AT&T Business Unlimited Plans: $600 BYOD + Port-In Bill Credit Per Line
Bring your own compatible smartphone (BYOD). Port your number in from another carrier. Activate a new line on an eligible AT&T Business Unlimited plan (Advanced or Premium). Get bill credits that can cut your monthly wireless cost.
What you get
- $600 total bill credits per qualifying line
- Often applied as monthly credits over time (commonly 24 months ≈ $25/month)
- Keep your existing phones if they’re compatible
Fast definitions (so there’s no confusion)
- BYOD = you bring your own smartphone (no new phone purchase required)
- Port-in = you move your phone number from another carrier to AT&T
- New line = a newly activated line of service (not just an upgrade)
Eligibility checklist
- BYOD smartphone: Your phone must be compatible and unlocked (if required).
- Port-in number: You’re bringing a number from another carrier (you’ll need the port/transfer info).
- Activate a new line: The credit is tied to a new line activation on eligible AT&T Business Unlimited (Advanced or Premium).
Quick math: what does $600 really do?
Net line cost = (your plan price per line) − (monthly BYOD/port credit)
| Scenario | Example plan price per line | Example monthly credit | Example net plan cost per line |
|---|---|---|---|
| Example only 5 lines on Unlimited Advanced | $45/line | $25/line | $20/line (plus taxes/fees) |
| Example only 5 lines with an AutoPay discount applied | $35/line | $25/line | $10/line (plus taxes/fees) |
Adding 11+ new lines? You may have a better BYOD option.

FAQ
Do I have to buy new phones to get the credit?
No. This is a BYOD offer. You bring your own compatible smartphone.
Do existing AT&T business customers qualify?
Yes, when you’re adding a new line and porting in a number from another carrier on that new line. Upgrades alone usually don’t qualify for a port-in credit.
When do the credits show up?
Often within 1–2 billing cycles. If they don’t appear on time, I help you chase it down.
Can this stack with other offers?
Sometimes yes, sometimes no. Stacking rules vary by promotion. I’ll confirm what’s allowed for your exact order.
What if I don’t want to set up AutoPay?
You can still get the BYOD/port-in credit if you meet the requirements. AutoPay mainly impacts your base plan price (discount depends on payment method).
What if I’m adding 11+ lines and don’t want to port numbers?
Then you should look hard at Business Preferred E Turnkey — it can offer BYOD pricing without a port requirement.
Promotion terms and availability can change. I’ll validate your eligibility and quote the correct pricing based on your line count and setup.
