As with any technology, its evolution is ongoing, and the industry will continue to adapt to the changing needs of the global mobile user base. Both SIM cards can be active simultaneously, meaning you can receive calls or texts on one while using data or making a call on the other. The difference between the two types of dual SIM phones.

At first glance, it would seem that having two transceivers does not influence this capability at all: "Internally, the active dual-SIM phones will have two transceivers, to allow simultaneous reception of signal from different connections.", as from here. According to this, this feature is only connected with the number of CPUs. I still wonder which is the relation between the number of CPUs and transceivers, and what Dual Standby really means in this context. I added link (external) for list of Dual SIM phones under article, but someone marked it as spam. So a question is: why not? I think it's good know which phones know it. Maybe someone who come, want to know it. The ZTE V889D apparently supports something called Dual-SIM W+G / G+G, as seen here http://www.etowalk.com/zte-v889d-3g-wcdma-40wvga-dual-sim-android-v23-msm7227a_p2875.html (see Network). What exactly does W+G / G+G stand for? Google is of no help at all. I'd be glad if anyone here's up to expounding on the article, most especially with its history and the various types of multi-SIM handsets. Blake Gripling (talk) 05:18, 27 April 2014 (UTC)[reply] I've modified the examples. As an owner of both a Samsung Galaxy S Duos and an HTC 600, I can say for certain that one is a standby and one is an active dual sim phone. The article mentions "standby" and redirects from "Dual Standby" but there is no explanation of what "standby" means. —Preceding unsigned comment added by 60.241.81.166 (talk) 01:49, 23 December 2008 (UTC)[reply] I rewrote the article to make it more structured and easier to understand, but I am not an expert myself. I based the definition of "standby" on this post, but that's obviously not a reliable source. Moreover, the Spanish Wikipedia refers to "Dual SIM One Stand-by" (for non-simultaneous models) and "Dual SIM Stand-by" (for simultaneous models), which is almost contradictory to the definitions used here.

Dual SIM Dual Standby (DSDS) phones allow both SIMs to be accessed by using time multiplexing. When one SIM is in active use, for example on a call, the modem locks to it, leaving the other SIM unavailable. Older examples of dual-SIM standby phones include the Samsung Galaxy S Duos, the Sony Xperia M2 Dual, and the iPhone XS, XS Max and iPhone XR. Some sub-contract Chinese companies supply inexpensive dual SIM handsets, mainly in Asian countries. The phones, which also usually include touch screen interfaces and other modern features, typically retail for a much lower price than branded models. While some such phones are sold under generic names or are rebadged by smaller companies under their own brand, numerous manufacturers, especially in China, produce phones, including dual SIM models, under counterfeit trademarks such as those of Nokia or Samsung, either as cosmetically-identical clones of the originals, or in completely different designs, with the logo of a notable manufacturer present in order to take advantage of brand recognition or brand image.
