SIM Card Replacement

  • Detect if your child is using a secret SIM card.
  • Get notified if a new SIM card is activated on your kid's phone.
  • Monitor every activity, even if a SIM card has been replaced.
  • Find out what your child is hiding with another SIM card.

What Is the SIM Card Replacement Feature?

Reasons why your child might be using two SIM cards may differ. But no matter what the reason is, you should be aware when it happens. uMobix will let you know when your kid decides to replace the SIM card. Using a SIM card tracking feature will help you to notice this change right on time. The SIM card replacement detecting feature is a tool that tracks when a new SIM card is installed on a target device. As soon as your child uses a new SIM card, you will get an instant notification on your dashboard.

If your kid doesn't own a dual SIM smartphone, there is most likely no obvious reason for using another SIM card—as long as there is nothing to hide from your parents. A SIM card replacement is a useful tool that will monitor not only key activities, such as messaging, calling, or using any social media apps, but will also detect if your child replaced a SIM card.

How Does SIM Card Replacement Work?

uMobix notifies you when the SIM card in the tracked device is replaced in real time, but it is completely unnoticeable on the target device, and there is no way it can compromise your privacy; anonymity is guaranteed. If your child changes their phone number - you will know immediately. Here is how to proceed:

  1. Register with the uMobix mobile tracker, choose the plan you want to use, and install it on the target device.
  2. Log into the online profile from your own device. uMobix sends you the credentials for this to your e-mail.
  3. View the dashboard. Here, you can check the information about the SIM card inserted in the device now (carrier) and the date of the last SIM card change.

Frequently Asked Questions

Can you track the location of the location of a SIM card?


Yes, for this, you need to know the unique SIM card number. Contact your mobile network provider and ask them to use geolocation to find out where your SIM card is. As long as it is inside the phone, it will work. If your phone is stolen and has no SIM card, you cannot detect where it is unless its SIM card is absent.

How can I track my lost SIM card?


You cannot track a SIM card on its own. It needs to be inside an operating device. As soon as a phone with your SIM card installed turns on, the IMEI number of the phone and serial card number will be passed to the nearest cell tower. A SIM card alone cannot be tracked, since it has no power in it. uMobix will let you track the target device's location even if the SIM card has been replaced or removed.

How can I track my SIM card online?


When you want to find out where your target device is at the moment, you can detect its location with the help of a SIM card only. Go to geofinder.mobi website and use this tool to find out the phone's location. In case your device gets lost, you can track where your phone is online. If you have uMobix installed on it beforehand, you will also be able to spot its location.

How to easily tell if someone has switched a SIM card?


It's quite hard to tell when someone switches a SIM card. You can find it out rather accidentally or check if this person has a dual SIM card device. The other way to find it out is to get the target device in your hands and check the phone number it has at the moment. uMobix will let you know when it was replaced with the exact date.

Will I know if my child changes the SIM card?


Yes, uMobix sends you a notification whenever the SIM card is switched on the target device. Thus, if your kid has a secret SIM card they use for some secret business - you will know about it the moment it is inserted into the device.

Will I still be able to track all the activity, even with the new SIM card?


SIM card change does not influence anything. uMobix is installed on the device and tracks its activity, not the SIM card, only the internet connection matters. Thus, no matter if the SIM card is changed or not, and no matter how many times it is changed - it will not influence the tracking results.
