Do I need to change SIM to use 5G network?

Since the time when network operators in Vietnam began to cover 5G nationwide, many people have asked whether using the current SIM can connect to 5G or not and who needs to change SIM to use the latest 5G network? In response to this question, a representative of a network operator in Vietnam said that people who are using physical SIM that supports 4G connection can still use this type of SIM to use the 5G network. Meanwhile, users who are using eSIM only need to register for a 5G package to use without having to re-register or change to a new SIM.

This person added that only those who are using a regular SIM (standard SIM) need to change to a new SIM to use newer network technologies, because this type of SIM usually only supports 2G or 3G networks.

How to check if your current SIM supports 4G network or not

As mentioned above, any SIM that supports 4G network can continue to use 5G network without having to change to a new SIM. So how do you know if the SIM you are using supports 4G network or only supports up to 3G network? - For Viettel users: If you are using Viettel network, you activate the calling function on your smartphone and enter the character sequence *098*4#, then press the call button. The system will display a notification dialog box, you enter the number "1" and press the send button. Wait a moment, if the message "You are using Viettel's 4G SIM" appears, it means you can continue to use your current SIM to connect to 5G without having to change to a new SIM.

- For VinaPhone users: If you are using the VinaPhone network, activate the calling function on your smartphone and enter the character sequence *091*38#, then press the call button. The system will send a notification stating whether the user's SIM supports 3G or 4G network, from which you will know whether you need to change SIM to use 5G network or not. - For Mobifone users: Currently, Mobifone network does not support checking 3G or 4G SIM using the syntax like Viettel and VinaPhone. If you are using Mobifone network, you can call the support center of this network to ask for help checking. In addition, a simple way to check is for the user to activate the mobile network connection function on the smartphone. If the 4G+ or 4G, 4G LTE network icon appears, it means that the SIM supports 4G network connection. On the contrary, if the network icon only displays 3G or H+, it means that the SIM only supports 3G network. However, this checking method is not completely accurate because the smartphone the user is using may only support up to 3G network, so it does not display the 4G connection notification, even though the SIM supports 4G network. The 4G icon is usually printed on SIM cards if it supports 4G connection. Users can remove the SIM from the phone to check this detail more closely.

What do users need to use 5G network in Vietnam?

To use the 5G network in Vietnam, users need to ensure the following factors: - First, users must be using a smartphone or mobile device that supports the 5G network. Currently, 5G-supported smartphone models in Vietnam have "soft" prices and are more accessible, so you can completely own a 5G phone to experience the latest network technology. Readers can refer to the list of affordable 5G phones introduced by Dan Tri here. - The 5G connection feature must be activated on the smartphone. Readers can follow Dan Tri 's instructions here to do this. - Users must use a subscription from a network operator that provides 5G service and must be in an area with 5G network coverage. Currently, most major network operators in Vietnam have provided 5G service and coverage has expanded almost nationwide.

Does using 5G network consume more data than 4G network?

The advantage of the 5G network is that it is 10 to 100 times faster than the 4G network. However, after a period of experiencing the 5G network, many users believe that this network technology consumes more data than the 4G network. In fact, if you use the 5G and 4G networks to do the same things on your smartphone, such as watching videos at the same resolution, downloading the same file or watching live content on social networks... the mobile network capacity will be consumed the same. However, because the 5G network has a faster download speed, users will feel that the data capacity is consumed faster in a short time.

However, due to the faster speed of 5G network, users often tend to use many internet-connected applications at the same time such as watching high-quality movies, making high-quality video calls, etc. In addition, some applications will automatically optimize video and image quality to match the high speed of 5G network, which will cause mobile network capacity when using 5G to be consumed more. Therefore, depending on the purpose of use and 5G package, users can choose 4G or 5G network connection settings to suit and save the most costs. However, for basic tasks such as surfing the web, social networking, etc., the difference in usage capacity between 4G and 5G networks is not really significant, so users are not really too concerned about this issue.
