The best Prepaid CDMA SIM card in May

CDMA stands for Code Division Multiple Access. It's one of the main technologies used for cell phone service in the US. You also may have heard of GSM, which is the other technology used worldwide for cellular service. Which network you use depends on your carrier.

Verizon and Sprint hook onto the CDMA network while T-Mobile and AT&T use GSM.

There are some great deals to be had with low-cost online carriers, known as MVNOs. These piggyback onto the main networks using CDMA technology. You can save up to 50% off your cell phone bill with one of these prepaid carriers.

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.

How to switch to a 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.

Things to figure out before you switch

    • 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.

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.

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

Can I change a GSM SIM to a CDMA SIM?

When you sign up with a GSM or CDMA carrier you'll receive a new SIM card. However, if you're looking to put a GSM SIM into a CDMA phone you'd need to check if the phone is compatible as older CDMA phones do not have a SIM card slot.

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 CDMA use SIM cards?

CDMA phones didn't use SIM cards until recently. Due to the LTE technology CDMA phones have had to start using SIM cards to be able to access the 4G LTE network.

Why does my CDMA phone have a SIM card?

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

Recap

There's a number of options with a CDMA SIM card and plenty of cheap cell phone plans that can save you money on your phone bill.

All of the providers encourage you to bring your own phone, but make sure to check with the carrier that your phone is compatible. You can also check out our guide on how to unlock your cell phone.

Still can't decide? Pop over to the prepaid phone plans page with deals from all low-cost carriers on both the CDMA and GSM network.
