Exploring the Latest DSFA Dual SIM Full Active Mobile Devices in 2018
The year 2018 saw a significant advancement in mobile device technology with the introduction of dual SIM Full Active (DSFA) technology. This technology allows users to make and receive calls on both SIM cards simultaneously, providing unparalleled flexibility and convenience. Below, we explore the flagship devices that adapted this innovative feature.
Notable DSFA Devices in 2018
Several top-tier smartphones were released in 2018 with DSFA capabilities, enabling seamless usage of both SIM cards. Here are some of the prominent models:
1. Huawei Mate 20 Pro
Lazully launched in October 2018, the Huawei Mate 20 Pro was a flagship device that featured a dual SIM option with DSFA technology. This allowed users to use both SIM cards simultaneously, making it highly versatile and user-friendly.
2. Xiaomi Mi MIX 3
The Xiaomi Mi MIX 3, released in November 2018, was another remarkable mobile device that included dual SIM support with full active functionality. This device provided users with the ability to manage calls and SMS on both SIM cards concurrently.
3. ASUS Zenfone 5Z
Earlier in 2018, the ASUS Zenfone 5Z also supported dual SIM functionality with full active capabilities. This means that users could utilize both SIM cards at the same time, ensuring optimal flexibility and convenience.
4. Oppo R17 Pro
Released in late 2018, the Oppo R17 Pro offered dual SIM full active support, enhancing the user experience by allowing simultaneous use of both SIM cards.
Understanding Dual SIM Full Active (DSFA)
DSFA, or Dual SIM Full Active, is a feature that enables users to have two independent transceivers in their mobile phone. This technology allows for simultaneous calls on both SIM cards without requiring the swapping of sim-cards or the use of call waiting features, which are typical in older feature phones.
DSFA vs Dual Standby
In the context of new mobile devices, dual standby refers to the ability to use both SIM cards in a single phone, but not necessarily at the same time. However, with the DSFA technology, both SIM cards can operate independently, offering much more flexibility and functionality.
Older Models with DSFA
Users may be interested to know that many older Huawei models also benefited from this technology. The Huawei Mate 8, Mate 10, Mate 10 Pro, Mate 20, and Mate S are all known to support DSFA. Similarly, the Huawei P20 might also have this feature, though details about its specific capabilities are limited.
Other Brands with DSFA
Other brands also introduced DSFA in their 2018 models. ASUS's Zenfone 2, for instance, is known to support this technology. Additionally, some Realme models, particularly the Realme 2, offer VoLTE support, though its exact availability and functionality are not specified.
It's important to note that the specific implementation of DSFA can vary across different brands and models. Users looking for dual SIM full active functionality should check the official specifications or customer reviews for the latest and specific capabilities of each device.
Conclusion
2018 was a pivotal year for dual SIM technology, with numerous flagship devices introducing DSFA capabilities. These features have significantly enhanced the user experience, offering more flexibility and convenience in managing both SIM cards simultaneously. Whether you are a business user or a consumer looking for advanced mobile technology, these devices provide a robust solution.
