Singapore runs on four mobile networks — Singtel, StarHub, M1, and SIMBA — all under the +65 country code, with 8-digit mobile numbers that start with 8 or 9 and no regional area codes. Finding the right phone number tracker Singapore means knowing what level of location detail you actually need and which tools work across all four carriers. This guide covers 7 options, with honest pricing, real pros and cons, and a plain-language breakdown of Singapore’s consent laws.

How Phone Number Tracking Works in Singapore

Singapore mobile numbers are 8 digits, begin with 8 or 9, and require no area code — just dial +65 followed by the full number. There are no prefix-to-carrier indicators that reliably identify which network a number is on, because Singapore has had Mobile Number Portability since 2008, meaning subscribers can switch carriers while keeping the same number.

Two tracking methods exist for Singapore numbers:

• SMS link-based GPS tracking — the service sends a text to the +65 number containing a tracking link. When the recipient taps the link, their GPS coordinates are captured and displayed on a map in real time. This delivers street-level accuracy but requires the target to click.
• Carrier and database lookup — the tool cross-references the number against carrier or public records to return the registered operator and approximate region. No action from the target is needed, but results show registration data only, not a live location.

For GPS-level accuracy on a Singapore number, only the first method works. Tools like Scannero and Detectico use it. Free tools like eMobile Tracker use the second.

Best Phone Number Trackers for Singapore

1. Scannero — Real-Time GPS for Any +65 Number

You need to locate a Singapore mobile number right now — not find out which carrier it was originally registered to, but see exactly where the phone is on a map. The challenge most people hit: tools that promise GPS tracking either require installing software on the target phone, which is impossible for an unknown caller, or return only a broad database region that may be months out of date.

Scannero solves this without touching the target device. Enter the +65 number, and Scannero sends a discreet SMS containing a tracking link to that number. The moment the recipient taps the link, their device’s GPS fires and their exact coordinates appear on your Scannero dashboard map in real time. The whole process — from entering the number to seeing the pin on the map — takes under 3 minutes. No app download on your end, and nothing installed on theirs.

Key features:

• Real-time GPS tracking compatible with all four Singapore carriers — Singtel, StarHub, M1, and SIMBA — and any MVNO operating on those networks
• Fully web-based dashboard — works from any browser on any device with no download required
• Reverse phone lookup to identify the name and carrier linked to a +65 number
• Data leak checker — scans breach databases to flag if your phone number or email has been exposed
• Lost phone SMS — sends a customized message to any +65 number to prompt a finder to return the device
• Anonymous voice message tool — converts a written note to a voice message and delivers it without revealing your number

Pricing: $0.89 for a 24-hour trial with access to core GPS tracking features. The monthly unlimited plan is $49.80, covering unlimited tracking requests across any +65 or international numbers. Review subscription renewal terms carefully before purchasing.

Pros:

• Works on any Singapore number regardless of carrier or MVNO — no carrier compatibility restrictions
• No app installation required on the target device — the only method that produces GPS-level results for unknown numbers
• Street-level GPS accuracy once the link is clicked, versus the city-level or carrier-region data returned by database tools
• $0.89 trial makes it practical for one-off use cases without a subscription commitment

Cons:

• Location is only transmitted after the recipient clicks the SMS link — a number that doesn’t receive or open messages returns no data
• Pricing structure: the $49.80/month subscription cost is not prominently surfaced at the start of signup; read the full terms before entering payment details

Who it’s best for: Anyone needing to locate a specific Singapore number — a family member, an unknown caller, a lost or stolen device — without installing software. Practical for both one-off use (trial) and ongoing family safety monitoring (monthly plan).

Unlike app-based trackers like mSpy or FamiSafe, which require you to physically access and configure the target phone before tracking begins, Scannero requires nothing beyond the phone number. In Singapore, where all four networks support standard SMS delivery, the tracking link reaches the recipient through the same channel they use daily.

Start tracking a Singapore number at Scannero — results in under 3 minutes.

2. Detectico — SMS-Based Tracker with +65 Support

Detectico uses the same SMS tracking link mechanism as Scannero and explicitly supports Singapore’s four major carriers: Singtel, StarHub, M1, and SIMBA. Enter the +65 number, select a preset message, and receive GPS coordinates once the recipient taps the link. The interface is minimal and optimised for speed, making it a practical alternative for users who want a straightforward SMS-based tracker.

Key features:

• SMS GPS tracking link confirmed compatible with Singtel, StarHub, M1, and SIMBA numbers
• Real-time GPS location displayed on a map dashboard
• Works on iOS, Android, and older feature phones capable of receiving SMS
• Reverse lookup included on higher-tier plans

Pricing: $0.89 short-term trial. Monthly subscriptions start at approximately $29.99/month. Higher tiers include unlimited tracking requests.

Pros:

• Explicit Singapore carrier support documented by the platform
• Simpler interface than Scannero — fewer features, lower cognitive load for basic use
• International number support means it works for Singapore numbers dialled from abroad

Cons:

• Same link-click dependency as all SMS-based trackers — no click means no location data
• Subscription pricing jumps significantly after the trial period; confirm renewal terms before subscribing

Best for: Users who need a direct SMS-based phone number tracker Singapore with confirmed carrier compatibility and a clean, minimal interface.

3. HeyLocate — Free Consent-Based Tracker

HeyLocate offers GPS location tracking for Singapore numbers at no cost. It sends an SMS consent request to the target +65 number. Once the recipient grants permission, their location is displayed on an interactive map with accuracy up to 1 metre. No registration is required to use it, and the platform returns operator details and number type alongside the location result.

Key features:

• Free GPS tracking via SMS consent link
• Location accuracy up to 1 metre on an interactive map
• Returns operator details, number type, and planning area for Singapore numbers
• No registration or account required to start

Pricing: Completely free to use.

Pros:

• Zero cost — the only genuinely free option in this list that returns GPS-level accuracy
• No registration means instant access with no data submitted upfront
• Consent-based model is PDPA-aligned — location is only shared after explicit recipient approval

Cons:

• Limited to Singapore and select partner-supported regions — not a global tracker
• Location tracking only works if the recipient actively grants permission; cannot be used for non-cooperative targets

Best for: Users in Singapore who need a one-off GPS location result and want a free tool without any subscription or account creation.

4. Truecaller — Caller ID for Singapore Numbers

Truecaller’s coverage of Singapore numbers is strong, given the size of Singtel and StarHub’s subscriber databases. Rather than sending a tracking link, it cross-references incoming numbers against a crowdsourced global database to show the caller’s name, registered region, and spam rating before you answer. It does not provide GPS coordinates.

Key features:

• Caller ID with name, carrier, and registered region for most +65 numbers in its database
• Spam call detection and blocking — useful in Singapore where phone scams targeting local numbers are common
• SMS filtering to remove unwanted texts
• Call recording available on Android in supported regions
• Business caller verification badge

Pricing: Free tier covers core caller ID. Truecaller Gold at approximately $2.99/month adds extended caller history, advanced ID, and ad removal.

Pros:

• Passive operation — no tracking link or target action required
• Broad Singapore number coverage for the three legacy carriers (Singtel, StarHub, M1)
• Free tier handles most daily identification needs with no payment

Cons:

• Location data is carrier-region or city level only — no GPS position
• Numbers ported via MNP may show incorrect carrier details as database updates lag behind network changes

Best for: Anyone who regularly receives unknown calls from Singapore numbers and wants to see the caller’s name and general location before answering, without sending any tracking requests.

5. mSpy — Full Device Monitor with GPS

mSpy is a full-spectrum phone monitoring platform that includes GPS location tracking alongside call logs, messaging app monitoring, and browser history. It requires installation on the target device, which means it is designed for monitoring a phone you have authorised access to — typically a parent tracking a child’s device, or an employer monitoring a company-issued handset in Singapore.

Key features:

• Real-time GPS tracking with detailed location history and timestamps
• Call log monitoring — records all incoming and outgoing calls
• WhatsApp and Telegram message monitoring — both apps dominant in Singapore
• Geofencing with custom zone alerts
• Keylogger and browser history access

Pricing: Plans start at approximately $29.99/month for the basic tier. Premium plans with full feature access are available at higher prices. No free plan; a demo is available on the website.

Pros:

• Most comprehensive feature set in this list — location, calls, messages, and app activity in one dashboard
• Supports WhatsApp and Telegram monitoring, the two most-used messaging apps in Singapore
• Stealth install mode means the app does not appear in the target device’s app drawer

Cons:

• Physical access to the target device is required for initial setup — cannot be used for unknown caller tracking
• At $29.99/month and above, it is the most expensive option in this comparison

Best for: Parents in Singapore who need full oversight of a child’s device, including location history, messaging activity, and call logs, on a phone they can physically access for setup.

6. FamiSafe — Family GPS Tracker for Singapore

FamiSafe by Wondershare combines real-time GPS location tracking with parental control features including screen time management, app limits, and web filtering. Like mSpy, it requires the FamiSafe app to be installed on the target device. Its strength is ongoing location monitoring with geofencing — making it better for family safety than for tracing unknown callers.

Key features:

• Real-time GPS tracking with continuous location history
• Geofencing alerts when the device enters or exits a set zone — practical for monitoring children’s movements between home, school, and tuition centres
• Screen time controls and app usage limits
• Content filtering for web browsing
• Compatible with iOS, Android, and Windows

Pricing: Starts at approximately $10.99/month for a single device. Multi-device family plans available at higher tiers.

Pros:

• GPS plus geofencing plus screen time in one platform — complete parental control, not just a location ping
• Cross-platform support covers all common device types used in Singapore
• More affordable than mSpy for families focused on location monitoring rather than full device surveillance

Cons:

• App installation on the target device is required — physical access to the child’s phone is needed for setup
• No functionality for tracing unknown numbers or callers outside your existing family circle

Best for: Parents who want continuous GPS tracking with geofencing alerts and usage controls for their child’s Singapore phone, without needing full communication monitoring.

7. eMobile Tracker — Free Carrier Lookup for +65

eMobile Tracker is a free web tool that identifies the carrier associated with any phone number, including Singapore +65 numbers. Enter the number and it returns the operator name (Singtel, StarHub, M1, or SIMBA) and country. It does not provide GPS tracking or real-time location data of any kind.

Key features:

• Instant carrier identification for +65 Singapore mobile numbers
• Works directly in any browser — no account, no login required
• Returns operator name and number type (mobile/landline)
• Supports international numbers beyond Singapore

Pricing: Completely free.

Pros:

• Zero cost and zero setup — immediate results with no account required
• Useful for identifying which Singapore carrier an unknown number belongs to before deciding whether to call back
• No personal data submitted to use the service

Cons:

• Returns carrier data only — no GPS coordinates and no real-time location
• Due to Singapore’s Mobile Number Portability, the carrier shown may no longer be accurate if the number has been ported since registration
• Provides no information about the phone’s physical location

Best for: Users who need to quickly identify the carrier behind an unknown +65 number — for example, to check call cost before dialling back, or to confirm a number is a local mobile rather than a landline.

Is It Legal to Track a Phone Number in Singapore?

Singapore’s Personal Data Protection Act (PDPA), enacted in 2012 and amended in 2021, classifies phone numbers as personal data. Collecting, using, or disclosing a Singapore phone number without consent is a breach of the PDPA. Penalties can reach S$1 million, or 10% of annual turnover for larger organisations.

Consent-based tracking is explicitly legal under the PDPA. Tools like Scannero and HeyLocate comply with this requirement through the SMS link model — location is only captured after the recipient voluntarily taps the link, making consent both explicit and documented. Legal use cases also include:

• Parental monitoring of minor children’s devices, where parental authority provides the consent basis
• Employer tracking of company-issued devices, with prior written consent from employees

Tracking someone in Singapore without their knowledge or consent — regardless of the tool used — may constitute a breach of the PDPA and potentially criminal law. For specific legal questions, refer to the Personal Data Protection Commission at pdpc.gov.sg.

Singapore Number Prefix Guide: Identifying the Carrier

Singapore mobile numbers are 8 digits and begin with 8 or 9. Unlike some countries where the number prefix reliably identifies the carrier, Singapore introduced full Mobile Number Portability (MNP) in 2008 — meaning subscribers can switch between Singtel, StarHub, M1, and SIMBA at any time while keeping their existing number.

Because MNP has been active for over 15 years, you cannot determine which carrier currently holds a Singapore number based on its digits alone. A number beginning with 83 may be on Singtel today and SIMBA tomorrow. Tools like eMobile Tracker that display a carrier label for +65 numbers may show the original carrier at registration, which is not necessarily the current network.

Which Phone Number Tracker Is Right for You?

Choosing the right Singapore phone number tracker comes down to what you need the result to look like:

• Need GPS-level accuracy for any +65 number without touching the target device? Use Scannero — $0.89 trial, works across all four Singapore carriers, location result in under 3 minutes.
• Need a free GPS tracker with consent-based compliance? Use HeyLocate — no account required, no cost, PDPA-aligned.
• Need to identify an unknown Singapore caller before you answer? Use Truecaller — free, passive, and broadly covers Singtel and StarHub numbers.
• Need full device monitoring including messages and calls for a family member’s phone? Use FamiSafe for location plus parental controls, or mSpy for complete device oversight.

For most users who need to locate a specific +65 number without app installation, Scannero delivers the most practical combination of speed, accuracy, and low entry cost. Start with the $0.89 trial and verify the result before committing to a plan.
