Normally it is very rare to have to send an SMS to your mobile number or have to call it, so it is for this reason that for most people it is not important to know their mobile number, especially in the case of those who have subscribed to a monthly subscription with direct credit to a bank account or credit card and therefore does not foresee having to top up the SIM with other money for the purchase of voice or data traffic. It can also happen, simply, to buy a new SIM with a new mobile number and not have memorized it yet. However, being in possession of this information could sometimes be as important as knowing your name; for example to provide your contact information in the workplace even without being in possession of a business card. In any case, if you do not know the mobile number entered in your smartphone, you can trace this information using the data stored on the SIM card. If you already have your mobile number and are trying to identify the SIM card serial number (ICCID), read this article. In most cases, the ICCID code is printed directly on the SIM card, so you just need to remove it from its slot and write it down on a sheet of paper.
Steps
Method 1 of 7: Contact the Telephone Operator
Step 1. Contact an authorized dealer of the operator who owns the SIM card
If you have found an old SIM card when tidying up your office or desk at home and you don't have a smartphone to check the phone number, you can go directly to a service and sales point of the telephone company that issued it. The store staff should be able to provide you with all the information you need.
Step 2. Call the telephone operator's customer service
If you've just bought a new SIM card, but don't intend to use your company phone to activate it, find the customer service number of the carrier that issued the card. Remember that all SIM cards come with a serial number printed directly on the top. Provide this identification code to customer service personnel so that they can provide you with the associated telephone number.
Step 3. Understand how modern SIM cards work
Most telephone operators assign a mobile number to the card only when the card is sold or activated. When you buy a new SIM card from one of the major Italian operators, the latter is not assigned to any mobile number. The assignment is performed at the time of activation, which is normally carried out directly by the staff of the point of sale you contacted, after which you will be notified of the telephone number that has been associated.
Method 2 of 7: Use the SIM Card in any Mobile Phone
Step 1. Use the operator's customer service
Most telephone operators are equipped with an automatic responder able to provide you directly by voice or via SMS the telephone number associated with the SIM card inserted in the device in use. Call the number related to your telephone operator and follow the instructions that will be given to you:
- Vodafone users can call 190;
- TIM users can call 119;
- Users Three can call 133;
- Wind users can call 155;
- Poste Mobile users can call 401212.
- Smaller operators may or may not have such a service. In this case, search online using the name of the telephone company and the keywords "useful numbers".
Step 2. Call your carrier's customer support
Some SIM cards do not display their mobile number in the Settings application of the device. In these cases it is therefore necessary to call the customer support of the SIM manager directly to get the mobile number to which it is paired.
If you make the call directly with the device where the mystery SIM is installed, the call center operator who will welcome you should be able to automatically trace the phone number to which it is paired. If not, you will need to remove it from your smartphone and provide the support staff with the serial number printed on the card
Step 3. Send an SMS or call another phone number
Sometimes the simplest and quickest solution is the most trivial one. Try sending an SMS or making a call to another number using the device in which the SIM whose mobile number you want to find out is installed. Any mobile or landline device capable of displaying the caller's number will be able to automatically trace the mobile number of the SIM card in use (unless you are using a service that hides this information).

Use the Settings App
Step 1. Launch the "Settings" application

In some cases, a pop-up window may appear asking you to initialize and synchronize the device. If this is the case, press the "Cancel" button. Synchronizing with a computer other than your own or the one with which you normally perform this procedure causes the loss of all multimedia files on the device.

If you still can't find the button in question, go to the "View" menu, then choose the "Hide Sidebar" option.
- iTunes 10 and earlier: Look in the left sidebar for the "Devices" section. At this point, select the name of the device inside the latter.
Step 6. Search for your phone number
