text+ is the one i have for if/when i get too close to my 200 texts!
i believe it shows random numbers to the recipient, though (which in my case is always only hubby... so it doesn't matter!)
we tried a couple others and they weren't reliable (messaged didn't go through a lot of times) with text+ every one i sent went through quickly and he replies back to me (into text+ were just as quick!)
You can set it up to show your name. If I send A text to a non text plus user they see "text + Joe smith".
It also gets set up that when they respond it goes to my text plus account.
It has been very fast almost real time on wifi and 3g. Have not use it on the edge network.
I can answer more questions later when I'm not typing on the phone
