how to tressing a phone by it's sim card number in online
Yes. The sim card is what gives the phone its number.
A sim card is a chip in your phone that holds information as to your phones identity such as your phone number. A sim card can be transferred to another phone allowing you to have to same phone number as well as your contacts.
The Phone Number is assigned to the SIM card. If you put the SIM card into the new phone, the number will be the same, However not all SIM cards wil transfer to all phones.
The old SIM card will still be programmed with the original phone number. Either SIM will work in the phone - unless the old SIM is blocked by the network when they issued the new one.
No, you should not sell your SIM card. You can sell your phone without SIM card. SIM card identifies you and your phone number registered with the mobile service provider. **Some one can misuse it. If you no longer need it, confirm that all the services linked with your SIM card and old phone number are deactivated and then destroy it. - Neeraj Sharma
