How to choose a proxy in Brazil: the checklist before you pay
The seven questions that separate a reliable proxy from a headache — IP origin, exclusivity, trial, support, and the fine print nobody reads.
The proxy market is full of similar promises and unequal delivery — and the cost of choosing wrong isn't just the money: it's the account that falls, the scrape that comes back distorted, the project that slips. This is the checklist we'd recommend even if you were buying from a competitor.
1. Where does the IP come from?
The most important question and the least answered on sales pages. Datacenter, resold residential, or mobile carrier — each origin gets classified differently by the sites you'll access (we wrote a full comparison of the three). Be suspicious of anyone who won't state the origin plainly: 'premium high-quality IP' is not an origin.
2. Genuinely dedicated, or a pool by another name?
'Dedicated' has a definition: only you use that address for the duration of the contract. If the pitch talks about 'millions of IPs', it's a pool — the model where the address's history is never yours. For accounts and sensitive operations, that's the difference between controlling your own reputation and inheriting everyone else's.
3. Can you test first?
A free trial or a published refund window is the mark of someone who trusts their own product. The right test: connect it to YOUR real tool (not just an IP checker) and run your actual use case long enough to see stability.
4. Is the price public and complete?
Price only by DM, or quotes by chat, usually means elastic pricing. And read the billing unit: per-GB looks cheap in the headline and gets expensive in real use if your operation consumes bandwidth; time-based with unlimited bandwidth flips that math. Project with YOUR volume before comparing numbers.
5. How does IP rotation work?
For accounts you want a stable IP with rotation under YOUR control; for scraping, programmable rotation. Check the service offers the mode your operation needs — and that rotating preserves host/port/credentials (otherwise every rotation becomes a reconfiguration).
6. Does support answer with actual humans?
A proxy is infrastructure — the day will come when you need someone. Send a real technical question BEFORE paying and time the response: pre-sales answer quality is the ceiling of post-sales support quality.
7. Does the fine print match your use?
- Acceptable use policy: is your use case allowed in writing?
- Hidden limits: 'unlimited' with an aggressive fair-use clause isn't unlimited.
- Renewal: automatic by default without notice, or under your control?
- Protocols: SOCKS5 and HTTP available (and switchable) cover any tool; a single one can box you in later.
Seven clear answers separate an infrastructure provider from a promise seller. And yes — we run this checklist on our own product: declared origin (Brazilian mobile carrier), dedicated by definition, 1-hour free trial, public pricing, IP rotation under your control, and human support.
