How to remove service numbers from a SIM card. How to clear SIM card memory

Update 04/28/2019

If you've been storing new contacts on your Android smartphone's SIM card but now decide to delete them, we'll tell you how you can do this.

We will look at instructions on how to delete contacts from an Android SIM card on a Samsung Galaxy S5 smartphone, but it can be used for any mobile device.

How to do it?

In the latest versions of the operating system, you cannot delete mobile numbers from a SIM card. This was done with the advent of the synchronization function in smartphones. The saved numbers are transferred to your Google account, cloud services from Samsung or other storage facilities. Using technology makes it possible to transfer important information when changing phones by simply logging into your profile.

Chinese manufacturers have added the function of displaying and deleting contacts from an Android phone. The instructions will show screenshots taken on a model from the manufacturer Xiaomi; in other shells the action algorithm may differ.

Go to the Contacts application. To get to the settings menu, hold down the context menu key. The button is located in the lower left corner, regardless of whether the smartphone has additional keys at the bottom or they are on the screen.

Click on the “Display” item. The section is responsible for the appearance of the list and the elements that are in it.

We switch the “SIM Contacts” item to the active state and return to the list. All entries saved on the SIM card will be shown. Press and hold the desired element and select the “Delete” line from the context menu to clear the SIM card of contact numbers .

For information: in “Display” there is a “SIM manager” function, in which the user can find out what elements are saved on the SIM card. Need to call someone quickly? Read about this in the article: “How to set up speed dialing”

Cleaning out your folders

Sometimes, by accidentally looking into the “Documents” folder, you can find, for example, a PDF file that weighs 200 megabytes, downloaded several months ago and already forgotten. A quick analysis of several folders can free up tens of megabytes, and in extreme cases, even more than a gigabyte of space.

Which folders should I pay attention to? Documents, downloads, music, photos, films, podcasts. A photo of a schedule from a city visited during the holidays, a PDF with a small report that has lost its meaning, rarely listened to music, a movie with a cat. Well, you know what data I mean. Don't be afraid to remove them!

Sometimes it happens that Android does not see the contacts on the SIM card simply because their display is disabled in the settings. In this case, only those stored in the device’s memory are displayed. This is the most common situation and the easiest to resolve. This usually happens when a smartphone falls into the hands of children and they start clicking anywhere.

If the numbers do not appear, and all previous actions have not brought results, you can try resetting the settings. To do this, go to “Settings” - “Backup and reset” - “Reset settings”. On different smartphones and versions of the Android system, the name of this item may differ slightly, but it is not difficult to find.

Remember that some data may be deleted during a reset, so copy photos, music, and anything valuable that you don’t want to lose to your computer in advance.

Such an operation is similar to reinstalling the system on a computer and can also work wonders. Over time, files and applications accumulate on your smartphone, and various settings change. All this ultimately leads, sooner or later, to a drop in performance and noticeable “slowdown” of the device. A factory reset solves many problems, even those that have no apparent cause. This may include contacts on the SIM card.

How to quickly remove data from your Google account

A common problem is how to delete contacts from your phone so that they are not transferred to another device when you change your smartphone. Due to synchronization with Google, all information is automatically transferred to the new mobile phone.

To fix this, go to the system settings, to the “Accounts” section. We find a Google profile that will be linked to the new device. Click on it and uncheck the box next to the synchronization item shown in the screenshot.

From this moment on, information will not be transferred to the company’s servers. We remove unnecessary people from the phone book and enable the exchange of information with the company’s servers. The device will automatically start updating the data. Read what to do if numbers won’t load in the material: “Contacts won’t load on Android”

How to permanently delete a contact and number from your Android phone

If you are the owner of a modern smartphone, then even editing your contact list can be difficult. It's all about synchronization, which prevents you from changing phone numbers in memory at will. In addition, the device collects numbers from popular instant messengers into one list, and this causes additional difficulties. Let's figure out how to delete a contact or phone number from a smartphone.

Basic tools

The easiest way to delete a contact from an Android phone is to use basic functions. To do this, you need to go to the phone book and press your finger on the contact to be deleted. Select the “Delete” item in the context menu and complete the operation. Some dialers support selecting several contacts or all at once.

All dialer programs have this functionality, so there shouldn’t be any difficulties here. Basic capabilities allow you to delete contacts stored in any source, from a SIM card to a Goole account. To switch between sources, go to the application settings and find the contact list display settings item there (may be called “Show contacts”). By tapping on this item, you will see a list of sources:

• All contacts (the entire list is displayed at once);
• Device (referring to the internal memory of the phone);
• SIM1 and SIM2 (for devices with two SIM cards);
• Google account (visible as [email protected]).

There may also be other items here that appear after installing various applications (Skype, WhatsApp and Viber messengers, applications for social networks VKontakte and Odnoklassniki).

If you want to access all contacts at once, select “All contacts” - records from all sources will appear in the list at once. The process of deleting records will be the same as we described above - press one contact, mark other contacts, select the delete option.

To avoid confusion in phone numbers in the future, copy your phone contacts into one source. The best option is to copy everything to your Google account so that the records are synchronized with the servers of the Android operating system developer.

Standard way to delete a contact

On phones with the Android operating system, there is an easy way to edit your contact list. To do this, you need to find an application that stores a list of them. Usually it is called “Contacts”, but it can be different. Its pictogram is a notebook with a schematic image of a person on it.

Next, the instructions will tell you how to delete a phone number on Android:

When you click on the desired line, the operating system may behave differently. Sometimes the menu does not appear, and a line is activated at the top of the screen, which schematically displays the available actions. In this case, you need to select an icon that resembles a trash can or trash can.

Also, sometimes the interface of this application involves calling up the menu not by holding your finger for a long time, but by a special button.

In this case you need:

If none of the menu methods work, press the leftmost button at the bottom of the screen. It is used for an alternative menu call. There you can also delete a contact or change it.

If the SIM card only has service numbers that you do not use, then you need to disable its display in the list, then they will not interfere with you. To prevent SIM contacts from appearing in the main list, you need to disable their inclusion in the general list through the settings. This is done through the "Display" tab in the menu.

Batch deleting contacts from your phone

If you want to carry out a global wipe of contacts, you can do a mass deletion. Depending on the operating system configuration, this is done in two ways.

The simplest option for batch deleting numbers and contacts:

More modern versions of Android have a Batch Uninstall option. To do this, you need to go to the Contacts application and call up the settings menu using the touch key under the screen (far left).

Then follow these instructions to delete contacts:

These are the main ways to delete several contacts at once, but using them is not always convenient. If you want to completely reset your notebook, you need to do it differently.

Disabling an account

If you want to completely reset your contacts list, you will need to disable the account they are synced with. This option will be useful if you are preparing a phone for sale or, on the contrary, you bought a smartphone secondhand and want to get rid of other people’s numbers. Account deactivation is carried out according to the instructions:

This way, you can leave only contact lists from instant messengers in memory, and delete previously saved numbers. If, on the contrary, you want to delete contacts that appeared in memory due to the use of instant messengers, then you need to disable accounts in them from synchronization. This way, you will get rid of displaying in your phone book the numbers of social network users who are among your friends, and you will also not have to look for the necessary numbers among the data of unfamiliar people with whom you communicated via messaging in any of the popular instant messengers.

Editing Google Synced Data

If you duplicate the list of contacts in your Google account, you can not only delete it entirely, but also edit it and then synchronize the device with the account. This is convenient if you have a lot of numbers in your address book and you don’t know how to remove a phone number from your account without deactivating it. Follow the instructions:

If, after selecting contacts in the browser, the “Trash” button is not active, this means that some of the numbers in the list were saved using Google +. In this case, you need to go to Circles and delete these contacts there. After that, go to Contacts and repeat the operation.

Duplicate contacts: how to merge and delete unnecessary ones?

Another problem for Android users is duplicate contacts. They appear when different firmware is installed on the device and subsequent synchronization. As a result, the book of numbers increases significantly and you will have to scroll through more than usual to find the desired contact. There is an exit. To begin with, you can try to cope with duplicates using the operating system. The standard Contacts application has a function for merging duplicate entries. To do this you need to do the following:

Delete contacts using special programs

In older versions of Android OS, this function may not be available or may not work correctly. Therefore, you can not merge contacts, but delete them. To do this, you can use standard batch deletion, but if you have a large phone book, then manually searching for identical entries will take a lot of time. It is best to use special utilities. One of the simplest and most accessible is Duplicate Contacts. You need to work with it according to the instructions.

How to Delete Duplicate Contacts in Google Contacts

If your phone is synchronized with a Google account and the information is stored on its server, then you can delete duplicates differently. The steps will be similar to those you followed to edit the list. You will need to do the following:

If some of your contacts were synchronized from Google +, then similar actions need to be carried out in the “Circles” tab. In order for the contact list to be displayed correctly in the phone memory, you must complete editing using synchronization. It must be done through “Settings”. Make sure your account is activated and participating in synchronization. Some custom firmwares disable it.

Now you know how to remove a phone number from the main list on your smartphone. We told you about all the methods that work on Android OS. Share information with friends, ask questions and share your observations in the comments. Feedback is welcome!

If there are no problems with clearing the SIM card of unnecessary entries, then the question of how to delete individual contacts on Android synchronized from other applications often leads to a dead end. A deleted contact constantly returns back to the phone book, so many users simply stop contacting it. The problem is solved by disabling synchronization.

After turning off synchronization, you can safely delete entries from your book and applications without worrying that they will come back.

You don’t need to enter them, you just need to press a button to call up the menu; not everyone will think of clicking there. We need to click on the button with three lines in a square; previously it had the name “Menu” or “Functions”, but now it’s just a square with lines.

Ways to clear SIM card memory manually or through a program

A SIM card is a subscriber identification module, a kind of microcomputer. It stores a large amount of information - contacts, messages, SIM card data. If the SIM card memory is full and a corresponding message appears on the phone, it must be cleared.

Clearing the SIM card memory is not difficult - you can use several methods to do this, which will differ depending on the phone model and the operating system installed on it.

In simple phones with Java support, you can clear the phone memory directly through contacts. To do this you need:

• Go to the phone menu;
• Find the “Phone Book” or “Contacts” section;
• Select the “Delete” item. To completely clear the SIM card, use the “Delete all” command;
• Select “SIM card”;
• Confirm deletion by clicking on the “Ok” button

There is nothing to demagnetize there!

In fact, a SIM card is one of the types of processor-based “smart cards” that differ depending on the supported mobile communication system. Next we will talk specifically about SIM cards working in our GSM networks.

Today, there are four standard sizes of SIM cards:

When you buy a card now, you get a chip on a universal piece of plastic that meets all these standards. And whatever the form of SIM cards, they have one thing in common: this is a real computer in miniature . A small chip with six contacts (previously there were eight) contains almost the same components as in a regular system unit. The SIM card contains:

Of course, there is no battery or any kind of human interface, they are simply not needed. But the small SIM card has its own operating system, which allows you to store vital data for the phone, user files (contacts, SMS) and even Java applications.

Due to the desire to reduce the cost of components, operators issue cards with a minimum of memory, but technically, gigabytes of information can be stored on SIM cards. Of course, no one needs this, there are no terminals operating in this mode, and it’s easier to operate a large amount of data via USB.

Do you understand now? This is a board with contacts. There are no magnetized elements here. The principle of data recording has nothing to do with magnetism. Accordingly, there is nothing to be demagnetized.
