V3 SIM Launched: Now Supports Roaming in 170+ Countries πŸŽ‰

Work Anywhere Without Losing the Call

Client calls from a car park, a site visit, a train, a rented cottage with one bar. When you work for yourself, a dropped connection isn’t an inconvenience β€” it’s the meeting you were being paid for. FlexiFone runs across EE, O2, Vodafone and Three on one SIM, picking whichever has signal wherever you’ve ended up, and tethering is unrestricted so the laptop comes too.

FlexiFone Annual Plan — 30GB a month
£155 /year
£12.92 a month · 360GB across the year
  • All four UK networks, switching automatically
  • Roam like home in 170+ countries (25GB a month abroad)
  • Unrestricted tethering — no hotspot ban, no app allow-list
  • eSIM free, or a triple-cut physical SIM for £3.50

Two hours of video calls uses about two gigabytes. 30GB covers a few days a week out of the house — client sites, trains, a coworking desk — without watching the meter. And because it moves between all four networks, a café with poor coverage on one of them isn't a wasted afternoon.

Only out of the house occasionally? 10GB is £65 a year. No fixed broadband at all? 50GB is £225 — the first tier that genuinely replaces a line.

Why Freelancers End Up on a Multi-Network SIM

Working for yourself means working wherever the work is, and no single network covers everywhere you’ll be asked to be.

01

Four networks, chosen for you

You don’t get to pick your co-working space, your client’s office or your in-laws’ spare room. The SIM connects to whichever of the four has usable signal there, without you touching settings.

02

Unrestricted tethering, every plan

Hotspot the laptop for as long as you need. No app allow-list, no hotspot ban, no throttle when you share β€” the restrictions budget SIMs quietly apply are the ones that break a working day.

03

Cheaper than one lost meeting

Β£12.92 a month sits alongside your existing contract as an eSIM. When your main network fails at the moment of a call, the call still happens.

04

It works abroad too

Roam like home in 170+ countries including the EU and EEA, subject to fair use. A workation or a client trip doesn’t need a second plan.

Where This Actually Saves the Day

Four situations, and what actually happens in each.

Scenario The problem What FlexiFone does
A client call from the car You've arrived early, the call is in five minutes, and your network has one bar here. Connects on whichever of the four networks covers that car park, so the call goes ahead.
A site visit or client's office Thick walls and a guest Wi‑Fi network you can't get onto. Tether the laptop from your own connection instead of asking anyone for a password.
Working from somewhere rural A cottage or a family house where your usual network simply doesn't reach. Coverage gaps rarely overlap — where one operator has nothing, another usually has bars.
A deadline during an outage Your home line is down and the work is due today. Hotspot and carry on. Our backup internet page has the full failover setup.

Frequently asked questions

Everything You Need to Know About Working Away From a Desk

How much data do video calls use?

Roughly 0.5–1.5GB an hour, depending on the platform and whether cameras are on. Six hours of calls a month is somewhere around 3–9GB β€” which is why the 10GB plan is the recommendation here and 5GB usually isn’t.

Is tethering really unrestricted?

Yes, on every plan, at home and abroad. It’s worth checking this on any SIM you buy: several budget providers either ban tethering, cap it separately from your main allowance, or slow it once you pass a threshold they don’t advertise.

Will it replace my broadband?

For a working day, often yes. As a permanent replacement, treat it as a serious question rather than a yes β€” you’d want to check typical speeds at your address and be realistic about how much data you get through in a month. Most people use it as a second connection, not a substitute.

Can I claim it as a business expense?

Usually, where it’s used for work β€” but we’re not accountants and the rules depend on how you’re set up. Ask yours. We can provide a VAT invoice for the plan either way.

Can I run it alongside my existing contract?

Yes, and that’s how most freelancers use it. Install it as an eSIM on a dual-SIM phone, keep your number on your main line, and set FlexiFone as the line your data uses. Any iPhone XS or newer, Galaxy S20 or newer, or Pixel 3 or newer will do it.
