Exciting facts about 5G SIM card: The first and most important database is inside the mobile phone: the Subscriber Identity Module (SIM). Previously we have seen the 2G,3G and 4G SIM cards but now we will see the 5G SIM card soon. Here I would like to explain in short about SIM cards- The SIM is a small memory device mounted on a card and contains user specific identification. The SIM card can be taken out of one mobile equipment and inserted into another. In the GSM network, the SIM card identifies the user just like a traveller uses a passport to identify himself. 5G SIM card will be same physical look as previous but something will be different in technology.

Same as previous the 5G SIM card contains the identification numbers of the user, a list of the services that the user has subscribed to and a list of available networks. In addition, the 5G SIM card contains tools needed for authentication and ciphering and, depending on the type of the card, there is also storage space for messages such as phone numbers, etc. Many countries aiming to introduce the 5G Internet by the year of 2019-2020. A 22-member committee is working to launch the 5G Network soon.

What is the Exciting Facts About 5G SIM Card 
5G speed is expected to range from 1GBPS to 100GBPS. 5G will use various transfer speeds and recurrence so we require that sort of Smartphone that can support 5G services. Barely any organizations have just begun making 5G perfect gadgets. Approximately, the 5G Services will be launched in late 2018 or in First quarter of 2019. People are Eagerly Waiting for 5G Mobile Devices, Routers, SIM Cards to experience more fast Internet data and Quality voice calls than 4G Technology.

Many friends ask a question that 4G SIM smartphone support 5G SIM cards? Perfect answer is that we all knows that SIM cards don’t have radios. They aren’t “5G” (or 4G, 3G, LTE or whatever). SIM cards only contain data (carrier info, some customer info, etc.).The phone itself has the radio and if the radio supports 5G. Technically all SIM cards have the same function like-The area is connected through an air interface to a database known as a Visitor Location Register (VLR). The VLR is integrated into a telephone exchange known as a Mobile Services Switching Centre (MSC). The home operator of the subscriber also needs to know the location of the subscriber and so it maintains another register - just as the embassy did in our example - which is called a Home Location Register (HLR).

The HLR stores the basic data of the subscriber on a permanent basis. The only variable data in the HLR is the current location (VLR address) of the subscriber. However, in the VLR, the subscriber data is stored temporarily. When the subscriber moves to another VLR area, its data is erased from the old VLR and stored in the new VLR.

Why should You upgrade to 5G SIM?
Sure you will get the benefit of Superfast speeds, Very low latency, Improved user experience, Whole new technologies being enabled.SIM card sizes have changed several times already, going from standard, to micro, to nano, so there’s a good chance that by the time 5G comes around they’ll be smaller still. But you’ll also need a 5G-compatible SIM card.

More important is that you will get the superfast speed 1-10Gbps. Already 5G trials are taking place, with Verizon in the US for example showing that its technology can achieve download speeds of 30-50 times faster than 4G. 10Gbps is widely accepted as a realistic expectation for 5G when it is fully commercially available, but it’s unlikely that early services will achieve such speeds from the outset. Even if the networks can support such speeds we will all need compatible high-end smartphones to be able to exploit them.

All these things are made possible due to completely new technologies used in 5G SIM. 5G SIM will completely change the mobile network situation  5G will provide much higher speeds with great reception everywhere that was not possible in earlier networks.
