Restricted signals aimed at stopping customers from mistakenly roaming onto foreign networks.
In a bid to prevent mobile users from mistakenly roaming onto foreign networks, Thailand and Laos have been told to restrict phone signals along the border between both countries.
The restrictions were imposed after stronger signals from networks in Laos began to overwhelm weaker signals from Thailand along the border. Subsequently, residents in Thailand were being charged for calls made on Laos networks.
In order to tackle the problem, both Thailand and Laos regulators implemented a policy, which limits phone signals in such a way that they do not infringe upon the other country by more than one kilometre in urban areas and two kilometres in rural areas.
Prawit Leesatapornwongsa, NBTC Commissioner, stated: "The limits of the signal level for Lao mobile phone users transmitting across the border are weak, so mobile phones in Thailand will not be automatically switched (to receive the signal from Laos)."
