FAQs — Cardiff
Can I keep my Cardiff phone number?
Yes. We port Wales landline and mobile numbers free on Plus and above, typically within 24 hours via the PAC/STAC process. Existing 029 numbers move across without losing a call.
When does the PSTN switch off for Cardiff?
BT Openreach is retiring the UK PSTN (WLR2) nationally on 31 January 2027. Many Openreach exchanges serving Cardiff are already on stop-sell, so analogue lines can no longer be ordered there — migrating early avoids a rushed cut-over.
Is Silux Call regulated in the UK?
Silux Call is operated by Silux Telecom Ltd, registered in England & Wales, and UK business telephony is regulated by Ofcom. That framework is what sets your right to keep your number when you switch (via the PAC/STAC process), the rules on emergency 999/112 access from a VoIP line, and the complaints route we publish in our Complaints Code of Practice. Silux Call follows Ofcom's General Conditions of Entitlement for Cardiff customers as for every other UK location.
Can I call 999 from a VoIP phone in Cardiff?
Yes. Emergency calls to 999 and 112 work from Silux Call, and we hold the Cardiff service address you register so emergency operators receive a location. Because a VoIP line depends on power and broadband, Ofcom expects providers to be clear about that: keep a charged mobile as a backup for a power cut, exactly as you would with any internet-based phone service.
What does business VoIP cost in Cardiff?
Silux Call has a permanently free seat, Pay-as-you-go at £0.02/min UK landline, and paid plans from £6.95/user/month, all billed in GBP with no contract. There is no premium for Cardiff or any other UK location.
Do I need new phones for my Cardiff office?
No. Silux Call runs on the mobile, desktop and web softphone, so existing computers and smartphones work immediately. IP desk phones are optional and provisioned automatically if you want them.
Can Cardiff businesses get a local 029 number?
Yes. New 029 area-code DDIs are provisioned in seconds, or you can port your existing Cardiff number for free on Plus and above.
Can I get a free phone number in Cardiff?
Yes. Silux Call's permanently free seat includes one free UK number — a local 029 Cardiff number or an 03 number — with free voicemail-to-email and call divert, no card required. You get 30 outbound minutes a month free; add more numbers from £1/month.
