/ SIM & Network Help

Independent UK Mobile SIM & Network Diagnostics

Dead SIM, failed port, or signal black spot? We diagnose the specific fault — not the category — and tell you exactly what to do next.

— Three distinct paths

We identify the fault before we suggest a fix

SIM Not Recognised

PAC Codes & Port Delays

Network Faults vs. Handset Faults

We check whether the fault is the SIM itself, the tray, or the handset's SIM reader — three different problems with three different fixes.

Porting delays and PAC code failures follow predictable carrier timelines. We track where yours is stuck and advise the correct escalation step.

If the problem is a genuine network outage or coverage gap, we say so directly and point you to the right escalation — not a generic help page.

• Common questions

SIM & network — straight answers

My SIM says 'No Service' — what's happening?

Can you tell if a coverage issue is my handset or the network?

It could be the SIM, the tray, or a local outage. We ask three specific questions to rule out each cause before recommending any action.

Yes. We check known outage data and run through handset-specific diagnostics. Most customers find out within minutes whether it's their device or the mast.

How long should a PAC code transfer take?

Do I need to contact my carrier first?

UK regulations require completion within one working day of the receiving network activating the request. If yours has stalled beyond that, there is a specific escalation path.

No. Contact us first. We can tell you whether the issue needs carrier involvement at all — and if it does, exactly what to say when you call them.

Know the fault. Know the fix.
