Cellular Phone Forum / Providers / T-Mobile / May 2005How SIM card carries my phone book?
I switched my SIM to different new phone with the old SIM card, I can see all the phone numbers which I entered in old phone book?. I was wondered whether SIM card had any flash to store all these phone book?. Does SIM card remembers or the carries iotself stores these numbers over the Network?. For example if I switch to different carrier, then I am not sure whether aIA can use the same SIM card. Any idea?. Thanks. The SIM has memory and stores your phonebook info internally if you want it to. It does not store the numbers with the carrier. You can move the SIM to any other GSM phone. You cannot use the same SIM if you switch to another carrier since the SIM also contains the carrier info. A new SIM will be furnished by the new carrier. You can move the phonebook from the old SIM to the phone's internal memory then insert the new SIM and copy it from the phone's memory to the new SIM.

A SIM is just a form of "smart card" as was previously used to store pictures in some older digital cameras etc. and is what's used for some phone cards that have stored value on the cards. Same in principal as SD and MMS cards. Your name/number data is stored on the card so if you switch to a different handset all your information that you entered and saved to the card is there. If you switch to a different carrier if it's a GSM carrier they will have a new SIM card. The only way to have the information from your old card on the new one is to back up the information on your old card and transfer it to the new card. - - - - - - - - - - - - - - - - - - - - - - - - - - Thanks for info, appreciated. >I switched my SIM to different new phone with the old SIM card, I can >see all the phone numbers which I entered in old phone book?.
