The WP55 Ultra pulls ahead on wireless connectivity across the board. It supports 5G while the A5 Pro 4G is limited to 4G — a meaningful long-term consideration as 5G networks continue to expand globally. It also adds Wi-Fi 6 (802.11ax) to its supported standards, whereas the A5 Pro 4G tops out at Wi-Fi 5. Wi-Fi 6 delivers faster throughput, lower latency, and better performance in congested environments like offices or public spaces. Its Bluetooth 5.2 is also a step ahead of the A5 Pro 4G's Bluetooth 5.0, offering incremental improvements in connection stability and audio streaming efficiency.
Two other WP55 Ultra advantages stand out. It includes a microSD card slot for expandable storage — something the A5 Pro 4G lacks entirely — which is particularly useful given the large media files that high-resolution cameras tend to generate. Its peak download speed of 2770 Mbps also edges out the A5 Pro 4G's 2500 Mbps, though both figures are fast enough that real-world differences will rarely be felt on current networks.
On shared ground, both phones offer dual SIM, NFC, USB Type-C, fingerprint scanning, GPS with Galileo support, and identical USB 2.0 speeds — so the fundamentals are well covered by either device. Still, the Oukitel WP55 Ultra holds a clear overall edge in this category, with its 5G support, Wi-Fi 6, newer Bluetooth, and expandable storage collectively representing a more future-ready and flexible connectivity package than the Oppo A5 Pro 4G.
