If you're going to buy proxies to resell, your supplier is your business. IP quality, per-GB economics, and the API behind your storefront decide your margin and your churn. Here's exactly what to look for in a wholesale mobile proxy supplier — and how to spot the ones that'll burn you.
The best wholesale mobile proxies to resell come from a supplier with real 4G/5G IPs, transparent per-GB pricing with volume tiers, a gateway you connect to (not hardware you manage), and an API to mint usage-capped customer keys — with no reseller deposit. PROXIES.SX fits: $4/GB dropping to $2.40 at volume, free endpoints, no monthly fees, GB that never expire, and an open-source kit to ship your store.
When you resell proxies, you never touch the IPs — but your customers feel them on day one. If the pool gets blocked on the targets they care about, they churn and they refund. So the single most important thing in a wholesale supplier is where the IPs actually come from. This is the difference between a 92% success rate and a flood of support tickets.
The trust hierarchy is simple. Mobile IPs sit behind carrier-grade NAT (CGNAT) — one IP is shared by thousands of real phones, so anti-bot systems can't block it without collateral damage to genuine subscribers. That's why mobile survives the hardest targets. Residential is one real home per IP: good trust, cheaper, but more individually blockable. Datacenter is ASN-flagged and trivially fingerprinted — fine for some jobs, fatal if a supplier blends it into a "mobile" pool and sells it to you as premium.
IPs sit behind carrier-grade NAT (CGNAT) shared by thousands of real phones. Blocking one means risking real subscribers, so anti-bot systems tread carefully. Best for the hardest targets.
Real home ISP IPs. Cheaper than mobile and fine for lighter scraping, geo-verification, and price monitoring — but more individually blockable than a shared mobile IP.
Cheap and fast, but ASN-flagged and easy to fingerprint. Reselling these as "premium" is the fastest route to refunds and churn. Avoid suppliers who blend these into a "mobile" pool.
The practical move for a reseller: source mobile + residential from one supplier so you can serve both hard and light use cases. PROXIES.SX runs real 4G/5G mobile and a residential pool (expanding now) across 17+ countries — one gateway, the right IP for each customer.
Everything in reselling is the spread between what you pay and what you charge. The wholesale rate — and how it falls at volume — sets your floor.
As a directional industry range, mobile bandwidth tends to sell wholesale around $2–15/GB and residential around $1–8/GB, with large swings by supplier and volume. Treat those as orientation, not quotes. What matters is your own cost basis and how it improves as you grow. Here's the PROXIES.SX wholesale ladder — the actual numbers you'd build your retail pricing on:
| Volume tier | Roughly | Your wholesale cost |
|---|---|---|
| List price | Entry volume | $4.00/GB |
| Tier 2 | Growing volume | $3.60/GB |
| Tier 3 | Mid volume | $3.20/GB |
| Tier 4 | High volume | $2.80/GB |
| Tier 5 | Top volume | $2.40/GB |
Two structural details make this ladder reseller-friendly. First, endpoints are free — no per-port or per-IP charges, no monthly minimums — so a small customer is still profitable and you don't carry fixed overhead between sales. Second, GB never expire: bandwidth you buy at a low tier doesn't evaporate at month-end, so your effective cost is exactly the rate you paid, not the rate minus waste. Suppliers with expiring bandwidth and stacked port fees quietly raise your real cost basis well above their headline number.
Industry ranges are directional and vary widely by provider, network, and volume — not quotes. Model your margin on your own confirmed wholesale rate.
There are two ways to be in the mobile proxy business. You can buy modems and SIMs and run the fleet yourself — capex, carrier plans, rotation rigs, uptime, and babysitting IP bans — for a pool that's capped at whatever hardware you own. Or you can resell on a gateway: connect to a single endpoint, and the supplier runs the physical layer. For a reseller, the gateway model removes the highest-risk, lowest-margin part of the business and lets you scale capacity on demand instead of buying boxes.
One endpoint — gw.proxies.sx:7000. No hardware, no SIM plans, no rotation infra. Scale on demand, pay per GB, and put 100% of your effort into branding, pricing, and support.
Modems, SIMs, racks, and uptime are your problem. Capex up front, a fixed pool you can't grow quickly, and constant maintenance — all before you've made a single sale.
If a wholesale supplier is missing any of these, you're importing their limitations into your business.
You need to create per-customer keys with GB caps and expiry programmatically — on every sale, automatically.
Per-port charges and monthly minimums silently eat your margin and make small customers unprofitable.
One supplier, one gateway, multiple networks — so you can serve more use cases without a second contract.
Geo-targeting is half of why customers buy. Look for genuine multi-country reach (PROXIES.SX: 17+ countries).
Pay for the GB you use. Avoid suppliers who gate reseller access behind large upfront deposits.
An MIT-licensed kit (SDK + dashboard + storefront) means you ship in an afternoon instead of building billing from scratch.
The API point is the one most resellers underrate. You need to mint per-customer keys with GB caps and expiry on every sale, automatically — otherwise fulfilment needs a human and you can't scale. The PROXIES.SX reseller API does exactly this, and the MIT-licensed proxy-reseller-kit ships the SDK, a customer dashboard, and a storefront on top of it.
Mandatory reseller deposit before you can mint a single key — your capital is locked up before you earn a cent.
Opaque, "contact sales" pricing with no published per-GB rate or volume tiers — you cannot model your margin.
No API, only a manual dashboard — you cannot automate fulfilment, so every sale needs a human.
Datacenter IPs sold as "mobile" — high block rates show up as refunds and churn within days.
Per-port or per-IP monthly fees stacked on top of bandwidth — small customers become unprofitable.
Bandwidth that expires monthly — unused GB you already paid for evaporates, crushing your effective cost.
The deposit one is worth dwelling on: some suppliers gate reseller access behind a large upfront deposit, which locks your working capital before you've proven a single sale and ties you to them even if the IP quality disappoints. The reseller-friendly model is the opposite — pay only for the GB you use, mint your first key in minutes, and grow into the volume tiers as your customers do. That's the model PROXIES.SX runs: no deposit, published per-GB pricing, free endpoints, and a single gateway with a real API behind it.
Wholesale mobile proxies are 4G/5G mobile IP bandwidth bought at a discounted per-GB rate so you can resell access to your own customers. Instead of running modems and SIMs yourself, you buy capacity from a supplier — at PROXIES.SX that is $4/GB on the list price, dropping to $2.40/GB at volume — and sell it on at your own markup. Free endpoints, no monthly fees, and GB that never expire keep your cost basis simple.
Pricing is per-GB and varies by network. As a directional industry range, mobile proxy bandwidth tends to run roughly $2–15/GB and residential roughly $1–8/GB, with big swings by supplier and volume. PROXIES.SX wholesale starts at $4/GB and falls to $2.40/GB at the highest volume tier, with no per-port charges, no monthly minimums, and bandwidth that does not expire.
Five things decide your margin and churn: IP quality (real mobile/residential, not recycled datacenter), transparent per-GB pricing with volume tiers, a gateway you connect to instead of hardware you manage, an API to mint usage-capped customer keys, and no reseller deposit lock-in. Avoid suppliers with opaque pricing, mandatory deposits, or no programmatic key control.
Both, ideally from one supplier. Mobile (4G/5G) IPs sit behind carrier-grade NAT shared by thousands of real subscribers, so they carry the highest trust and survive aggressive anti-bot systems — best for hard targets. Residential is cheaper and fine for lighter scraping and geo-checks. Reselling both from a single gateway lets you serve more use cases without juggling two suppliers.
A gateway means you connect to one endpoint (PROXIES.SX uses gw.proxies.sx:7000) and the supplier runs the physical 4G/5G fleet, rotation, and uptime. Buying modems means capex, SIM plans, IP-ban babysitting, and a fixed pool you cannot scale on demand. For a reseller, the gateway model removes the highest-risk, lowest-margin part of the business.
Real 4G/5G mobile + residential across 17+ countries. $4/GB → $2.40 at volume, free endpoints, no monthly fees, GB that never expire. No reseller deposit. One gateway, one API, an open-source kit to ship your store.
