Hey there, @Mazhar! Let us help you to find whether it's possible to get an update to your Samsung Galaxy Note 21 Plus from outside the U.S.


To receive the latest software version from AT&T you will need to be an AT&T wireless subscriber, located in the U.S., and on AT&T network. There are other important factors to consider before you can receive your update.


Visit Software update for the Samsung Galaxy S21 5G/Galaxy S21+ 5G/Galaxy S21 Ultra 5G (G991U/G996U/G998U) and check out the detailed information under Getting started:

  • Make sure you’re in the U.S. and on our wireless network.
  • You can download the update via Firmware Over the Air (FOTA).
  • You must connect your device to Wi-Fi to download the update.
  • Although there should be no impacts to settings or data, we recommend backing up your media files to an SD card, a computer, or using a favorite application, before upgrading the software.

Even if you were in the U.S. and connected to the AT&T network, when it comes to using BYODs on our network, devices that are not sold by AT&T may not be compatible with all services. Though AT&T sells the same make/model, a device sold by another carrier or by the device manufacturer may function differently.


It's possible to experience different levels of coverage and data speed, depending on the device's supported frequency bands. Customers with AT&T branded devices can visit Update your phone or device software to learn how to get the most recent version so that they have the latest features and device protection options.

  1. Go to Device Support.
  2. Select or change the selected device brand and model.
  3. Scroll to More Device Help.
  4. Select Software updates if you see it. It only displays if there’s an available update for your device.
  5. Repeat the steps to check for software updates for a different device.

What's more, as advised under the section AT&T branded device:


The software update releases on our website are only available for AT&T branded devices. Keep in mind:

  • The update may not work if you brought your own device to AT&T.
  • You can check with the original carrier or manufacturer for software updates.

We hope this info helps and that you're able to download the most recent software version for your phone. Thank you for reaching out to AT&T Community Forums.
