Despite the potential to move further up the rankings, opportunities have been limited due to a lack of funds, and not enough ITF tournaments being played in Pakistan.

Aqeel Khan began playing tennis at the age of 9, whilst attending school in Karachi to avoid doing duties as a ball boy.

He turned pro in 1998 and played his first Davis Cup match in Islamabad, Pakistan, beating Sanjeev Tikaram of Pacific Oceania, 6–1, 6–3.

Also he played in the Davis Cup playoff against Chile in Santiago, when he was thrashed by then current Olympic medalist Fernando González 6–0, 6–0 6–1 in the first rubber.

He represented Pakistan at the Asian tennis championship in Tashkent, Uzbekistan, seeded sixth, but lost in the second round.

In 2008 Aqeel Khan was called up the Pakistan Davis Cup squad and prepared for the hectic Asia/Oceania Group III schedule.

During the Davis Cup, he was inspired form, as Pakistan won each tie 3–0 to gain promotion back to Asia/Oceania Group II.

He went to New Delhi, India to play in his first Challenger level tournament, however he was knocked out in both singles and doubles in the first round.

In 2011, Pakistan once again beat Hong Kong in the first round of the Davis Cup, but lost 4–0 to South Korea to remain in Group II.
