Firefox OS: Dual SIM support is from the new version 1.3 is possible (Source:

Now pull After Android increasingly mobile operating systems in terms of dual SIM support after. Not only the recently released version of Windows Phone 8.1 comes with 2 SIM cards in the same phone deal, but now Firefox OS. The latest version of the operating system offers the possibility to use 2 SIM cards in the same phone. The corresponding interface (API WebIccManager) Namely updated. Mozilla, the provider of Firefox had in 2014 announced this change at MWC in Barcelona and implemented in late May with 1.3 relase into action.

No Firefox dual SIM phones

Although Firefox OS 1.3 can manage 2 SIM slots, however, the function is not yet in theory: A Firefox OS Dual SIM phone there are not so far. Thus, this development is different from that of Windows Phone, where shortly after release of version 8.1 with the Nokia Lumia 630 Dual (test)a terminal with dual-SIM slot has come on the market.

Firefox OS: A different operating system

the mobile operating system developed by the Mozilla organization that it relies on the technology of the Web browser of the same name. The goal of the organization is not to achieve with Firefox OS commercial gain: Rather, only cheap smartphones should be made possible, so that those who are "mobile", which had been without a smartphone for cost reasons. A short presentation of the system with the new releases published in May 2014. Version 1.3 is the official Mozilla Video:

Sensible decision

Especially in emerging countries lacking large parts of the population the money for smart phones, as they are popular in this country. Cheap entry-level models that do not rely on a luxury but essential functions are needed there safely. And just in such countries is often not optimally developed on the mobile network and a second SIM card of another network provider therefore often useful. The decision to support a second SIM slot, thus not only makes sense, because in Europe the demand for dual SIM phones is increasing - but also because it has long been very high in many other countries.

When first dual-SIM models come?

Currently there is not yet Firefox dual SIM phone announced. After all, there are of Alcatel One Touch and ZTE already Firefox smartphones - and since both manufacturers also carry cell phones for 2 SIM cards at the moment it is hopefully only a matter of time until the first devices come to market. However, the currently available phones with the Mozilla OS mostly only abroad are available. Therefore, it can be expected that new (dual-SIM) devices may also initially or officially available only in other markets.
