Unless purchased unlocked, all iPhones are locked to a specific carrier and only the carrier can release them. When? Depends on the carrier's policies, but usually after some mandatory period is over. Will have to check with your brother the status of the phone with respect to the carrier and if free will need to contact them to carry out the procedure for release. Only then will you be able to swap the SIM.
Also, since you will want to be independent of your brother, he'll have to disassociate the phone from his AppleID. See here for details: https://support.apple.com/en-us/HT201351
