HMD’s most recently announced device, the Nokia 3310 (2017) 3G, went through the Bluetooth certification process. The certification didn’t reveal much that we don’t already know, but it showed the model numbers for the 3310 with 3G.
The TA-1022 is Nokia 3G Single SIM with dual band support (or more precise: Dual band 900/1800 MHz +3G Band 1 and 8). The TA-1006 is Dual SIM version with the same dual band support as the TA-1022. And we have the TA-1036, which is Single SIM and Quad Band support, or as Nokia says on the official website: (Single-SIM) Quad band GSM 850/900/1800/1900 + 3G Band 1, 2, 5, 8. Bluetooth on all variants is BT2.1.
