If I change my mobile phone card from one mobile phone to another, can I see the information in that mobile phone on the other mobile phone?

If the information in your mobile phone is saved on the card, you can still see the previous information on another mobile phone after changing the card, including the phone book, text messages and so on! Otherwise, you can't see it!

SIM card is an IC card held by mobile users of GSM system, which is called subscriber identity card. GSM system identifies GSM users through SIM card. The same SIM card can be used on different mobile phones. GSM mobile phone can only be used in the network after inserting SIM card.

SIM card is the key for GSM mobile phone to connect to GSM network. Once the SIM card is removed from the mobile phone, the mobile phone will not be able to enjoy all kinds of services provided by network operators except emergency calls. SIM card can not only be used as a key, but also provide a lot of convenience for users. Users only need to insert or embed the SIM card into any GSM terminal to realize communication. SIM card also manages a lot of information provided to users, which can be used to store short messages, especially those received when users are away or absent.
