Also posted at HoFo but there are no replies so let's see... AT&T With Texting Deactivated, what happens when somebody sends a Text? I have AT&T and I have been having some problems with texting overuse so I called AT&T and had them deactivate texting. I can no longer send or receive a text but what happens when someone tries to text me from another carrier (Sprint)? Do they get a "failure message" like with e-mail? Does the text stay in their "queue" and does the network attempt to send it again? For a test I composed and "sent" a text today and my Android Captivate said nothing was amiss - should it have told me that texting was not available and to call AT&T (or another message like that)?
Most of the time, if some one sends a text message to a phone that has text blocked, the sender will not get a notice that the message wasn't sent and the sender is charged appropriately. You won't receive a message since you have it blocked; however, AT&T MAY send out an administrative text, but these mesages will say "AT&T FREE TEXT" or something similar. But I wouldn't expect an administrative message because some one sent me a message. On your end, there shouldn't be a notice to you if you "sent" a message from a blocked phone... perhaps, in the outbox, there may be an icon saying the message wasn't sent.
I can only speak for what happens with T-Mobile. If someone sends a text and the they don't have texting enabled their message will be returned with a message that blocking is active (no charge message.) If someone has "filtered" their account to not receive any text messages the message will just drop off into the ether with no indication that it was received.
I've also disabled text messages on my line, and I've tested with other phones what happens when someone tries to text me. I don't ever get the message of course, and nothing happens on the senders end. It's like they're sending it to nowhere, as it never reaches it's destination, kinda like dead mail. So if the sender is unaware the person that they're texting can't get messages, they may get upset while waiting forever for a reply. Guess they better use the phone to call them instead!
Interesting! I always preferred phone calls to texting, but I never really got into the habit of it because I thought it was too expensive for the AT&T plan. However, disabling seems a little extreme because of how companies are beginning to implement the technology and even schools! Although it is counterproductive sometimes.
