Galaxy S22 keeps dropping calls: fix the cause fast

If your Galaxy S22 drops calls on one SIM only, the problem is usually the SIM, eSIM, or carrier line; if it happens on every SIM and in every location, suspect the phone or its modem. Miss that split, and you can waste time on the wrong fix or replace hardware that is fine. This guide shows a fault-isolation flow to separate S22, SIM/eSIM, carrier, and local-network causes.

What dropped calls on a Galaxy S22 usually mean

On a Galaxy S22, a dropped call is usually a mid-call disconnect, one-way audio that ends in a disconnect, or a call that fails when the phone switches between LTE, 5G, Wi‑Fi Calling, or Bluetooth audio. Your first check is simple: make one call with Bluetooth off and Wi‑Fi Calling off, then compare it with a call in a second location.

The Galaxy S22 family includes carrier-locked and unlocked models, and regional hardware matters: the US model uses Qualcomm Snapdragon 8 Gen 1, while the UK and other regions use Samsung’s Exynos chip. The standard Galaxy S22 has a 6.1-inch screen, ships with 8GB of RAM, and offers up to 256GB of storage.

That matters because call behavior can change with modem firmware, baseband version, carrier provisioning, and how the phone handles handoff between LTE, 5G, and Wi‑Fi Calling. Samsung Support also separates help into categories such as Call & Contacts, Network & WiFi, Software Upgrade, Reset, and Power issues.

Likely causes, ranked from most to least common

Most often, dropped calls trace back to weak or unstable coverage, poor handoff between LTE and 5G, or a carrier outage. Less commonly, the cause is SIM, eSIM, or account provisioning, then call-setting conflicts or Bluetooth/Wi‑Fi Calling behavior, and finally a software or baseband regression after an update.

• Weak or unstable coverage near one tower, inside one building, or during LTE/5G switching.
• Carrier-side problems such as outages, missing VoLTE support, or bad line provisioning.
• SIM or eSIM issues including a damaged tray, a stale eSIM profile, or an account flag.
• Settings conflicts involving Wi‑Fi Calling, preferred network mode, blocked numbers, or call forwarding.
• Accessory interference from Bluetooth headsets, car kits, or speakerphone routing.
• Software or modem firmware issues after a One UI, security patch, or carrier update.

Is it my carrier or my phone if calls keep dropping?

It is usually the carrier or line provisioning if the same SIM drops calls in one area, but works elsewhere, while the phone behaves normally with another line. It points to the phone if every SIM, every location, and every call mode fails the same way. Test one factor at a time.

Test one SIM at a time on dual-SIM setups

1. Go to Settings > Connections > SIM manager.
2. Turn off one line so only one SIM or eSIM is active.
3. Place a short call on the active line.
4. Repeat with the other line active only.
5. If one line fails and the other does not, contact the carrier for that line’s reprovisioning or replacement.

Test the same call in two locations

1. Make a call in your usual problem location.
2. Repeat the same call outdoors or near a known strong-signal area.
3. If the issue appears only in one place, suspect coverage, congestion, or handoff failure.
4. If it happens everywhere, move to SIM, eSIM, or device-side checks.

Compare cellular-only calls with Wi-Fi Calling

1. Open Settings > Connections > Wi-Fi Calling and turn it off.
2. Place one call on mobile network only.
3. Then turn Wi-Fi Calling on and make the same call again.
4. If calls fail only on cellular, the carrier radio path is more suspect than the phone app.
5. If calls fail only on Wi-Fi Calling, check your router, captive portal, or carrier VoWiFi support.

Check signal, network mode, and call handoff

Does weak signal cause dropped calls on Samsung S22? Yes, but only when the signal is unstable enough to break the voice path or a handoff fails during a switch from LTE to 5G or back again. The key check is whether dropping stops when you force a simpler network path.

Switch between LTE and 5G to see if drops stop

1. Go to Settings > Connections > Mobile networks > Network mode.
2. Select an LTE-only option if your carrier allows it.
3. Make a test call.
4. If the drops stop on LTE, the issue may be 5G handoff or tower behavior.
5. Switch back to your normal mode after testing.

Confirm VoLTE and Wi-Fi Calling are enabled

1. Open Settings > Connections > Mobile networks.
2. Turn on VoLTE calls or HD Voice if shown.
3. Open Settings > Connections > Wi-Fi Calling and enable it for testing.
4. If your carrier blocks VoLTE on the line, ask for provisioning support.

Check whether calls fail only on speakerphone or Bluetooth

What if calls drop only on speakerphone or Bluetooth? That usually points to audio-routing or accessory behavior, not signal loss. A common first-timer mistake is blaming reception when the call stays connected but audio changes hands between the phone, headset, and car kit.

1. Make one call with Bluetooth off and speakerphone off.
2. Repeat with speakerphone on and Bluetooth still off.
3. Repeat with Bluetooth on and all accessories disconnected except the phone.
4. If only one mode fails, repair or remove the accessory pair in Settings > Connections > Bluetooth.

Fix SIM card or eSIM problems

Should I replace my SIM card if my S22 keeps dropping calls? Replace it if the card is worn, the tray does not sit flush, or the same line still fails after a reseat. For eSIM, the equivalent fix is often a carrier reissue or profile download, especially when only one active profile misbehaves.

Reseat and inspect a physical SIM and tray

1. Power off the phone.
2. Remove the SIM tray and inspect it for bending, debris, or poor fit.
3. Check the SIM for scratches, cracks, or dull contacts.
4. Reinsert the SIM with the tray seated fully.
5. If the problem remains, ask the carrier for a replacement SIM and reprovisioning.

Check the active eSIM profile and line selection

1. Go to Settings > Connections > SIM manager.
2. Confirm the correct eSIM line is set as active for calls.
3. Disable the other line and retest.
4. If the call path improves, the old profile may be stale or misprovisioned.
5. Delete and re-download the eSIM only if the carrier gives a fresh activation code.

Ask the carrier to reprovision or replace the line profile

1. Request a line refresh for VoLTE, 5G, and Wi‑Fi Calling.
2. Ask whether the account has any call-blocking, fraud, or roaming flags.
3. Have the carrier confirm the line is active on the correct device IMEI.
4. If needed, request a new SIM or a new eSIM activation.

Will resetting network settings fix dropped calls on Galaxy S22?

Yes, sometimes. A network settings reset can clear bad Wi‑Fi, Bluetooth, and mobile configuration data that interferes with calls, but it does not wipe apps, photos, or accounts. Use it after you have ruled out one-location coverage problems and one-SIM or one-profile failures.

What the reset clears and what it leaves alone

1. Go to Settings > General management > Reset > Reset network settings.
2. Confirm the reset.
3. It clears saved Wi‑Fi networks, Bluetooth pairings, and mobile network preferences.
4. It generally should not erase personal data or perform a full factory reset.

What to reconfigure right after the reset

1. Reconnect to Wi‑Fi with the password.
2. Re-pair Bluetooth headsets or car kits if needed.
3. Turn on VoLTE and Wi-Fi Calling again if your carrier uses them.
4. Recheck Settings > Connections > Mobile networks for the correct network mode.

Can a software update fix call drops on Galaxy S22?

Yes, if the drop started after a bug fix was needed in the modem stack, One UI, or carrier settings package. Check the One UI version, security patch level, and baseband version first, then compare behavior before and after the update. If the issue began right after updating, treat the update as a possible cause too.

Check One UI version, security patch level, and baseband

1. Open Settings > About phone > Software information.
2. Note the One UI version, Android version, Security patch level, and Baseband version.
3. Compare that with the time the call drops started.
4. If a recent update coincides with the problem, a carrier patch or later fix may be needed.

What to do if the problem started after an update

1. Restart once after the update to let carrier components settle.
2. Test the same call on LTE-only and then with Wi-Fi Calling.
3. Check for a newer software update under Settings > Software update > Download and install.
4. If the baseband changed and the drops began immediately after, contact the carrier and Samsung support with the version details.

What to try if calls still drop

If that did not work, move up the escalation ladder: verify a carrier outage, ask for VoLTE and line reprovisioning, then remove Bluetooth accessories and car kits from the test path. If the problem persists across SIMs, locations, and network modes, Samsung service is the next step.

Say your S22 drops every call in the same office building but works outside. That points to coverage or congestion first. Suppose a dual-SIM phone drops only on the eSIM line after a recent activation. That points to a bad profile, not a dead modem.

A practical prevention step is to keep Wi‑Fi Calling, VoLTE, and the preferred network mode set the same way after carrier changes, then retest after any software update that changes the baseband or carrier package.

Frequently asked questions

why does my samsung phone keep dropping calls

The usual causes are weak signal, a carrier outage, a bad SIM or eSIM profile, or a network-setting conflict. Start with Settings > Connections > Mobile networks, then compare one location, one SIM, and one call mode at a time so you can separate phone-side from carrier-side failures.

Why does my Galaxy S22 keep dropping calls?

The S22 may be switching poorly between LTE, 5G, and Wi‑Fi Calling, or one line may be misprovisioned. Check Settings > Connections > SIM manager, then test LTE-only, Wi‑Fi Calling, and Bluetooth-off calls. If one mode fails consistently, that mode is the clue.

How do I stop my Samsung Galaxy S22 from dropping calls?

Use a simple order: test another location, switch to LTE-only, confirm VoLTE and Wi‑Fi Calling, reseat the SIM or refresh the eSIM, then reset network settings. If drops still happen on every SIM and network mode, ask Samsung or the carrier to inspect the modem and account provisioning.

Do eSIM settings affect dropped calls on Galaxy S22?

Yes. An inactive line, stale profile, or wrong active SIM selection can route calls badly or fail outright. Check Settings > Connections > SIM manager, confirm the correct line is active, and ask the carrier for a fresh eSIM activation if the problem stays tied to that profile.
