Earlier today we had reported that in a letter sent by the Cellular Operators’ Association of India (COAI) to the Telecom Regulatory Authority of India (TRAI), the latter had alleged that in independent testing by various telecom carriers in the country, devices with MediaTek SoC’s on board were causing Quality of Service (QoS) issues and throttling speeds on 4G networks.

Shortly after, we have been contacted by MediaTek India who want to dispel any misunderstanding that might arise from said story. Firstly they maintain that since being appraised of the situation their teams have been working on a solution. Once an appropriate solution would be found and approved, it would be shared by the company to its partners and then onto the customers.

On the point that the report alleges that it is an issue isolated to MediaTek SoC equipped devices, they stated that this is in-fact not a company specific issue since competing SoC’s by other companies were present in the devices tested and the COAI report shows that these also suffered reduced data rate issues when a second-SIM was inserted into the device.

Furthermore, on the point that MediaTek chipsets are present in more than 35% of the devices on the market which indicated that all these dual-SIM devices are causing QoS issue on networks, the company states that these issues are limited to India because of the number of networks present and lack of a single standard in India for such devices, quoting,

“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 officials further reiterate that they are “dedicated to meeting the full requirements from operators and would continue to work in cooperation with carriers and device makers to ensure dual-SIM devices in India operate to their optimal ability on all carrier networks and to meet future network advancements and standards.”

Seeing such a concise rebuttal, we have to wait and see how the situation develops. Rest assured that Devs Lab would be amongst the first to report on any improvements that arise out of this.
