Apple has sold over 200,000 iPhone 7 units in South Korea as of Monday, four days after starting sales there on October 21.
The phones will likely sell over 300,000 units by the end of the month, officials from local telcos SK Telecom and KT have said.
Pre-orders for Apple's latest hit 300,000 since they began on October 14.
Sales figures for the iPhone 7 are similar to that of the Galaxy Note 7 when it launched in August. The local smartphone market since stagnated in September due to a lack of new phones and the ending of the Galaxy Note 7.
Samsung is now upping marketing for Galaxy S7 and S7 Edge, which launched earlier this year.
The South Korean tech giant is preparing a new exchange program for the Galaxy Note 7 that will likely offer S7s for the time being, before offering the upcoming S8 on its release.
Fellow Korean company LG began selling the V20 last month. The company sold around 3,000 units per day since launching, but this jumped to 7,000 since ending of the Note 7 was announced, telco officials say.
