Russian operator Mobile TeleSystems (MTS) has suspended any investments in the company's i-mode service until September because of lower-than-anticipated uptake. MTS launched a promotional campaign for the service in September 2005 and hoped to sign up more than 150,000 users in the first six months. The service supports about 100,000 users now, according to local press reports that say a shortage of compatible handsets has stunted growth of the NTT DoCoMo-developed technology. MTS launched i-mode in September last year, making it the 11th market to launch the service outside of Japan. Article
