FIELD APPLICATION CHIEF
GSM-based communication technology comes first among wireless communication technologies. Unlike other wireless communication technologies, it eliminates the communication distance and offers unlimited communication. It does not need a modem, an Ethernet cable or a phone to communicate the product where it is located with the outside world via the Internet. Of course, there are some basic needs for this communication without any distance limit. The most important of these is a SIM card with which communication will be made. In current systems, an electronic component capable of GSM-based communication and a plastic SIM card directly connected to this component are used in products that aim to open up to the outside world. Thus, the existing product can successfully communicate with the outside world via the operator that sells the SIM card. Particularly with the concepts of IoT (Internet of Things) and Industry 4.0, machines that manufacture on a huge scale have started to become intelligent until they reach the cars that we use daily and the small household appliances that we all have at home. This becoming smart is of course possible by communicating with each other and their centers. Here, each product needs an electronic component that makes GSM-based communication separately and a SIM card that works together with this component. These SIM cards we used until now were made of plastic material and mounted externally to the existing product. But now this old technology is being replaced by a much more useful new technology. The name of this technology, which has started to be actively used in various regions of the world and has just been put into use in our country, is “eSIM”. eSIM, named after the English abbreviation of embedded SIM card (Embedded Sim), offers several features to its users. In the previous plastic SIM card technology, there were many deficiencies both physically and operationally. A slot was needed for this SIM card to be used. This slot not only increased the cost of the existing product but also created an additional pre-manufacture workload for companies. While manufacturing the product, the companies had to supply individual plastic SIM cards from operators and place them into the products. This caused several problems, such as the SIM card not being inserted correctly, forgotten to be inserted, the SIM card coming out of its slot in a mobile device, or the SIM card being opened and stolen while the product was in the field. The main issue, on the other hand, was the operator change issue that occurred after manufacturing. The device manufacturers who wanted to change their operators had to allocate a huge workforce to manage this process. For instance, take a company that manufactures vehicle tracking devices and has thousands of devices installed on vehicles in the field. Each device has an electronic component that makes GSM-based communication and a plastic SIM card directly connected to this component. This company must work with an operator in order to be able to do this vehicle tracking. If they want to change their operator for some reason, they must access each device in the field one by one and take the SIM cards of the previous operator and insert the new SIM cards of the new operator.
The eSIM technology not only offers convenience before manufacturing but also enables SIM card changes after manufacturing. Therefore, it is a technology that all manufacturers follow closely and want to use as soon as possible. eSIM is actually a physical SIM card just like other plastic SIM cards. On the other hand, unlike plastic SIM cards, the assembly is installed inside the GSM modules during manufacturing. Thus, the end user can use the GSM module directly without inserting an external SIM card. This eliminates all the pre-manufacturing issues mentioned above. But its main benefit is seen after manufacturing. Before this benefit, we want to briefly talk about the eSIM manufacturing process. eSIM is logically the same as other plastic SIM cards that we use in our daily lives. Just as we go to an operator and make an agreement to buy a SIM card, the system works the same way with eSIM cards. Again, integrated eSIMs will be manufactured by operators. These eSIM integrations will be sent to the GSM module manufacturers working as partners and will allow them to manufacture the GSM module in which the eSIM is integrated. Thus, the end users will be able to open their devices to the Internet by purchasing a GSM module with an eSIM integration manufactured by the operator. As can be understood, even if it is an eSIM, when the GSM module initially starts, it will start with its own operator. After this, the end user will be able to change their operator in the eSIM integration by updating the parameters remotely and without having to go near the product. In this particular combination, users will be able to easily change their operators at any time remotely. As much as eSIM is important for manufacturers, the GSM module manufacturers that follow this technology and use it in their products are also becoming important. Because, this is a solution provided as a result of “joint work”. It is impossible to think of the two separately. Ozdisan Elektronik is the distributor of Cavli Wireless, the world’s first manufacturer of eSIM inside GSM modules (with an eSIM chip inside) and also an operator-based platform provider.
American-based Cavli Wireless is both a GSM module manufacturer and a technology company that offers solutions to its customers from a single source by making special agreements with operators in various regions of the world. Cavli Wireless, offering irrefutable solutions to its customers, is not only a module provider but also an internet connection services provider, putting the company far ahead of its competitors. Cavli Wireless provides its customers with a specific control panel via its Hubble platform. With this platform, all customers can track which device is active/passive and activate/deactivate the desired device. They can also easily track which device consumes how much internet quota. With today’s conventional methods, the device manufacturers first contact GSM module providers and purchase GSM modules in several quantities. Then, by contacting the operator again, they receive SIM cards in the relevant quantities. When we consider that these thousands of devices are not sold and put into the field at the same time, a huge workload is created like which SIM card is installed in which device, which SIM card should be activated, which SIM card has expired etc. Cavli Wireless company targets its customers who suffer from such issues and offers several options where they provide both a GSM module and an internet line. Thus, the number of providers to be contacted has decreased, and the workload has been reduced to much lower by performing the entire operation through the same provider. Cavli Wireless aims to win customers not only with this type of business models, but also with bundle business models. The most popular and current of these business models is the Hubble99 business model, defined as follows. When the specified working conditions with Cavli Wireless company is met for the relevant products for three years, the supply of the internet package with the GSM module is billed as only $0.99/month. Thus, the large budget caused by purchasing expensive GSM modules is eliminated for the manufacturing company, and the company can complete its projects with monthly payments from only one source. You can access all Cavli Wireless products and solutions through Ozdisan Elektronik, and experience both the GSM modules and the Hubble platform whenever you want.
