I picked up an ObiTalk box and nope, folk can't tell.
what happens when someone calls me if i am using a textnow app? are they able to tell its a textnow app, verses a regular company service? its kind of embarrassing for anyone to know i cant afford a real phone at the moment. also, if they do a google search using the textnow number, are they able to find out its a free texting app? thanks! (my teenager asked me to ask this)
