              The Causes and Most Effective Solutions for eSIM Signal Loss

              eSIM is Viettel’s integrated SIM service that offers numerous advantages. However, during usage, users may encounter the issue of the eSIM losing signal.

              Common reasons for the situation where the Viettel eSIM loses signal or frequently shows a lack of network connection include:

              • The user is operating in an area where Viettel’s signal is weak.
              • The version of the operating system on the phone is outdated or incompatible.
              • The user has enabled airplane mode, which will lead to the loss of all connections on their device.
              • The Viettel eSIM may be malfunctioning, although this situation is rare.

              esim
              Causes and the most effective solutions for eSIM signal loss.

              How to Fix eSIM Signal Loss

              Subscription Operates Outside Viettel’s Coverage Area

              If users are required to move to areas with complex terrain such as mountains, hills, or deep forests and seas, it is relatively normal for Viettel’s signal reception to be weak or even non-existent.

              In such specific cases, you just need to move to areas with a higher population density. Leaving mountainous, hilly, forested, or deep-sea areas will allow the signal bars to display properly again.

              Outdated or Incompatible Operating System

              This issue is commonly encountered with iPhone models. Using operating system versions that are not compatible with the network provider directly affects the signal quality on the eSIM you are using.

              cap nhat he dieu hanh
              You only need to upgrade the operating system on your device to a higher version.

              According to feedback from some users, iOS versions below 12 seem to lack compatibility with Viettel’s eSIM components. This is also true for eSIM versions from other service providers.

              The solution for fixing eSIM signal loss on iPhones in this case is quite simple; just upgrade your device’s operating system to a higher version. Then check if the signal bars on the eSIM are displayed properly.

              Currently, with iOS 17 on the iPhone 15 Pro Max or iPhone 15 Pro 1TB from Apple’s latest 2023 series, which features 2 SIMs—1 eSIM and 1 physical SIM.

              Disable Airplane Mode on Your Device

              If the cause of the signal loss is not due to being outside the coverage area and is not due to an outdated operating system, check to see if you have activated airplane mode.

              Many users accidentally keep airplane mode on their mobile devices and often forget to turn it off when not needed. This can lead to situations where the eSIM on the iPhone loses signal. At this point, simply disabling airplane mode on the device will effectively resolve the issue of the Viettel eSIM losing connection.

              Your Viettel eSIM May Be Damaged

              If you have tried the three methods mentioned above but the Viettel eSIM still experiences signal loss, the issue may stem from physical damage to the eSIM itself.

              At this point, try turning off and restarting your mobile device to see if the signal bars are displayed properly. If they are still not showing, please visit the nearest Viettel transaction support center for assistance in replacing your eSIM with a new, higher-quality one, or you can directly contact Viettel’s customer service hotline for quick user support information.
