From April 1, telcos must meet a new set of indoor mobile coverage standards.

They must ensure among other things that there is mobile phone signal coverage - enough for subscribers to make a telephone call - in at least 85 per cent of an entire building. These rules apply to homes, offices and malls islandwide. Telcos may face fines of up to $50,000 if they fail to meet the standards.

Previously, this standard was applied only to areas accessible by the public, such as lobbies, basement-level foodcourts and carparks. Exceptions are made where building owners have refused to give access to mobile operators to set up 3G base stations in the buildings.
