Well, officially, the answer is No. If your service provider does not support MMS, you will not be able to obtain MMS service.
You can try to find a different network to use, but most carriers that own MMSCs will only allow their own paid subscribers access to their MMSC. This makes sense... since they won't get paid for your use of their server.
You may want to check the press releases to see when/if your carrier will be providing this service. Many carriers (who haven't already) will begin to provide MMS service this year.
