How does it work?
We give you a local UK number — your “PhoneGuernsey Number”. Whenever you’d normally dial a Guernsey number, you ring your PhoneGuernsey Number instead, and we connect the call to the Island over our own network. Because you’re ringing a UK number, it’s included in your mobile plan, and you only pay our low per-minute rate for the Guernsey leg.

Frequently asked questions
Still unsure if PhoneGuernsey is right for you? Here are the questions we’re asked most.
How can you offer cheap calls to Guernsey?
Instead of dialling a Guernsey 01481 landline or mobile directly, you ring a local UK number we give you — so the call is “in bundle” with your UK mobile provider. We then route it on to Guernsey over our own network at a fraction of what UK mobile networks charge, so you pay just 5p/min to landlines and 15p/min to mobiles.
How does billing work?
It’s pay as you go. You top up credit (from £10), and calls are deducted at 5p/min for Guernsey landlines and 15p/min for Guernsey mobiles. A £1/month service charge keeps your number active. You can top up any time, or turn on auto top-up so you never run out mid-call.
Do I have to change my mobile provider?
No. You ring your PhoneGuernsey Number from any UK network — nothing changes about your existing mobile plan.
Can I call more than one Guernsey number?
Each PhoneGuernsey Number forwards to one Guernsey number at a time, but you can change which number it rings yourself — landline or mobile — any time from your account dashboard, in seconds. If you regularly call several Guernsey numbers and want them all live at once, just add a PhoneGuernsey Number for each.
Does my credit expire?
Your credit stays on your account while it’s active. The £1/month service charge is taken from it to keep your number live. If your balance runs out and isn’t topped up, your number is eventually released.
Can I cancel?
Yes, any time — there’s no contract. You can close your account yourself from your dashboard; your number stops and is released. Any remaining credit is non-refundable.
Why is it so expensive to ring Guernsey?
Guernsey is a Crown Dependency, so UK mobile providers treat calls to Guernsey landlines and mobiles much like international calls — leaving them out of bundle and charging upwards of 65p per minute.
Who is PhoneGuernsey?
PhoneGuernsey is part of ONSIM — a UK telco specialising in next-generation business mobiles and VoIP phones. We built PhoneGuernsey to make calling Guernsey affordable, connecting you for a fraction of what the UK networks charge.
