Dual-VoLTE SOCs

List of Dual-VoLTE SOCs Dual 4G Active Standby Phone Specs Compare

Why do you need Dual-VoLTE SOCs? It is because the world is moving towards 4G only networks with 5G round the corner. This will mean if you have a dual SIM phone, and want to make use of the network data connectivity on both the SIM cards simultaneously, the best options to go with is a phone supporting Dual SIM Dual VoLTE (DSDV) functionality. More than the phone itself, you will need to give a thought to the processors or SoCs that support the DSDV option.

We will check out the options that offer support for such functionality. Besides, we will also attempt in understanding what Dual VoLTE is and how effective it can be.

What is Dual SIM Dual VoLTE?

As can be understood based on the name itself, the dual SIM dual VoLTE is the functionality where you will be able to experience the 4G VoLTE connectivity on both your SIM cards simultaneously.

This can be explained with an example. Assume you have two 4G SIM cards where one of them offer a 4G only service. In such a case, when you switch to the data network on the non-4G only SIM, the network on the 4G only SIM vanishes. Ideally, most of the phones support 4G connections on any one of the two SIM cards, and not on the two cards simultaneously.

This is where Dual SIM Dual VoLTE tends to be of practical use. If you have a phone that supports the technology, you will find that you will be able to use the 4G connectivity on both the SIM cards. This will mean that even when you switch to any one of the data networks, you will continue to get the VoLTE services on the other SIM even without the Internet.

Also, it is worth noting the fact that the Dual VoLTE technology provides an enhanced level of HD call clarity.

Are there Any phones that support the Dual VoLTE feature?

The trend of offering the dual VoLTE connectivity has been in vogue only recently. This requirement was required after the launch of 4G only services by telecom operators. A good example is Reliance Jio in India which is a 4G only network and does not offer any 3G or 2G connectivity.

Some of the modern breeds of phones that have begun launching the Dual VoLTE functionality can be summed up as Honor View 10, Zenfone Max Pro M1 / M2, Oppo F7, and Realme 1 to name a few. Please note that the dual VoLTE is a functionality that the SoC or the processor inside your phone should support.

Moreover, just because the SoC supports the functionality should not necessarily mean that the feature will be made available on a phone that uses the particular chipset. The OEM may go against the plan and choose not to provide the functionality on its devices. But, on the good news is that the feature can be enabled by merely a software update.

Which Dual-VoLTE SOCs support Dual SIM Dual 4G VoLTE?

The recently launched chipsets support the functionality. The SoCs were launched in 2019 and later are expected to come with the functionality to support the Dual SIM Dual VoLTE feature. Here is the list of the SoCs that support the dual VoLTE feature.

The Concluding Thoughts

That is all we have as of now concerning the dual VoLTE feature and the SoCs that support the technology. Do note that just because the processor support the functionality to offer you dual VoLTE feature, it might not necessarily mean that the phone manufacturer have enabled the particular feature on it. In any case, we expect the smartphone manufacturers to include the functionality in almost all their devices – irrespective of the price range that the phone is marketed at.
