eSIM Loss of Signal: Causes and Effective Solutions
, by Sim Du Lịch AVIRO, 5 min reading time
SIM cards are becoming increasingly popular in the modern world, especially with international travelers, thanks to their convenience, speed, and the fact that they don't require physical SIM card insertion or removal. However, many users experience issues with eSIMs such as signal loss, weak signal, or no service, affecting their user experience. In this article, Aviro will help you understand the causes and effective solutions to ensure stable connectivity anytime, anywhere.

Many users wonder if eSIMs have weaker signal than physical SIMs. The answer is no. eSIMs simply store SIM information electronically in the device and do not reduce signal quality. However, because it is a new technology, weak or lost signal with an eSIM may be due to incorrect device configuration, software errors, or being in an area with poor signal strength.
When your eSIM loses signal, you may encounter many inconvenient situations such as being unable to make calls, access 4G/5G networks, or even losing communication while on the go. This is especially likely to happen when you are in areas with weak signals such as basements, elevators, rural areas far from the city center, or tall buildings with structures that block the signal.

Understanding the impact of eSIM signal loss is essential, but more importantly, you need to know the root cause of this problem. Identifying the correct cause will help you choose the appropriate solution, avoiding wasted time trying ineffective methods. Below are some common reasons why eSIMs experience signal loss or weak signal.
Weak or no signal coverage
One of the most common reasons for eSIM signal loss is being in an area with poor signal, such as a remote area, basement, area with many tall buildings, or enclosed space. Additionally, the network provider may be experiencing technical issues or maintenance, causing signal interruptions.
Activation error or incorrect installation
Some users encounter errors due to incomplete eSIM activation or incorrect network settings with the wrong carrier. Incorrect frequency band selection or enabling the wrong network mode (such as only selecting 2G or 3G) can also result in weak signal or no service.
Outdated phone software or app conflicts.
Outdated operating systems (especially older iOS or Android versions) can cause conflicts that lead to unstable eSIM functionality. Some conflicting apps can also affect network signal strength.
Accidentally turned on airplane mode.
It sounds simple, but many people turn on airplane mode without realizing it, causing their phone to lose connection with the mobile network.
Hardware failure
Although eSIMs don't require a slot like physical SIMs, the modem inside the device can malfunction, leading to signal loss. This is rare, but you should still consider it if other methods haven't worked.
eSIM is faulty.
Some eSIMs may experience technical errors during download or setup. In this case, you will need to replace your eSIM with a new one from your service provider.

Once you've identified the cause, depending on the specific situation, you can apply the methods below to restore the signal quickly and effectively.
Move to an area with better signal.
Get out of basements, enclosed spaces, or areas with weak signal to ensure your phone can reconnect. You can ask people around you if they've experienced a similar situation to determine if it's a local issue or a problem with your device.
Turn off airplane mode.
Check your phone to see if airplane mode is turned on. If it is, turn it off and wait a few seconds for your phone to automatically reconnect to the mobile network.
Update to the latest operating system.
Go to Settings > Software Update, and make sure you're using the latest version of iOS or Android. Many connection issues may be fixed in these updates.
Restart the device
This is a simple but effective method that many people use. Restarting helps the device refresh its network connection and resolve temporary errors that cause signal loss.
Reset network settings
Go to Settings > General > Reset > Reset Network Settings. This will not erase your data, but you will need to re-enter your Wi-Fi password and reconfigure your VPN (if you have one).
Check the battery and the phone case.
A low battery can reduce device performance and affect signal reception. Additionally, if you're using a thick or metal phone case, remove it to help improve signal reception.
Contact the service provider.
If you have tried all the above methods and still have no signal, please contact your carrier (e.g., Aviro) for assistance. We are always ready to help you check, fix the problem, and reissue your eSIM if needed.
Losing signal on your eSIM can be inconvenient, but most issues can be resolved quickly if you understand the cause and how to fix them. From checking airplane mode and updating the software to reinstalling the eSIM or contacting your provider – everything is easy to do.
