    Cheapest CDMA SIM card in 2022

    By Rob Webber - Last updated on

    At MoneySavingPro our priority is to save you money, and to make finding the best CDMA SIM card easy for you.

    CDMA - Code Division Multiple Access, is a technology used for cell phone service in the US and the main network using CDMA is Verizon.

    Verizon is known for its expensive plans, but with Mobile Virtual Network Operators (MVNOs) that's not something you have to worry about. With a Verizon MVNO you'll have access to the same nationwide coverage, but their plans start at around $15 a month.

    To find out more check out the CDMA SIM card plans we've compared for you below.

    What is a CDMA SIM card?

    Using a SIM card makes it easier to switch plans between phones and carriers. This tiny card stores all your information, including contacts and personal data. It connects you to your carrier's network.

    There are three different SIM card sizes and you'll need to check which one your phone uses before switching providers.

    The three types of SIM cards are;

    • Standard SIM
    • Micro SIM
    • Nano SIM

    Nano SIM is the most common and is used in the latest smartphones including newer Apple iPhone and Samsung Galaxy models.


    Which carriers are CDMA?

    Below is a list of CDMA alternative carriers piggybacking off the Verizon and Sprint network. Make sure to check our coverage map if you're not sure which network is the best for your area.

    You'll be sent a CDMA SIM card kit in the post from your new carrier that you can pop into your phone with simple activation instructions. If you're not sure if your phone is compatible, make sure to check the carrier's site before signing up.

    Don't worry if your phone isn't compatible. You can still save money with a refurbished phone. Check out some of the latest refurbished phone deals.

    Switch to a cheap CDMA carrier

    Switching providers can be a great way to save money. There's a range of low-cost alternative carriers that hook onto the main US networks. Sprint and Verizon are the two networks running on CDMA. This means you can get the same great service you love. Plus, with a low-cost carrier you only pay for what you need.

    Most online carriers encourage you to bring your own phone. This is a great way to save money. If your phone is already with Verizon or Sprint you should have no problem bringing your device across to a CDMA SIM card.

    However, some phones are locked to the carrier's network. Make sure to check your phone is unlocked before bringing it across. You can check your phone's compatibility by heading over to the carrier's website.

    Comparing CDMA SIM card plans

    • How much talk, text and data do you need? With low-cost online carriers you can tailor a plan to your needs. By keeping track of your usage you can save money and easily update your plan if needed. To check your average data you can use our data usage tool.
    • Bringing your own phone? If your phone is unlocked and compatible with a CDMA SIM card this is a great way to save money.
    • Who offers the best coverage? You can use our coverage map to find out which network and carrier works best in your area.

    CDMA vs GSM

    Is CDMA better? Whether CDMA or GSM is better comes down to personal choice and depends on what your cell phone needs are.

    To fully understand how these two work, we need to talk about the (relatively) new tech in town; LTE. As we became hungrier for faster, more reliable data speeds, the LTE network was born. It was created for data only, but relies on GSM and CDMA for voice and text. CDMA and GSM fill in the gap when 4G LTE is not available.

    The GSM network is used worldwide, so this makes it a good choice if you're a frequent traveler. You can save money with a GSM phone by buying a local SIM from the country you're visiting.

    CDMA phones once stored data on the phone directly, rather than a SIM card. However, phones made in the last few years are already unlocked. They run on both the CDMA and GSM network to work alongside LTE.


    CDMA SIM card FAQs

    What is CDMA?

    CDMA (Code Division Multiple Access) is a network technology that Verizon and Sprint use. It's used mainly in the US, unlike the GSM network which is used worldwide.

    Does my CDMA phone need a SIM card?

    All modern CDMA phones have a SIM card to enable the use of the 4G LTE network.


    Recap

    Low cost carriers offer plans that could save you up to $600 per year.

    Finding the best CDMA SIM card can come down to a number of factors including how much you want to spend, what features you're looking for, and coverage in your area.

    The great thing about MVNOs is they make it easy to bring your own phone. As long as it's unlocked and compatible with the CDMA network you'll be up and running within a few days. You can check your phone is compatible with our free tool.
