AustraliaMobile vs Residential vs Datacenter Proxies: Which Should You Use?
The real differences between mobile (4G/5G), residential and datacenter proxies — trust, speed, price and when each one makes sense.
Not all proxies are equal. The type of IP address you use decides how websites treat your traffic, how often you get blocked, and how much you pay. Here's how the three main types compare, and when each one is the right choice.
The short answer
| Datacenter | Residential | Mobile (4G/5G) | |
|---|---|---|---|
| IP comes from | Hosting companies | Home broadband ISPs | Mobile carriers (O2, EE, Verizon…) |
| Trust with websites | Low | Medium | Highest |
| Chance of being blocked | High | Medium | Low |
| Speed | Very fast | Varies | Good (4G/5G) |
| Price | Cheapest | Mid | Highest per IP |
If a site is easy-going, datacenter proxies are cheap and fast. If a site is strict — social networks, marketplaces, sneaker and ticket sites, search engines — mobile proxies are the most reliable option.
Datacenter proxies
Datacenter proxies use IP addresses owned by hosting and cloud companies. They're fast and cheap, but every website knows which IP ranges belong to data centres. Strict platforms block or challenge them on sight, because real customers almost never browse from a server.
Good for: bulk requests to lenient sites, speed tests, internal tools. Not good for: social media, marketplaces, anything with serious bot protection.
Residential proxies
Residential proxies route your traffic through IPs assigned to home broadband connections. They look like ordinary households, so they're trusted more than datacenter IPs.
The catch is that most residential proxies come from huge shared pools. The same IPs are used by many other customers, often for aggressive scraping, so many of them arrive already flagged. Quality varies a lot from one request to the next.
Good for: general scraping, price monitoring, geo-checks where some failures are acceptable.
Mobile proxies
Mobile proxies use IP addresses from mobile networks, through a real 4G or 5G modem with a SIM card. They're the most trusted type of IP on the internet, for one technical reason: CG-NAT.
Mobile carriers don't have enough IPv4 addresses for every phone, so they put many subscribers behind each public IP. At any moment, one mobile IP may be shared by a large number of real people. If a website blocks that IP, it blocks all of those genuine users too — so websites avoid blocking mobile IPs. (We explain this in detail in What is CG-NAT?.)
That makes mobile proxies the best choice for:
- Running multiple social media accounts (Instagram, TikTok, Facebook)
- Scraping sites with strong anti-bot protection
- Marketplaces and e-commerce
- Local SEO and rank tracking
Shared vs dedicated mobile proxies
Mobile proxies come in two flavours:
- Shared — you share a modem (and its IP) with other customers. Cheaper, but you inherit whatever they do with it.
- Dedicated — the modem and SIM are yours alone. The IP's reputation is entirely down to you, and you get the full bandwidth.
All ProProxies plans are dedicated: one modem, one SIM, one customer.
Which should you choose?
Ask two questions: how strict is the website, and how costly is a block? If a block costs you an account, a sale or a day's data, the extra cost of a dedicated mobile proxy is usually worth it.
