OK please help if you can... I am a newbie. There are a few questions below.
First I have a HTC 8525 on Cingular.
Here is what I would like to know and I am sure many others would too.
I would like to do what ever I need to do to prevent OTA internet/Data usage. I would like to only use wifi where available

. I do not need MMS at all *BUT* do need SMS messaging available always.
Here is what I do know, I can call *611 and have cingular CSR shut off data but they told me it would also kill messaging, whould that only be MMS or SMS also?
Do I understand the differences between MMS & SMS, is the difference that SMS is the same onld text messaging we have always had and MMS includes the ability to send pics and video with a text message therefore requiring data usage?
I was with Sprint for years with Treos, no data plan, always got text messaging, now with my new phone just want to have wifi access where available with no risk of a $500. bill and have no need to pay $40. more for a data package I will not benifit from.
How can I gurantee no chance of data usage but still receive SMS messaging?
Thank you in advance,
Kevin
