Reliable mobile IP resolution APIs?

Hey everyone,

Still wrestling with the mobile network provider detection issue I mentioned in the previous thread. My current ISP lookup tool is just not cutting it for mobile traffic, especially when users are on the go or using various network setups. The main problem is accurately performing mobile IP resolution to identify the actual carrier. It often misidentifies or gives generic data center info, which isn't helpful for our analytics or targeted content.

I'm looking for recommendations for dedicated APIs or services that specialize in highly accurate mobile IP resolution. What are you guys using that reliably identifies mobile network providers, even with dynamic IPs or complex routing?

Help a brother out please...
