If your mobile banking is merely a phone-phriendly (should it be fone-friendly?) version of your online banking, I think you can tweak your online disclosures a bit to include mobile access and consider them one service. But if mobile is appreciably different, or if there are different limits or restrictions that apply, I think you need to keep them separate for clarity's sake and provide a separate set of targeted disclosures when a customer signs up for mobile.
