SMP vs iProxy.online: Singapore mobile proxy comparison for 2026

this comparison is for anyone evaluating mobile proxy vendors who has a specific reason to care about Singapore IPs: testing a SingPass integration, verifying ad placements in the SG market, running Shopee or Lazada price intelligence, or building a workflow that touches SG banking apps. it is also useful for teams currently using iProxy.online who are wondering whether there is something they are missing for SEA work. both products are real and both have legitimate use cases. the goal is to give you enough accurate information to make the right call for your situation, without reading five separate Reddit threads to get there.

TL;DR table

where iProxy.online is genuinely better

iProxy.online is a software platform, not a managed proxy service. if you already own phones and SIMs in multiple countries, it lets you turn those devices into proxy endpoints without buying into anyone else’s hardware fleet. for teams running operations in ten or fifteen countries who want to source their own local SIMs, that flexibility is genuinely valuable. you pick the carrier, you control the device, and you are not dependent on a provider’s hardware fleet being in the right place.

the per-phone pricing model also scales in a particular direction that suits certain use cases. if you need a large number of concurrent IPs across a broad geography and you have the operational capacity to procure and manage physical phones and SIM plans, iProxy.online’s model can be cheaper per IP than buying a managed service. the free port trial makes it easy to test the software before committing to anything.

for global multi-geo verification work where no single country is dominant, iProxy.online’s architecture gives you more control. you are not constrained by what a managed provider has deployed. if you need an IP in a market where no managed provider has hardware, BYO is sometimes the only answer. iProxy.online is a credible tool for that class of problem.

where SMP is genuinely better

SMP runs its own hardware: 100+ physical modems in Singapore on SingTel, StarHub, M1, and Vivifi connections. that is a meaningful structural difference from a software platform that requires you to supply your own devices. for teams that do not want to manage phone procurement, SIM contracts, device uptime, and firmware updates across a fleet, the managed model removes a significant operational burden. you get an endpoint; someone else handles the modem.

the carrier ASN purity argument is the more technically interesting one. every IP delivered by SMP resolves to a real Singapore mobile carrier ASN because it comes from a real Singapore mobile modem. there is no pooling with datacenter IPs, no residential-tier mixing, and no reseller intermediary that might introduce IP ranges from unexpected ASNs. for applications that fingerprint incoming connections at the ASN level (SingPass, DBS NetBanking, and most Grab merchant APIs do some version of this), the ability to guarantee a specific carrier ASN on every request matters. with a BYO platform like iProxy.online, ASN purity is entirely a function of which SIMs the operator chose to insert. if you do not control the SIM procurement, you do not control the ASN.

SMP also gives you direct sticky session control through a managed endpoint, which means session persistence is handled at the infrastructure layer rather than requiring you to configure and maintain it yourself. for workflows where session stability under a real SG mobile IP affects conversion or authentication success, having that baked into the endpoint rather than bolted onto a DIY stack is a practical advantage. the credential format (ip:port:username:password) integrates cleanly into any HTTP or SOCKS5 client without additional software.

the SG carrier IP question

Singapore has a small set of meaningful mobile carriers: SingTel, StarHub, M1, and Vivifi. each has its own ASN and its own IP ranges. applications built for the Singapore market often validate that a connection is coming from inside those ASNs, either explicitly (IP allowlist) or implicitly (risk scoring that penalizes non-mobile, non-SG-carrier traffic). this is particularly common in financial services, government digital services, and the larger e-commerce platforms.

SingPass is the clearest example. it is the national digital identity system and many SG government e-services sit behind it. testing SingPass integrations from a datacenter IP, a foreign residential pool, or an ASN that does not belong to a Singapore mobile carrier will produce different behavior than a real end-user on a real SG carrier plan. the same applies to banking apps from DBS, OCBC, and UOB, which run active device and network fingerprinting. if your test environment does not match a real SG mobile connection, your test results are not reliable signals about production behavior.

Grab merchant tools and Shopee SG are less strict, but they still do geo-validation and device consistency checks. ad verification for SG placements is another case where the specific carrier ASN matters: an ad network will serve different creatives to a SingTel mobile user versus a generic residential proxy, which means if your verification IP is not recognized as SG mobile, you are not seeing what your target audience sees. the verification result is only valid if the IP profile matches the user profile you are verifying for. this is explained in more detail in our post on ethical mobile proxy use.

iProxy.online is a BYO platform, so whether it can provide SG carrier IPs at all depends entirely on whether the operator deploying it has sourced and deployed SG SIMs on SG carrier plans. there is no SG infrastructure that comes with the product. if you are evaluating iProxy.online for SG work, you would need to either run your own SG phones or find a reseller who has done so. that introduces sourcing, logistics, and ongoing management complexity, plus ASN uncertainty unless you verify each SIM’s carrier assignment manually. for teams whose core use case is SG-specific, that operational overhead is hard to justify when managed SG hardware already exists.

pricing math at three realistic volumes

the two products have fundamentally different pricing models, so a direct per-GB comparison is awkward. SMP is a managed service where you pay for access to endpoints (by port count, bandwidth, or a combination). iProxy.online charges a monthly SaaS fee per phone port, but the actual cost of running a port includes the fee plus the cost of the phone hardware, SIM contract, and data plan, which the operator supplies separately.

the table below uses estimated all-in costs. iProxy.online figures are pricing snapshots as of 2026-05-14 and should be verified on their site before making a budget decision. SMP figures reflect current published plans at singaporemobileproxy.com. bandwidth cost assumptions for iProxy.online use a rough estimate of SGD 20-30/month per SIM for a mid-tier SG carrier data plan, but your actual cost depends on the plan you source.

a few things this table does not capture: SMP pricing includes hardware maintenance, uptime monitoring, and direct support. iProxy.online pricing does not include device replacement, SIM churning costs, or the time cost of managing a fleet. at light volumes, iProxy.online’s BYO model carries higher fixed setup costs relative to usage. at heavy volumes with existing phone infrastructure already in place, the SaaS fee can be competitive.

headline pricing on any proxy provider’s site rarely matches your actual bill. ask both vendors for a quote specific to your volume and use case before committing to either.

migration: if you’re switching from iProxy.online to SMP

if you have been running SG work through iProxy.online with your own SG SIMs and are moving to SMP’s managed endpoints, the practical steps are straightforward.

1. get your SMP credentials. after signup you will receive endpoints in the format ip:port:username:password for both HTTP and SOCKS5. SMP provides both sticky-session and rotating endpoints; pick the right one for your use case before you start migrating.

2. audit your current session stickiness settings. in iProxy.online you configure session persistence at the port level on your own device. in SMP, sticky sessions are handled at the endpoint level. map each iProxy.online port to either the SMP sticky or rotating endpoint depending on whether that workflow needs session continuity.

3. update your credential strings. this is usually a one-line change in your config or environment variables. see example below.

4. recalibrate rate limits. SMP modems are shared across your sessions but not overloaded. if you were running high concurrency against a single iProxy.online port on your own device, drop concurrency per IP and observe success rates for the first 24-48 hours before scaling back up.

5. A/B test before full cutover. run your existing iProxy.online endpoint and the new SMP endpoint in parallel on a subset of traffic for 24 hours. compare success rates, session stability, and ASN resolution (use a tool like curl -x with the endpoint and check the IP’s ASN via an IP lookup API). only cut over fully once the SMP endpoint is performing as expected.

# before: iProxy.online self-hosted endpoint
PROXY_URL = "http://your-device-ip:8080"  # no auth if local, or basic auth if configured

# after: SMP managed endpoint
# format: ip:port:username:password
SMP_HOST = "sg-sticky.singaporemobileproxy.com"
SMP_PORT = 10000  # your assigned port
SMP_USER = "your_username"
SMP_PASS = "your_password"

PROXY_URL = f"http://{SMP_USER}:{SMP_PASS}@{SMP_HOST}:{SMP_PORT}"

# for SOCKS5 (e.g. with httpx or requests[socks])
SOCKS5_PROXY_URL = f"socks5://{SMP_USER}:{SMP_PASS}@{SMP_HOST}:{SMP_PORT}"

1. verify ASN on the new endpoint. before running any SingPass or banking-adjacent tests, confirm the IP resolves to a SingTel, StarHub, M1, or Vivifi ASN. if it does not, contact SMP support to get a port pinned to the correct carrier for your use case.

bottom line

iProxy.online is the right tool when you want to run your own phones in your own locations and you have the operational capacity to manage that fleet. it is genuinely flexible, the BYO model gives you control over carrier selection, and the SaaS fee is reasonable for what you get. if your use case is global and you are not specifically anchored to Singapore, or if you already have phone infrastructure in place, iProxy.online is a credible and honest option.

for SG-specific work, the answer is different. SMP exists because the SG hardware exists: 100+ modems running on real SingTel, StarHub, M1, and Vivifi connections, managed and monitored, with carrier ASN purity on every IP. if your workflow touches SingPass, SG banking apps, Grab merchant tools, Shopee SG, or any platform that validates SG mobile carrier ASNs, you need IPs that actually come from those ASNs. that is not a marketing claim. it is a question of whether the infrastructure matches the test environment you need. iProxy.online does not ship SG hardware. SMP does. for SG-specific proxy needs, that is the deciding factor. check current pricing and port availability at the Singapore Mobile Proxy plans page, and if you are new to the underlying protocol differences, the HTTP vs SOCKS5 mobile proxies breakdown is a useful starting point before you configure your first endpoint.
