Why Hai Phong matters for app testing
The reason Hai Phong deserves dedicated attention is simple: geo-features, pricing and CDNs only reveal themselves to local IPs.

It balances success rate against cost for this exact use case; you can fall back to datacenter for easy targets, but the hard ones in Hai Phong, Vietnam demand residential-grade trust.

Validating app behaviour from different networks and regions. Mobile Proxies are the safest default here because they carry genuine trust, and a sticky session pattern fits this workload. Datacenter IPs work for lenient targets but fail fast on strict ones.

Residential traffic runs from about $0.80/GB at value networks like Cheapest Proxies up to $6/GB at legacy vendors; datacenter IPs can be under $1 each. Compare on cost per successful request — a cheap pool that fails often is more expensive in the end.
