How to change the APN settings on the Samsung Galaxy S5 (SPRINT) and make it work internationally:

UICC SIM cards, are simply there to give you access to LTE, nothing more, nothing less. They have a 'personalized code' that is linked to your device, and will ONLY work on that device. You CAN NOT take the SIM card, and put it into another device, even if its the same exact model, and expect it to work. In 'About Device' go to the next menu and choose 'System Updates' option and then 'Check for Updates'. Your phone will update automatically. You can update your device through Wi-Fi network only because your new SIM has no connectivity at all. Be Sure that You Are Unlocking GSM Phone. It is impossible to unlock Samsung Galaxy running on CDMA. In the update settings on your samsung, click on UICC Unlock and if you have Sprint (or Boost Mobile) it should fail. For some reason, after the UICC Unlock fails you can retry the OMADM profile update in your notifications and it'll work correctly. I was in the same situation as David King so I hope he tries this too. If no, then Download Data then click Get root. 1)insert Sim 2)install GTv3.1.5.apk 3)install GTUpdate2v3.1.8.apk and run, SuperSU will ask the question, then Grant, then Update and reboot your smartphone after the program closes itself. 4)Run idone press.UICC SIM Unlock. 5)reboot your device go to Settings menu, Mobile networks, Network mode, select GSM/UMTS.

1. Request Sprint iDCS to do a UICC unlock for the device.

System Update enables IT administrators to distribute updates for software, drivers, and BIOS in a managed environment from a local server. In system updates there isoption unlock uicc. Lowpriceskates Asked: 07:45. Domainscot 07:45. Settings - System updates shows: UICC Unlock 'Your device is locked to Sprint SIMs only'. Tried AT&T and T-Mobile GSM SIM cards, both are shown as invalid SIM cards. The whole menu 'Network Mode' is not present in Settings. Used 'GCF Setting' to make sure, that GSM with all bands is set. This is the case, CDMA and LTE bands are disabled. Uicc Unlock Code Android Robot From System Updates I met all the FCC requirements and Sprint level 1, 2 and 3 tier support have already said the phone is now unlocked via MEID AND IMEI.

2. Once confirmation is received from iDCS go to your phone's settings.

3. Settings -> General -> System Update -> UICC Unlock

4. Press UICC Unlock

5. If successful it should say the profile has been updated.

Update Uicc Unlock

6. Power off the device

7. Remove the Sprint SIM card and insert Foreign SIM card.

8.Power on the device and go to phone's settings.

9 Settings -> Connections -> More networks -> Mobile networks -> Network mode; now change the LTE/CDMA to GSM/UMTS (should automatically restart the device)

10. Once the device is back on; Settings -> Connections -> More networks -> Mobile networks -> Network operators; click on the + symbol on the top right corner now you can add a custom APN for your foreign network.

Overview

This topic specifies an extension to the Mobile Broadband Interface Model (MBIM) interface to permit accessing UICC smart card application and file systems. This extension to MBIM exposes logical access to the UICC's ETSI TS 102 221 technical specification-compliant applications and filesystems, and is supported in Windows 10, version 1903 and later.

UICC access and security

The UICC provides a file system and supports a set of applications that can run concurrently. These include the USIM for UMTS, CSIM for CDMA, and ISIM for IMS. The SIM is a legacy portion of the UICC that can be modeled as one of these applications (for GSM).

The following diagram from Section 8.1 of the ETSI TS 102 221 technical specification shows an example card application structure.

The UICC file system can be regarded as a forest of directory trees. The legacy SIM tree is rooted at a Master File (MF) and contains up to two levels of subdirectories (Dedicated Files, or DFs) containing Elemental Files (EFs) that hold various types of information. The SIM defines DFs under the MF, one of which, DFTelecom, contains information common to multiple access types such as the common phone book. Additional applications are effectively implemented as separate trees, each rooted in its own Application Directory File (ADF). Each ADF is identified by an application identifier that can be up to 128 bits long. A file under the card root (EFDir under the MF in the diagram) contains the application names and corresponding identifiers. Within a tree (the MF or an ADF), DFs and EFs might be identified by a path of file IDs, where a file ID is a 16-bit integer.

NDIS interface extensions

The following OIDs have been defined to support UICC application and file system access.

MBIM_CID_MS_UICC_APP_LIST

This CID retrieves a list of applications in a UICC and information about them. When the UICC in the modem is fully initialized and ready to register with the mobile operator, a UICC application must be selected for registration and a query with this CID should return the selected application in the ActiveAppIndex field in the MBIM_UICC_APP_LIST structure used in response.

MBIM_CID_MS_PIN_EX

This CID is used to perform all PIN security operations as defined in Section 9 of the ETSI TS 102 221 technical specification. The CID is similar to MBIM_CID_MS_PIN, but extends it to support multi-app UICC cards. Only single-verification-capable UICCs are supported. Multi-verification-capable UICCs that support more than one application PIN are not supported. One application PIN (PIN1) is assigned to all ADFs/DFs and files on the UICC. However, each application can specify a local PIN (PIN2) as a level 2 user verification requirement, resulting in the need for additional validation for every access command. This scenario is what MBIM_CID_MS_PIN_EX supports.

Just like MBIM_CID_MS_PIN, with MBIM_CID_MS_PIN_EX the device only reports one PIN at a time. If multiple PINs are enabled and reporting multiple PINs is also enabled, then functions must report PIN1 first. For example, if subsidy lock reporting is enabled and the SIM's PIN1 is enabled, then the subsidy lock PIN should be reported in a subsequent query request only after PIN1 has been successfully verified. An empty PIN is permitted together with MBIMPinOperationEnter. An empty PIN is specified by setting the PinSize to zero. In this case, a SET command is similar to a QUERY and returns the state of the PIN referenced. This is fully aligned to the behavior of the VERIFY command as specified in Section 11.1.9 of the ETSI TS 102 221 technical specification.
