Almost all phones Xiaomi support 2 SIM cards simultaneously. In this article, we will consider all the network and Internet (data transfer) settings for each sim card. So let's go.
Settings for each SIM card
See all options here: Settings> Sim cards and mobile networks.
When 2 SIM cards are working in the phone at the same time, you will see the signal of two cellular networks at the top (next to the charge level). For each SIM card, you can configure the use of a mobile network and data transmission (access point).
After choosing any SIM card, we will get to the settings menu, where the following options will be available:
- Enable SIM card. If you do not use this SIM card for a long time and do not receive SMS and voice calls on it, then it can be turned off to save battery power.
- SIM card name. Set any name so as not to be confused with the second – write the name of the operator.
- SIM card number. A convenient option if you forgot your phone number.
- Access points (APN) – which access point this SIM card uses to access the Internet and receive mms messages. These settings come the first time you insert a SIM card into the phone, and are installed automatically. You don't need to change anything. Alternatively, you can manually add an access point.
- Preferred network type: 4G (LTE), 3G or 2G (calls only, no internet, to save energy).
- Mobile networks. Select network automatically or manually. I recommend automatically, especially if you are in roaming – the most “friendly” and inexpensive partner operator will be selected. Experienced users can choose the manual mode, while in roaming they take on all the risks (they can “get” on an expensive tariff from another operator). For example, in manual mode, besides my Beeline network, there are also networks available, but it is not a fact that I can connect to them: MTS 4G, Tele2, Megafon 4G.

basic settings
These settings affect all working SIM cards, and not each separately:
- Mobile Internet: on / off. Allows data transmission via the operator's mobile network.
- Dual 4G mode. Simultaneously, both SIM cards can work in 4G mode (fast internet + calls). But this will quickly drain your phone's battery.
- Mobile Internet during VoLTE calls (voice call transmission over high-speed LTE, or 4G networks). Those. during such a call, the Internet will work on the second sim card. The option is supported by the Big Three operators in Russia: Megafon, MTS, Beeline.
- Data transfer – traffic limitation for each sim card.
- Roaming Internet – whether to use it or not. Remember the super-expensive internet rates in other countries.
- Always accept MMS – receive these messages even when the Internet is disconnected.
- Default calls. Choose which SIM card (preferred) you will be calling from.
- Default Internet. Choose which SIM card you will use the Internet on.

Data transfer
Here we can configure the use of the Internet for each SIM card separately, depending on your tariff plan. Go to Settings> SIM cards & mobile networks> Data connection.
Turn on “Traffic control” and go to setting up the “Tariff plan”:
- Traffic limit – set a monthly traffic limit. For example, I have it 2GB / month.
- If exceeded, notify and turn off the Internet, or simply notify.
- Warning threshold – when I see a warning – 80%, i.e. after 1.6GB of used traffic package.
- Accounting start date – from which day of the month to start calculations. Usually the tariff is valid from the first day of each month.
And use the following options as additional settings:
- Widget in the notification curtain – whether to show the widget or not.
- Show network speed – the current speed of the Internet connection.
- Send traffic reports. I advise you to disable sending reports to Xiaomi.
- Disclaimer – a license agreement that the company and the cellular operator do not owe you anything, all risks are solely on the user himself.
