Last week, the Cellular Operators Association of India (COAI) wrote a letter to the government on a 4G-related issue on MediaTek-powered smartphones. MediaTek acknowledged the issue, but says that the issue is also present on smartphones powered by other chipset makers. Nonetheless, the chipmaker says that it has developed a solution, which is currently being tested along with mobile operators before it can be rolled to the public.

The issue in question was regarding dual-SIM smartphones powered by MediaTek processors. In essence, when a 4G LTE-only SIM card was inserted into the second slot, there was a drop in data speeds by as much as 40 percent. The issue was however not visible when a 4G LTE-only SIM card was inserted into the first SIM, or a standard 4G SIM was inserted into the second slot.

MediaTek has responded to this issue saying that it is doing all it can to address the concerns and situation. It further added, Since being made aware of the dual-SIM issue, MediaTek teams designed a solution. The software optimization will improve network performance and is now being tested by MediaTek with mobile operators. Once the solution is fully tested and approved – expected in the upcoming days – it will be shared with customers to resolve network concerns.
But at the same time, the chipmaker clarified that This is not a MediaTek specific issue. Several of the devices listed by COAI were based on competitor chipsets and were not MediaTek powered devices.
It also says that this issue with dual-SIM smartphones is limited to the Indian market. It s partly due to the fast growing and maturing networks being rolled out and the fact each network has its own requirements for SIM cards. Currently, there is no single standard in India for dual-SIM devices and no over-arching requirement under the 3GPP standards which MediaTek complies with. Carriers provide their own SIM card requirements for their networks and share those with chipset makers. SIM requirements across 2G, 3G, 4G and 4GLTE networks in India have led to some unintentional compatibility challenges for the industry to address, MediaTek says via a statement.
With the entry of Reliance Jio, 4G is a buzz word in India and incumbent operators have been doing their best to offer 4G services at affordable prices. Smartphone companies too are cashing in on the trend by launching affordable 4G-enabled smartphones, and MediaTek for one has a huge presence in this segment. 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, Counterpoint Research analyst Shobhit Srivastava said.
