iPhone No Service and WiFi faults — when it isn't the network.
Once a new SIM, carrier settings and a reset have changed nothing, a permanent No Service or greyed-out WiFi is usually the radio hardware itself. On iPhones these are board-level circuits — baseband and RF for cellular, a dedicated module for WiFi and Bluetooth — and they are diagnosable and frequently repairable.
The fixed £35 diagnostic covers the assessment described below and both-way UK tracked shipping. If you approve the repair quote, the fee is deducted from that quote. No repair work starts without your approval.
The symptom
Radio symptoms that point to hardware
These patterns survive every software fix, which is the tell:
- Permanent No Service or endless Searching, with a known-good SIM
- WiFi toggle greyed out, or Bluetooth unavailable in settings
- No IMEI or modem firmware shown in Settings → General → About
- Signal died after a drop, liquid exposure, or has always been weak since a repair
Likely causes
What breaks the radios
Baseband circuit faults
The cellular modem and its power/communication lines are classic failure points after drops — a missing IMEI is the strong signature.
WiFi module failure
A greyed-out WiFi toggle usually means the module is not answering at all — a hardware fault, not a settings problem.
Corrosion on RF paths
Liquid exposure degrades the delicate RF section progressively — weak signal that worsens over months is the classic story.
Board flex and previous repairs
On some models board flex from drops cracks the layered connections under the radio ICs — a fault only board-level rework addresses.
What the diagnostic finds
What the £35 assessment actually does.
- IMEI and modem-presence checks to separate baseband failure from RF path damage
- Radio power-rail and communication-line testing under magnification
- Antenna path and connector inspection — the honest cheap fix when it applies
- A written finding on repair viability, because some baseband faults are not economical — you will be told that plainly
The findings arrive in writing with the quote. You approve, decline or extend — the fee terms are explained in the FAQ.
Describe the fault once — then approve the next step.
The booking form records what happened so the bench sees the same details. Completed repairs carry a 90-day warranty on the specific fault repaired.

iPhone other FAQ
I've already tried a new SIM and a reset. What's left?
Hardware. Once software and SIM are ruled out, No Service is a board-level candidate — and the diagnostic will show quickly whether the modem is present, powered and answering.
Is WiFi greyed out the same fault as No Service?
Different circuits, same category. Greyed-out WiFi points at the WiFi/Bluetooth module; No Service points at baseband. Both are board-level diagnoses, and both are covered by the same £35 assessment.
Is this kind of repair always viable?
Not always — some radio faults sit in components that are not economically repairable, and we will say so in the written findings rather than attempt speculative work. The diagnostic fee buys you a straight answer either way.
