The Department of Telecommunication’s wireless monitoring organisation has reportedly seized illegal network boosters in South and South-West Delhi which interfere with mobile services and result in call drops and other quality issues.

Moreover, the Wireless Monitoring Organisation (WMO) has issued notice to e-commerce companies warning against the sale of network boosters without valid permit, the official said.

Earlier telcos had lodged complaints with the DoT stating that illegal mobile boosters are interfering with their network causing frequent calls drops and hampering call connection etc.

According to industry estimates, there were reports of around 3,000 illegal boosters working in Delhi.

Earlier in 2019 too, the Wireless Planning Commission had issued notice to e-commerce for selling network boosters in an unauthorised manner.
