AT&T has two new short-term data plans for tablet users — $5 for 250MB in a day, or $25 for 1GB over three months. These are in addition to the $10 a month customers pay to add a tablet to a shared plan. [9t05Mac]
Don't know about your plan..but MOSt smart phones require Full access, and data is in that plan. should be 5gig minimum..and if you paid for unlimited..($50-80 per month) why would you need this.
If you have an OLD phone that sucks on the net? EMAIL?? hope you don't get much spam as HTML code tends to be filled with crap.
