Purchasing a phone plan for two lines with AT&T will save you money compared to getting two separate plans. For example, the AT&T Premium 2.0 plan—our pick for the best AT&T unlimited plan for two lines—would cost you $90/line if you purchased them separately. By combining two lines on the same plan, the price would drop to $80/line. That's a total savings of $20/month.
If you and your partner, family member, or friend are on individual phone plans, it might be time to merge them into one. Read on to check out our favorite AT&T phone plans for two lines.

Best AT&T Unlimited Plans for 2 lines
Unlimited plans are AT&T's bread and butter, and it's why you see almost all of AT&T's marketing geared towards these offerings. Here are WhistleOut’s picks for the best unlimited AT&T 2-line plans.
Premium 2.0 | $90/line—Best overall unlimited plan for 2 lines
At $90/month for a single line, the AT&T Premium 2.0 plan is the carrier's most expensive plan, but the per-line price lowers to $80/line if you sign up for two. This plan also provides some attractive perks for that high price tag. You’ll get unlimited talk, text, and data in Mexico and Canada.
There’s also no need to worry about going over any premium data limits because all of your data on the Unlimited Premium plan is premium. AT&T will not slow you down in favor of others, no matter how much data you use on its 4G LTE and 5G network. And you can keep your other devices connected while on the go with 40GB of dedicated mobile hotspot data.
If your school or business participates in AT&T's Signature Program, you can take another $10/month off per line. That's still pricey, but if you and your partner are heavy phone users and fans of HBO Max (it really is one of the best streaming services), we think this plan is very hard to beat.
- Pros: Filled with perks, never deprioritized, 100GB of mobile hotspot data, 4K streaming
- Cons: It's expensive
Extra 2.0 | $70/month—Best mid-tier unlimited
AT&T's Extra 2.0 is its best mid-tier unlimited option... alright, it's AT&T's only mid-tier unlimited plan.
For a single line, the Extra 2.0 plan would cost you $70. With two lines, though, that goes down to $60/line. This plan isn't as perk-heavy as the Premium 2.0 plan, but it still boasts impressive features. You'll get 100GB of premium data per line (speeds may be slow in network congestion after 100GB), which is not as good as unlimited premium data, but it’s still very generous. Most users will never come close to using that much data.
However, the drop in mobile hotspot data is pretty dramatic. The Premium 2.0 has 100GB of hotspot data, while the Extra 2.0 plan includes 50GB, which is still a hefty amount.
- Pros: High priority data limit, less expensive than Premium 2.0
- Cons: Low mobile hotspot limit
Value 2.0 | $50/line—Cheapest AT&T unlimited plan
The AT&T Value 2.0 plan is as bare-bones as you can get from a postpaid AT&T unlimited phone plan. It includes unlimited talk, text, and data (5GB of premium) for just $50/line ($45/line for two plans). You’ll also get 3GB of hotspot data per line, which may be insufficient if you want to connect your laptop or other devices regularly. The Starter plan is a simple, no-frills plan, but for many, it is sufficient.
- Pros: Least expensive AT&T postpaid unlimited plan
- Cons: 5GB priority data, very low mobile hotspot limit

Best Limited Data
AT&T Plan for 2 lines
Unlimited plans are not for everybody—if you are trying to save money on your phone bill, you should look into a limited-data option. Here is our pick for the best 2-line AT&T plan with limited data.
4GB Plan | $45/line—Best limited data plan for 2 lines
Shhh. Don't let my bosses know this is the only postpaid limited plan for two lines from AT&T. I'm planning on telling them this was a very hard article to research. "How am I supposed to pick the best plan from all these great choices?!? Give me a raise!"
The 4GB plan is usually $50/month for a single line. With two lines, you'll pay $45/line. The savings aren't huge, but it's a relatively inexpensive plan at the end of the day. As you might expect, this plan does not include many perks. You only get 4GB of data per line each month, which is on the low end of average usage, so you’ll want to keep an eye on your data use.
Thankfully, there are no overage charges, but AT&T will slow you down after reaching the 4GB threshold to almost unusable speeds. There’s also no dedicated hotspot data on this plan, but you can use the hotspot feature against the plan's 4GB data allotment.
- Pros: Low price
- Cons: No dedicated hotspot, data limit may be tight for some users

Best AT&T Prepaid Plan for 2 lines
10GB Prepaid plan| $25/line—Best cheap AT&T plan for 2 lines
You can get great AT&T coverage for both you and your bae for way less when you opt for a prepaid family plan. When combined into a 2-line family plan, AT&T's 5GB prepaid plan gets a $10 total discount, bringing the cost down to just $25 per line.
Here's how it works: Each person gets unlimited talk and text, plus 5GB of data per line. You don't have to share the 10GB between you, which is great if one of you happens to be a bit of a data hog (no judgment here!). Both lines have hotspot access, but note that it will come out of your high-speed allotment. If either of you goes over that 5GB, you won't be cut off from your data or charged overage fees—your speeds will simply slow to a crawl (around 128kbps, or 2G speeds). AT&T's prepaid plans also include access to their 5G network, so you can enjoy super speedy downloads where you need them.
As long as you're a relatively light data-using duo, this plan is an excellent way to get on AT&T's network without breaking the bank from traditional postpaid plan pricing.
- Pros: Only $25/line; no overage fees or true data caps; 5G network + hotspot access included; data rolls over month to month
- Cons: Can be easy to exceed 5GB per line; hard throttle limit; SD-quality video only

alternative for 2 lines
Cricket Wireless | Supreme Unlimited | $45/line—Best alternative 2-line prepaid plan on AT&T's network
Cricket is an AT&T-owned-and-operated MVNO that offers the same great coverage for often a fraction of the price—and it's Supreme Unlimited prepaid plan is actually more enticing in a lot of ways than the prepaid offerings from Big Blue itself.
With the Cricket Supreme Unlimited plan, you get unlimited premium data and 50GB of dedicated hotspot data. You also get perks like 150GB of cloud storage and HBO Max with ads. However, you'll only pay $45/line (usually $55 on a single line plan) each month. That pairing of perks and pricing offers more value than anything you can get from AT&T Prepaid. Our only issue with this plan is that we wish the hotspot limit was higher.
- Pros: Unlimited priority data, HBO Max with ads, just $45/line
- Cons: Slightly more expensive per line than on MVNOs
