What to do if…
your phone shows emergency-calls-only or no service when you know coverage is normal

Short answer

Move to a clear spot, toggle Airplane Mode on for at least 15 seconds and off again, then restart once. If the phone still shows emergency-calls-only, use Wi-Fi or another phone and contact your mobile network to check outages, account bars, and SIM or eSIM provisioning.

Do not do these things

Do not factory reset your phone as a first move; it erases data and can create account-access problems.
Do not delete your eSIM unless your mobile network tells you to.
Do not keep restarting repeatedly for hours; do a few deliberate checks, then switch to Wi-Fi or another phone.
Do not change APN or network settings from random forum posts.
Do not assume your number has been stolen just because service vanished; this can also be a SIM, eSIM, account, handset, or network-registration problem.
Do not wait if you need urgent help or a time-sensitive call today; use another phone or trusted Wi-Fi now.

What to do now

If you need emergency help, try 999 or 112 first.
In the UK, 999 and 112 reach the emergency services. A mobile may be able to use another available UK mobile network for an emergency call, but it cannot make the call if no mobile network is reachable. If the call will not connect, use another phone immediately.
Move to a known-good signal spot for 2 minutes.
Go outside or near a window, away from lifts, basements, thick walls, and underground areas.
Force the phone to reconnect to the mobile network.
Turn Airplane Mode on for at least 15 seconds, turn it off, then wait. If nothing changes, restart the phone once.
Check the correct SIM or eSIM line is switched on.
On dual-SIM phones, open Mobile or Cellular settings and check that the line for your number is turned on. If the phone has separate settings for calls, texts, and mobile data, check the correct line is selected.
Try manual network selection once, then return to automatic.
In Mobile or Cellular settings, turn off automatic network selection, wait for the network list, and choose your provider. If it fails or hangs, turn automatic selection back on.
Do one safe SIM or eSIM check.
For a physical SIM, power the phone off, remove the SIM, check for obvious damage or poor fit, reinsert it firmly, then power on. For an eSIM, toggle the eSIM line off and on; do not delete it unless your network tells you to.
Use Wi-Fi for urgent communication.
Join trusted Wi-Fi. Use email or a messaging app if SMS is not arriving. Turn on Wi-Fi Calling if your phone, account, and network support it.
Check for updates without doing a wipe.
On Wi-Fi, install any pending phone system update. On iPhone, check for a network provider settings update by going to Settings, General, About and following any prompt.
Check your account using Wi-Fi or another device.
Open your mobile network’s app or account page and look for service suspension, billing problems, reported lost or stolen status, SIM swap messages, or a recent SIM or eSIM change you did not request.
Contact your mobile network and ask for specific checks.
Say: “My phone shows emergency-calls-only in an area where coverage is normally fine. I have toggled Airplane Mode, restarted, checked the SIM or eSIM line, and tried network selection.” Ask them to check:

local outage or maintenance
whether the account or line is barred
whether the SIM or eSIM is active and provisioned correctly
whether there has been a SIM swap or line change
whether the handset is blocked on the network

Use another phone for non-emergency police contact if needed.
For police non-emergencies in the UK, use 101 from another working phone.

What can wait

You do not need to decide today whether to change network, change number, or buy a new phone.
You do not need to factory reset the phone, delete the eSIM, or install network-tweaking apps.
You do not need to find the perfect diagnosis now. The immediate goal is to restore basic calling, texts, or data, or to get a temporary route through Wi-Fi or another phone.

Important reassurance

Emergency-calls-only often means the phone is not registering normally with your mobile network, not that everything on the phone is broken. A small number of targeted checks, followed by a clear call to your network, is safer than repeated tinkering.

Scope note

These are first steps only, to stabilise access to calls, texts, and data. Later decisions, such as replacing a SIM, reissuing an eSIM, repairing the handset, or changing network, may need help from your mobile network, device maker, or a repair professional.
