Wireless connectivity is where these two phones begin to separate. Both support 5G, Bluetooth 5.3, NFC, and dual-SIM — a solid shared foundation. The A56 5G, however, adds Wi-Fi 6 (802.11ax) to its wireless stack, while the A17 5G tops out at Wi-Fi 5. On a compatible router, Wi-Fi 6 delivers lower latency, better performance in congested environments (like apartments or offices with many connected devices), and more efficient battery use during wireless activity. The A56 5G also pulls ahead on cellular throughput, with a maximum download speed of 5100 Mbits/s versus 2550 Mbits/s on the A17 5G — double the peak downlink capacity, which matters on modern 5G networks capable of delivering those speeds.
SIM flexibility is another point of divergence. The A56 5G supports 2 physical SIMs plus 2 eSIMs, whereas the A17 5G is limited to 2 physical SIMs only. The addition of eSIM support gives the A56 5G significantly more versatility for travelers, users managing work and personal lines, or those switching carriers without needing a physical card. On the flip side, the A17 5G includes a microSD card slot for expandable storage — a feature the A56 5G drops entirely. For users who rely on cheap external storage to bulk up capacity, this is a genuine trade-off to consider.
The A56 5G holds the broader connectivity edge thanks to Wi-Fi 6, faster cellular speeds, and eSIM support. The A17 5G's expandable storage slot is a meaningful consolation for storage-conscious users, but it is outweighed by the A56 5G's advantages across wireless performance and SIM flexibility.
