eSIM, the integrated SIM service provided by Viettel, offers numerous advantages, but users may also encounter instances of eSIM signal loss during usage.
Causes of eSIM Signal Loss
Common causes of signal loss or loss of Viettel network connectivity icons on Viettel eSIMs include:
Coverage Issues
Subscribing outside Viettel's coverage area may result in weak or no signal reception. This is common in areas with challenging terrain, such as mountains, hills, forests, or seas.
Outdated or Incompatible Operating System
This issue commonly affects iPhone users. Using operating system versions that are incompatible with the network can directly impact the signal quality of the eSIM.
Airplane Mode Enabled
If signal loss is not due to coverage issues or OS errors, check if Airplane Mode is enabled. Enabling Airplane Mode and forgetting to turn it off can interrupt eSIM connectivity. Turning off Airplane Mode should resolve the issue.
Damaged eSIM
If the above solutions fail to resolve the issue, the eSIM itself may be physically damaged. Try restarting the device. If the signal issue persists, visit the nearest Viettel service center to replace the eSIM or contact Viettel's hotline for support.
Summary
eSIM signal loss can be caused by various factors, including coverage issues, outdated or incompatible operating systems, enabled Airplane Mode, or physical damage to the eSIM. Applying the solutions outlined above can effectively address these causes and restore eSIM connectivity.
