Calls to mobiles — one honest rate, every UK network
Rated 5 stars by 271 business customers on Trustpilot.
Pick up a business phone bill and run a finger down the itemised calls: the lines that sting are almost never landline-to-landline. They're calls to mobiles. Customers answer on mobiles, suppliers answer on mobiles, your own engineers and reps are on mobiles — and retail providers price accordingly. We route those same calls at wholesale rates instead: from 8p per minute to every UK mobile network, billed per second after the first minute, on the same lines and phones you already have. UK Wholesale has supplied business telecoms since 2005, on the same Openreach infrastructure the big retailers use — without the retail margin, and with experts you can actually speak to.
What calling mobiles costs
- One flat rate to all UK mobile networks — from 8p per minute. EE, O2, Vodafone, Three, and the virtual networks that run on top of them, all priced the same.
- No 'all major networks except…' small print. If it's a UK mobile number, the rate applies. You never need to know which network the person you're calling happens to be on.
- Per-second billing after the first minute. A ninety-second call is billed as ninety seconds — not rounded up to the next whole minute.
- Heavy mobile caller? Capped and inclusive packages take it further — calls capped at 20p for up to an hour.
Why calls to mobiles quietly dominate business phone bills
Landline-to-mobile is where retail call pricing does its quiet work. Three things stack up against you:
- Mobile rates carry the biggest margin. Calls to mobiles cost providers more to terminate than landline calls — and retail tariffs add their own healthy mark-up on top. That mark-up is the part wholesale routing removes.
- Most of your calls now end on a mobile. The way Britain answers the phone has changed: customers, tradespeople, couriers, sales contacts — the number you're given is a mobile number. A rate that only looked "occasional" a decade ago now prices most of your outbound calling.
- The pricing hides in the small print. Rounded-up minutes, different rates for different networks, "inclusive" allowances that exclude the calls you actually make — retail mobile pricing is built to be hard to compare. One flat per-second rate is built to be easy.
None of this needs a new phone system to fix. It needs the same calls routed over wholesale agreements instead of retail ones — which is the entire service.
Retail mobile pricing vs one wholesale rate
| Typical retail | UK Wholesale | |
|---|---|---|
| Rate to UK mobiles | The "out of plan" rate, buried in the tariff | From 8p per minute |
| Networks covered | Often "all major networks" — with exceptions | Every UK network, one rate |
| Billing increments | Often rounded up to the next minute | Per-second after the first minute |
| Long calls | The meter just keeps running | Package option: capped at 20p for up to an hour |
| Against standard rates | The retail margin, on every minute | Call charges up to 72% lower |
The honest caveat, as always: "up to 72%" is measured against standard rates, and your exact saving depends on your call mix. That's why we'd rather re-price a real bill than wave a percentage at you — send us one and you'll see the difference line by line.
Same lines, same phones — different rates underneath
There's no trick to explain away. Your calls travel over the same Openreach network they always have — the same lines and the same engineers the big retailers use. What changes is the agreement your calls are billed under: wholesale rather than retail, with the middleman's margin taken out of every minute. That's why the discount can be this large without anything about how you work changing.
- No engineer's visit, no downtime. Nothing physical is touched. Your lines, phones and numbers stay exactly as they are.
- One bill you can actually read. Itemised and accurate, with mobile calls priced at the rate we quoted — not a rate you discover afterwards.
- Experts on the end of the phone. A team in Poole and Hyde that answers its own calls and can actually fix things — no ticket ping-pong.
- It's one piece of a smaller bill. Mobile rates sit alongside our other business call charges — UK landline calls, and international calls if you ring abroad — all priced the same wholesale way.
Where "from 8p a minute" actually lands
Think about who your business rings in a normal week. A builder chasing suppliers and homeowners. A recruiter working through a list of candidates. A surgery confirming appointments. A sales office doing follow-up calls. In every one of those, the overwhelming majority of numbers dialled are mobiles — so the mobile rate isn't a footnote on the tariff, it's effectively the price of your outbound calling.
Move that calling from a marked-up retail rate to 8p per minute, add per-second billing so short calls stop being rounded into long ones, and the saving repeats on every call, every day, indefinitely. Against standard rates, call charges come out up to 72% lower — and because nothing about your setup changes, there's no cost or disruption to offset against it. The saving is simply the margin you stop paying.
If your team makes genuinely long mobile calls — support lines, account management, anyone who settles in for a chat — a capped call package goes further still: calls to mobiles capped at 20p for up to an hour, so a forty-five-minute call costs the same as a five-minute one. And if you'd rather have a fixed monthly figure than any per-minute rate, inclusive-minutes packages roll your calls into one predictable price.
Pair the calls with wholesale line rental
Call charges are half the bill; the other half is the line itself. Business line rental with us is £13.99 a month — typically a 42% saving, on the same Openreach line you have now — and if you find it cheaper elsewhere, we'll beat the price and add a month free. Put wholesale line rental under wholesale call rates and the saving compounds on every single bill. See the full range of business phone line services — including SIP trunks if you're heading towards internet calling — or start with the line you already have.

Business calls to mobiles FAQs
How much do business calls to UK mobiles cost with UK Wholesale?
From 8p per minute, with one flat rate covering every UK mobile network, and per-second billing after the first minute. There are no different prices for different networks and no exclusions hidden in the small print. Against standard rates, our call charges work out up to 72% lower.
Why are landline-to-mobile calls so expensive on a business bill?
Calls to mobiles cost more to terminate than calls to landlines, and retail tariffs add a healthy mark-up on top, often with rounded-up minutes and different rates per network. Because most business calls now end on a mobile, that marked-up rate effectively prices most of your outbound calling. Wholesale routing removes the retail mark-up while the calls themselves stay exactly the same.
Does the rate really cover every UK mobile network?
Yes. EE, O2, Vodafone, Three and the virtual networks that run on top of them are all charged at the same rate. You never need to know or check which network the number you are dialling belongs to.
Do I need new phones, new lines or an engineer's visit?
No. Your calls are re-routed over our wholesale agreements, which is a billing and routing change, not a physical one. You keep your existing lines, phone numbers and equipment, and there is no downtime while the switch happens.
What is per-second billing and why does it matter?
After the first minute, we bill calls by the second rather than rounding up to the next whole minute. Business calls are often short, so on a tariff with rounded-up minutes you can pay for a substantial amount of time nobody actually spent on the phone. Per-second billing means the bill reflects the calls you genuinely made.
Can I cap the cost of long calls to mobiles?
Yes. Our capped call packages limit the cost of a call to mobiles to 20p for up to an hour, so long calls stop being expensive calls. We also offer inclusive-minutes packages if you would rather pay one fixed monthly price for your calling. If you tell us how your business uses the phone, we will recommend whichever works out cheapest for you, even if that is the simple per-minute rate.
Can I move just my call charges and keep everything else where it is?
Yes. Call charges can be switched on their own, with your line rental staying where it is. That said, most customers pair wholesale calls with our business line rental at 13.99 pounds a month, typically a 42% saving, so both halves of the bill shrink at once.
How do I find out what my business would actually save?
Send us a recent phone bill and we will re-price it at our rates, line by line, so you can see the saving in black and white rather than as a percentage. There is no obligation and no hard sell, and we usually turn it around within one working day.
