You have a ZTE phone, N818S model specifically, and you want to know ZTE N818S Sim Card Location.
Before you keep reading, make sure you read ZTE N818S manual to check your phone is actually an N818S model.
Best Answer:
It’s an old CDMA phone that doesn’t support 4G and thus doesn’t use a SIM card. These old CDMA phones can typically only be activated on the network that they were sold on.
I suggest you keep reading as we’re going to cover more helpful details.
ZTE Corporation is a Chinese partially state-owned technology company that specializes in telecommunication. Founded in 1985, ZTE is listed on both the Hong Kong and Shenzhen Stock Exchanges.
ZTE’s core business is wireless, exchange, optical transmission, data telecommunications gear, telecommunications software, and mobile phones. ZTE primarily sells products under its own name, but it is also an OEM.
In today’s post, we’ll see why there’s no sim card location on ZTE N818S model. Along with providing answers to the most frequently asked questions, we’ll also look at What is a CDMA phone.
Let’s dive right in.

ZTE N818S Sim Card Location
The sim card slot doesn’t exist on that phone. It is a CDMA phone which means the phone number is tied to the phone and not a SIM card, this phone is activated.
My guess the reason why it’s CDMA is that the phone is given by the US government so there’s no reason to switch out SIMs.
What happens When They Switch Off your 3G Network?
Phone companies must keep up with the latest technology, and they do not want to maintain obsolete technologies. They are expensive to maintain and take up space that could be better used for newer hardware.
Removing older masts frees up space for 5G equipment and simplifies network management; additionally, some 3G spectrum can be used for 4G data. (However, it is not suitable for 5G.)
Carriers in many countries have announced the shutdown of 3G networks, as well as 2G networks if they are still in use.
Since N818S model only supports 3G (matter of hardware), it will become obsolete without a 3G network.
What is CDMA and How Does it Work?
CDMA, which stands for Code Division Multiple Access, is a competing cell phone service technology to GSM on older networks that are gradually phasing out. In 2010, carriers worldwide switched to LTE, a 4G network that supports simultaneous voice and data use.
Which Networks Are CDMA?
Of the five most popular mobile networks in the United States, Sprint, Verizon, and Virgin Mobile use CDMA. T-Mobile and AT&T use GSM.
How Does CDMA Work?
CDMA uses a “spread-spectrum” technique whereby electromagnetic energy is spread to allow for a signal with a wider bandwidth. This approach allows several people on different cell phones to be “multiplexed” over the same channel to share a bandwidth of frequencies.
CDMA technology separates data and voice packets using codes and then transmits them using a wide frequency range. Because CDMA allocates more space for data, it became appealing for high-speed mobile Internet use
CDMA vs. GSM
Most people do not need to be concerned about which cell phone network they select in terms of which technology is superior. However, there are significant technical differences between the two standards.
CDMA Coverage
While CDMA and GSM compete for faster bandwidth speeds, GSM provides more comprehensive global coverage due to roaming and international roaming contracts. GSM technology tends to cover more rural areas in the United States than CDMA technology.
Device Compatibility and SIM Cards
It is simple to swap phones on a GSM network because GSM phones use removable SIM cards to store information about the user on the GSM network, whereas CDMA phones do not. CDMA networks, on the other hand, use information on the carrier’s server to verify the same type of data that GSM phones store in their SIM cards.
Because of this data-storage design, SIM cards on GSM networks are interchangeable. If you’re on the AT&T network and have an AT&T SIM card in your phone, you can remove it and insert it into another GSM phone, such as a T-Mobile phone, to transfer all of your subscription information, including your phone number.
What this effectively does is let you use a T-Mobile phone on the AT&T network.
- An easy transition is typically not possible with most CDMA phones, even if they do have removable SIM cards. Instead, you typically need your carrier’s permission to perform such a swap.
Because GSM and CDMA are incompatible, you can’t use a Sprint phone on a T-Mobile network or a Verizon Wireless phone on an AT&T network. The same is true for any other device and carrier combination you can concoct from the above CDMA and GSM list.
CDMA phones that use SIM cards do so either because the LTE standard requires it or because the phone has a SIM slot to accept foreign GSM networks. Those carriers, however, still use CDMA technology to store subscriber information.
Simultaneous Voice and Data Usage
Most CDMA networks do not support simultaneous voice and data transmissions. This is why, when you end a call on a CDMA network like Verizon, you may be inundated with emails and other Internet notifications. While you are on a phone call, the data is essentially paused.
However, when you’re on a phone call within range of a Wi-Fi network, two-way data exchange works just fine on a CDMA network because Wi-Fi, by definition, does not use the carrier’s network.
