Why Sao Paulo matters for app testing
The reason Sao Paulo deserves dedicated attention is simple: geo-features, pricing and CDNs only reveal themselves to local IPs. Layer on its status as Latin America’s e-commerce giant, and generic global pools that work elsewhere start returning partial or misleading results for app testing.
Best proxy type for app testing
For app testing, we recommend Mobile Proxies as the default in Sao Paulo, Brazil. They give you the trust profile this workload needs, and a sticky session strategy suits how app testing traffic behaves. Datacenter IPs are cheaper but get flagged faster on the strict targets app testing usually involves.
