However, a phone's IMEI may be easy to change with special tools. [10] [better source needed] In addition, IMEI is an un-authenticated mobile identifier (as opposed to IMSI, which is routinely authenticated by home and serving mobile networks.) Using a spoofed IMEI can thwart some efforts to track handsets, or target handsets for lawful intercept.
To avoid confusion the database of GSM Association was renamed to IMEI Database - IMEI DB [1] (it was in 2003-2008, see “Document History” at IMEI Database File Format Specification [2]). Also sometimes a common IMEI database for several EIRs is called SEIR (Shared EIR). In each country, the CEIR can interact with IMEI DB differently.
TIA also allocates IMEI codes, specifically destined for dual-technology phones, out of the RR=99 range. This range is commonly (but not exclusively) used for LTE-capable handsets with CDMA support. Other administrators working under GSMA may also allocate any IMEI for use in dual-technology phones.
The Type Allocation Code (TAC) is the initial eight-digit portion of the 15-digit IMEI and 16-digit IMEISV codes used to uniquely identify wireless devices.. The Type Allocation Code identifies a particular model (and often revision) of wireless telephone for use on a GSM, UMTS, LTE, 5G NR, iDEN, Iridium or other IMEI-employing wireless network.

The most significant changes to the iPhone 6 and iPhone 6 Plus are its displays; both branded as "Retina HD Display" and "ion-strengthened", the iPhone 6 display is 4.7 inches in size with a 16:9 resolution of 1334x750 (326 ppi, minus one row of pixels), while the iPhone 6 Plus includes a 5.5-inch 1920x1080 display (401 PPI). The displays use a ...
For example, an iPhone 6 was designed to be capable of supporting LTE FDD, LTE TD, CDMA, and WCDMA technologies but China Mobile reached a deal with Apple to create a special model for China Mobile in addition to the off-contract retail model sold by Apple and third party vendors with the capability to support LTE FDD, CDMA, WCDMA, which are ...
A telephone reported stolen can have its IMEI blocked by networks, preventing them from being used as mobile devices. [11] iOS offers a similar "Activation Lock" feature via the "Find My iPhone" security software, where a device can be remotely prevented from operating (even after it has been erased), protected by the owner's Apple ID.
