT&T Premier is the online portal many business customers use to manage wireless service, billing, and orders.
People also search for this as AT&T Premier business login, AT&T wireless Premier login, or Premier AT&T login.
AT&T LOA (CPNI consent)
This is the quick permission AT&T requires before an AT&T Solution Provider can review limited business account information for pricing, promotions, and eligibility.
It allows account review only. No changes are made without your approval.
AT&T Unlimited Your Way
Unlimited Your Way is the main AT&T business phone plan path for many accounts, especially smaller accounts that want to mix plan levels by employee.
Standard, Advanced, and Premium can be mixed on the same account depending on each user’s needs.
AT&T business promotions
These are the current business offers for upgrades and new lines, including phone deals, trade-in offers, and credits.
Most promotions apply as monthly bill credits, and eligibility should be checked before the order is placed.
AT&T business activation guide
This is the step-by-step process for turning on a new line or upgraded device after it arrives.
You usually need the wireless number, billing ZIP code, Wi-Fi for eSIM setup, and sometimes a separate eSIM download after activation.
SIM card
A SIM card is the physical card inside the phone that connects it to service.
Some phones still use a physical SIM.
eSIM
An eSIM is a digital SIM built into the phone.
Many newer phones use eSIM instead of a physical card.
