AT&T says Balloon Fiesta visitors nearly doubled their data usage from last year.
The company says customers used more than 12.5 terabytes of data.
That is the equivalent of posting more than 35 million balloon photos.
People used 6.3 terabytes of data at the event last year.
AT&T uses a “Cell on Wheels” to make sure emergency workers had signal and to make sure people could tweet and text pictures.
