AT&T 3 line plan benefits
We love Mobile Virtual Network Operators or MVNOs. If you're on the lookout for cheap prepaid phone plans, they're the best route to go down.
Want to stay on the same network, keep your phone and number, plus get greater flexibility?
Yep. You've got it. Forget the major carriers. Plans include everything you need, but come at a much better price with an MVNO.
- Same great nationwide coverage: These cell phone carriers operate on the very same networks as the big three carriers.
- Much lower prices: Save up to $600 per year on your cell phone plan. Why are MVNOs so much cheaper? They don't have the huge overhead and advertising costs the big guys do.
- No contracts: Don't get trapped into a two-year agreement. Switch carriers when you decide to with a no contract phone plan.
- Same cell phone service: Just because you're paying less, that doesn't mean you have to scrimp on features. Plans with unlimited everything are easy to find from these prepaid carriers. Usually, a low-cost carrier plan comes with unlimited talk and text as standard, high-speed data, and even mobile hotspot data features.
- Keep your phone and number: You can bring your own phone and keep your phone number. No need to sign up for pricey device payments.
- Customize your plan: You decide how much data you need. Choose to pay as you go, opt for unlimited or no data, minimal minutes, or unlimited talk text and data. Unlimited data plans come at a much better price with an alternative carrier. Pick the plan options that fit your budget - not the one your carrier thinks you need.
- Great customer support: Smaller mobile providers are known for their attention to their customers. Stop feeling like an anonymous number getting lost in the crowd! Check out our carrier user reviews before switching.
AT&T 3 line plan features
- 4G LTE and 5G data speeds: Since AT&T MVNOs are all powered by the AT&T network, you'll pay less without sacrificing speed.
- Unlimited talk and text messaging: Finding a new unlimited plan has never been easier. Virtually all small carriers include unlimited text and calls in their plan options. Compare cheap talk and text plans with or without data.
- International calls to Canada and Mexico: International calling is a must for many people. Luckily MVNOs offer some of the best international phone plans, with free calling to certain countries like Canada and Mexico, and discounted rates on others.
- Multiline discounts: Low-cost carriers also offer some of the cheapest family cell phone plans, with multi-line discounts.
- Wi-Fi calling: This feature is handy when you're out of your service area, allowing you to make calls over the internet instead of on your cellular connection.
- Tethering/hotspot data: Many low-cost carriers allow you to use your phone as a hotspot. Pick an MVNO with the best mobile hotspot plans so you can share your mobile hotspot data with other devices.
- HD video streaming: Just like the big guys, some MVNOs offer HD video streaming and some don't. Read the fine print to find the option you want.
Switch to a cheap AT&T 3 line plan
Switching carriers is way easier than you think. You can even bring your own AT&T phone to the new carrier. Once you know that the AT&T coverage serves your area, all you need to do is follow these simple steps:
- Pick a carrier. Choose the right AT&T MVNO for your usage and budget. As always, make sure you read all the fine print.
- Choose a plan. Now that you know how much data you really need you're totally in control. Pick a plan that meets your needs without costing you extra for unnecessary data.
- Check phone compatibility. This really comes down to the type of technology used on the network. AT&T and T-Mobile use GSM vs CDMA which is what Sprint and Verizon Wireless use. If you already own an AT&T device you should be good to go.
