Does the 4G module require a card? Can I access the Internet by inserting a card?

In homes and businesses, stable networks are needed to support various applications. In the process of meeting this demand, 4G modules have undoubtedly become the choice of many people. But for many people, they don’t know whether the 4G module requires a card, and whether the card can access the Internet. Therefore, this article will answer these questions for you.

Let’s answer a common question, that is, does the 4G module require a card ? In fact, the 4G module needs to insert a SIM card . This is because the SIM card stores the user’s mobile phone number and network authentication information, which is an important credential for network operators to identify the user’s identity. Therefore, if you want to use the 4G module to access the Internet, you must insert the SIM card into the 4G module.

So, after inserting the SIM card, will you be able to access the Internet smoothly ? In fact, it’s not just as simple as inserting the SIM card. After inserting the SIM card, you need to configure and set up the 4G module accordingly, including accessing the operator’s network, setting APN parameters for Internet access, etc. Only after completing these configurations can you successfully access the Internet. Therefore, inserting the card does not necessarily mean that you can access the Internet, and further configuration and settings are required.

In addition, it should be noted that different 4G modules may have different requirements for SIM cards. Some 4G modules require the use of Micro SIM cards, while others require the use of Nano SIM cards. Therefore, before purchasing a 4G module, you also need to confirm the type of SIM card you are using to avoid unnecessary trouble.

In general, the answer to the question of whether the 4G module requires a card is yes, it can only be used if the SIM card is inserted. However, inserting a card does not necessarily mean that you will be able to access the Internet smoothly. Corresponding configuration and settings are also required. In addition, before purchasing a 4G module, you should also confirm the type of SIM card you are using. I hope this article can help everyone have a clearer understanding of 4G modules.
