5G Not Working on Android: How to Fix (Full Guide)

by

If you searched for 5G Not Working on Android: How to Fix, you’re in the right place. This education‑first guide walks you through fast, safe fixes for missing 5G, dropping to LTE, slow NR speeds, or “5G” showing but doing nothing. We start with a two‑minute triage, then move into coverage checks, SIM and plan verification, network settings, APN resets, dual‑SIM quirks, Android 15 changes, advanced diagnostics, and when to call your carrier. Every section is practical and vendor‑agnostic so you can fix 5G on Pixel, Samsung, OnePlus, Motorola, and more—with clear links to official references.

How to Fix 5G Not Working on Android?

Before deep dives, run these fast checks. They fix a surprising number of 5G issues caused by stale radio states or post‑update quirks.

  1. Toggle Airplane Mode for 15–20 seconds. This hard‑resets modem attach and re‑registers on 5G if available.
  2. Reboot the phone. Pending carrier config or Play system updates apply on restart.
  3. Move outdoors or to a window. 5G—especially mid‑band/mmWave—doesn’t love basements or thick walls.
  4. Disable Battery Saver/Data Saver temporarily. Some OEMs throttle background network attach under aggressive power modes.
  5. Swap SIM slots (physical SIM) or toggle your data SIM (dual‑SIM) to refresh attach priorities.

Airplane Mode and a quick network‑type toggle often restore 5G by forcing a fresh attach to the network.

What You Need for 5G to Work

5G requires three things to line up. Miss any one, and your phone falls back to LTE.

  • Device support: Your model must support the carrier’s 5G bands (n71, n41, n77, n258, etc.) and 5G modes (NSA/SA) used in your region. Imported phones can miss key bands or carrier whitelists.
  • Plan provisioning: Your line must include 5G access. Older plans sometimes exclude 5G until you switch or ask support to add it.
  • Coverage: Your tower must broadcast 5G where you stand. 5G indicators can “stick” after moving; force a re‑attach (Airplane Mode) to confirm.

To understand why matching bands/modes matters, see 3GPP’s 5G overview: 3GPP: 5G.

Coverage and Outage Checks (Before You Tweak)

Don’t chase settings if the network is down or you’re outside 5G coverage.

  • Official coverage maps: For the U.S., check the FCC’s Mobile Coverage Maps to sanity‑check carrier footprints: FCC Mobile Coverage.
  • Carrier status pages: Search “[Carrier] service status” or use widely used outage aggregators (compare across multiple sources for confidence).
  • Try another known 5G area: If you get 5G at a mall or downtown but not at home, you’re likely at the edge of a cell (or on a different band).

Coverage confirmed? Move on to settings.

Android Settings to Verify (Step by Step)

Names vary slightly by OEM, but the flow is similar on all Android phones.

  1. Preferred Network Type: Settings → Network & Internet → SIMs → Preferred network type → choose 5G (Auto) or 5G/4G/3G (Auto). If 5G is flaky in your area, test LTE temporarily, then switch back.
  2. Mobile Data: On. Data Saver Off (for testing). Roaming On only when traveling.
  3. VoLTE/Wi‑Fi Calling: On if supported (helps attach stability and voice on 5G SA networks).
  4. Carrier Settings: Some devices show “Carrier settings update” or “Carrier services” in Cellular settings—apply if available.
  5. SIM Data Line (Dual‑SIM): Ensure the SIM with 5G is set as the Mobile data SIM. Many devices allow 5G on one line at a time.
  6. Private DNS/VPN: Disable temporarily (Settings → Network & Internet) to rule out DNS/VPN profiles that can block IMS/5G signaling.

APN, Carrier Services, and Network Resets

Wrong APN or stale radio configs = no 5G. Fix in this order.

  1. Update apps + Google Play system: Play Store → Manage apps → Update all. Then Settings → Security & privacy → Updates → Google Play system update.
  2. Update/clear Carrier Services: Play Store → Carrier Services → Update. If broken, Settings → Apps → Carrier Services → Storage → Clear cache/data → reboot (it will re‑provision).
  3. Reset APN to default: Settings → Network & Internet → SIMs → Access Point Names → 3‑dot menu → Reset to default. Avoid random APN lists—use default or your carrier’s official APN page.
  4. Reset Network Settings: Settings → System → Reset options → Reset Wi‑Fi, mobile & Bluetooth. Reboot, then re‑add Wi‑Fi and BT devices. This resolves many post‑update modem quirks.

SIM and eSIM: Provisioning, Swaps, and Dual‑SIM Quirks

Provisioning is the hidden culprit behind many “5G missing” reports.

  • Confirm 5G on your line: Contact your carrier or check your online account. Ask: “Is 5G provisioned on this line and IMEI?”
  • Update IMEI on account: If you swapped phones or used an older IMEI, carriers may keep you on a non‑5G profile. Ask support to update the IMEI they have on file.
  • Re‑download eSIM: Delete and re‑add eSIM from carrier’s app or QR code. This refreshes the carrier profile and IMS/NR capabilities.
  • Dual‑SIM limitations: Many phones allow 5G on only one SIM at a time. Set the 5G line as the Mobile data line; toggle “Allow 5G on secondary SIM” (OEM‑specific) if present.

5G Basics That Affect Real‑World Fixes (NSA, SA, Bands)

Knowing a few 5G terms helps you troubleshoot intelligently:

  • NSA vs SA: Non‑Standalone (NSA) uses LTE as the anchor; Standalone (SA) uses a 5G core (VoNR may be required for voice). Your carrier may enable one, the other, or both. Some devices need a carrier config update to attach to SA.
  • Bands and flavors: Sub‑6 GHz (e.g., n71, n41, n77) goes farther; mmWave (n258/n260/n261) is ultra‑fast but very short‑range and line‑of‑sight.
  • Icons lie: A “5G” icon can represent low‑band that’s similar to LTE speeds. Test throughput before assuming it’s broken.

VoLTE/VoNR, Wi‑Fi Calling, and IMS Dependencies

Voice over LTE (VoLTE) and Voice over NR (VoNR) influence whether your phone stays on 5G or falls back for calls.

  • Enable VoLTE/Wi‑Fi Calling: Keeps data on 5G during calls (NSA) and permits SA/VoNR attachment where supported.
  • IMS provisioning: Some carriers tie 5G access to IMS success. If Wi‑Fi Calling refuses to enable, fix that first (APN reset, carrier re‑provisioning).
  • Remove call‑filter/VPN temporarily: Over‑aggressive call filters can block IMS registration.

After Android 15 Update: What to Recheck

Major updates can reset radio defaults or introduce temporary modem bugs.

  • Re‑verify Preferred network type, VoLTE/Wi‑Fi Calling, and Data Saver/Battery Saver toggles.
  • Apply all Google Play system and carrier updates; reboot afterward.
  • If 5G is still unstable, Reset network settings, then test in Safe Mode to rule out third‑party apps that modify DNS/VPN.

If battery life also went sideways post‑update, tightening network and background behavior helps. See our complementary guide: Android 15 Battery Drain: Quick Fixes Guide.

VPN, Private DNS, and Enterprise Profiles

Security tools can quietly break 5G attach or IMS.

  • Turn off Private DNS (Settings → Network & Internet) or set to Automatic for testing.
  • Disable VPN temporarily. Some VPNs block IMS/voice registration or keep radios in a power‑hungry state.
  • Work profiles/MDM: Enterprise policies may force specific APNs or block Wi‑Fi Calling. Test on a personal profile or ask IT to review.

Advanced Diagnostics: Field Info, *#*#4636#*#* (where available), and Logs

Use these tools to see what the modem is actually doing.

  • Field test/service mode: Many OEMs provide a cell info page (bars menu or dialer code) that shows NR/LTE bands, NSA/SA status, signal strength (RSRP/RSRQ/SINR). If you see LTE only in a 5G area, the device isn’t attaching—suspect SIM provisioning or bands.
  • *#*#4636#*#* (not on all devices): Phone information → Set Preferred network type. Avoid “NR only”—you’ll lose service outside 5G.
  • Carrier escalation: Provide time, location (cross streets), and screenshots of signal metrics when calling support. Ask them to refresh provisioning and confirm 5G on your IMEI and plan.

Roaming/Travel: Manual Selection and Band Mismatch

Abroad, your 5G depends on roaming agreements and bands.

  • Manual network selection: Settings → Network & Internet → SIMs → Network → Search networks → pick a 5G‑capable partner.
  • Turn off 5G if it hunts: In fringe areas, prefer LTE for stability; switch back in cities with strong 5G.
  • International plans: Confirm your plan includes 5G roaming; many default to LTE abroad.

Hardware Red Flags and When to Escalate

Sometimes, it’s the phone.

  • Recent drop or water exposure: Antenna damage can break 5G bands but leave LTE working.
  • Only certain bands fail: If low‑band 5G works but mid‑band/mmWave never attach in known coverage, suspect hardware or model limitations.
  • Try another SIM (same carrier) or put your SIM in another 5G‑capable phone. If your SIM works elsewhere, your phone likely needs service.

If 5G Shows but Feels Slow

Being on 5G doesn’t guarantee speed. Try this:

  • Test servers and bands: Run multiple tests (different times and servers). Congestion varies. Low‑band 5G can equal LTE speeds.
  • Prefer Wi‑Fi for downloads: For large updates, use Wi‑Fi to avoid tower congestion.
  • Disable battery/data saver and ensure VPN is off for testing. Some VPNs throttle or reroute traffic internationally.

10‑Step Cheat Sheet (Copy/Paste)

  1. Toggle Airplane Mode 20s → Off; reboot.
  2. Move to a window/outdoors; confirm you’re in a 5G area (FCC map for U.S.).
  3. Settings → Network → Preferred network type → 5G (Auto); Data Saver Off (test), Private DNS Off (test).
  4. Enable VoLTE and Wi‑Fi Calling; reboot.
  5. Update apps + Google Play system; update/clear Carrier Services; reboot.
  6. Reset APN to default; if custom APN required, use official carrier values only.
  7. Reset Network Settings; re‑add Wi‑Fi/BT; reboot.
  8. Confirm 5G provisioning on your plan + IMEI with carrier; re‑download eSIM if needed.
  9. Dual‑SIM: set the 5G line as the data SIM; test with second SIM off.
  10. If still broken: test another known 5G location, try another SIM/phone, then escalate to carrier with logs/screens.

FAQs

Why did 5G vanish after an update?

Major updates can reset radio defaults or break old Carrier Services data. Update everything, reset APN/network, and re‑enable VoLTE/Wi‑Fi Calling.

My plan says 5G is included—why no 5G?

Carriers also need your IMEI provisioned for 5G. Ask support to refresh provisioning or update IMEI on file.

Can Private DNS or VPN block 5G?

They can block IMS/registration. Disable while testing.

Is “5G” always faster than LTE?

Not necessarily. Low‑band 5G may be similar to LTE. Mid‑band and mmWave are where you see big gains.

Does 5G drain battery faster?

In weak coverage, yes—tower hunting burns power. Prefer Wi‑Fi, use 5G Auto, or LTE in fringe zones. For broader tips, see our Android 15 battery guide above.

Verdict

Fixing “5G Not Working on Android” is usually about alignment: the right plan and provisioning on your IMEI, coverage in your location, and clean Android settings/APN. Start with quick resets and official updates, reset APN/network, make sure VoLTE/Wi‑Fi Calling and 5G Auto are on, then confirm 5G is provisioned on your account. If dual‑SIM is involved, set the correct data line. When in doubt, capture screenshots of signal and settings, and ask carrier support to refresh provisioning. With the steps above—and a little patience—you’ll restore 5G and keep it stable.
