there are only a small handful of taskbars that will not give you this icon.
unless the person who designed the taskbar adds a fix, i have not found a fix that can be added after the fact.
someone should start a post with a list of the ones they have found to work.

however, if you are on sprint and your hone did not come with a sim card, all you need to do is throw one in.
any sim card will work...i found a broken tmobile phone in the street, popped the sim out of it, threw it in my phone, set my phone to cdma only, and it fixes the problem.
