These 10 Fixes Might Finally Solve Your Awful Cell Signal Issues

These phone hacks could finally fix your frustrating signal problems.

Summer road trips are all about freedom, keeping the windows down, playlists up, and adventure ahead. But nothing kills the vibe faster than hitting a dead zone with no signal. Suddenly your GPS freezes, your music cuts out, and you’re stuck with no way to reroute, stream, or even call for help if something goes wrong. Whether you’re crossing state lines or just heading off the beaten path for the weekend, staying connected is more important than ever.

Luckily, you don’t need a tech overhaul or a brand-new phone to fix bad reception. A few quick tricks can help boost your signal, no matter if you’re using an iPhone or Android. From adjusting your phone’s settings to switching up where you place it in your car, these hacks are easy to try, and they might just save your trip.

Whether you’re doing some routine phone maintenance or you’re stuck in an emergency, there are multiple ways to improve your reception on an iPhone or Android phone, no matter what type of phone plan you’re on. It might even come down to something as simple as toggling Airplane mode.

To go from dropped calls to full bars, here’s what you need to know.

Note: Although software across different iPhone models is relatively the same, Samsung Galaxy, Google Pixel and other Android phones may have different software versions, so certain settings and where they are located might differ depending on device.

To improve your cellphone service, try these steps first

The settings on your phone can help you get better cell service, but there are other tricks for improving your reception without even touching your phone’s software.

Move yourself so that there are no obstructions between your phone and any cell towers outside. That might involve stepping away from metal objects or concrete walls, which both kill reception. Instead, get to a window or go outside if possible.
Remove your phone case. It doesn’t hurt to remove whatever case you have on your phone, especially if it’s thick, so that the phone’s antenna isn’t blocked by anything and can get a better signal.
Make sure your phone is charged. Searching for and connecting to a stronger signal drains power, so if your phone battery is already low on charge, you may have a difficult time getting good service.

Always start by turning Airplane mode on and off

Turning your phone’s connection off and then back on is the quickest and easiest way to try and fix your signal woes. If you’re moving around from one location to another, toggling Airplane mode restarts the Wi-Fi, Bluetooth and cellular network modems, which forces them to find the best signal in the area.

Android: Swipe down from the top of your screen — to access the Quick Settings panel — and then tap the Airplane mode icon. Wait for your phone to completely disconnect from its Wi-Fi and cellular connections. It doesn’t happen instantly, so give it a good 15 seconds before you tap on the Airplane mode icon again.

iPhone: On the iPhone, you can access Airplane mode from the Control Center, but that varies depending on which iPhone model you have. On the iPhone X and later, swipe down from the top-right corner to access the Control Center. On older iPhone models, swipe up from the bottom of the screen. Then tap the Airplane mode icon, which will turn orange when it’s enabled. Again, wait up to 15 seconds before turning it off.

If Airplane mode doesn’t work, restart your phone

Our phones are miniature computers, and just like computers, sometimes you can fix issues like network connection by simply restarting them.

Android: Hold down the power button, or the power button and the volume down key (depending on your Android phone), until the on-screen menu shows up, and then tap Restart. If your phone doesn’t offer a restart option, you can simply tap Power Off to shut down your device, and then boot it back up with the power button.

iPhone: On the iPhone X and older models, hold down the sleep/wake button and either one of the volume buttons and then swipe right on the power slider to turn off the device. Wait until it fully turns off, then press down on the sleep/wake button to turn it back on.

Alternatively, you can do a force reset on your iPhone: Press the volume up button, followed by the volume down button and then press and hold the side button. Keep holding it in, after your phone’s screen goes black and until you see the Apple logo appear again.

If your iPhone has a home button, hold down the sleep/wake button until the power slider is displayed and then drag the slider to the right. Once the device is turned off, press and hold the sleep/wake button until you see the Apple logo.

Older phone? Take your SIM card out

Another troubleshooting step that might help is to remove your SIM card, if your phone has one, and then place it back in with the phone turned on. If the SIM card is dirty, clean it. If it has any physical defects, you may need to replace it.

You’ll need a SIM card tool — usually included in your phone’s box — or an unfolded paper clip or sewing needle to get the SIM tray out of your phone.

All phones: Remove the SIM card, check to see if it’s damaged and positioned in the SIM tray correctly, then put it back in your phone.

eSIM: For phones with an eSIM — that is, an embedded electronic SIM in your phone — there’s nothing for you to remove. The best you can do is restart your phone.

Check your carrier settings (and update your software)

Mobile carriers frequently send out carrier settings updates to help improve connectivity for calls, data and messages on their network. Although this feature is available on all iPhone models, it’s not universal on Android, so you might not find carrier settings if you don’t have a supported phone.

iPhone: Carrier updates should just appear, and you can update from the pop-up message that appears. To force your iPhone to check for a carrier settings update, go to Settings > General > About on your phone. If an update is available, you’ll be prompted to install it.

Android: As mentioned before, not all Android phones have carrier settings, so you’ll have to open the Settings app and type in «carrier settings» to find any possible updates. On supported Pixels, go to Settings > Network & internet > Internet, tap the gear next to your carrier name and then tap Carrier settings versions.

Reset your phone’s network settings

Sometimes all you need is a clean slate to fix an annoying connectivity issue. Refreshing your phone’s network settings is one way to do that. But be forewarned, resetting your network settings will also reset any saved Wi-Fi passwords, VPN connections and custom APN settings for those on carriers that require additional setup.

Android: In the Settings app, search for «reset» or more specifically «reset network settings» and tap on the setting. On the Pixel, the setting is called Reset Wi-Fi, mobile & Bluetooth. After you reset your network settings, remember to reconnect your phone to your home and work Wi-Fi networks.

iPhone: Go to Settings > Transfer or Reset iPhone > Reset > Reset Network settings. The next page will warn you that resetting your network settings will reset your settings for Wi-Fi, mobile data and Bluetooth. Tap Reset Network Settings and your phone will restart.

Contact your phone carrier

Sometimes unexpected signal issues can be traced back to problems with your wireless carrier. A cell tower could be down, or the tower’s fiber optic cable could have been cut, causing an outage.

For consistent problems connecting to or staying connected to a cellular or data network, it’s possible your carrier’s coverage doesn’t extend well into your neighborhood.

Other times, a newfound signal issue can be due to a defect with your phone or a SIM card that’s gone bad. Contacting your carrier to begin troubleshooting after you’ve tried these fixes is the next best step to resolving your spotty signal.

If all else fails, try a signal booster to improve cell reception

If after going through all of our troubleshooting steps, including talking to your carrier to go over your options, you’re still struggling to keep a good signal — try a booster. A signal booster receives the same cellular signal your carrier uses, then amplifies it just enough to provide coverage in a room or your entire house.

The big downside here is the cost. Wilson has three different boosters designed for home use, ranging in price from $349 for single room coverage to $999 to cover your entire home. To be clear, we haven’t specifically tested these models. Wilson offers a 30-day money-back guarantee and a two-year warranty should you have any trouble with its products.

Kohler Wants to Put a Tiny Camera in Your Toilet and Analyze the Contents

The company’s new Dekoda toilet accessory is like a little bathroom detective.

Some smart litter boxes can monitor our pets’ habits and health, so having a camera in our human toilet bowls seems inevitable. That’s just what kitchen and bathroom fixture company Kohler has done for its new health and wellness brand, Kohler Health.

The $599 Dekoda clamps over the rim like a toilet bowl cleaner, pointing an optical sensor at your excretions and secretions. It then analyzes the images to detect any blood and reviews your gut health and hydration status. Depending on the plan you choose, the subscription fee is between $70 and $156 per year.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

At toilet time, you sign in via a fingerprint sensor so that the device knows who’s using the facilities. (Please wash your hands before signing out or tracking your progress.) Then, check in with the app for the day’s analysis and trends over time.

Wait until you’re off the pot, though, before you start doomscrolling your health. The device has a removable, rechargeable battery and uses a USB connection.

Kohler says it secures your data via the aforementioned fingerprint scanner and end-to-end encryption, and notes that the camera uses «discreet optics,» looking only at the results, not your body parts.

«Dekoda’s sensors see down into your toilet and nowhere else,» the company says.

Kohler warns that the technology doesn’t work very well with dark toilet colors, which makes sense. I’m sure there could be an upsell model with a light on it. Maybe the company could add an olfactory sensor, since smell reveals a lot about your gut health too. It could track «session» length or buildup under the rim to alert whoever has responsibility to clean it.

Kohler must have been straining to find appropriate lifestyle photos to include with the publicity materials. Many of the images are hilarious, featuring fit-looking men and women drinking water and staring off into space contemplatively — probably thinking about gas.

Does Charging Your Phone Overnight Damage the Battery? We Asked the Experts

Modern smartphones are protected against overcharging, but heat and use habits can still degrade your battery over time.

Plugging your phone in before you head to bed might seem like second nature. That way by the time your alarms go off in the morning, your phone has a full charge and is ready to help you conquer your day. However, over time, your battery will start to degrade. So is keeping your phone plugged in overnight doing damage to the battery?

The short answer is no. Keeping your phone plugged in all the time won’t ruin your battery. Modern smartphones are built with smart charging systems that cut off or taper power once they’re full, preventing the kind of «overcharging damage» that was common in older devices. So if you’re leaving your iPhone or Android on the charger overnight, you can relax.

That said, «won’t ruin your battery» doesn’t mean it has no effect. Batteries naturally degrade with age and use, and how you charge plays a role in how fast that happens. Keeping a phone perpetually at 100% can add extra stress on the battery, especially when paired with heat, which is the real enemy of longevity.

Understanding when this matters (and when it doesn’t) can help you make small changes to extend your phone’s lifespan.

The science behind battery wear

Battery health isn’t just about how many times you charge your phone. It’s about how it manages voltage, temperature and maintenance. Lithium-ion batteries age fastest when they’re exposed to extreme levels: 0% and 100%.

Keeping them near full charge for long stretches puts additional voltage stress on the cathode and electrolyte. That’s why many devices use «trickle charging» or temporarily pause at 100%, topping up only when needed.

Still, the biggest threat isn’t overcharging — it’s heat. When your phone is plugged in and running demanding apps, it produces heat that accelerates chemical wear inside the battery. If you’re gaming, streaming or charging on a hot day, that extra warmth does far more harm than leaving the cable plugged in overnight.

Apple’s take

Apple’s battery guide describes lithium-ion batteries as «consumable components» that naturally lose capacity over time. To slow that decline, iPhones use Optimized Battery Charging, which learns your daily routine and pauses charging at about 80% until just before you typically unplug, reducing time spent at high voltage.

Apple also advises keeping devices between 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit) and removing certain cases while charging to improve heat dissipation. You can read more on Apple’s official battery support page.

What Samsung (and other Android makers) do

Samsung offers a similar feature called Battery Protect, found in One UI’s battery and device care settings. When enabled, it caps charging at 85%, which helps reduce stress during long charging sessions.

Other Android makers like Google, OnePlus and Xiaomi include comparable options — often called Adaptive Charging, Optimized Charging or Battery Care — that dynamically slow power delivery or limit charge based on your habits. These systems make it safe to leave your phone plugged in for extended periods without fear of overcharging.

When constant charging can hurt

Even with these safeguards, some conditions can accelerate battery wear. As mentioned before, the most common culprit is high temperature. Even for a short period of time, leaving your phone charging in direct sunlight, in a car or under a pillow can push temperatures into unsafe zones.

Heavy use while charging, like gaming or 4K video editing, can also cause temperature spikes that degrade the battery faster. And cheap, uncertified cables or adapters may deliver unstable current that stresses cells. If your battery is already several years old, it’s naturally more sensitive to this kind of strain.

How to charge smarter

You don’t need to overhaul your habits but a few tweaks can help your battery age gracefully.

Start by turning on your phone’s built-in optimization tools: Optimized Battery Charging on iPhones, Battery Protect on Samsung devices and Adaptive Charging on Google Pixels. These systems learn your routine and adjust charging speed so your phone isn’t sitting at 100% all night.

Keep your phone cool while charging. According to Apple, phone batteries perform best between 62 and 72 degrees Fahrenheit (16 to 22 degrees Celsius). If your phone feels hot, remove its case or move it to a better-ventilated or shaded spot. Avoid tossing it under a pillow or too close to other electronics, like your laptop, and skip wireless chargers that trap heat overnight.

Use quality chargers and cables from your phone’s manufacturer or trusted brands. Those cheap «fast-charge» kits you find online often deliver inconsistent current, which can cause long-term issues.

Finally, don’t obsess over topping off. It’s perfectly fine to plug in your phone during the day for short bursts. Lithium-ion batteries actually prefer frequent, shallow charges rather than deep, full cycles. You don’t need to keep it between 20% and 80% all the time, but just avoid extremes when possible.

The bottom line

Keeping your phone plugged in overnight or on your desk all day won’t destroy its battery. That’s a leftover myth from a different era of tech. Modern phones are smart enough to protect themselves, and features like Optimized Battery Charging or Battery Protect do most of the heavy lifting for you.

Still, no battery lasts forever. The best way to slow the inevitable is to manage heat, use quality chargers and let your phone’s software do its job. Think of it less as «babying» your battery and more as charging with intention. A few mindful habits today can keep your phone running strong for years.
