Noticing that your eSIM data package runs out sooner than expected creates suspicion. Is it a plan error? A device issue? Or something more serious, like unauthorized use?
The good news is that, in most cases, high consumption has simple causes. With a few practical steps, you can identify the problem and reduce security risks in the process.
First diagnosis: what is really consuming data
Before touching advanced settings, it is worth confirming the basics. On the phone itself, the data usage section shows which apps have used the internet recently.
Observe calmly: - Apps at the top of the list, especially those you hardly use - Difference between foreground and background consumption - Period analyzed (day, week, or month)
If an unknown or forgotten app appears as the culprit, that already raises a red flag.
Background apps: invisible consumption
Even without opening apps, many continue exchanging data. Social networks, email, cloud services, and even games do this.
For beginners, a simple adjustment helps a lot: - Restrict background data for non-essential apps - Allow full access only for messengers and maps
This step is not just about saving data. Apps running without control increase the attack surface in case of security flaws.
Automatic updates and backups: common eSIM villains
System updates, apps, and photo backups are usually silent. On eSIMs, especially with smaller or international plans, this adds up.
Check whether: - Updates are allowed only on Wi-Fi - Automatic backup of photos and videos is active on 4G/5G
Disabling these options outside Wi-Fi reduces consumption and avoids unnecessary traffic of sensitive data.
Hotspot and sharing: a forgotten risk
Sometimes the consumption does not come from the phone itself. Internet sharing may be enabled without you realizing it.
Confirm: - Whether the hotspot is really turned off - How many devices have connected in the past - Whether there is a strong and up-to-date password
An open hotspot or one with a weak password is a gateway to unauthorized use and consumption outside your control.
When to suspect a fault or misuse on the eSIM
If consumption remains high even after basic adjustments, it is worth investigating less obvious signs: - Abnormal device heating - High usage even in idle mode - Apps that reappear after being removed
In these cases, consider a security check on the system and avoid installing apps outside official stores. The eSIM itself is secure, but the device around it needs to be protected.
Advanced steps: isolation and controlled testing
For those who want to go further, a simple test helps isolate the problem: - Reset the data counter - Use only essential apps for 24 hours - Avoid streaming, downloads, and social networks
If consumption continues to be out of the ordinary, it may indicate an app issue, a system problem, or even a plan configuration issue. This history greatly facilitates contact with the carrier.
Security as a habit, not an exception
Keeping consumption under control on an eSIM is not just a matter of savings. It is also a practical way to reduce digital risks, maintain predictability, and use mobile connectivity with greater peace of mind in daily life.
