Judging by past trends, the successor to the OnePlus 6 will not be seen until November but it is about time that OnePlus proceeds with the required worldwide certification and testing. A document recently issued by the Eurasian Economic Commission (EEC), which is headquartered in Moscow, has hinted that the OnePlus 6T is coming soon.

Even though the document doesn’t explicitly mention the OnePlus 6T, it is safe to assume that the ‘subscriber terminal’ mentioned in it is the successor to the OnePlus 6. The device goes by the model number A6013 and it is likely to be the European and North American quad-band version. The OnePlus 5 was referred to as A5000 and its successor, the OnePlus 5T was assigned the number A5010.
