DUBAI, July 31 - Qatar Telecom
The former monopoly, which operates in 16 countries across the Middle East, Africa and Asia, had second-quarter net profit of 641 million riyals ($176.03 million) in the three months to June 30. That is down from 722 million riyals in the year-ago period.
One analyst forecast Qtel would have profit of 713 million riyals, in a Reuters poll.
Quarterly revenue was 8.4 billion riyals, up from 7.99 billion riyals last year. Half-year revenue was 16.4 billion riyals, up 6.1 percent.
"Net profit for the period was impacted by adverse foreign exchange movement in Indonesia and Algeria," Qtel said in a statement.

Qtel said half-year revenue at Indonesia unit Indosat rose in local currency terms, but fell 2.2 percent to 4.1 billion riyals.
Qtel's domestic operations had half-year revenue of 3.1 billion riyals, up 7.2 percent from a year ago.

"In Kuwait, the group saw an increase in competition during the second quarter, coupled with a decrease in SMS (text) revenues as customers begin to adopt messaging applications on smartphones," Qtel said on Tuesday.
Omani unit Nawras on Monday also blamed a move by customers to cheaper Internet-based call and text message services for a 3-percent drop in quarterly profit that missed estimates.
Iraqi unit Asiacell posted a 17.5 percent rise in half-year revenue to 3.3 billion riyals.
Qtel in June agreed a $1.47 billion deal to double its stake in Asiacell to 60 percent, while that month it also submitted an undisclosed bid for the remaining shares it does not own in Wataniya.
