SMP vs SOAX: Singapore mobile proxy comparison for 2026

This comparison is for engineers and ops teams where Singapore IPs are a hard requirement, not a preference. If you are building automation that touches SingPass, DBS or OCBC banking flows, Grab merchant tooling, Shopee SG, or Lazada SG, the carrier fingerprint of your proxy IP matters in ways it does not for general-purpose scraping. This post covers where SOAX and Singapore Mobile Proxy (SMP) actually differ, prices both at three realistic volume tiers, and gives a straight answer about which provider fits which job. Neither is universally better. The honest answer depends on your geo mix and your tolerance for carrier-level detection.

TL;DR table

where SOAX is genuinely better

SOAX covers more than 190 countries with a pool they report at over 8.5 million residential and mobile IPs globally. If your scraping targets are spread across the EU, US, LATAM, and Southeast Asia at the same time, managing that geo mix through a single SOAX account with their dashboard is genuinely more convenient than stitching together multiple regional providers. The product is mature, the dashboard is clean, and the session controls work reliably at scale.

Their $1.99 / 24-hour trial is one of the lowest-friction evaluation paths in the industry. You can spin up a test, point your scraper at it, and get a real signal on success rates within an afternoon. That matters operationally, especially when you are evaluating multiple vendors in parallel and do not want to get on a sales call before you have seen a packet.

SOAX also has a scraping API layer (a managed endpoint product) that abstracts away proxy rotation, retries, and JavaScript rendering. For teams that do not want to own proxy orchestration logic, that managed layer can meaningfully reduce engineering overhead. If your use case is commodity web scraping at high volume across multiple geographies, SOAX is a reasonable choice and the per-GB pricing is competitive at scale.

where SMP is genuinely better

SMP operates its own physical modems inside Singapore, on SingTel, StarHub, M1, and Vivifi SIM cards. That is not a marketing statement; it is a network topology fact with measurable consequences. Every IP that SMP routes exits from a real SG mobile carrier ASN. The rDNS, the WHOIS, the BGP path, the latency from SG datacenters, all of it resolves consistently because the hardware is in Singapore. This matters for targets that do carrier-level or ASN-level checks, which is common for financial, government, and logistics platforms in the region.

Because SMP runs a fixed number of modems rather than drawing from a rotating pool of millions of nodes, the IP-to-concurrency ratio is lower. Fewer sessions share each exit IP at any given time. For workflows where fingerprint consistency matters across a session (a multi-step checkout, a logged-in merchant dashboard, a banking OTP flow), low IP sharing significantly reduces mid-session detection risk. Sticky sessions work because the modem itself holds state, not because session-ID cookies are mapped back to a pool entry.

The credential format (ip:port:username:password) is straightforward and works with every standard HTTP and SOCKS5 client without middleware. You get both protocols from the same endpoint, and you can map specific ports to sticky sessions without any dashboard configuration. For teams that want to keep proxy logic in code rather than in a web UI, that is a practical advantage. See our HTTP vs SOCKS5 mobile proxies guide for the protocol-level differences.

the SG carrier IP question

Singapore-specific platforms have built strong signal libraries for detecting non-local traffic over the last several years. The mechanics vary by platform, but three checks appear consistently: ASN ownership (is this IP block registered to a SG mobile carrier?), latency fingerprinting (does round-trip time from the IP to SG infrastructure match what a local mobile device would produce?), and behavioral clustering (does this IP show the session patterns of a real SG subscriber?). Platforms like SingPass and the major SG banks have regulatory incentives to enforce these checks strictly, because they are required to verify that users are physically in Singapore for certain transaction types.

A residential IP from a pooled global provider can be technically located in Singapore in the MaxMind or IP2Location databases without being a SG mobile carrier IP. The ASN might resolve to a hosting provider, a CDN edge node, or a residential broadband block rather than a mobile carrier block. For most scraping targets this is irrelevant. For SG financial and government platforms it frequently triggers additional friction: CAPTCHA escalation, OTP loops, session invalidation. Teams that have burned hours debugging why a Singapore-geolocated proxy still fails SingPass verification are usually hitting this exact issue.

SOAX’s SEA pool, to be precise about what we know, is not published at the carrier-ASN level. SOAX does not claim to operate its own hardware in Singapore. Their mobile IPs in the region come through peer network agreements, which is the standard model for large residential/mobile aggregators. This is not a deceptive practice; it is how the industry works at global scale. The structural consequence is that you cannot verify which SG carrier ASN an exit IP will resolve to before you make the request, and you have limited control over staying on a specific carrier across a session.

For workflows that do not depend on SG-specific targets, this distinction is immaterial. If you are scraping global e-commerce price data and Singapore is one of thirty geo targets, carrier-purity in SG is not a meaningful selection criterion. But for any workflow where the target actively checks SG mobile carrier provenance (Grab merchant login, Shopee SG seller tools, banking MFA flows, certain SingPass API integrations), the ASN matters and the difference between a real SingTel exit IP and a pooled IP that geolocates to Singapore is the difference between success and a blocked session. Understanding what counts as ethical mobile proxy use in these contexts is worth reading before you go live.

pricing math at three realistic volumes

Pricing in the proxy industry has enough plan variants and add-ons that headline numbers rarely match real invoices. The estimates below use publicly available or representative pricing as of 2026-05-11. Verify current rates on each provider’s site before committing. SOAX pricing in particular changes frequently with promotional tiers.

SOAX pricing snapshot (verify at soax.com, as of 2026-05-11):

SOAX bills by GB consumed. Starter tiers run approximately $6-9 per GB. Volume tiers drop to roughly $3-4 per GB at 100 GB/month and approximately $2-3 per GB at 500 GB/month for mobile IP access. Actual rates depend on whether you use residential or mobile endpoints and which subscription tier you are on.

SMP pricing:

SMP is port/session-based rather than GB-metered. You pay for concurrent sessions or modem access rather than for bytes. This model is meaningfully different for bandwidth-heavy workflows. Check current plans at Singapore Mobile Proxy.

The crossover point where SMP’s port-based pricing beats SOAX’s GB pricing depends on how much bandwidth you pull per session. If you are doing lightweight API calls or AJAX requests, GB consumption is low and the SOAX model can be cost-competitive. If you are loading full pages, downloading media, or running browser-based automation, GB adds up fast and a flat port-rate model becomes substantially cheaper. Run the math against your actual traffic profile.

One cost that rarely shows up in comparison posts: failed request retry overhead. If your success rate is lower due to non-carrier IPs on carrier-sensitive targets, you are paying for GB that produce no usable data. That invisible cost can flip the pricing comparison entirely for SG-specific work.

migration: if you’re switching from SOAX to SMP

If you have existing automation running on SOAX and are moving it to SMP for SG-specific targets, the migration is straightforward. The credential format changes, the session model maps cleanly, and the main calibration work is around rate limits and retry logic.

1. get your SMP credentials from the dashboard or account setup email. you will receive a host, port, username, and password per endpoint or per modem allocation.

2. update the proxy string format. SOAX uses a gateway + session-ID model. SMP uses a direct ip:port:user:pass format. update every place in your code that constructs the proxy string.

# SOAX format (example, your actual gate/port may differ)
SOAX_PROXY = "gate.soax.com:9000"
SOAX_AUTH = ("customer-XXXXX-sessionid-abc123", "your_password")

# SMP format
SMP_HOST = "your.smp.endpoint"   # from your SMP dashboard
SMP_PORT = 10000                  # port maps to a specific modem/sticky session
SMP_USER = "your_username"
SMP_PASS = "your_password"

# requests library (both HTTP and SOCKS5 work)
import requests

proxy_url = f"socks5://{SMP_USER}:{SMP_PASS}@{SMP_HOST}:{SMP_PORT}"
# or for HTTP:
# proxy_url = f"http://{SMP_USER}:{SMP_PASS}@{SMP_HOST}:{SMP_PORT}"

proxies = {"http": proxy_url, "https": proxy_url}
response = requests.get("https://target.example.com", proxies=proxies, timeout=15)

1. map sticky sessions. if your SOAX workflow relied on session-ID-based stickiness, map those to specific SMP ports. each port corresponds to a modem, so the sticky session is hardware-level rather than session-cookie-level. you get stronger stickiness, but you need to plan port allocation ahead of time for concurrent session counts.

2. recalibrate rate limits. SOAX’s large pool means you can typically hit higher concurrent request rates per “session” because the pool handles distribution. SMP’s modem-based model means each port is one physical IP. adjust concurrency per port downward if you were previously sending high parallel request volumes through a single SOAX session endpoint. two to five concurrent requests per modem port is a reasonable starting point for most targets.

3. A/B test before full cutover. run 10-20% of your SG-targeted traffic through SMP for 48 hours while keeping SOAX active. compare success rates, latency, and error types. if SMP success rates are materially higher on your SG targets (which is the expected outcome for carrier-sensitive endpoints), complete the migration. if your targets are not carrier-sensitive, the difference will be smaller and the decision comes down to cost.

bottom line

SOAX is a competent, well-maintained proxy provider with a genuine product. For teams running global scraping operations across many geos, their residential pool, their scraping API layer, and their volume pricing make them a reasonable choice. The $1.99 trial removes friction from evaluation, and the dashboard is usable without a learning curve. If Singapore is just one of many geo targets and your SG-specific targets do not check carrier provenance, SOAX can cover that geo adequately.

For work that specifically requires Singapore mobile carrier IPs, SMP is the right call because the SG hardware exists and SOAX’s does not. That is the whole argument, stated plainly. If your automation needs to present as a SingTel or StarHub subscriber to a target that checks ASN provenance at the BGP level, a reseller pool that geolocates to Singapore is not the same thing as a modem running a SingTel SIM in a Singapore rack. SMP’s 100+ live modems are the only way to get that guarantee from a commercial proxy provider. For SG financial platforms, government integrations, and major SG e-commerce and logistics tools, that guarantee is worth paying for.
