• Tiers above 1,000 GB are on the page's Enterprise tab and are bought through the same checkout; beyond 10 TB it's sales only.
• The help docs put the residential pool at 55+ million IPs; the product page says 120M+.
• Unlimited Residential is sold by speed and days (from $1,425 for 100 Mbps for 30 days) and isn't listed here.

• Same prices as residential; the checkout labels it 'mobile proxies - beta'. The docs describe it as an experimental mode of the residential setup, with a fixed list of locations: US (random, Texas, New York, Florida), UK (London) and Austria (Vienna), and no carrier choice.

• Billed monthly; the docs say auto-renewal isn't supported.
