In June 2009, three major Chinese carriers—China Mobile, China Telecom and China Unicom—imposed limits on text messaging in order to crack down on spam SMS. Under the restrictions, a phone number can send no more than 200 messages per hour and 1000/day on weekdays.[27][28] In the United States, recipients of SMS spam can file a complaint with the FCC using form 1088G.[29] Phone users in the United Kingdom can use the Information Commissioner's complaints page and can take action against the sender through the small claims court.
