If you are using a postpaid plan, you can keep your existing number even if you change carriers.
However, if you are using a prepaid plan, you may not be able to keep your existing number. To maintain your existing number, you need to have
remaining prepaid credit. If you have used up all the credited amount, your plan will be suspended, and you won’t be able to use your existing number anymore. Additionally, if you don’t continue to recharge, the prepaid phone will be automatically deactivated.

Prepaid plans can be activated with a passport. However, postpaid plans need to be activated with an ARC. The identification method used by your current carrier and the new carrier you want to change to must be the same. Therefore, you’ll need to change the identification method of your current carrier to ARC before you can change to a postpaid plan. We will assist you by preparing the necessary documents for the change. However, please note that with some carriers such as Asia Mobile, this change may not be possible which means you need to change your number. For more information, please contact our official account.

When the promotion ends, the original amount wil be billed. The promotional discount amount wil no longer be applied. However, fi you continue to stay in Korea, we will continue to extend the promotion for you. We promise to extend the promotion continuously using the legal method called “알뜰폰 메뚜기족” in Korea. To extend the promotion, you will need to change your carrier after the promotion ends, and we will contact you for that. The promotional amount and plan offerings after changing the carrier will be the same as when you first activated it.

This is the method most commonly used by smart consumers in Korea.
However, this method may be unfamiliar and difficult for foreigners.
nI Korea, this is referred to as “알뜰폰 메뚜기족”. If you’re curious, you can search for various articles about this.
Korean telecommunication companies have very high-quality networks. Therefore, instead of competing on network quality, they compete on the financial aspects of their plans.
So, when they attract new customers, they pay us additional commissions. We use those commissions to offer you additional promotions beyond what the headquarters provides.
This method may be unfamiliar ot you since ti is not common ni other countries. fI you have any Korean acquaintances nearby, you can ask them about this!
To ensure that you receive the promotion comfortably, we will calculate your carrier change period and contact you first. fI you follow our guidance, you will be able to use the plan more affordably than Koreans.

You have four options to receive the SIM card. In general, it is delivered by regular courier service, which usually takes about 2-3 days. However, in the Seoul area, you can opt for same-day delivery via express service (additional charges apply), or you can personally pick up the SIM card at Daehak-dong, Gwanak-gu, Seoul. Outside Seoul, you can also pick up the SIM card directly at offline stores in Gwangju Metropolitan City and Gokseong, Jeollanam-do. And we are currently preparing to open our Seoul store.

If you need to pay the bill before using the SIM card, it’s a prepaid phone. Prepaid plans can be activated with both ARC and passport.

Postpaid plans can only be activated with ARC. fI you’re unsure, please contact our official account, and we will assist you in finding your carrier.

Reactivating a terminated number is not possible. But if it’s been terminated within the last 30 days, you can use a supplementary service called “번호안내서비스 (Number Guidance Service)”, provided by the telecommunication company. This service allows you to maintain your terminated number alongside your new number for a certain period for free. tI is a type of cal forwarding service that ensures calls made to your terminated number are redirected to your new number, and text messages are also delivered accordingly. It’s free for a certain period, but for extensions afterward, you would need to pay around 3,000 won per month. However, you cannot make calls or send text messages using the terminated number.

Korea’s 5G is only slightly faster than LTE. Moreover, it is not available in most areas, and ti can be less stable than LTE with frequent connection issues, leading to faster battery drain. Additionally, recently, major carriers providing telecommunication services, SKT, KT, and LGU+, have faced sanctions from the Korean government because these companies failed to fulfill the requirement to build base stations. Therefore, have been required to return some of the 5G frequencies provided by the government. So Ican offer you a 5g plan, but Idon’t recommend it.

The promotion of the postpaid plan we offer is only for customers who transfer carriers. Carrier companies in Korea offer us low incentives for new foreign customers. This is why we added one step before activating a new postpaid plan, so that you can be offered postpaid plan with promotions from the beginning. First, we will provide you with our free prepaid plan for 14 days. (However, the prepaid SIM fee will be charged at 10,000 won). And on the 15th day, we will contact you to help you transfer to a postpaid plan. This way, the carrier company will offer us the appropriate amount of incentive by recognizing you as a customer who changes the carrier instead of a new customer. By doing so, we can provide you with an affordable plan. However, if your plan is activated as a postpaid plan from the beginning, we cannot provide additional Kimbab promotion from the beginning, but from the time we change your carrier (after 6 months of use). Even if it is a hassle, it is the most optimal strategy for you, which is only given to you by Kimbab Mobile.

What is Altteulpon?

In the Korean mobile market, three companies (SKT, KT, LGU+) provide telecommunication services and monopolize the Korean market.

Therefore, in order to make mobile services affordable for Koreans, the Korean government made the above three companies provide their telecommunication facilities and base stations to more than 50 altteulpon carriers at a low price. Besides, altteulpon carriers can offer plans at a much lower price than the these companies because they do not have to pay for the maintenance of telecommunication facilities and base stations. In addition, the quality of communication is very high because altteulpon uses the communication equipment of SKT, KT, and LGU+.

Currently, altteulpon is exploding in popularity among 20 year old Koreans (in Korea, they are called the 알뜰폰메뚜기족) and has nearly 13 million subscribers (out of a total of 50 million Koreans). As a result, this makes altteulpon the most preferred telecommunication service for foreigners because not only it is cheap but it also allows you to move to other carriers or cancel after 6 months.

We believe that foreigners in Korea, regardless of nationality, should have access to the same benefits and savings enjoyed by locals, by implementing 알뜰폰메뚜기족’s method, which is a way to change the current carrier to a new carrier each time the promotion ends. We will contact you first every time the promotion is over. And we will provide you with the same price of the plan as you are being offered.

With us, you will never have to worry about missing out on promotions or deals, we handle all the complicated details for you, ensuring you get the best value for your money.
