Sim card hold contacts, so pretty much everything will remain on your phone besides your contacs and your MEID which is your phone number.
SIM cards are the heart of a cellular phone, containing the phoneâs number, carrier designation, rate plan, address book, security codes, and more. SIM cards are only used in GSM-enabled phones. SIM cards can be moved from phone to phone within the same carrier. Some users may opt to purchase a prepaid SIM card to avoid the necessity of signing a long-term contract with a carrier.
