Many users wonder if eSIM has a weaker signal than physical SIM? The answer is no. eSIM is just a form of storing electronic SIM information in the device, it does not reduce signal quality at all. However, because it is a new technology, eSIM has a weak signal or lost signal, which can be due to the device configuration not being up to standard, software errors or being in an area with weak signal.

When the eSIM has no signal, you may encounter many inconvenient situations such as not being able to make calls, not being able to access the 4G/5G network, or even losing the ability to communicate while moving. This is especially likely to happen when you are standing in areas with weak signals such as basements, elevators, rural areas far from the center, or high-rise buildings with signal-blocking structures.

Understanding the impact of eSIM signal loss is essential, but more importantly, you need to understand the root cause of this situation. Identifying the right cause will help you choose the right solution, avoiding wasting time trying ineffective measures. Below are common reasons why eSIM signal loss or weak signal occurs.

Weak coverage or no signal

One of the most common reasons for eSIM signal loss is that you are in a place with poor signal, such as a remote area, basement, area with many high-rise buildings, or enclosed spaces. Additionally, the carrier may be experiencing technical or maintenance issues that cause signal interruptions.

Activation error or incorrect installation

Some users have encountered errors due to incomplete eSIM activation or incorrect network settings. Selecting the wrong frequency band or enabling the wrong network mode (such as only selecting 2G or 3G) can also cause weak signal or no service.

Outdated phone software or application conflicts

Outdated operating systems (especially older iOS or Android) can cause conflicts that prevent eSIM from working properly. Some conflicting apps can also affect the network signal.

Accidentally turned on airplane mode

It sounds simple, but many people turn on airplane mode without realizing it, causing their phones to lose connection to the mobile network.

Hardware error

While eSIMs don't require a slot like a physical SIM, the modem inside your device can fail, causing a loss of signal. This is rare, but something to consider if you've tried other methods and they haven't worked.

eSIM error

Some eSIMs may experience technical errors during download or setup. In this case, you will need to replace the eSIM with a new one from your service provider.

Once you have determined 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 the basement, enclosed space, or area with poor signal to make sure your phone can reconnect. You can ask around to see if anyone else is experiencing the same problem to determine if it's an area issue or a device issue.

Turn off airplane mode

Check your phone to see if airplane mode is 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, make sure you're running the latest version of iOS or Android. Many connection issues can be fixed in these updates.

Restart your device

This is a simple but effective method that many people often apply. Restarting helps the device refresh the network connection and resolves temporary errors that cause signal loss.

Reset network settings

Go to Settings > General > Reset > Reset Network Settings. This won't erase any data, but you'll need to re-enter your Wi-Fi password and reconfigure your VPN (if applicable).

Check battery and case

A low battery can cause your device to lose performance, affecting your signal reception. Also, if you have a case that is too thick or contains metal, remove it to help improve your signal.

Contact service provider

If you have tried all of the above and still have no signal, please contact your carrier (e.g. Aviro) for assistance. We are always ready to help you check, fix errors and reissue eSIM if needed.
