How to set the default SMS card in three-card and three-standby mode?

Nowadays, smart phones have multiple SIM card slots, such as single card dual standby, dual card dual standby, three cards and three standby modes, which allow users to use multiple mobile phone numbers and service providers on the same mobile phone. However, when using multi-card multi-stay, there will be some problems. For example, I want to send a text message, but I don't know which card to use. So how to set the default SMS card in the three-card and three-standby mode?

First of all, you need to enter the phone settings interface and find the "SIM card and mobile network" option. Here, you can set your default data card and default voice calling card, but there is no default SMS card option.

So what should we do? In fact, in the three-card and three-standby mode, just insert the SIM card you want to set as the default SMS card into the SIM 1 slot of the mobile phone. Because in the three-card and three-standby mode, the mobile phone uses the card in the SIM 1 slot as the SMS card by default. If you want to change the default SMS card, just change the corresponding card.

However, this method is only applicable to the three-card three-standby mode, because in other modes, such as the dual-card dual-standby mode, you need to enter the SMS application to set it. Open the application, click the "Settings" option, and then select "SMS Settings", where you can change the default SMS card.

In short, if you want to set the default SMS card to the mode of three cards and three standby cards, just plug it in the SIM 1 slot. In other modes, you need to set it through the SMS application. I hope this article can help you solve the problem.
