Every business must build its own mobile community! Your mobile community is composed of everyone you know: your current clients, former clients and prospects. Also include vendors, friends, colleagues, rainmakers, networkers & connectors. Contact these people and ask them directly if you can have their mobile numbers. The worst they can do is to say no. If they say yes, what a great way to expand your relationship! So long as they stand to benefit from your messages, they can be bonafide members of your mobile community.
