You should receive a welcome kit, in which there will be information regarding your account, deposit slip, postage-prepaid envelop, etc. You can use the deposit slip to fund your account. Make a check payable to yourself, endorse it, and write down your account number on the memo line of the check and mail it to BOA using the postage-prepaid envelop.

Howeverm, I would set up transfer in BOA's website, making the transfer from another bank to BOA. That won't cost you anything.
