Lock down 'receive text messages' setting I recently got a shock on my phone bill when it showed over a hundred texts received by the standard text messaging app. I had been receiving these solely through Google Voice, specifically to avoid such charges.

I checked the Google Voice settings, and somehow the 'Receive text messages' setting had been switched to 'Via the messaging app'. Ack! I switched it back. But: Is there a way (or a utility app) that will lock this setting in place?

[EDIT] All right, I was a bit vague in the original description of this problem. Let me walk through this step by step:

Last month, my phone bill was about $25 more than the month before. Comparing it to the previous bill, I found that the difference was due to over 100 texts having been received on the phone through the carrier.

I checked my phone settings, and found that in Google Voice, the setting under Sync and Notifications >> Receive Text Messages was set to Via the messaging app. All the recent text messages were listed in the standard messaging app. I changed the Google Voice setting to Via the Google Voice app, and had a friend send me a new text message. It appeared in Google Voice, but not in the standard messaging app.

What I seek is a way to lock down that Google Voice setting so that it cannot be changed. (I suspect that it was altered somehow by a recent Google Voice upgrade.) Does such an app exist, or is there a way of doing this that I am overlooking?

Thanks...

If you don't want to receive text messages on your actual phone number and only receive them via your Google Voice number, just call your carrier and tell them to disable text messaging. 

I used to do that, back when I had a plan that charged for messages. Just tell them to disable incoming and outgoing text messages, and you won't have to worry about any future charges.

The Google Voice app sends and receives text messages as standard data, and it doesn't use the carrier's texting abilities. So disabling texting through your carrier won't inhibit your ability to use Google Voice for texting.
