Coverage
Our Sri Lanka RDD sample connects with 24 million individuals for your research.
In Sri Lanka, the use of mobile phones has become increasingly popular in recent years. According to the Telecommunications Regulatory Commission of Sri Lanka, the number of mobile phone subscribers in the country has surpassed 30 million, with a penetration rate of over 140%. This high mobile penetration rate indicates that mobile phones are more frequently used than landline numbers in Sri Lanka. The convenience and affordability of mobile phones have contributed to their widespread adoption in the country. Additionally, the expansion of mobile networks and the availability of various service providers offering competitive packages have further fueled the popularity of mobile phones among Sri Lankans. While landline numbers are still used in Sri Lanka, particularly in households and businesses, their usage has significantly declined in comparison to mobile phones. Many people prefer the flexibility and portability that mobile phones offer, allowing them to stay connected wherever they go. Overall, it is clear that mobile phones are the preferred mode of communication in Sri Lanka, as evidenced by the high mobile penetration rate and the widespread use of mobile phones across the country.
