Pat Blashill of Rolling Stone referred to "Mobile" as a "completely inescapable hit". He noted that "Lavigne wails over crashing waves of acoustic and electric guitars, her big voice occasionally turns sideways in a drawl, a casual hint that she may actually be, of all things, a fine country singer in the making".^[2]

"Mobile" was solely released as a single in New Zealand and Australia. The song debuted at number 36 on the New Zealand Singles Chart for the issue dated May 11, 2003. It spent a total of 11 weeks on the chart, peaking at number 26 for the issue dated June 8, 2003.^[3]
