Buy IPv4 proxies that carry a real carrier address
Everyone shopping for an IPv4 proxy wants the same three things: accounts that stay alive, data that arrives without captchas, and a bill that does not double mid-month. What decides all three is not the port number or the dashboard — it is the origin of the address. IPv4 ranges issued by mobile operators to real SIM cards get the highest trust score of all proxy types, so the same script that used to die on request twenty runs to completion.
OnlineProxy sells mobile ports: every address belongs to a live cellular network, with a specific country, city and operator chosen before payment. That makes the decision to buy ipv4 proxies here a decision about survivability rather than volume — payment goes to the port, not to gigabytes burned on blocked attempts.
Why cheap ipv4 proxies end up being the expensive option
Bulk lists of cheap ipv4 proxies are almost always hosting ranges. They arrive with a fraud score in the 75–100 zone, they sit in blacklists already, and platforms classify them as automation before the first request lands. One burned advertising account with a warmed profile and a payment card costs more than months of honest ports — that is the real price tag hiding behind a low per-address rate.
Price per address is the wrong metric anyway. A single mobile port that keeps one account alive for a year beats a hundred discarded addresses, and the math becomes obvious the moment relaunch time is counted instead of line items.
| Proxy type | Address source | Typical fraud score | Ban risk |
|---|
| Datacenter | Hosting, cloud | 75–100 | High |
| Residential (other category) | Home ISP line | 25–50 | Medium |
| Mobile (our ports) | Cellular operator, real SIM | 0–15 | Minimal |
What a shared carrier address does for your accounts
Mobile operators place hundreds to thousands of subscribers behind one public IPv4 address — typically 500 to 5000 per address. Blocking it would cut off a crowd of paying customers, so platforms fall back on soft measures: a captcha, a rate limit, a slowdown. Your profile collects a warning where a hosting address would collect a permanent ban.
The second effect is rotation that looks like ordinary life. Cell handovers and reconnects reassign addresses all day long for regular subscribers, so an address change inside a session raises no flag — and long working sessions stop ending in endless re-verification loops.
Pro-tip: check every port before loading a profile into it. whoer.net, iphub.info and IPQualityScore should show a mobile ASN and a fraud score under 25. If a provider's "mobile" port resolves to hosting, that is a substitution, and no fingerprint tool will rescue the account afterwards.
Lite or Regular: match the plan to the task
Two plans, one billing logic — payment per port for 1, 7 or 30 days, unlimited traffic on both, and no per-gigabyte metering anywhere. Rates depend on country and operator and are shown on the plan page, so the real choice is how much control over the address the task needs.
| Parameter | Lite | Regular |
|---|
| Device access | Shared, up to 5 users | Dedicated for the whole rental |
| Rotation | Automatic every 2–5 min, not manageable | Sticky, by link, by timer |
| Device reboot | Unavailable | Available |
| Support | Standard | Priority |
Lite fits monitoring, position checks and short scraping runs where an address may change on its own. Regular is the working setup for account farms and ad campaigns: a dedicated device means the rotation schedule belongs to you, and one flagged neighbor no longer drags a whole profile down.
Rotation control is where the budget is saved
A sticky session holds the address while an account logs in, uploads creatives or passes verification. Rotation by link fits automation: the script calls one URL, receives a fresh address, continues without a restart. Timer rotation carries overnight campaigns unattended, so nothing stays on the same address long enough to trigger a rate limit.
Tasks where a mobile IPv4 port pays for itself
- Multi-accounting on Instagram, Facebook, TikTok, X and LinkedIn: one port, one antidetect profile, one account — mixing them is exactly what links a farm together.
- Scraping Google SERP, Amazon, Booking and flight data: where residential pools drop below 80% success, carrier addresses hold 95–99% on the same targets.
- SEO monitoring by city and operator, returning the real mobile SERP instead of a desktop approximation.
- Ad verification and cloaking checks: the creative is seen in the network where it is actually served, so fraud gets caught before the budget is gone.
- Limited drops and ticket releases, where fast rotation plus a trusted address decides who checks out first.
IPv4 or IPv6: ask before paying
Several carriers push subscribers onto IPv6, and a share of platforms, antidetect builds and older tools still handle it poorly — sessions break, geo lookups misfire, support tickets pile up. Staying on IPv4 keeps compatibility boring and predictable, which is the whole point of paying for infrastructure.
Protocols, authentication and integration
HTTP(S) covers browsers and most frameworks; SOCKS5 is mandatory for antidetect browsers and anything that needs UDP. Both authentication methods are available — login:password from any location, or whitelisting for a fixed office address. The API returns the current address, forces rotation and reports usage, so managing dozens of ports stays a script instead of a manual routine.
What the address does not fix
Network identity is one layer of four. Fingerprint isolation belongs to Multilogin, Dolphin Anty, AdsPower or Octo; human-like delays belong to your automation; language, timezone and currency must match the country of the port. Reliability comes from the full stack — mobile address, unique fingerprint, realistic behavior, geo consistency — and skipping one of them makes the other three pay for the mistake.
Billing, cashback and support
The minimum billing period is 24 hours, which turns a one-day port into an inexpensive way to test a target before scaling. After a paid rental ends, cashback is credited as promo funds on the internal balance; refunds follow the refund and replacement policy — in full within the first hour after access is issued, later minus the time used, and technical issues are answered with a replacement port first. Support works around the clock with a four-hour target for the first reply.
A free server proxy is available through the widget on the site for basic checks — that is a datacenter address, not a mobile one, and there is no free trial on mobile ports. Teams that buy ipv4 proxies for account work usually start with one Regular port per profile, confirm a week of clean operation, then scale port by port. Ready to buy ipv4 proxies with a specific operator and city? Pick the geo, take a port for a day, and let the accounts vote.
