So from here, I figured out what was causing the connectivity issues in the Uplus cellular network. This work was so easy because the extracted files itself have a semantic path such as 'IMS', 'Profile', and 'Mandatory'. There was a lot of information by those people needing VoLTE support, I've got many pieces of information from there, and by inspecting Qualcomm MBN(Modem Configuration Binaries) files I managed to know what configurations are in there and how configurations are applied to the device modem. Me too of course I have suffered the same issues, going into this, I'd like to learn how cellular network works and Qualcomm modems handle the signal and then deal with these issues.įortunately there was a community dealing with this issues in South Korea: 리퍼비쉬팩토리(RefurbishFacotry). Fortunately, by utilizing IMS-based technologies like SMS over IP and VoLTE(Voice over LTE), Uplus was able to support a lot of smartphones including iPhones.īut the problem has not been solved yet for the smartphones imported, even though these days more and more smartphones are supporting almost all the whole LTE bands, those smartphones can use LTE capabilities but have some problems like many users are suffering frequently dropping calls, and losing signals. The other carriers like SKT and KT officially support WCDMA and HSPA for a circuit-switched fallback (CSFB), but Uplus DOES NOT have support for them, these were the reason behind lack of support of iPhones before 5 in the Uplus carrier. In general, the experience was positive but there was a critical issue with 4G compatibility: Most of the smartphones which are imported do not officially support LG Uplus network in South Korea because The LTE bands Uplus uses are B1(2100), B5(850 for main), B7(2600), which are not commonly used in global, and Uplus in Korea does not have commonly used 3G service network such as WCDMA and HSPA. If you have any questions related to this guide, then feel free to use the comment section below.For the past week, I've been using OnePlus 8 Pro and there's a fair bit to talk about with using it in South Korea.
