T-Mobile Cellular Routing over IPv4 and IPv6 on iPhone

Currently, in Las Vegas, NV, while using T-Mobile as a cellular provider with NextDNS, frantech-las is being assigned for IPv4 and IPv6, but it is consistently slower than anexia-lax, vultr-lax, zepto-lax, and smarthost-las. Please route around the use of frantech.

As the information is from an iPhone, a Diag cannot be provided.

Thank you.
