The Cellular Operators Association of India (COAI) has reportedly written a letter to the government over MediaTek-based dual-SIM smartphones wherein flow of data in the primary 4G SIM slot is choked when a 4G LTE-only SIM is placed in the second slot. The industry body has reportedly asked the government to order smartphone companies to roll out an update to fix the problem. MediaTek, on the other hand, said it was working with the operators and investigating the matter.

The COAI in its letter to DoT and TRAI says that when using a 4G LTE-only SIM in the second slot significantly deteriorates the throughput of any other operator s 4G SIM present in the main slot by as much as 40 percent. The same, however, does not reoccur when the 4G LTE-only SIM is put in the first slot and 4G SIM in the second slot, reports ET. The problem mentioned only happens in MediaTek-based smartphones.

In simpler words, if you put a 4G LTE-only SIM in the secondary slot meant for 2G on your dual-SIM MediaTek-powered smartphone, you might get slower data speeds than what your telecom operators could be offering.

The analysis so far points to a chipset specific implementation by MediaTek. It is estimated that MediaTek chipsets are present in more than 35 percent of the smartphones in the country, the COAI said.
MediaTek, meanwhile, has assured of fixing the problem at the earliest. The Indian mobile market is a key focus and of great importance for MediaTek. We recently became aware of these reports and it is of the utmost priority to address. While MediaTek s solutions are globally compliant and fully adhere to all global standard bodies-defined guidelines, we are already working closely with all the telecom operators to ensure any reported issues are resolved, a MediaTek India representative said in a statement.
It is worth pointing out that MediaTek has a huge presence in the budget smartphone category, especially under Rs 10,000 segment. Counterpoint analyst Shobhit Srivastava says, MediaTek captured 28 percent market share for Dual-SIM LTE smartphone in CY 2016, in India. With increasing penetration of 4G LTE smartphones and network reach, smartphones with 2G SIM support (as SIM 2 or otherwise) are going to be obsolete.
Moreover, the COAI has urged the government to make sure such devices with 2G SIM slots are phased out from the market in the next six months. The body says dual SIMs must be compliant to 3G or 4G standards. It also asked the government to impose a ban on any mobile device that hampers data throughput. It also requested the government to make it mandatory for companies to conduct device testing and certification for compliance in accordance with the Indian environment before rolling out to the market.
