How to Activate 5G on Android and iPhone

This guide walks you through turning on 5G on both Android and iPhone devices. You’ll learn where the settings are, what each 5G mode means, and how to fix common issues when 5G isn’t connecting. Before you start, make sure your phone model supports 5G and that you’re on a plan that includes 5G access from your carrier.

What You’ll Need

• A 5G-capable phone (check your model on the manufacturer’s website if unsure).
• A carrier plan that includes 5G (most major carriers include it by default, but some prepaid plans may not).
• 5G coverage in your area — you can check your carrier’s coverage map.
• An active SIM card (physical or eSIM) that supports 5G. If you’re using an older SIM, contact your carrier for a free replacement.

Step-by-Step

Enable 5G on iPhone

1. Open the Settings app.
2. Tap Cellular (or Mobile Data in some regions).
3. Tap Cellular Data Options (or Mobile Data Options).
4. Tap Voice & Data.
5. Choose one of the 5G options:
   • 5G Auto — This is the default and recommended. It uses 5G only when it won’t significantly reduce battery life.
   • 5G On — Always uses 5G when available, even if it drains battery faster.
   • LTE — Turns off 5G entirely. Use this if you want to save battery or if 5G is unstable.
6. If you have a dual-SIM iPhone, repeat these steps for the other line by going to Settings > Cellular, selecting the line, then tapping Cellular Data Options.

Enable 5G on Android (Samsung, Google Pixel, OnePlus, etc.)

Android phones vary by manufacturer, but the general path is similar. Here’s how to do it on most devices:

1. Open the Settings app.
2. Tap Connections (on Samsung) or Network & internet (on Pixel and most others).
3. Tap Mobile networks (sometimes called Cellular networks).
4. Tap Network mode (or Preferred network type).
5. Select 5G/LTE/3G/2G (or NR/LTE — NR stands for New Radio, the technical name for 5G).
6. If you don’t see a 5G option, your phone may have it under Settings > Connections > Mobile networks > Network mode on Samsung, or Settings > Network & internet > Internet > (your SIM) > Preferred network type on Pixel.

Additional Steps for Some Carriers

Certain carriers (like Verizon, AT&T, T-Mobile) may require you to enable 5G standalone for better coverage. This is usually found in the same network settings menu and may be labeled 5G Standalone or 5G SA. If you don’t see it, your carrier may not support it yet.

Common Mistakes

• Assuming your phone is 5G-capable — Many budget phones and older models don’t support 5G. Check the specs on the manufacturer’s website or in the phone’s settings under About phone.
• Not having a 5G SIM — Some carriers require a newer SIM card to access 5G. If you’ve had the same SIM for years, contact your carrier.
• Choosing “LTE” accidentally — On iPhone, if you select LTE in Voice & Data, you’re turning 5G off. Make sure you pick 5G Auto or 5G On.
• Forgetting to toggle 5G for each SIM — On dual-SIM phones, each line has its own network mode. You must enable 5G on the line you’re using for data.
• Ignoring carrier settings updates — Sometimes carriers push a settings update that enables 5G. If you don’t see the 5G option, go to Settings > General > About on iPhone and wait a few seconds for a carrier update prompt. On Android, check for system updates in Settings > About phone.

Tips

• Use 5G Auto on iPhone — It balances speed and battery life. 5G On can drain battery noticeably, especially in areas with weak signal.
• Keep your phone updated — Both Android and iPhone receive updates that improve 5G performance. Check for updates regularly.
• Restart your phone after changing settings — This helps the phone reconnect to the network with the new settings.
• Check coverage before troubleshooting — If you’re in a basement or rural area, 5G may simply not be available. Use your carrier’s coverage map or look at the status bar icon — if it shows “5G” but speeds are slow, you might be on a weaker band.
• Use Wi-Fi calling when 5G is weak — If calls drop, enable Wi-Fi calling to maintain call quality over Wi-Fi.

Troubleshooting

5G option is missing

• Check if your phone model is 5G-capable. If it is, the option may be hidden because your carrier doesn’t support 5G on that device yet.
• Update your carrier settings: On iPhone, go to Settings > General > About and wait for a prompt. On Android, go to Settings > About phone > Software updates.
• Contact your carrier to confirm your plan includes 5G and that your SIM is provisioned for 5G.

5G is on but no connection

• Toggle Airplane mode on and off to force a network re-registration.
• Restart your phone.
• Reset network settings: On iPhone, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. On Android, go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. Note: this will erase saved Wi-Fi passwords and Bluetooth pairings.
• Check if 5G works in a different location — you might be in a dead zone.
• If you’re using a VPN, try turning it off — some VPNs interfere with 5G connectivity.

5G shows but internet is slow

• You might be on 5G “low-band” which is slower than mid-band or mmWave. Look for “5G UW” (Verizon), “5G+” (AT&T), or “5G UC” (T-Mobile) in the status bar — those indicate faster variants.
• Move near a window or go outside if you’re indoors — 5G signals don’t penetrate walls as well as 4G.
• Check if your data plan has a speed throttle after a certain amount of usage.

Battery drains fast with 5G

• Switch to 5G Auto on iPhone or select LTE when you don’t need high speeds.
• On Android, you can set the network mode to LTE temporarily, or use a battery saver mode.

Frequently Asked Questions

Do I need a special SIM card for 5G?

Most newer SIM cards support 5G, but if your SIM is more than a few years old, it might not. Contact your carrier to check or get a free replacement.

Will 5G use more data?

5G itself doesn’t use more data, but because it’s faster, you might stream higher-quality video or download larger files, which can increase data usage. Your plan’s data allowance applies the same way as 4G.

Why do I see “5G” but can’t make calls?

Some phones use 5G for data and fall back to 4G for calls (VoLTE). If VoLTE is disabled, calls may fail. Check that VoLTE is enabled in your network settings, or contact your carrier.

Can I force my phone to use 5G only?

On most phones, you can select a “5G only” mode, but it’s not recommended because you’ll lose connection if 5G isn’t available. It’s usually hidden in developer options on Android. On iPhone, there’s no 5G-only option — you can only choose 5G Auto or 5G On.

Does 5G work internationally?

5G works in many countries, but you need a plan that includes international roaming with 5G access. Check with your carrier before traveling.

Why is my 5G slower than 4G?

You might be on a low-band 5G signal, which is slower than mid-band or mmWave. Also, network congestion can slow speeds. Check the status bar icon — if it shows “5G” without any suffix, it’s likely low-band.
