Every new generation of mobile networks arrives with predictions about what it will change, and warnings about what it will cost. 5G is no different. Supporters point to speed, low latency and the ability to connect millions of devices. Critics point to more sensors, more data and more places where personal information can leak. The truth is more nuanced than either camp suggests. 5G is mostly a faster pipe, and the privacy issues that matter most are about who collects data and what they do with it. This guide separates the technology from the business models, explains what is different about 5G, covers location data in particular and gives practical steps to limit tracking. For the phone-level view, start with our article on how smartphones constantly send personal information.
1. What 5G changes
5G is the fifth generation of mobile network technology. Compared with earlier generations it offers higher speeds, lower delay and the capacity to connect far more devices per area. It also relies on denser deployments of small cells, which can improve how precisely networks estimate a device’s position. Security improvements are part of the design, including stronger protection for subscriber identifiers.
Those changes enable new uses: connected vehicles, industrial sensors, smart cities, remote medicine and a growing universe of consumer devices. Each connected device is another source of data. See our article on the Internet of Things as a personal information pipeline.
2. What 5G does not change
It is easy to blame a network standard for problems that predate it.
- Apps still decide what they collect. Permissions determine whether a weather app can read your location all day.
- Advertisers still build profiles. Advertising identifiers and trackers work on any network.
- Brokers still compile records. People-search sites publish phone numbers and addresses regardless of how your phone connects.
- Scammers still call and text. Spoofing and phishing do not depend on 5G.
- Account security remains your job. Weak passwords and SIM-swap vulnerabilities exist on every network.
Understanding this prevents wasted worry. Turning off 5G will not stop apps from tracking you. Adjusting permissions, accounts and public listings will.

3. The location data problem
Your phone’s location is among the most sensitive data about you. It reveals where you live, work, worship, receive treatment and spend time with others. Several parties may have access.
Carriers
Mobile carriers know which towers your phone uses and can estimate your position. In 2024 the Federal Communications Commission announced penalties against major carriers over the sharing of customer location data without adequate safeguards, as described at fcc.gov. The lesson is that carrier-held location data has been shared with third parties in ways customers did not expect. Check your carrier’s privacy settings and opt out of non-essential data sharing.
Apps and software development kits
Apps may collect precise location and share it with analytics and advertising partners. Brokers can aggregate location trails. Even when data is described as anonymous, repeated visits to a home and workplace can point to an individual.
Wi-Fi, Bluetooth and sensors
Location can also be inferred from nearby networks and devices, even when GPS is off.
Public listings
Separate from live location, people-search sites publish where you live and what number you use, which makes it easier for someone to link a phone number to a street.
4. Other privacy and security issues
SIM swapping
Criminals trick carriers into moving your number to a new SIM, then use it to reset passwords and intercept verification codes. Protect your account with a PIN or passcode and avoid text messages for authentication when apps are available. The FTC explains what to do if your phone number is hijacked.
Fake base stations
Devices that mimic cell towers can capture identifiers and sometimes force connections to weaker modes. This is a niche threat for most people, but worth knowing if you are a journalist, activist or target of surveillance.
Connected devices
Cheap sensors, cameras and wearables on cellular connections may have weak security. Check update policies before buying.
Spam and robocalls
Calls and texts continue to rise, whatever network carries them. See what to do about telemarketing calls and how to report spam texts.
5. How to limit tracking
Audit app permissions
Open your phone’s privacy settings and review location access. Choose “never” or “while using” for most apps, and switch off precise location where approximate is enough. Our guide to privacy settings on your devices and iPhone settings to turn off can help.
Limit ad tracking
Reset or restrict your advertising identifier and disable personalized ads.
Opt out with your carrier
Look in your carrier account for marketing, analytics and location-sharing settings and turn off non-essential options.
Secure your number
Ask your carrier to add a PIN or port-out lock. Use an authenticator app or passkey for sensitive accounts.
Use encrypted messaging
For private conversations, use apps that offer end-to-end encryption.
Check what apps share
See how to find out if your newest phone app is sharing your private data.
Reduce public exposure of your number
Remove your phone number from people-search sites. Official pages exist for Spokeo, PeopleConnect and That’s Them. Our guide to removing your cell phone number from the internet provides a routine.
Keep software updated
Install security updates for your phone, apps and connected devices.
6. Realistic expectations
You cannot be invisible on a mobile network, because connecting requires identifiers. What you can do is limit unnecessary collection, reduce the number of third parties that receive your location and make it harder for strangers to link your phone number with your identity and address. The FBI’s Internet Crime Complaint Center received 67,456 personal data breach complaints in 2025, with about $1.31 billion in reported losses (ic3.gov). Keeping less data in circulation reduces what a breach can reveal.
7. Health claims and rumors
Public discussion of 5G sometimes drifts into unfounded claims. This article focuses on privacy and security, which can be evaluated with evidence. For questions about health effects, rely on assessments from health and communications agencies rather than social media posts.
8. Timeline: tightening your mobile privacy
| When | Action |
|---|---|
| Day 1 | Add a carrier PIN, review location permissions |
| Week 1 | Opt out of carrier data sharing, limit ad tracking |
| Week 2 | Remove your phone number from people-search sites |
| Month 1 | Audit installed apps, delete unused ones |
| Quarterly | Recheck permissions and listings |
9. Questions to ask your carrier
Your mobile carrier is one of the few companies that knows roughly where you are all day. You can ask it what location and usage data it collects, how long it keeps it, whether it shares it with partners and how to opt out. Many carriers offer account-level controls for marketing and analytics. Take ten minutes to find them. If answers are vague, that is a sign to be more careful with what the carrier collects and to use app-level controls more strictly.
10. Public Wi-Fi, hotspots and home networks
5G does not remove the need for sound habits on other networks. Public Wi-Fi may be monitored or spoofed, so avoid logging in to sensitive accounts on open networks and use your cellular connection for banking. At home, change the default router password, keep firmware current and give guests a separate network. Fast mobile networks make hotspots and home internet alternatives popular, and a poorly secured hotspot is an open door.
11. Three scenarios and what to do
Scenario 1: Your phone suddenly loses service. Contact your carrier from another device and secure email and financial accounts.
Scenario 2: A weather app wants “always” location access. Choose approximate or while-using only.
Scenario 3: A stranger texts using your full name. Do not reply; check for people-search listings and block the number.
12. Myths and facts
| Myth | Fact |
|---|---|
| 5G reads my messages | It transports data; content privacy depends on apps and encryption |
| Turning off 5G stops tracking | Apps and carriers still collect |
| Carriers never share location | They have been penalized for improper sharing |
| Airplane mode makes me untraceable | It stops transmissions, but data stored earlier remains |
| Only criminals care about location privacy | It affects everyone’s safety |
13. Common mistakes
- Granting “always” location to casual apps.
- Skipping a carrier PIN.
- Using text messages for security codes when apps are available.
- Ignoring carrier privacy settings.
- Leaving your phone number public.
- Delaying updates.
14. Questions to ask yourself
Which apps know where I am right now? Does my carrier share data about me? Could a stranger link my number to my address? Do I have a PIN on my mobile account? Start with the weakest answer.

17. Frequently Asked Questions
Does 5G make my phone easier to track?
Denser cell networks can support more precise location estimates, but the larger privacy exposure comes from apps, carriers and data sales rather than the radio standard itself.
Can carriers sell my location?
Carriers have been criticized and penalized for sharing customer location data without adequate consent. Review your carrier’s privacy settings and opt out of data sharing where offered.
Is 5G less secure than older networks?
5G includes improved security features, such as stronger encryption of subscriber identifiers, but security also depends on implementation, devices and the apps you use.
What is a SIM swap?
It is an attack in which a criminal convinces a carrier to move your number to their device, letting them intercept calls and verification codes. A carrier PIN reduces the risk.
Should I turn off location services?
Turn them off or limit them to while-using for apps that do not need constant access. Some features such as maps and emergency services benefit from location.
How can I limit what apps learn about me?
Review permissions, disable ad tracking, delete unused apps and use privacy settings for your device.
