With the gradual popularization of 5G mobile phones and **, many friends are more concerned about whether the 5G traffic card can be used in 4G mobile phones.
A 5G data card can be used on a 4G phone. The so-called 5G traffic card, refers to the SIM card that provides users with 5G standard network services, when used with 5G mobile phones, and is within the coverage of 5G network, then you can enjoy 5G standard network services, but based on the particularity of 5G network and technical standards, it will be backward compatible with 4G and network, and this means that even if the mobile phone is a 4G mobile phone, you can also use the 5G mobile phone card, but based on the limitations of the mobile phone processor, you can only enjoy the 4G standard network service.
In addition, whether it is a 4G mobile phone card or a 5G mobile phone card, it belongs to the *** SIM card, also known as the Naro SIM card, it is compatible with 4G and 5G mobile phones, so the SIM card is universal.
SIM card has gone through many iterations, far from it, let's say that the iteration of the last two generations of SIM cards, the previous generation of SIM cards is also known as micro SIM cards, and its shape is a special pentagonal type, as shown below:
The only difference between it and the Naro SIM card is that the bezel is larger, and the SIM card provided by major domestic operators will have a bezel on the outside, which is actually to help users change the Naro SIM card to a micro SIM card, and it is also to adapt to some 3G or 4G models.
Therefore, it can be determined that the 5G data card belonging to the Naro SIM card can be used in a 4G mobile phone.
Without considering the brand, model, and performance of accessories, the biggest difference between 4G mobile phones and 5G mobile phones is the processor, the processor carried by 5G mobile phones supports access to 5G and below networks, while the processors carried by 4G mobile phones support access to 4G and below networks, but 4G mobile phones can also access 5G networks. However, it should be noted that access is one thing, and enjoying the corresponding standard network service is another.
Therefore, when we put the 5G data card into the 4G mobile phone, although it can be used normally, based on the limitations of the mobile phone, without considering the external network coverage, when using the 4G mobile phone with the 5G traffic card inserted, although it enjoys the 4G standard network service, it consumes 5G traffic.
Conclusion: For ordinary users, there is no need to know how many G the mobile phone card is, the so-called 4G mobile phone card, 5G mobile phone card, refers to the mobile phone**, and the decision on whether the mobile phone card can be used normally is the shape of the mobile phone card, although the super SIM card has come out, but most users use the SIM card is Naro SIM card, so they are universal.
