Nokia Mobile is planning on announcing new Nokia phones, and the press pre-briefing is happening in India on August 25. There is a plan of announcing numerous smartphones and maybe even a 4G feature phone, and one of those phones just got certified in India. The new Nokia models that got listed on BIS in India are TA-1299, TA-1302, and TA-1304. Those model numbers are not seen before and could belong to just one phone, or each belongs to a variant of a phone dedicated to the Indian market. The new models were included in the certificate on August 11, which suggests many more are coming.
Nokia 5.3 is expected to launch in India soon, but with being in production for over six months, its model numbers are known already (TA-1234, TA-1227, TA-1223, and TA-1229). So those new numbers probably belong to different models like Nokia 6.3, or something else.
Anyway, that pre-briefing on August 25 will be interesting!
