# Access Point Name Access Point Name is a protocol, standard, or security technology recorded in [[Scanned_20260730-1706|Scanned_20260730-1706]]. In the reconstruction, An APN tells a mobile device which carrier packet-data gateway and service profile to use; wrong APN data can leave voice service intact while breaking mobile data or MMS (T-Mobile APN explanation). ## Historical and Technical Context An [[Access Point Name|APN]] tells a mobile device which carrier packet-data gateway and service profile to use; wrong APN data can leave voice service intact while breaking mobile data or MMS ([T-Mobile APN explanation](https://www.t-mobile.com/dialed-in/wireless/what-is-an-apn)). [[Mobile Country Code|MCC]] 310 identifies the United States, while [[Mobile Network Code|MNC]] 260 identifies T-Mobile's network. “default,” “supl,” “mms,” and “ia” are Android APN service types for general packet data, assisted-location services, multimedia messaging, and initial attachment. The handwritten “wholesale” profile and `mmsmvno.com` endpoint fit an MVNO operating through T-Mobile infrastructure. ## Role in Scanned_20260730-1706 The page documents manual Android provisioning during a number transfer or device migration. It is a practical continuation of page 4: account activation alone did not finish the job, so the network route, MMS endpoint, protocol family, and carrier identifiers were preserved. ## Notebook Evidence - [[Scanned_20260730-1706|Scanned_20260730-1706]], PDF page 5: Mint/T-Mobile APN and MMS configuration. **Evidentiary status:** The page occurrence and transcription are notebook evidence. Technical identification follows the source reconstruction’s cited research. Co-occurrence does not by itself prove ownership, deployment, or a direct operational relationship. ## Relationships and Overlays On the cited page or pages, Access Point Name appears with [[Mobile Country Code|MCC]], [[Mobile Network Code|MNC]]. These are page-level or reconstruction-level relationships, not automatic claims of dependency. ## Cross-Notebook Significance This note parallels the enterprise enrollment and Algorand key-custody material in [[Scanned_20260730-1802|Scanned_20260730-1802]]. Both notebooks separate reachability or network participation from the authority required to change protected state. ## Missed Signals and Open Leads “wapenc” may be an APN-field value or a fragment from the adjacent configuration screen. “75202” and “90210” look like ZIP codes, but their exact relationship to the account is not visible. ## Sources - [[Scanned_20260730-1706|Scanned_20260730-1706]], especially PDF page(s) 5. - `Scanned_20260730-1706.pdf`, cited as a plain archival filename; the PDF is not linked from `wiki-notes`. - External research citations used for identification remain preserved in the source reconstruction. - [T-Mobile APN explanation](https://www.t-mobile.com/dialed-in/wireless/what-is-an-apn)
