Many of those who purchase a self-sufficient phone must be worried about how to open it. When I bought a self-sufficient phone to save communication costs, I was worried about opening it, so I remember doing a lot of searching on the Internet. In fact, it is not difficult to open a self-sufficient phone, but since it is usually self-opening, it seems that many people feel burdened in that they have to open it themselves. So today, I would like to tell you how to open a self-sufficient phone easily and simply. And when self-opening, I will introduce you to the points you need to be careful of.
How to open a self-sufficient phone 자급제폰 개통방법
1. Buy a self-sufficient phone
In order to open a self-sufficient phone, you must first prepare a self-sufficient phone. Self-sufficient phones can be purchased at online shopping malls such as Coupang, large discount stores, telecommunications agencies, and telecommunications companies’ websites. 좋은뉴스
2. Choose a carrier and rate plan
Most of the reasons for purchasing a self-sufficient phone are that you can freely choose a carrier and rate plan. If you have purchased a self-sufficient phone, please select the carrier and rate plan you will use. You can choose a large carrier (KT, SKT, LG U+) or a budget phone carrier. Usually, when you purchase a self-sufficient phone, you often use a plan from a low-cost phone carrier to save communication costs. In the case of affordable phone plans, there are many promotions for publicity, so if you look carefully, you can use unlimited plans for 20,000 to 30,000 won.
Since using a self-sufficient phone has the advantage of not having a contract, there are many people who save communication costs by changing the plan every time a budget phone plan is promoted. 5G plans have also been released as the types of low-priced phone plans are diversifying, but those who need data sharing, such as smart watches, should check whether the plan they want to use supports data sharing.
3. Buy USIM
You do not need to purchase a SIM if you are using the SIM as it was in your existing cell phone, but if you plan to change your carrier or rate plan, you must purchase a SIM separately.
SIM can be purchased both online and offline. In my case, I purchased a SIM from the homepage of a budget phone carrier and the price was 8800 won. You can purchase a SIM card at cell phone stores, Daiso, convenience stores, and large marts, so you can purchase it wherever you want. If you purchase from a cell phone dealer, you have the advantage of being able to purchase and open a SIM card at once, but usually, you can get a little more discount on your rate plan by opening it yourself.
4. Opening and SIM registration
If you have purchased a SIM, now is the time to open it. The point to note here is that you must open the purchased SIM before attaching it to the self-sufficient phone. If you apply for opening after attaching a SIM to a self-sufficient phone, an error may occur.
If you go to the homepage of the telecommunications company you want to use, there is an application menu. When you buy a SIM card, a PIN number comes with it. If you enter this pin number, you can apply for opening. In the case of number portability, it is not possible to open on Sunday, but in the case of new opening, it is possible to open on Sunday. After opening, you can attach the SIM to the self-sufficient phone.
You may think that applying for opening in this way is a disadvantage of a self-sufficient phone. If self-opening is not bothersome, you can go to the dealership and ask for opening, or you can call 114 and apply for opening.
If you want to use an existing SIM for a self-sufficient phone, you do not need to apply for a separate opening, and if you attach an existing SIM to the self-sufficient phone, it will be opened immediately. If you do this and you do not receive a message saying that the device has been opened, you can turn on the airplane mode and then turn it off.
