SMP vs Shifter: Singapore mobile proxy comparison for 2026

if you’re evaluating proxy vendors for Singapore IPs specifically, or your SEA workflow depends on carrier-level attribution, most generic proxy reviews will point you in the wrong direction. they rank providers on global pool size and bandwidth price per GB, which is the right frame for most scraping work but misleads you when the target is SingPass, a Singapore bank portal, or a Shopee SG merchant dashboard that checks connection metadata. this comparison focuses on one narrow question: which provider actually delivers trustworthy Singapore mobile IPs, and when does the other one win anyway?

both providers are legitimate. Shifter has a real product with a real customer base. SMP’s differentiator is narrow but operationally significant: it runs its own hardware in Singapore on real carrier SIMs. that matters in specific situations and is irrelevant in others. this post tries to be clear about which is which.

TL;DR table

where Shifter is genuinely better

Shifter’s residential pool spans a large number of countries and cities. if your workflow touches multiple geographies at once (ad verification across US, UK, and DE alongside an occasional SG check, for example), Shifter can handle that from a single account and a single billing relationship. SMP does not offer non-SG IPs at all. a provider that does one thing does not win a multi-geo comparison, and there is no point pretending otherwise.

for teams that need formal SLAs and enterprise procurement infrastructure, Shifter is the more natural fit. SMP is a smaller, Singapore-focused operation. it can respond quickly and work through problems directly, but it cannot offer the same breadth of documented uptime guarantees and supplier contracts that enterprise procurement teams sometimes require as a precondition of vendor approval. if your legal or finance team needs a signed agreement with specific uptime commitments, that conversation will go more smoothly with a larger established vendor.

Shifter’s 3-day trial is also a practical advantage for teams doing exploratory evaluation. if you cannot commit budget without running a controlled test first, the self-serve trial removes that friction. SMP’s onboarding is more contact-based, which works well when you already know what you need but is a higher barrier for teams still deciding whether a mobile SG proxy fits their stack at all.

where SMP is genuinely better

the core SMP advantage is operational, not marketing: the modems are physically in Singapore, registered to real Singapore carrier SIM cards on SingTel, StarHub, M1, and Vivifi. when a target system resolves an incoming IP, it lands on the correct mobile ASN because that is where the traffic actually originates. there is no VPN tunnel to another country, no residential relay, no intermediary that could introduce ASN ambiguity. for targets that inspect ASN origin, and Singapore banking and government services often do this, the difference is not marginal.

session stickiness on SMP is user-controlled, which matters for workflows that require maintaining authenticated state across multiple requests. you select the endpoint, and the session stays on that modem until you release it. some port-based rotation systems rotate on each connection or on a fixed timer, which creates problems for multi-step authentication flows like those on SingPass or the DBS/OCBC/UOB internet banking portals. holding a sticky session to a known carrier IP is a functional requirement for those targets, not a preference. the HTTP vs SOCKS5 mobile proxies breakdown covers how protocol choice interacts with session handling if that is relevant to your stack.

because SMP runs a finite pool of 100+ real devices rather than hundreds of thousands of residential IPs, concurrency per IP is lower. that is a throughput limitation, but it is also an advantage for fingerprint stability. the IP is not simultaneously shared across many other customers, which means its reputation history is cleaner and its behavioral signature is less noisy. for automation that gets fingerprinted on traffic patterns rather than on IP reputation alone, that lower concurrency is meaningful.

the SG carrier IP question

Singapore’s high-value digital targets use layered anti-fraud and bot detection. SingPass (the national digital identity system, backed by the National Digital Identity infrastructure) evaluates connection metadata during authentication. DBS, OCBC, and UOB have significantly upgraded fraud detection in recent years, and those systems look at ASN, connection type (mobile vs residential vs hosting), and geographic consistency of the connecting IP. Shopee SG and Lazada SG fingerprint seller accounts partly on connection metadata. regional ad verification workflows that need to see Singapore ad slots accurately must originate from IPs that resolve to SG mobile carriers, not from IPs that happen to be geolocated to Singapore on a commercial geolocation database.

what “resolves to SG mobile carrier” means in practice involves the BGP routing system. every IP block is registered and announced via the Border Gateway Protocol under an Autonomous System Number. APNIC’s routing security resources explain how ASN attribution works at the regional registry level for Asia-Pacific. SingTel’s mobile IPs are announced under their mobile ASN. StarHub and M1 have their own. when a detection system queries the ASN for an incoming IP and sees a Singapore mobile carrier ASN, it classifies the connection differently than it would a data centre ASN, a residential ISP ASN, or an ASN registered outside Singapore. ASN purity means the IP resolves to the correct carrier ASN with no ambiguity about origin.

Shifter’s SEA residential pool includes some Singapore IPs, but the residential proxy model sources IPs from end-user devices, often via an SDK embedded in consumer apps. the ASN for those IPs reflects whatever ISP the device uses. that might be Singtel home broadband, which sits on a different ASN from Singtel mobile. it might be a smaller local ISP. it might be a user who has since relocated. the IPs rotate through a pool and are not guaranteed to resolve to mobile ASNs on a specific carrier in a specific country. for most proxy use cases that is perfectly fine. for SG-specific carrier-dependent targets, it is a structural constraint of the residential pool model, not a product failure.

the Cloudflare bot score documentation describes how signals including ASN type and IP reputation feed into bot classification decisions. the same principles apply to custom detection layers at banks and e-commerce platforms: a connection from a mobile carrier ASN scores differently from one originating from a residential or hosting ASN, and the gap is not trivial when the target actively filters on it. for a broader introduction to how mobile proxies work at a technical level, that post covers the underlying mechanics of SIM-based versus residential approaches.

the phrase “SG presence” also deserves some scrutiny. geolocation databases (MaxMind, ip-api, ipinfo) report what they have been told or inferred; they can be wrong, and they can lag behind IP reassignments. ASN lookups via BGP data sources (like those published by the Internet Assigned Numbers Authority) are more authoritative. a detection system at a Singapore bank is more likely doing ASN-level checks than relying on a commercial geolocation DB. “Singapore IP” on a geolocation report and “Singapore mobile carrier ASN” on a BGP lookup are not the same thing, and conflating them is how teams end up surprised when their proxy IPs get blocked on SG-specific targets.

pricing math at three realistic volumes

proxy pricing is genuinely difficult to compare because headline numbers rarely reflect real bills once you account for overage rates, concurrent connection limits, and what counts against bandwidth quotas. the table below is a good-faith orientation. Shifter pricing is a snapshot as of 2026-05-21 and should be verified directly on their site before any budget decision. SMP pricing should be checked at Singapore Mobile Proxy plans as rates depend on volume and configuration.

a few honest notes on what the table does not capture:

SMP’s pricing reflects the cost of running real hardware in Singapore on carrier SIMs. you are paying for a physical device on a mobile network, not a fractional share of a large pooled IP network. at low volumes the per-GB cost is likely higher than residential alternatives. at medium volumes the tradeoff depends on your success rate on actual targets. failed requests from mismatched IPs are not free: they cost bandwidth, time, and retry logic, and on SG-specific targets those failures can be frequent with a non-carrier IP.

Shifter’s port-based pricing is predictable for teams that can estimate port usage. if the use case is high-volume scraping where any SG or SEA IP works (not a specific carrier), Shifter’s model may be more cost-efficient at scale, particularly for teams already on the platform for other geographies.

neither provider gives you a clean linear price curve at scale. the only way to get a real cost comparison is to test your actual target URLs, measure success rates, and calculate cost per successful request rather than cost per GB.

migration: if you’re switching from Shifter to SMP

if you have been using Shifter and are moving to SMP for SG-specific work, the operational changes are modest. the credential format and endpoint structure differ, but the proxy protocol (HTTP or SOCKS5) is the same on both sides.

1. Get your SMP credentials. SMP uses the format host:port:username:password. you will receive the host, port, username, and password from SMP on account activation. there is no separate API key layer.

2. Update your proxy configuration. replace the Shifter endpoint and credentials in your client code or config file. below is a Python example using the requests library, showing both the old and new configuration side by side:

import requests

# previous configuration (Shifter-style, port-based rotation)
shifter_proxy = {
    "http":  "http://username:password@gate.shifter.io:port",
    "https": "http://username:password@gate.shifter.io:port",
}

# new configuration (SMP sticky session example)
smp_proxy = {
    "http":  "http://smp_user:smp_pass@sg1.singaporemobileproxy.com:port",
    "https": "http://smp_user:smp_pass@sg1.singaporemobileproxy.com:port",
}

# swap the dict reference; the rest of the request code is unchanged
response = requests.get(
    "https://target.example.com",
    proxies=smp_proxy,
    timeout=15,
)

1. Map session stickiness. if you were using Shifter’s rotation-on-connect model for stateless scraping, SMP’s rotating endpoint behaves similarly. if you need sticky sessions for authenticated flows, use SMP’s sticky endpoint and hold the connection for the full duration of the authenticated session. do not mix sticky and rotating endpoints within the same login session.

2. Recalibrate concurrency. SMP’s pool is smaller and more concentrated than a large residential network. start at lower concurrency than you ran on Shifter and increase after observing error rates. a reasonable starting point is half your previous concurrency ceiling, then step up in increments.

3. A/B test before full cutover. run the same request set against both providers in parallel for at least 24-48 hours. compare success rates, response times, and block rates on your actual target URLs. only cut over fully when SMP numbers are satisfactory for your specific targets. this matters especially if the target does session-level fingerprinting, because mixing providers mid-session can trigger anomaly detection.

4. Update any IP whitelists. if your target requires you to whitelist source IPs, SMP’s IP ranges differ from Shifter’s. obtain the current SMP IP list from their support team and submit it to the target before switching live traffic.

the credential format change is the main mechanical task. everything downstream (retry logic, session management, timeout handling) should transfer without modification if the code was written against a standard proxy interface.

for teams running mobile UI automation alongside proxy access, cloudf.one Singapore cloud Android phones is worth evaluating as a complementary layer, particularly for workflows that need both a real device fingerprint and a real SG carrier IP on the same connection. the combination of a cloud Android instance and a SIM-backed proxy is more convincing to fingerprinting systems than either tool alone.

bottom line

Shifter is the right call when you need broad geographic coverage, a large residential IP pool, enterprise contract infrastructure, or a self-serve trial before committing budget. it is a legitimate product with real customers across many industries, and for workflows that are not specifically dependent on Singapore carrier ASNs it competes effectively on volume and price.

SMP is the right call when the target is a Singapore-specific system that inspects ASN, connection type, or carrier identity. the hardware is in Singapore, on real SingTel, StarHub, M1, and Vivifi SIM cards. that is the operational basis of the product, not a claim layered on top of a resold pool. for SingPass automation, Singapore banking portals, Shopee SG or Lazada SG merchant tooling, or regional ad verification that specifically requires SG mobile carrier IPs, SMP is the structurally correct choice because the IPs originate where the target expects them to originate. please also read the ethical mobile proxy use guidelines before deploying either provider in any workflow touching consumer accounts or regulated services. view Singapore Mobile Proxy plans for current pricing or reach out to sales for a volume estimate tailored to your use case.
