SMP vs Proxyrack: Singapore mobile proxy comparison for 2026

This comparison is for teams already evaluating proxy vendors and specifically needing Singapore IPs or workflows anchored in Southeast Asia. If you’re price-shopping for a global residential pool and Singapore is one of fifty geos, you probably want a different article. But if SingPass, Singapore banking, Grab merchant tooling, Shopee SG, or Lazada SG sits anywhere in your workflow, the carrier-level detail below matters more than any headline plan comparison. Both Singapore Mobile Proxy and Proxyrack are real products with real customers. The goal here is simple: put the relevant differences on the table so you can make the call.

TL;DR table

where Proxyrack is genuinely better

If your work spans a dozen countries and Singapore is one entry in a long list, Proxyrack is the more practical choice. Their global P2P pool gives geographic coverage that a single-country hardware operator can’t match. Spinning up IPs in the US, UK, Germany, Japan, and Brazil from one dashboard, one billing relationship, is genuinely useful for distributed ad verification, global SERP monitoring, or ecommerce price intelligence across many markets at once.

Proxyrack’s unlimited threads plus bandwidth model suits high-concurrency scraping jobs where you’re optimizing for raw throughput across a large pool. If you’re running thousands of concurrent threads against targets that aren’t carrier-sensitive, spreading that load over enough dedicated mobile ports on a hardware provider will likely cost significantly more for the same job. P2P residential pools are built for volume in a way that physical modem operators just aren’t.

Proxyrack’s trial is self-serve, so you can test the global pool without a sales conversation. That matters for individual researchers and small teams who need to validate fit before any procurement cycle. SMP’s trial is self-serve too (24 hours, 10 GB, no card), so for Singapore-only testing this one is a draw.

where SMP is genuinely better

SMP runs its own modems in Singapore. Not a marketing claim, a structural fact with measurable consequences. When you resolve an SMP IP, it returns an ASN belonging to Singtel or M1 because the traffic is actually leaving a SIM card on that carrier’s network. No intermediate residential P2P node, no relayed peer, no datacenter hop dressed up as mobile. For targets that check the ASN of the connecting IP against a list of known mobile carrier blocks, this is the difference between a successful request and a blocked one.

Sticky session behavior on physical hardware is also qualitatively different from sticky sessions in a P2P pool. With SMP, a sticky session means your requests route through one specific modem for the duration of the session. The IP may change when the carrier rotates it, but the device doesn’t. That consistency matters for workflows that maintain session state across multiple requests, like authenticated shopping carts, account dashboards, or any flow where the server fingerprints the connection over several round trips. In a P2P pool, “sticky” means you’re re-routed to the same peer node, but that node’s carrier assignment, latency, and uptime are outside the operator’s control.

SMP’s concurrency-per-IP ratio is lower by design. Each modem handles a small number of concurrent connections, which keeps the per-IP request signature close to what a real SG mobile user would generate. That fingerprint fidelity is what lets it pass carrier-level checks that P2P residential pools, even good ones, struggle with consistently.

the SG carrier IP question

Singapore’s major consumer-facing digital services use multi-layered fraud signals to decide whether to surface full functionality, flag a session for step-up authentication, or silently degrade the experience for suspected non-resident traffic. Understanding how a mobile proxy fits into that detection stack is necessary before choosing a provider for this market.

The ASN (autonomous system number) of your connecting IP is one of the cleaner signals these systems have available. SingTel operates AS7473, StarHub runs AS9506, M1 is on AS38322, and Vivifi has its own block. These are well-known to Singapore’s major platforms. When DBS, OCBC, or UOB’s fraud layer checks the ASN of an incoming session, it’s cross-referencing against exactly these known blocks. An IP that resolves to a residential ISP, a datacenter, or a foreign peer-to-peer pool fails that check regardless of how the session cookie is constructed.

Proxyrack is a P2P residential network. In Singapore, that means peer nodes are devices on home broadband connections. The ASN for those devices is typically Singtel Fibre or StarHub Cable, not a mobile carrier ASN. Some peer nodes may sit on mobile data connections, but the pool doesn’t provide ASN-level guarantees by carrier. For targets that aren’t inspecting at the ASN level, this distinction is invisible. For targets that are, it’s decisive.

SingPass authentication is the canonical example. SingPass doesn’t block proxies categorically, but it’s sensitive to session signals that don’t cohere with a real Singapore resident. A session arriving on a known SG mobile carrier ASN, with a realistic user-agent and consistent geolocation, is far less likely to trigger friction than one arriving from a pooled residential node of uncertain origin. Grab’s merchant dashboard and Shopee SG’s seller tools both have rate-limiting logic that’s more permissive toward known mobile carrier ranges. Engineers report meaningfully different success rates depending on whether the IP resolves to a real mobile carrier block.

Regional ad verification for the SG market has the same dependency. If you’re verifying that an ad campaign is serving correctly to SG mobile users on specific carriers, the verification client needs to present an IP that matches the carrier it’s simulating. Verifying a SingTel mobile ad placement from a StarHub home broadband IP is testing a different audience segment. Verifying from a P2P peer in an unspecified location is testing almost nothing.

pricing math at three realistic volumes

Proxy pricing has more variables than most providers advertise. The Proxyrack numbers below are estimates based on publicly observable pricing structures as of 2026-05-17; SMP numbers are list prices. Verify both providers’ current rates directly before committing: SMP at singaporemobileproxy.com and Proxyrack at proxyrack.com. Proxyrack pricing snapshot taken 2026-05-17, subject to change.

Mobile hardware operators price differently from P2P pool operators, so a like-for-like comparison isn’t fully possible. The table below maps to three realistic monthly bandwidth volumes for SG-focused work.

A few things these numbers can’t capture. Proxyrack’s unlimited threads model can look cheap on paper and expensive in practice if you hit undocumented rate limits or IP quality degradation at high concurrency. SMP’s price is a flat fee per port with a fixed data allowance, so the list price is what you pay. Neither provider’s headline rate accounts for the engineering cost of retry logic when IPs fail quality checks on the target side. If your job requires high success rates on carrier-sensitive targets, the effective cost per successful request favors SMP even further.

On these figures SMP’s $40 port is already at or below Proxyrack’s range at 10 GB, and at 100-500 GB a flat $40 or $50 port is well under it. Where Proxyrack pulls ahead is very high volume across many ports or many countries, so run the numbers against your actual thread count and success rate before deciding.

migration: if you’re switching from Proxyrack to SMP

If you’ve decided to test SMP alongside an existing Proxyrack setup, the practical steps are straightforward. The credential format and endpoint structure are different enough to require code changes, but nothing is architecturally complex.

1. get your SMP credentials. SMP uses host:port:username:password format. Your SMP dashboard will show the endpoint host, the port (HTTP and SOCKS5 are separate ports), and the per-session username and password. Note which port is for sticky session and which is for rotating.

2. map your rotation model. If you were using Proxyrack’s rotating pool, use SMP’s rotating endpoint. If you were using Proxyrack sticky sessions, switch to SMP’s sticky endpoint and decide on session duration. SMP sticky sessions hold a session to one modem rather than one peer node, so the behavior is slightly different under IP rotation events.

3. update your proxy configuration. The change is usually one block in your configuration. Here is a Python example using requests, assuming you are migrating from a generic rotating residential format to SMP:

import requests

# before: Proxyrack rotating residential
proxyrack_proxy = {
    "http":  "http://username:password@proxy.proxyrack.net:9000",
    "https": "http://username:password@proxy.proxyrack.net:9000",
}

# after: SMP rotating mobile (HTTP)
# replace host, port, username, password with values from your SMP dashboard
smp_proxy = {
    "http":  "http://smp_user:smp_pass@sg.singaporemobileproxy.com:8080",
    "https": "http://smp_user:smp_pass@sg.singaporemobileproxy.com:8080",
}

# for SOCKS5 (see /blog/http-vs-socks5-mobile-proxies for protocol choice guidance)
import socks
import socket
# socks.set_default_proxy(socks.SOCKS5, "sg.singaporemobileproxy.com", 1080, username="smp_user", password="smp_pass")

response = requests.get("https://api.ipify.org?format=json", proxies=smp_proxy, timeout=10)
print(response.json())

1. recalibrate rate limits. SMP endpoints sit on physical modems with real carrier rate limits. If you were hammering a P2P pool with 50+ concurrent threads, reduce concurrency significantly during testing. A good starting point is 3-5 concurrent connections per modem. Check with SMP support for the per-endpoint concurrency ceiling.

2. A/B test before full cutover. Run both endpoints in parallel against a sample of your target URLs for at least 48 hours. Log success rates, response times, and IP change frequency separately. The goal is to confirm that SMP’s carrier ASN is actually helping your specific target before you shut down the Proxyrack account.

3. update any IP allowlisting. If your target requires IP allowlisting (less common with mobile proxies but relevant for some enterprise APIs), request SMP’s current IP range list and submit it alongside your existing allowlist before cutting over.

bottom line

Proxyrack is the right choice when your work is geographically distributed, you need high thread counts across a large residential pool, and Singapore isn’t a special-case requirement. Their self-serve model, global coverage, and unlimited bandwidth plans are genuinely suited for scraping at scale across many markets. Building infrastructure for global ad verification or multi-country price intelligence? Start there.

SMP is the right choice when Singapore is the primary market and the target is carrier-sensitive. The physical modems, the real Singtel and M1 ASNs, and the sticky session model that pins to a real device are not features a P2P pool can replicate at the ASN level. For SingPass workflows, Singapore banking and financial apps, Grab and Shopee seller tooling, or any use case where the SG carrier IP is load-bearing, SMP exists specifically for that gap.
