Category: Mobile Proxy Use Cases

Singtel mobile traffic leaves on AS7473. M1 is AS17547. StarHub’s mobile network is AS9874. I checked all three against RIPE before writing this, because two of the numbers I have seen printed in other Singapore proxy guides belong to a Malaysian carrier and an Australian wholesaler, and the people repeating them clearly never looked.

That is the level most Singapore proxy advice sits at. So here is what a Singapore mobile proxy actually is, what it is genuinely good for, where it bites, and how I would set one up in 2026. I run a mobile proxy farm here, so this is from operating the things rather than from a vendor comparison table.

What the term actually means

A mobile proxy routes your traffic out through a device on a cellular network. Not a server in a Singapore data centre. A modem or a handset with a physical SIM, registered to a carrier, getting its address from that carrier’s pool the same way a phone in someone’s pocket does.

The distinction that matters is the autonomous system. When a site looks up the address you arrived from, it gets an ASN and a type. AS7473 comes back as Singtel, classified cellular. A Singapore VPS comes back as a hosting provider, and every risk engine worth the name treats those two as different populations of user.

Geolocation is the layer people check. It is also the layer that tells you least. An address can geolocate to Singapore perfectly and still announce itself as a machine in a rack.

Where a Singapore mobile IP earns its cost

Local pricing and inventory. Grab, Shopee, Lazada and Carousell all serve different prices, different stock and different promos to Singapore. If you are collecting that, you need to be in it.

Ad verification. Checking what a campaign actually renders to a Singapore user, on a network a Singapore user is actually on, rather than what your Frankfurt scraper sees.

Account work where the platform reads the network. TikTok, Instagram and Xiaohongshu weigh carrier signals. An account that lives its whole life on one carrier address behaves differently from one that arrives from a hosting ASN.

App and payment testing. This is the one most teams skip and then get bitten by. PayNow and local 3DS flows route through Singapore acquirers with their own fraud rules, and a checkout that passes from a VPS can quietly fail for real customers.

Anything where 5.9 million people is the whole market. Singapore is small. There is no large residential pool here to hide in, which is exactly why the carrier signal carries weight.

The risks nobody puts on a pricing page

Shared reputation is the big one. Carriers here run carrier-grade NAT, so your address is shared with real subscribers. Usually that helps you, because the address has genuine human history on it. It also means somebody else’s behaviour lands on your address, and on a shared pool you have no idea who that somebody is.

Rotation breaking sessions. A mobile address changes when the modem reconnects. If that happens mid-login or mid-checkout, the site sees one cookie arriving from two addresses and drops the session. People blame the site. It was the proxy.

Resold pools sold as dedicated. Plenty of “Singapore mobile” offerings are slices of one modem sold to twenty customers, or worse, a residential pool with a Singapore label. Ask how many customers are on the SIM. A straight answer to that question tells you most of what you need to know about a provider.

Bandwidth pricing that punishes real work. Per-gigabyte pricing looks cheap until you run a browser automation job. Mobile data is not free to the operator, and anyone selling unlimited at a low flat rate is either overselling the line or throttling you later.

PDPA and the boring part. Singapore’s Personal Data Protection Act applies to personal data you collect here regardless of where your server sits. A proxy changes your route, not your obligations. Public data, the robots file respected, an official API used where one exists.

The setup I would run in 2026

One SIM per user, dedicated, not shared. This is the whole thing. If the address is yours alone, its history is yours alone, and the sole reason a mobile address is trusted is the history sitting on it.

Pick the carrier deliberately. Singtel has the widest peering footprint. M1 and StarHub score differently in some IP databases even for addresses a few streets apart. If you only ever test on one, you will miss the edge case that only shows up on the other two.

Hold the address for the length of the job. Rotate between jobs, never inside one. For login and checkout flows, pin it and leave it pinned.

Verify before you trust. Send one request through the proxy to an ASN lookup at the start of every session and read the type field. If it does not say cellular and the org is not one of the three carriers, stop, because everything you measure after that is measuring the wrong thing.

Control the rotation yourself. An address you can cycle on demand, from an API, is worth considerably more than one that cycles on a timer you cannot see.

Watch the device layer if you are testing apps. Android’s TelephonyManager reads the mobile country code off the SIM, not off your proxy config. A US handset on a Singapore proxy still reports MCC 310 to any SDK that asks, and attribution platforms do ask.

What I am less sure about

How long the carrier-signal advantage lasts. Detection has been moving toward device attestation and behavioural signals for a few years now, and the address is a smaller share of the decision than it was in 2023. It has not stopped mattering, and on payment and ad-serving paths it still clearly does. But anyone telling you an IP alone solves account trust in 2026 is selling something.

I also cannot tell you how the three carriers compare on long-run block rates across every platform. I see our own lines and our own targets. That is a real sample, not a complete one.

Getting one

We run dedicated Singapore mobile proxies on physical Singtel, M1 and StarHub SIMs, one SIM and one modem per customer rather than a shared pool, with rotation on demand over an API. Disclosure: that is our own infrastructure, which is also why the operating detail above exists at all.

The check that matters when you buy from anyone, us included: run the ASN lookup on day one, confirm the type comes back cellular and the org is the carrier you were sold, and ask how many other customers are on that SIM.
