Guys, be careful with this. I was on the 10 GB mobile share when i heard about the double data promo. I upgraded to the 15GB and voila had the 30GB for the price of 15 (for an extra $30 a month for jumping from 10 to 15)
realized it was way more than i needed and heard about them doubling the 10GB plan to 20GB for the price of the 10. Also read here about the promotion being extended to middle of november.
call this morning to change to 20GB for the price of my old 10GB plan.... oh but wouldn't you f'n know... conveniently that ended last week (att rep with their stupid ass fake concerned voice)
so I'm still on 30gb for 15gb price, but i could be saving an extra $30 a month really. If anyone has success in trying to do what i am could you please post it here.
**they also told me the only thing that has been extended was the 30gb for price of 15gb...
I believe the only way to get the 10GB plan doubled to 20GB for the price of the original 10GB is to call AT&T Retentions Department, not regular Customer Service.
