According to the latest intel, AT&T will soon be increasing some of their fees as well as adding new ones to their services. First, starting August 1st, AT&T plans to raise the activation fee for one- and two-year contracts from $40 to $45. This will now be the highest activation fee amongst all the US carriers. AT&T has something even more irritating planned than that small price increase though. Any customer who signs up for the AT&T Next service on or after August 1st will have to pay a $15 activation fee. Previously, AT&T's Next Plan was an upgrade-when-you-want installment plan that lets consumers get started with $0 down and no hidden activation, financing, or upgrade fees. It looks like AT&T thought they were leaving free money on the tablet, so they are changing that. The same $15 rate applies even if you bring your own compatible smartphone from a different carrier for a new, contract-free line of service with the carrier. Anyone who already has the Next plan or who signs up before August 1st will not have this $15 fee. This move should make T-Mobile's CEO happy as it gives him extra ammunition.
