Can prices change in the middle of a contract
<p>I am one of those people still clinging onto an AT&amp;T unlimited mobile data plan. Three months ago I signed a two-year contract to renew the plan. Today I got an email from AT&amp;T saying that my <a href="http://www.pcworld.com/article/3156592/mobile/att-raises-unlimited-data-pricing-as-carriers-push-users-away-from-grandfathered-plans.html" rel="nofollow noreferrer">data price would increase from $35 to $40 per month in March</a>.</p>

<p><a href="http://att.myscan.mobi/brochures/pdf/ATT_Family_Talk_Rate_Plans.pdf" rel="nofollow noreferrer">Here is a contract</a> I found for my plan.  Notice that it says, "Prices are subject to change." I assumed that meant that prices could change up to the point when we signed the contract, and that they would be locked in after that. AT&amp;T is offering to let me out of my contract with no penalty, but I just want them to honor the contract I assume we both signed.</p>

<p>Do I need to either pay the new price or exit the contract? Are those my only options?</p>

<p>Yes, prices can change in the middle of the contract if the contract says they can: yours does. The sentence "Prices are subject to change" means exactly what is says: prices can change.</p>

<p>Your belief that this applies to pre-contract prices only is wrong. In fact, contracts only deal with themselves - if a contract wants to deal with what happened before it existed it must specifically call this out.</p>
