As evident from the name, the Galaxy A13 5G will support next-gen connectivity, unlike its predecessor which is limited to LTE networks.
The source doesn't reveal any specs of the Galaxy A13 5G but says the smartphone will have model code SM-A136B, and it could be priced under €200 as the Galaxy A12 is currently. This will make the upcoming phone the cheapest 5G phone in the Korean company's lineup.
We don't know when exactly Samsung will launch the Galaxy A13 5G, but since the Galaxy A12 was unveiled last November, we may see the A13 5G go official around the same time this year.
