How the $15 per line pricing works

Example with 4 eligible smartphone lines on Advanced 3.0:
Plus taxes and fees. Eligible AutoPay and paperless billing are required for the $40 Advanced 3.0 example pricing. Plan pricing, promotional qualifications and offers are subject to change.

- Eligible lines receive $25 per month in promotional bill credits.
- The credits continue for 24 months, for up to $600 per eligible line.

Starting a New Business? Bringing Your Own Phones Can Reduce Upfront Costs
A newer or recently established business can apply for AT&T Business wireless using its Federal Tax ID. AT&T still performs a business credit review, but its updated credit policy has eliminated the former refundable service deposit for affected small-business and mid-market accounts.
If your business already owns compatible unlocked smartphones and brings those phones to AT&T, you are also not purchasing new phones from AT&T. That means there is no new equipment value on which to calculate a device down payment.
For an eligible business, BYOD can therefore mean opening new AT&T Business lines without the former refundable service deposit and without a device down payment.
Business credit approval is still required. Approval is not guaranteed, and activation charges, taxes, fees and other requirements may still apply.
Why BYOD can make sense for a business
- Keep smartphones your employees already know how to use
- Avoid purchasing replacement phones just to change wireless carriers
- Move existing business phone numbers to AT&T
- Reduce eligible monthly service costs with promotional credits
- Avoid a device down payment when no new phones are being purchased
- Make switching easier for businesses that already have usable equipment
What I check before your business switches
The advertised price is only useful if your lines actually qualify. Before the order is submitted, I can review the details that affect the promotion and the number transfer.
- How many lines you want to move
- Which wireless carrier the numbers are coming from
- Whether the phone numbers meet the port-in requirements
- Whether your current phones are compatible with AT&T
- Whether the phones are unlocked from the previous carrier
- Which AT&T Business plan fits the account
- Whether the lines meet the current promotional requirements
- Expected monthly service pricing and bill credits
Not every setup qualifies. I review the line count, phones, current carrier, plan and available promotion before the order is placed so you understand the expected pricing before moving your business numbers.

Frequently Asked Questions
Do I need at least 4 lines to get the $15 BYOD offer?
This specific bring-your-own-device promotion is designed for qualifying businesses moving 4 or more eligible smartphone numbers to AT&T. If you have fewer than 4 lines, other AT&T Business plan and pricing options may still be available.
Can I keep my current business phones?
Yes, as long as the smartphones are compatible with AT&T, unlocked from the previous carrier and meet the requirements for the offer.
Can I keep my current business phone numbers?
Yes. This promotion is designed around moving eligible existing smartphone numbers from another wireless carrier to AT&T.
Do I need to buy new phones?
No. This offer is specifically for businesses that want to bring compatible unlocked smartphones they already own.
How much is the promotional credit?
Eligible lines can receive $25 per month in promotional bill credits for 24 months, which is up to $600 per eligible line.
When do the bill credits start?
AT&T currently states that qualifying credits start within 2 bills. The lines must remain active and meet the offer requirements for credits to continue.
What happens if I cancel a line?
If qualifying service is canceled, the remaining promotional bill credits for that line stop.
Can a brand-new business apply for AT&T Business service?
A business can apply using its Federal Tax ID. AT&T still performs a business credit review and approval is not guaranteed. Under AT&T's updated credit policy, affected small-business and mid-market accounts are no longer required to pay the former refundable service deposit.
Could AT&T require a down payment?
A device down payment may be required when a business purchases phones from AT&T. If your business brings compatible unlocked phones it already owns, there is no new equipment purchase on which to calculate a device down payment. Other upfront charges may still apply.
Does no service deposit mean there is no credit check?
No. AT&T still reviews the company's business credit. The change affects the former refundable service deposit for affected accounts; it does not eliminate the business credit review.
Your AT&T solution provider can handle porting, transfer PINs, and promo credits for your lines.
