The assertion that SIM card data indicates the presence of 27 million foreigners in South Africa, which is roughly half of the country’s population, has been publicly denied as untrue and based on a serious misunderstanding of telecoms data. The claim has been widely disseminated and has been generally disregarded.
According to the assertion, which quickly spread across various social media platforms, cell network statistics suggest an overwhelming number of individuals who are not citizens of the country who are currently residing there. On the other hand, specialists and analysts have made it clear that the data collected from SIM card registration cannot be utilised to determine nationality or the demographics of the individual population. The interpretation of datasets pertaining to telecommunications is usually incorrect, which results in findings that are overstated and misleading.
Specialists in the industry emphasise that the number of SIM cards reflects network activity rather than the number of unique users. A single individual may possess many SIM cards that are compatible with a variety of mobile networks, while other individuals may use SIM cards that are temporary, inactive, or only for data. It is also possible for roaming SIM cards belonging to international visitors, tourists, business travellers, and commuters who traverse international borders to be included in network databases without their being any indication of their citizenship or permanent resident status.
Furthermore, mobile network records frequently contain registrations that are either out of date or unverified, which further distorts raw results when used in isolation from their context. Rather than being used for the purpose of providing accurate demographic breakdowns, analysts emphasise that SIM data is designed for the purpose of network capacity planning and service delivery.
The use of raw telecoms numbers as a substitute for official census data has also been cautioned against by both the government and communications specialists. Population statistics are not generated from mobile subscriber counts, which are inherently fluid and subject to duplication, inactivity, and technological anomalies. Instead, population figures are derived from systematic national surveys.
As a result, the assertion that has gone viral has been deemed deceptive. Fact-checkers have pointed out that it significantly exaggerates assumptions by thinking that the existence of SIM cards is equivalent to the presence of specific foreign nationals. According to them, this misunderstanding has the effect of causing unwarranted confusion among the general public and distorting conversations about migration and demographic trends.
At a time when sensitive national problems are being discussed, the authorities have advised the general public to rely on statistics sources that have been validated. Despite the fact that migration and population dynamics are important topics of discussion, they must be based on correct data that is also methodologically sound, as they emphasise.
In conclusion, the allegation that data from SIM cards demonstrates the presence of 27 million foreigners in South Africa is not only unfounded but also scientifically flawed and not backed by any relevant demographic evidence.
