to have 5G it will be necessary to deactivate the Dual SIM mode

In unveiling its iPhone 12 last week, Apple largely insisted on one of the main novelties: support for 5G. However, a technical limitation indicates that these new generation networks will not be compatible with dual SIM mode.

From the iPhone XS, XS Max and XR, it is possible to activate a second telephone line thanks to the support of eSIM profiles. Concretely, you can therefore juggle between a classic package linked to a standard SIM card, but also with an additional line.

No 5G in Dual SIM mode

However, activating this eSIM function would lead to a limit: the iPhone 12 would immediately no longer be compatible with 5G networks.

Sure Reddit forums, a user published a support document from Apple intended for mobile operators distributing the iPhone 12. In the latter, it is explained:

When two lines are activated in Dual SIM mode, 5G data is not supported on either of the two lines and will go back to the 4G LTE network. If customers only use the eSIM on a 5G carrier compatible with a subscription, they will benefit from 5G access.

The user who made this information public adds that Apple will deploy an update correcting the problem before the end of this year.

Android also affected

It is interesting to note that this problem also affects Android smartphones. again Indeed reports that the 5G terminals of the Pixel range, presented a little earlier this month, also cannot take advantage of 5G networks when the dual SIM mode is activated.

Sure a support page, Google explains as follows:

Pixel 5 and Pixel 4a (5G) phones with dual SIM cards use 4G networks. To connect to 5G networks, temporarily disable the SIM card that is not configured to use data.

According to Android Authority, there would currently only be a handful of smartphones compatible with a 5G + 5G dual SIM mode. This is the case of the Xiaomi Redmi 10X, Redmi 10X Pro of the Vivo Iqoo Z1 (reserved for the Chinese market). These have in common that they embed one of MediaTek’s SoCs supporting this technology – the Dimensity 820/1000/1000 Plus.

As for Qualcomm, supplier of most of the other Android manufacturers and Apple for its custom chips, support for 5G + 5G dual SIM is not yet in the game.
