Questions tagged [dual-sim]

A Dual SIM mobile phone is one which holds two SIM cards. Initially, dual-SIM adapters were made available to use in regular mobile phones to allow them to contain two SIMs, and to switch from one to the other as required. This combination is called a standby dual-SIM phone.

Dual-SIM operation allows the use of two services without the need to carry two phones at the same time.

Types

  • Pseudo-Dual - for convenience to use second SIM (as rule, it has «no major» slot for this) without both SIMs connected with owner's mobile service providers (MSP).
  • Dual Sim Shift
  • Dual Sim Stand-by (DSS) - allows the device to switch from one network to the other when required
  • Dual Sim Active (DSA) - allows the device to be connected to both networks at the same time (it's using transceiver). You can switch between the calls without dropping one (select Samsung models)

  • Dual talk - possibility to talk with 2 callers from different MSPs at same time (LG GX500)
