How to hide your phone number on Xiaomi Redmi 7: all the ways with instructions

Why Hide a Redmi 7 Number and When It's Not Allowed

Hiding a number on Xiaomi Redmi 7 is a pressing task for those who value privacy or want to avoid unwanted return calls. In 2026, this smartphone is still used by millions of users, but not everyone knows that the ability to hide a number is limited by operators and legislation, for example, in Russia since 2022 there are strict rules for identifying subscribers, and some mobile operators block hidden calls by default.

It's important to understand that hiding a number doesn't make you completely anonymous. The operator always sees your real number, and in emergency cases (call 112, police or ambulance), your ID will be transmitted automatically. However, for everyday tasks - calls to support, sellers or unfamiliar contacts - hiding the number remains a useful feature.

Method 1: Hiding a number through phone settings (the easiest method)

Redmi 7 running MIUI 10-12 has a built-in number hiding feature, but it depends on the firmware and operator to check its availability:

1. Open the phone application (pipe icon).
2. Click on the three dots in the upper right corner → Settings.
3. Select Additional Settings → Caller Identification.
4. If you have the option to hide the number, activate it.

⚠️ Attention: Many Russian operators (MTS, Beeline, Tele2) may not have this item or be blocked. If there is no option, go to the following methods.

If the feature is available, all outgoing calls will be automatically hidden. To undo the cover-up for a specific contact, add the *31# prefix before the number (e.g. *31#79123456789). This will temporarily disable the cover-up for a single call.

Method 2: USSD-Number hiding codes (works for most operators)

USSD-Codes are a universal way to control the concealment of a number, independent of the phone model:

3. Enter the code (e.g. *31#) and press the call button.
4. Wait for notification of successful activation.

Important: operators "Yota" and "Tinkoff Mobile" USSD-codes may not work – they block hidden calls at the network level.

Method 5: Alternative methods (internet calls and instant messengers)

If you can't hide your phone number through the operator, you can look at calls over the Internet. Many instant messengers allow you to call without displaying your phone:

• 📱 WhatsApp – calls are made over the Internet, the number is visible only if the subscriber is saved in your contacts.
• 📱 Telegram – supports voice calls with hidden number (if the subscriber does not know your account).
• 📱 Viber – you can call via a virtual number (configured in your profile).
