Text Messaging Names Dont Show Up, only Phone Numbers? help

So I have this problem where when I get a text message even if the persons phone # is in my contacts the only thing that shows up is their phone number not their name? Is there any fix (besides the data plan) for this? thanks

Nope. I tried everything for this, adding the area code and parathesis and all those little secrets.

Data plan is the only solution.

You need to add the persons name & number in the address book before they text you, if however they do text you before that's done, you'll have to restart your Sidekick.

Data plan is only the whole 100% way ..sorry but to truely access everything on your sidekick you need it (I know its not what you want to hear)
