Fix Bad Service on iPhone X: Step-by-Step

If your iPhone X shows poor cellular reception, dropped calls, or slow data, the fix usually starts with software settings and SIM card checks, not a trip to the repair shop. This guide walks you through the most common causes and solutions, from toggling Airplane Mode to resetting network settings, and tells you when the issue is hardware-related.

Why Your iPhone X Might Have Bad Service

The iPhone X, released in 2017, uses the Qualcomm or Intel modem depending on the model. Bad service can stem from several sources:

• Software glitches – iOS bugs can cause the phone to lose signal or connect to the wrong network band.
• SIM card issues – A damaged or improperly seated SIM card can interrupt service.
• Carrier settings – Outdated carrier settings can affect network compatibility.
• Antenna or hardware damage – Drops or water exposure can damage the internal antennas.
• Network congestion or coverage – Sometimes the problem is the network itself, not your phone.

Quick Software Fixes to Try First

Start with these simple steps, as they resolve most temporary signal issues:

1. Toggle Airplane Mode – Swipe down from the top-right corner (or open Control Center) and tap the airplane icon. Wait 10 seconds, then turn it off. This forces the phone to re-register with the network.
2. Restart your iPhone X – Press and hold the side button and either volume button until the slider appears. Slide to power off, wait 30 seconds, then turn it back on.
3. Check for carrier settings update – Go to Settings > General > About. If an update is available, a prompt will appear. Follow the on-screen instructions.
4. Update iOS – Go to Settings > General > Software Update and install any available updates. Apple regularly fixes cellular bugs in iOS updates.

Reset Network Settings

If the quick fixes don’t work, resetting network settings can clear corrupted Wi-Fi, Bluetooth, and cellular configurations. This does not delete your personal data, but it will erase saved Wi-Fi passwords and Bluetooth pairings.

1. Go to Settings > General > Transfer or Reset iPhone > Reset.
2. Tap Reset Network Settings.
3. Enter your passcode and confirm.

After the phone restarts, you’ll need to reconnect to Wi-Fi networks and re-pair Bluetooth devices. Your cellular service should re-establish automatically.

Check Your SIM Card

A faulty or dislodged SIM card is a common cause of intermittent service. Here’s how to check:

1. Use the SIM eject tool (or a paperclip) to pop out the SIM tray on the right side of the phone.
2. Inspect the SIM card for any visible damage or dirt. Clean it gently with a soft, dry cloth.
3. Reinsert the SIM card firmly, ensuring it sits flat in the tray.
4. If the problem persists, try the SIM card in another phone (if possible) to see if the issue follows the card or the phone.

If your SIM is damaged, contact your carrier for a replacement. If the SIM works in another phone, the problem is likely in your iPhone’s hardware.

When It’s a Hardware Problem

If software resets and SIM checks don’t help, the issue may be physical. Common hardware causes include:

• Damaged antenna flex cables – These connect the antennas to the logic board and can loosen or break after a drop.
• Water damage – Even though the iPhone X is IP67 water-resistant, water can still corrode internal components over time.
• Faulty modem – The cellular modem chip can fail, especially after impact or overheating.

If you suspect hardware damage, your best option is to contact Apple Support or visit an Apple Authorized Service Provider. They can run diagnostics and offer repair options. Avoid opening the phone yourself unless you have experience, as it can void any remaining warranty and cause further damage.

Carrier-Specific Troubleshooting

Sometimes the issue is with your carrier, not your phone. Try these steps:

• Check for outages – Visit your carrier’s website or social media for service alerts in your area.
• Update carrier settings – As mentioned, go to Settings > General &em> About and see if a carrier update is available.
• Toggle LTE/5G (if applicable) – Go to Settings > Cellular > Cellular Data Options and switch between LTE and 4G to see if one works better.
• Contact your carrier – They can check your account for any blocks, verify your plan includes data, and refresh your network connection from their side.

Frequently Asked Questions

Why does my iPhone X show “No Service� even after resetting network settings?

If “No Serviceâ€� persists, it’s likely a hardware issue, especially if the SIM works in another phone. It could also be a carrier problem, so contact your carrier first to rule out account or coverage issues. If they confirm the network is fine, the modem or antennas may need repair.

Will restoring my iPhone X to factory settings fix bad service?

A factory reset can fix software corruption that might affect cellular connectivity. However, it’s a drastic step – back up your data first. If the problem is hardware, a factory reset won’t help. Try network settings reset first, as it’s less invasive.

Can a bad case cause poor signal on iPhone X?

Yes, some cases made with thick metal or certain materials can block cellular antennas. Try removing the case and testing the signal. If it improves, consider a case with better signal transparency.

Does the iPhone X support 5G?

No, the iPhone X only supports 4G LTE. If you’re in an area with 5G coverage, the phone will fall back to LTE, which is normal. If LTE is slow, it could be network congestion or a coverage gap.

How much does it cost to fix iPhone X hardware issues?

Costs vary by region and provider. Apple offers out-of-warranty repair pricing, but it’s best to get a quote from Apple Support or an authorized service provider. Third-party repair shops may be cheaper, but ensure they use quality parts.

Is there a way to improve signal strength without repairs?

Yes, try these tips: keep the phone updated, reset network settings, use Wi-Fi calling when available, and avoid areas with known weak coverage. Signal boosters (repeaters) can help in buildings, but they require carrier approval in some regions.
