How to Choose a Mobile Proxy Provider (What the Cheap Ones Hide)

you searched “buy a mobile proxy” and got fifty providers. prices run from two dollars a gigabyte to forty. they all use the same three words: residential, rotating, unlimited. and almost none of them let you see the one thing that decides whether the proxy actually works, which is what is really behind the IP.

I run the hardware farm behind Singapore Mobile Proxy. real phones, real SIMs from SingTel, M1, and StarHub, racked in Singapore on the live carrier network. because I run the infrastructure, I know which corners get cut to hit a two dollar price point, and I know how to spot them from the outside before you pay. here is the whole checklist, and the cheap stuff it catches.

the short version

if you only do one thing from this list, do the first one. it takes thirty seconds and it eliminates most of the market.

the first lie: “mobile” that is not mobile

a real mobile proxy comes out of a carrier’s network, and its autonomous system number (its ASN) is registered as cellular. a lot of budget “mobile” proxies are plain datacenter IPs with a mobile label slapped on the dashboard.

the test takes thirty seconds. route a request through a trial IP to ipinfo.io/json and read the type field. if it says cellular, it is real. if it says hosting or isp, you are buying a datacenter proxy at a mobile price, and it will fail every fraud check that matters. a genuine Singapore mobile IP shows SingTel (AS9506), M1 (AS38322), or StarHub with type: mobile. anything else is relabeled.

if you want the why behind this, what is a mobile proxy explains why carrier IPs are structurally different from datacenter and residential ones at the network level. the short version: the ASN and the cellular classification are things a server rack cannot fake.

the contention ratio nobody advertises

the second thing cheap providers hide is how many other people are on your IP at the same time. this is the contention ratio, and it is the single biggest difference between a cheap proxy and a good one.

a two dollar plan puts hundreds of users behind the same handful of IPs. when one of them scrapes aggressively or gets an account banned, that reputation damage lands on you, because you share the address. a dedicated mobile proxy gives you a device nobody else is touching. ask the provider directly: is this IP shared or dedicated, and if shared, how many concurrent users. if they cannot or will not answer, assume it is crowded.

rotation you can actually control

cheap providers love the word “rotating” because rotation lets them recycle a small pool across many customers. but for real work you usually want the opposite: a sticky session that holds the same IP for several minutes while you finish a login, a checkout, or a multi-step form. forced rotation every thirty seconds looks like a bot and breaks anything stateful.

a serious provider gives you both: rotate on demand when you want a fresh IP, and a sticky session with a duration you set when you do not. if the only mode is “rotates whenever we feel like it,” that is a pool-recycling product, not a tool you control.

the location is often a stretch

a provider lists “Singapore,” but the IP is a Singapore-registered block routed out of a datacenter in another country, or a residential IP that geolocates to Singapore in one database and Malaysia in another.

if you actually need Singapore, for app store testing, for local pricing, or for a Singapore bank’s payment flow, you need the radio on a Singapore carrier, not just an IP that one database thinks is in Singapore. check the trial IP across two or three geolocation sources, not one. real carrier IPs agree across databases. stretched ones do not. if you are weighing carrier IPs against home-broadband IPs for this, residential vs mobile proxies lays out which one survives which checks.

where the cheap price hides the real cost

two dollars a gigabyte sounds great until you read how they count gigabytes. some meter every byte including failed requests and retries. some have a low monthly cap and an overage rate three times the headline price. “unlimited” plans almost always have a fair-use throttle that kicks in quietly once you pass a threshold they do not publish.

before you sign up, ask two questions: what exactly counts against my bandwidth, and what happens when I hit the cap. a provider that charges per device or per port instead of per gigabyte is often cheaper for real workloads, because heavy use does not punish you.

carrier diversity, or the lack of it

a lot of “mobile proxy networks” are actually one carrier, or even one cell tower, with a pile of SIMs. that is fragile. if that carrier has an outage or that ASN gets flagged, your whole proxy supply dies at once. it also means you cannot test how your target behaves across different networks.

a real farm spreads across multiple carriers, in our case SingTel, M1, and StarHub, so you can switch networks, compare behavior, and survive a single-carrier problem. ask which carriers they actually run. if the answer is vague, it is probably one. for the newer end of this, 5G mobile proxies in Singapore covers what the carrier and radio generation actually change.

what happens when the connection drops

mobile proxies reconnect. the SIM re-registers with the tower, and the IP can change. a cheap provider hands you a connection string and wishes you luck. a good one gives you a stable endpoint that survives the reconnect, so your code keeps talking to the same gateway even when the underlying IP rotates. ask how reconnects are handled and whether the endpoint stays constant. if a dropped tower connection means fetching a new proxy string every time, that is work you will be doing at three in the morning.

support you can test before you buy

support and replacement barely exists at the bottom of the market. when an IP gets blocked by your target, and on a shared cheap pool it will, what is the path to a clean one? a real provider replaces a burned IP or rotates you to a fresh device quickly, through a human or an API. a two dollar reseller points you at a ticket queue that answers in four days, by which time your project is stalled.

before you buy, send one pre-sales question and see how fast and how specifically they answer. the reply you get before they have your money is the best reply you will ever get from them.

prove it before you pay

this is the one that protects you from all the others. a confident provider will let you test a real IP. in those few minutes you can run every check above: ASN type, geolocation across databases, a sticky session, and a real request to your actual target. a provider that will not let you verify the IP before you pay is telling you something.

here is the ten-minute test I would run on anyone, including us:

1. hit ipinfo.io/json and confirm type is cellular and the org is a real carrier.
2. check the same IP on a second and third geo database and confirm they agree on the country.
3. open a sticky session and confirm the IP holds for at least a few minutes without forced rotation.
4. run your actual workload, your scrape, your login, your checkout, not a generic speed test. the only result that matters is whether your real task succeeds.
5. ask one hard support question and time the reply.

if a provider passes all five, the price is fair almost regardless of what it is. if it fails the first one, nothing else matters.

the number that actually matters

the objection is always about price. why pay more when someone else lists two dollars a gigabyte? because the cheapest proxy per gigabyte is almost never the cheapest proxy per successful request.

a customer came to me last month after three weeks on a two dollar plan. fifteen retail accounts kept getting locked, even though the dashboard showed a Singapore IP every time. we ran the ASN check together in about a minute. the type field said hosting. he had been on relabeled datacenter IPs the whole time, on a shared pool with who knows how many other people. the accounts were not the problem. the IP class was. he moved to dedicated cellular IPs on real SingTel and M1 SIMs, held sticky sessions through each login instead of rotating mid-flow, and the lockouts stopped. same accounts, same scripts, different proxy. the cheap plan cost him three weeks and fifteen warm accounts, which is far more expensive than the price difference ever was.

the real number is not dollars per gigabyte. it is dollars per task that completes. a dedicated mobile IP on a real carrier that succeeds the first time is usually cheaper on that number, even when the sticker price is higher.

the honest caveat

the right choice depends on what you are doing. if you just need to check that a webpage shows Singapore content once, the cheapest shared rotating proxy is fine, and you do not need any of this. the checklist matters when reliability matters: accounts that get banned, payments that get fraud-scored, or scrapes that need to finish. for low stakes, buy cheap. for anything that breaks when the IP is not genuinely what it claims to be, run the ten-minute test first.

mobile proxy marketing is built to make every provider look identical, because if you cannot tell them apart, you buy on price alone. the thirty-second ASN check, the contention question, and a real trial on your own workload are what cut through it. the provider who is confident in the product is the one who tells you to go check.

if you want to run that ten-minute test against real SingTel, M1, and StarHub carrier IPs, Singapore Mobile Proxy runs the hardware. start a trial at the Singapore Mobile Proxy home page.
