According to Samsung, when you insert a USIM card that you have been using into your newly bought Galaxy S23 smartphone, calls, messages, and data access may be blocked due to the USIM change, and you may receive a text message requesting authentication.
In case you don’t proceed with authentication by yourself using the URL received by the message, the use of data communication will be restricted. For clarification, it’s not an issue or bug from the phone side as it’s a common policy of South Korea Telecom, Korea Telecom, and LG Uplus.
All three network service providers follow Korea Information and Communications Promotion Association information provision consent procedure so that calls, messages, and data access are blocked when changing the USIM to verify the identity of the holder in the dual SIM (USIM and eSIM) model.
If you are having the same problem on your new S23 phone, you are advised to authenticate yourself using the self-authentication URL. What to do if the URL is not received or accidentally deleted? It’s simple, you just need to get in touch with your network provider.
“There may be differences in restricted items and timing for each carrier. If the subscription is opened at a telecommunications agency, the KAIT information provision agreement is included in the subscription form, so this problem does not occur.”
Galaxy models fall in authentication requirement:
- Galaxy S23 series
- Galaxy Z Fold 4
- Galaxy Z Flip 4
- Other eSIM / Dual SIM Galaxy models.
How to verify your identity
- Inquire to the customer center of the telecommunication company you subscribed to
- Contact the call quality department and receive the release URL
- Connect to the network via WI-FI or hotspot
- Access the URL
- Proceed with authentication
Here are examples of URL via text message:
What is USIM?
We all are aware of SIM, whereas the USIM is the functional equivalent of the SIM in a GSM device. It is the entity, which stores subscriber-related info and implements the security functions pertaining to authentication on the user side in UMTS and LTE (3G and 4G) devices.
Apple doesn’t want to enter the Samsung-led foldables market without technological uniqueness. The company has been absent from the rapidly growing foldable segment, which recently welcomed a triple foldable handset from Huawei.
According to Kipost, Apple is seeking its own supply chain of ultra-thin glass technology. The company desires to have its own control over some particular aspects. The move is to differentiate technological innovation from Samsung.
Samsung is expected to supply OLED panels for foldable Apple products. Ultra-thin glass, which is a crucial component in foldable screens, is largely controlled by Samsung D. The reason is the company’s saturation in the international market.
Apple doesn’t reportedly want everything to be done by display manufacturers. If it happens, the company won’t have anything to differentiate its product from rivals. The desire is necessary as Apple is already too late in the market.
Apart from ultra-thin glass, the US tech giant is looking to attain control over supply chain management too. The company is also exploring backplate technology, to ensure critical areas of demonization without any hurry.
UTG is a key material used in foldable displays, which is responsible for flexibility and durability. Backplate in foldable devices often refers to the component that supports the display, which should be durable for long-lasting products.
The report suggests Apple wants uniqueness in two crucial materials—UTG and backplates. This means Samsung Display won’t be able to breathe freely even after being the main foldable panel supplier for Apple’s future foldable devices.
Japan’s KDDI selected Samsung as the main vendor for 5G expansion. Samsung’s vRAN will be deployed by KDDI starting next year for 5G expansion. The company will provide 4G and 5G O-RAN-compliant vRAN solutions in Japan.
Samsung today confirmed selection by KDDI as a key 4G and 5G O-RAN compliant vRAN provider for their Open RAN deployment in Japan. The partnership with KDDI will help Samsung strengthen its role in Japan’s 5G expansion.
“Together with KDDI, we are thrilled to take this significant step and strengthen our presence in Japan,” said Junehee Lee, Executive Vice President, Head of Global Sales & Marketing, Networks Business at Samsung Electronics.
The South Korean tech giant noted that it’s bringing vRAN 3.0 solution, a full suite of O-RAN compliant radios supporting low- and mid-bands including advanced Massive MIMO radios and third-party radio integration support.
Kazuyuki Yoshimura, Chief Technology Officer of KDDI: “Today’s announcement represents KDDI’s dedication to bringing innovative technologies to Japan. We are proud to deliver a cutting-edge and reliable radio access network.”
Key features of Samsung CognitiV Networks Operations Suite (NOS) will also be offered. The features streamline the onboarding, deployment, and operation processes, enabling KDDI to transform its widespread network efficiently.
Beyond that Samsung and KDDI will expand the reach of Open RAN in the coming years. For now, KDDI’s Open RAN network will feature enhanced capabilities for improved energy efficiency, optimized performance, and intelligent automation.
Samsung Wallet getting an instant Tap to Transfer feature for Galaxy users. The latest addition unlocks instant and seamless money transfer. This move reiterates Samsung’s commitment to upscaling the Galaxy ecosystem.
The Tap to Transfer feature allows users of Samsung Wallet on Galaxy phones to instantly transfer money by tapping the backs of their devices together. The transfer process is powered by NFC technology embedded in Galaxy phones.
Samsung confirmed that the feature will be gradually supported through app updates in Samsung Wallet. The Tap to Transfer feature eliminates the need to ask for or input the recipient’s account number during transfers.
This seamless process will help Galaxy users save time and effort as well as reduce the risk of sending money to the wrong account. It’s an answer to Apple iOS 18’s Tap to Cash feature, which allows users to transfer funds with nearby ecosystem devices.
Samsung Wallet allows the recipient to set a representative account for receiving funds and can receive ‘Tap to Transfer’ payments even when their Galaxy’s screen is off – even without opening the Samsung Wallet app.
Here’s how it works:
The user who wants to send money enters the password for their registered account in Samsung Wallet, inputs the transfer amount, then taps their phone against the recipient’s phone and completes the transfer through the default unlock method.
The recipient’s account number transmitted during the ‘Tap to Transfer’ process is encrypted and sent to the sender. Instead of displaying the full account number, only the last four digits of the recipient’s mobile phone number are shown.
The feature is currently available in South Korea and supported by Woori Bank.
