Cause — a setting vs the network
A setting
Most reported complaints close here, usually within the first two adjustments.
- Wi-Fi Calling off
- 4G Calling off after the 3G withdrawals
- Stale connection to a distant mast
- Pending updates
VS
The network
Mast maintenance, a local fault, or congestion at peak hours.
- Affects a whole area
- Shows on the status page
- No handset adjustment helps
Which wins, and for whomWork down six adjustments first, then check the status page with your postcode. Buying a new handset to solve a settings problem is the most common expensive mistake in this subject.

Call 020 3896 5248WhatsApp usResponse — telephoning vs writing
Telephoning
Immediate, and sometimes resolves simple issues on the spot.
- Fast for straightforward problems
- Leaves no file
- Nothing to escalate with
VS
Writing
App transcript, email or letter with dates, facts and the outcome sought.
- Creates a reference
- Reviewable by an ombudsman
- Slower to start
Which wins, and for whomWrite, and keep the reference. A dated file is what wins a goodwill credit; persistence on the phone is not.
The six adjustments, in order
FirstWi-Fi Calling on — calls travel over your broadband and walls stop mattering
Second4G Calling (VoLTE) on — essential since 3G closed on every UK network
ThirdTen seconds of airplane mode — forces a fresh connection to the healthiest mast
FourthInstall pending handset and carrier updates
FifthMove a metre, ideally toward a window
SixthCheck the network status page with your postcode
Reading the symptom
Area dead for hoursMast maintenance or fault
Full bars, nothing loadingCongestion — capacity, not coverage
Older handset failing callsThe 3G withdrawals of 2024 and 2025
One room, alwaysBuilding materials
Intermittent odditiesEngineering works, including consolidation activity
Claiming for an outage
Log dates, times, postcode and what failed for a fortnight, report in writing once service returns with the log attached, and ask specifically what goodwill applies to the recorded period.
Sustained or repeated loss of service is where credits get agreed. Refused after a fair log, eight weeks unresolved or a deadlock letter opens free escalation to the Communications Ombudsman.
