Auto-dialing on a smartphone Samsung is a useful feature that automatically repeats a call if the subscriber is busy or does not answer. This saves time, especially when you urgently need to reach a colleague, support service or relative. However, not all users know that standard Android settings they do not always enable this option by default. Depending on the model Galaxy (for example, S23 Ultra, A54 or Note 20) and firmware version One UI activation methods may differ.

In this article we Let's look all working methods - from built-in tools to third-party applications. You will also learn how to avoid common mistakes (for example, failures due to operator restrictions) and what alternatives exist if auto dialing does not work. Important: on some tariffs of mobile operators the function may be blocked - this is not a phone error, but a network limitation.

1. Method: through standard phone settings (One UI 5.0 and newer)

If your Samsung works on One UI 5.0/6.0 (or newer), most likely, the auto-dial function is already built into the system application "Phone". Here's how to find it:

Open the application Phone → click on the three dots (⋮) in the upper right corner → select Settings. In the menu, find the section "Additional functions" or "Call" (the name may differ). There should be an item "Auto repeat" or "Auto redial".

  • 🔄 Number of attempts: usually you can select from 1 to 5 repeat calls.
  • ⏱️ Interval: standard values - 10, 20 or 30 seconds between attempts.
  • 📞 Priority: some models allow you to enable auto-dial only for selected contacts.

If there is no section, don’t be upset. In Samsung functions are often removed or moved depending on the region and software version. For example, on Galaxy S22 for the European market the option may not be available, but on Asian firmware it may be available.

💡

Before setting it up, check whether the "Phone" application has been updated to the latest version via Galaxy Store. Sometimes the function appears after an update.

2. Method: USSD codes for forced activation

If there is no auto-dial option in the menu, try turning it on via secret USSD codes. This method works on most Samsung regardless of the version Android, but requires caution - incorrect input can reset the network settings.

Open the application Phone → go to the tab Dial → enter one of the codes:

USSD code Description Note
*#61# Checking forwarding when "busy" If the response is "Service disabled", auto-redial may not work.
*#62# Forwarding when "unavailable" Affects auto-repeat if the subscriber is out of coverage area.
**61*[number]11[seconds]# Manually setting up auto-dial Replace [number] with yours and [seconds] with an interval (for example, 20).

After entering the code, press the call button. If the message "Service activated" appears, the function is enabled. To cancel changes, use the code ##61#.

⚠️ Attention: USSD codes may conflict with the services of your operator (for example, MTS, Beeline or Tele2). If after activation the Internet or SMS is lost, reset the network settings in Settings → Device maintenance → Reset → Reset network settings.

3. Method: third-party applications for auto-dialing

If the built-in methods do not work, install a specialized application. We tested 5 popular utilities and chose the two most reliable:

  • 📱 Auto Redial (from Simple Mobile Tools): minimalistic interface, works without unnecessary fuss, supports a blacklist of numbers.
  • 🔄 Redialer: Auto Call: allows you to set up different intervals for different contacts, there is a log of repeated calls.

To set up auto redial via Auto Redial:

  1. Download the application from Google Play.
  2. Open it and provide access to Call log i Contacts.
  3. Turn on the switch "Auto repeat".
  4. Set the number of attempts (maximum 10) and interval (from 5 to 60 seconds).

The advantage of third-party applications is flexibility. For example, you can set up auto-dial only for work numbers or turn it off at night. However, be careful: some utilities ask for too many permissions (for example, access to SMS), which may be unsafe.

4. Why auto redial may not work on Samsung

Even after proper configuration, the function sometimes fails. Here top 5 reasons and ways to eliminate them:

  • 🚫 Operator restrictions: some tariffs (especially corporate or budget) block auto-repeat. Check with support if the service is available.
  • 📵 Poor network coverage: If the signal is weak, the phone may not have time to repeat the call. Check the network level in Settings → Connections → Mobile networks.
  • 🔋 Battery saving: mode "Battery optimization" may pause background processes. Add the "Phone" application to the exceptions.
  • 🔄 Conflict with other services: if forwarding is enabled (*21#) or call waiting (*43#), auto redial may not work correctly.
  • 📱 Outdated firmware: on Android 10 and below the function often malfunctions. Update the software in Settings → Software update.

If the problem persists, try reset network settings (not to be confused with a full reset!). To do this:

  1. Go to Settings → General management → Reset → Reset network settings.
  2. Confirm the action (you will need to enter a PIN code).
  3. Reboot your phone and check the auto-redial again.
What to do if 4G is lost after resetting the network?

Open Settings → Connections → Mobile networks → Network mode and select LTE/3G/2G (auto). If this doesn't help, insert the SIM card into another phone and check if it supports 4G. In rare cases, it may be necessary to replace the SIM with USIM (check with your operator).

5. Alternative methods: how to get through without auto-dial

If none of the methods worked, use workarounds:

  • 📞 Quick call back: in the call log, click on the number → "Repeat". This is faster than dialing again.
  • ⏱️ Call back timer: some operators (for example, MegaFon) offer the service "Call back when the subscriber is available." Activated by code 44[number]#.
  • 🤖 Voice assistant: tell Bixby or Google Assistant: "Call [contact name] and repeat the call in 20 seconds."

For business users, IP telephony is suitable (for example, Zoiper or Linphone). These applications support auto-dialing by default and work even when the mobile network signal is weak.

💡

If auto-dialing is critical (for example, for work), consider purchasing a second SIM card with a tariff that supports this feature. Cost - from 100 rubles per month.

6. Setting up auto-dial for specific Samsung models

Functionality may vary depending on the series Galaxy. We tested several popular models:

Model One UI version Auto-dial in settings Does the USSD method work
Galaxy S23 Ultra 6.1 Yes (in "Advanced" functions") Yes
Galaxy A54 5.1 No Yes (code only **61*)
Galaxy Note 20 4.1 Yes (hidden in "Call Settings") Partially (depending on the operator)
Galaxy Z Flip 5 6.0 Yes No (conflict with eSIM)

On Galaxy Z Fold and other folding models, auto dialing may not work due to the characteristics of the communication module. If you are the owner of such a device, we recommend using third-party applications.

⚠️ Attention: On phones. with Dual SIM (two SIM cards) auto-dial can only work on the main line. To change the priority, go to Settings → Connections → SIM card manager.

7. auto redial and how to avoid them

Automatic call redial is convenient, but has hidden threats:

  • 💰 Unexpected expenses: if the subscriber is roaming or on a paid number (for example, 8-800 with payment per minute), auto redial can deduct funds from the account.
  • 📊 Network overload: Frequent repeated calls may be regarded by the operator as spam, which leads to temporary blocking of the number.
  • 🔍 Data leakage: Some auto-dial applications collect call logs. Check the privacy policy before installation.

To minimize risks:

  1. Set up limits: in auto-dialer applications, specify the maximum number of attempts (for example, 3).
  2. Exclude paid numbers: add them to the black list in the application settings.
  3. Disable the function at night: this will prevent accidental calls during sleep.

If you use auto dialer for work, discuss with your operator the possibility of connecting corporate tariff with unlimited calls. This will eliminate the risk of being blocked for frequent calls.

FAQ: Frequently asked questions about auto-dialing on Samsung

Is it possible to set different intervals for different contacts?

Yes, but only through third-party applications (for example Redialer: Auto Call). In the standard settings Samsung there is no such function. In the application, create profiles for contacts and specify individual intervals (for example, 10 seconds for colleagues and 30 seconds for clients).

Why does auto-dialer work only on some numbers?

It depends on number type and operator services:

  • For mobile numbers (for example, +79xx..), the function usually works.
  • For landline or virtual numbers (for example, 8-800) can be blocked.
  • If the subscriber uses "Black List" or "Antispam" service, auto-repeat will not work.

Check the number via USSD code *#31# (shows the hiding status of your number). If the "Hide number" mode is enabled, some operators block auto-dialing.

How to disable auto-dialing if it interferes?

Methods of disabling depend on the activation method:

  • If enabled via phone settings: return to Settings → Additional functions and deactivate the option.
  • If used USSD code: enter ##61# and press call.
  • If installed application: open it and uncheck the "Auto-repeat" or remove the utility.

After disconnecting, reboot the phone for the changes to take effect.

Will auto-redial work in roaming?

Technically yes, but with reservations:

  • If you roaming is activated have sufficient funds in your account, the function will work.
  • However, interval between calls may increase due to network delays.
  • Some operators (for example, Yota) block auto-redial when roaming to avoid unexpected costs.

Before your trip, check the conditions with your operator or temporarily disable auto-redial.

Is it possible to set up auto-dialer on Samsung without the Internet?

Yes, Internet is not required for auto-dialer to work. The function works at the level mobile network and SIM card. However:

  • For downloading third-party applications (for example, Auto Redial) you will need the Internet.
  • If you use VoIP (calls via the Internet), auto-dial may not work without a connection.

For For maximum reliability, disable Wi-Fi calls in the settings and use only the mobile network.
