In 2G networks, the SIM card and SIM application were bound together, so that "SIM card" could mean the physical card, or any physical card with the SIM application. In a GSM network, the UICC contains a SIM application and in a UMTS network, it contains a USIM application. A UICC may contain several applications, making it possible for the ...
4G eLTE is Huawei's proprietary derivative of the LTE standard, the "e" standing for "enhanced", intended to provide wireless broadband transmission with peak downlink speeds of 50 Mbit/s and 20 Mbit/s uplink per site in 5 MHz, 10 MHz and 15 MHz frequencies.
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.
Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming in ITU Regions 1, 3 and partially Region 2 (e.g. Costa Rica, Venezuela, Brazil and some Caribbean countries or territories. Networks on LTE band 20 (LTE-FDD) are suitable for roaming in ITU Region 1 only. Networks on LTE band 5 (LTE-FDD) are suitable for roaming in ITU Regions 2 and 3.

A SIM box (also called a SIM bank) is device used as part of a VoIP gateway installation. It contains a number of SIM cards, which are linked to the gateway but housed and stored separately from it. A SIM box can have SIM cards of different mobile operators installed, permitting it to operate with several GSM gateways located in different places.
