There are a couple of options. If you have IB and an iphone, you can get emini quotes with the IB app. If you have any WM phone, you can download MetaTrader4 Mobile demos from either Broco Forex or Windsor, both have live emini futures quotes.
Another option then is to use your phone's email address, it's received as SMS. http://www.makeuseof.com/tag/email-to-sms/
Forgot about quotetracker. They're pretty good. Your broker can problem do it. TOS has it i'm pretty sure as well as a host of others.
