One of the biggest “problems” Western media identified on the Nokia 3310 (2017) were that the device was limited to 2 (. 5) G network. Fair criticism, but feature phones in general are aimed at markets where 2G won’t die for quite some time.
A Nokia 3G mobile device under the model number TA-1036 passed FCC, and the testing revealed that the device supports 3G bands (WCDMA Band 2 & 5, as well as GSM 850 & 1900MHz) that are supported by AT&T, Verizon, US Cellular and partially T-Mobile and Sprint.
The device could be a 3G version of Nokia 3310, and, as far as I know, the first device that supports 3G and runs Nokia S30+ OS. Maybe it will be announced at the upcoming event scheduled for 16th August.
