The installation of base stations in Khasa has allowed Nepalis to use Chinese mobile phones in the border area near the Friendship Bridge. Living in a place that is out of reach of mobile network signals, many Nepalis are using Chinese sim cards. Similarly, Nepalis in the western tarai regions of Bhairawa, Taulihawa, Krishna Nagar and Butwal are using Indian mobile systems. Many hundreds of thousands of rupees are flooding to India as Nepali customers switch to Indian telephony because of the delay in Nepal Telecom's resumption of services. There are an estimated 5,000 Nepali subscribers of the Indian private operator Hutch. In the Universal College and Teaching Hospital in Bhairawa alone, there are said to be more than 200 Hutch phones in use. Instead of cracking down on this illegal use, Nepali security forces reportedly make up the majority of Indian mobile users.
