    Dual-SIM phones have long been an integral part of the daily experience of most mobile users, and they can be used to manage personal and business calls or access plans and incentives offered by different operators in a single phone. The second SIM card slot also offers an easy option to insert a new SIM card while traveling, so you do not need to remove the original SIM card. This technology has entered a new phase with the presence of 5G network and dual 5G SIM phones are gradually becoming available. The manufacturers' approach to 5G dual SIM cards is different, but we will get acquainted with them in the following.

    با The fact that there are many dual-SIM phones with 5G capability in the market and now they are not limited to the top of the market in terms of price, but all of them are not the same in terms of features of two 5G SIM cards and some offer a significant advantage in this regard. Fifth generation dual-SIM or Dual-SIM 5G capability As you can guess, it refers to the possibility of both SIM cards accessing the 5G network on one phone; Where the same or different 5G network (depending on the operator) can be accessed on each SIM card without the need to move the SIM cards. This situation, however, is not available for all models, and for some of them (which happen to be among the most important phones in this category), the 5G network is offered only on the main SIM card. In this case, the second SIM card has the maximum capability to work in the 4G network, and its physical displacement is not able to work with the fifth generation signals.

    5G + 5G support on both SIM cards As you can guess, it depends directly on the device's processing chipset and communication modem, where one name has shone brighter over the last one or two years. Taiwanese company MediaTek, which has been competing closely with Qualcomm over the past year or two with low-cost Dimensity chipsets, has supported the feature from the outset with the introduction of the Dimensity 1000 and its Plus version, despite the next two mid-range models, the Dimensity 720 and Dimensity 800 was not known about this option, but again in Dimensity 700 and Dimensity 800U this option was added to the list of features of the device chipset.

    با Bypassing MediaTek, Qualcomm's place on this list seems too empty, and the company, contrary to expectations, still does not support the dual 5G SIM card feature in its mobile chipsets; The reason or at least Qualcomm's reason for the absence can be found in the speech of Alex Katouzian, Qualcomm's senior vice president and head of mobile, who in an interview with the Android Authority website in late 2020 used Qualcomm's plan to introduce the 5G + 5G dual SIM card feature. Has spoken to VoNR in the future; According to Katozian, the introduction of the dual 5G + 5G SIM card feature requires the option of 5G (or VoNR) voice transmission, which in itself will require the establishment of a standalone 5G (or SA 5G) network in the absence of a standalone network, while The current 5G is often based on older 4G networks. You can't talk about a real 5G dual SIM phone. In simpler terms, according to the Qualcomm CEO, current 5G dual-SIM phones provide their data from the 5G network, and the 5G logo is embedded next to the antenna lines of both SIM cards, but when it comes to voice transmission and Phone calls (due to the non-independent nature or NSA of this structure) have no choice but to return to the 4G network and what is called VoLTE. In future networks, as Qualcomm envisions, not only data but also voice will be transmitted over the 5G platform, thus speaking of the birth of a true 5G dual-SIM phone.

    MediaTek is not far behind Qualcomm, at least in theory, and has been talking about VoNR support as soon as the fifth generation standalone network (SA 5G) is ready on the company's chipsets. In this case, although the call and voice transfer option in MediaTek Dual-SIM 5G phones is established via 4G LTE network, it goes without saying that this issue does not have much effect on the choice of users in this category and naturally simultaneous access to two 5G networks is very important. Higher than the type of sound transmission during a call.

    The problem, however, does not end there, and MediaTek's decision to introduce the new Dimenaity 1200 chipset as "the first 5G chip with the ability to provide two true 5G SIM cards (5G SA + 5G SA)" begs the question. It turns out that the company's previous chipsets were apparently barred from offering two real 5G SIM cards in some way, and Qualcomm's claim in this regard was closer to reality.

    Huawei and Samsung, two other manufacturers of 5G chipsets, have so far declined to comment directly.

    Despite the relatively large number of MediaTek 5G dual-SIM handsets, these handsets usually do not have much presence in the international market and to date are often only available in the Chinese and Indian markets. Qualcomm's approach to Dual-SIM 5G marks the imminent introduction of this feature in a wider range of mobile phones; Increasing the number of independent 5G networks will play an effective role in its acquisition.
