An Indian anti-radiation organisation, Brightsandz, says prolonged use of dual SIM phones can cause radiation hazards like low sperm count and DNA damage.
A dual SIM mobile phone is one that holds two SIM cards. Devices that use more than two SIM cards have also been developed and released.

However, like all good things, the dual SIM mobile phone is seen to become a problem, as it also has an unaddressed issue of concern attached to it.
As networks and users grow, there also grows the lattice network of Electromagnetic Radiation – which may have serious effects on individual and public health, Brightsandz says it has discovered.
Brightsandz, an anti-radiation organisation offering radiation protection services, highlighted some dangers mostly ignored about the use of dual SIM phones.
Prolonged usage of dual SIM phones are associated with enhanced radiation hazards and has a significant double radiation effect, according to the organisation.
Brightsandz explains that mobile phones give out radio frequency radiation (RFR) when communicating with cell phone towers. While the physical effects of the radio radiation is negligible, doctors, public health specialists and many citizen groups believe that prolonged exposure to RFR can cause DNA damage, reduce sperm count, increase memory loss and risk of Alzheimer’s and even cause cancer.
Owing to the fact that there are two SIMs trying to reach out to two sets of towers, increases the radiation emission by double as compared to a single SIM phone, according to Brightsandz.
“Of the dual SIM devices that we have tested, we have seen an increase in radiation levels from 40% – 80% in most of the dual SIM phones, as compared to their single SIM counterpart. Therefore prolonged usage of dual SIM phones are associated with enhanced radiation hazards,” Brightsandz says.
Within dual SIM phones, there are two categories – Dual Active and Dual Standby. Dual Standby refers to a single radio unit that caters to both the SIMs and a Dual Active refers to a radio unit each for each of SIM (hence 2 radio units).
In a Dual Standby phone the radio is used by the two SIMs in turns – whereas in the Dual Active device both radios are working together. Therefore the total radiating energy of dual active devices will theoretically be two times of a single device, says the anti-radiation organisation.
Brightsandz admits that the scientific and social debate on the ill-effects of electromagnetic radiation is far from being resolved, but notes that one thing is clear and that is, “being surrounded with wireless devices with no protection, you may actually be risking your health and the health and well-being of others around you.”
For those who use a dual SIM phone, but activate one SIM and put the other in standby mode, Brightsandz says the extra radiation are not cutting out. The vacant SIM Radio is still latching to the available networks (which allows the user to call emergency numbers etc) – thereby increasing the radiation intensity. It may not be as high as loaded dual SIM devices – but it is still higher than a single SIM phone.
While Brightsandz is not against the use of dual SIM phones, it listed out some important things to note before a phone user buys a dual SIM phone.
- Think clearly – do you really need a dual SIM phone. Is your desk phone at home or office not good enough for office use?
- If at all you are buying a dual SIM phone, please indulge in purchasing from good brands, rather than unverified handsets.
- Please check the specific absorption rate (SAR) value of the phone that you are purchasing. Any SAR value higher than 1.6W/kg is not safe.
- Please do not carry your dual SIM phone in your trouser pocket. Use a belt clip for carrying your dual SIM phone. Use a radiation shielding phone pouch to reduce effect of RFR.
- If you are not using a particular SIM for a long time, switch off that SIM. Some dual SIM phones allow you to set individual SIM settings.
