Recently, as more and more people open after purchasing a self-sufficient phone, let’s look at how to open a self-sufficient phone and why and how to change to a carrier. If you have purchased a self-sufficient phone but do not know how to use it, please read this post carefully and hope it will help you a little.
Self-sufficiency phone concept
First, you need to grab the concept of self-sufficient phone. Self-sufficient phone can be simply said to be air. Rather than opening a device at a telecommunications agency or retail store, you purchase a device online or at a manufacturer’s offline store. Literally, it has nothing to do with whether you purchase the device and use it after opening it or using it as an air conditioner without opening it. Just think of it as buying something. I briefly explained the concept of self-sufficiency phone, but if you want to check it in more detail, you can refer to the meaning, advantages, and disadvantages of self-sufficiency phone in the post below.

Mobile phone terminal self-sufficiency phone meaning and advantages and disadvantages. 좋은뉴스
What do you mean by terminal self-sufficiency phone? Simply put, the self-sufficient phone can be seen as a system that leaves the purchase of SIM chips and terminals to the discretion of the customer. This can be done in the form of air machines at electronic product stores or open markets without going through telecommunication companies.

Summary of how to open a self-sufficient phone
If you are using an existing mobile phone, you do not need to open a self-sufficient phone. Let’s look at the method in order by user type.
You are using your old phone
Buy a self-sufficient phone.
When you receive a self-sufficient phone, check the SIM of the existing phone.
If the SIM size is the same, insert it directly into the self-sufficient phone.
Check if the phone or data can be used normally.
Move the information in the existing mobile phone to a switch or migration.
It can be summarized in about 5 ways, but if you check the SIM size of the existing phone in advance and proceed, you can proceed more easily. If you look at the big frame, you can see that you can buy a self-sufficient phone and use it by inserting only a SIM. No opening required. Since the existing SIM is open, you can see that only the device is changed to the existing number and used. Next, let’s look at the case where you don’t have an existing phone number and want to open it with a self-sufficient phone when you buy a new phone.
If you do not have an existing mobile phone and do not have a phone number, or want to open a service with a sub phone
Buy a self-sufficient phone.
Search and select the carrier you want to use, and proceed with SIM activation.
When you receive a self-sufficient phone, insert a SIM card from an open carrier.
Check if the phone or data can be used normally.
Since there is no information to move, it is used as is.
Similarly, I have summarized it in five points. It’s simple. After purchasing a self-sufficient phone, you can ask the carrier you want to use to open a SIM because you will be using the self-sufficient phone. At this time, you need to choose the SIM size well, but most of the recent self-sufficient phones use nano SIMs, so you can apply for nano SIMs. If you are not sure, you can tell us the model of the self-sufficient phone you will use when proceeding with the opening and ask for it to be opened with a suitable SIM. What should I do if I change the SIM as described above, but cannot use the phone or data normally on my self-sufficient phone? We’ll check it out below.
Self-sufficiency phone confirmation is essential??
If you have worked this far and can use it normally, it is okay to continue using it. However, if you have inserted a USIM into your self-sufficient phone and cannot use the phone or data normally, you can request a confirmed change from the telecommunications company. This symptom occurs occasionally on the iPhone. It is understood that this is due to the closed carrier policy, but most of the symptoms are resolved when the self-sufficient phone is registered with the carrier and a confirmed change is made. In the case of an iPhone that is released as an unlocked phone, it is thought to be a symptom caused by the fact that there are cases where it cannot catch the frequency supported by the Korean telecommunications company. Also, if you plan to purchase insurance through a telecommunications company, you must make a final change. If you only want to sign up for Samsung Care or Apple Care, you do not need to make a final change. It is difficult to see that the self-sufficient phone’s definitive change is essential, and those who experience abnormal symptoms or want to subscribe to telecommunications insurance can use it after confirming the definitive change. Most of you know how to use it more cheaply while using a self-sufficient phone, but in the next post, we will discuss how to use it cheaply through major carriers.
