    AT&T 5G SIM benefits

    • 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.

    Bringing your own AT&T phone to the new carrier is easier than you may think. Once you know that the AT&T coverage serves your area, all you need to do is follow these simple steps:

    1. Pick a carrier. Choose the right AT&T MVNO for your usage and budget. As always, make sure you read all the fine print.
    2. 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.
    3. Check phone compatibility. You can check phone compatibility on the carrier's site before signing up.

    2. Press gently until the SIM tray pops up, you do not need to use much pressure.
    3. Pull the SIM tray out gently, be careful the SIM card does not fall out.
    4. Swap your SIM card over, making sure you have aligned the SIM in the correct position.
    5. Re-insert the SIM tray into the phone.
