How many? SIM-maps in Xiaomi Redmi 6A: detail + setup

Xiaomi Redmi 6A — One of the most popular budget smartphones of 2018, which is still in use today for its reliability and easy maintainability. SIM-maps: is it a model with one SIM, or supports two nanoSIMs, or maybe there is a slot under microSD? In this article, we will analyze all the nuances - from technical specifications to step-by-step configuration of two sims.

The big question is that Redmi 6A officially supports 2 nanoSIMs in a hybrid slot, which means you can use either two SIMs or one SIM + memory card. But there are pitfalls: not all operators work correctly in pairs, and setting network priority requires manual intervention. Next, detailed analysis of photos, compatibility tables and solutions to typical problems.

Technical characteristics of the SIM slot in Redmi 6A

The smartphone is equipped with a hybrid slot type nanoSIM + nanoSIM/microSD. It means:

• 📱 Two nanoSIMs – two SIM cards work simultaneously (for example, MTS) + Tele2).
• 💾 One nanoSIM + microSD – if you need a memory card, you will have to sacrifice a second SIM.
• ⚠️ No eSIM support, only physical cards.

Important: the slot does not support microSIM or miniSIM format - only nanoSIM (size 12.3×8.8 mm). If your SIM is old, it will have to be cropped or replaced in the cabin of the operator.

The manufacturer claims support for Dual SIM Dual Standby (DSDS) - this means that both SIMs are active at the same time, but during a conversation on one of them the second will be unavailable (calls are forwarded to voice mail).

Where is the slot for SIM-map 6A?

The SIM tray is located on the left side of the smartphone (if you hold the screen to yourself).

1. Turn off your phone (but not necessarily).
2. Take a paper clip or a special key from the kit.
3. Insert it into a small hole next to the slot and press before clicking.
4. The tray will move out - carefully pull it out.

After installing the sim phone will automatically determine the network, but for proper work you need to set priorities:

1. Go to Settings. → SIM-maps and mobile networks.
2. Select Control. SIM-map.
3. Set up: 📞 Calls – Select the SIM for the outgoing default. 📶 Mobile data – specify which SIM will be used for the Internet. 💬 SMS – set up a SIM to send messages.

Always ask

🔹 Tip: If one of the sims does not catch the network, try to manually select the operator in the Settings menu → Mobile network → Network selection. Sometimes automatic search fails.

💡

If the phone doesn't see one of them after you install the SIMs, take out the tray and check if the cards are tightly seated in the connectors, and often the problem is not enough contact.

Operator compatibility: Which SIMs work together?

Theoretically, Redmi 6A supports any combination of operators, but in practice there are conflicts.

⚠️ Note: If you use MegaFon or Beeline with active VoLTE option, the second SIM may be disconnected from the network periodically.Solution: disable VoLTE in the settings or use SIMs without this feature.

Problems also arise if:

• 🔄 Both SIMs are online. 4G — The phone can "hang" when switching.
• 📡 One of the sims uses 3G, second — 2G (For example, to save the battery).
• 🔒 Parental control or operator restrictions activated on the SIM.

Frequent problems and their solutions

Redmi 6A sees the other SIM-map 30% cases due to improper installation of the tray or conflict of operator profiles.-5 problems and ways of eliminating them:

1. The Simka is not detectable: Check if the card is inserted correctly (chip down). Clean the contacts of the tray with alcohol. Try inserting the SIM1 into the SIM1 - sometimes SIM2 is glitchy.
2. No network in one of the sims: If the network goes missing after the software update, reset the network settings: Settings → System → Reset → Network settings Reset. This will delete the stored Wi-Fi and passwords, but restore the connection. Reboot the phone. Manually select the operator in the settings. Check the balance and activity of the operator.
3. Mobile Internet is not working: Make sure the Internet is connected to the right SIM (Settings) → Mobile network. Check it out. APN-settings (request the operator).

If nothing helps, try resetting your network settings:

Settings → System → Additional → Reset → Network settings reset

This will remove all stored Wi-Fi and Bluetooth devices, but often resolves SIM problems.

Can you use a microSD with two? SIM-map?

• 📱 Two. SIM-cards without microSD.
• 💾 One. SIM + microSD – maximum flash drive capacity up to 256 GB (officially supported).

🔹 If you need two SIMs and memory critically, consider options:

Use cloud storage (Google Drive, Yandex.Disk).

- Buy it. OTG-adapter to connect the flash drive through USB (But it's inconvenient for permanent use).

- Move frequently used files to the second SIM (if the operator supports storage on SIM, as some Tele2 tariffs do).
