Our position in one line

An established national operator now inside the country's largest ownership group, running its own separate estate — and the one whose coverage map is moving fastest as two networks merge.

§1Background

Vodafone is among the longest-established operators in the country and has run its own national infrastructure throughout. Since June 2025 it has formed half of VodafoneThree, the largest operator by customer numbers.

Both brands continue to sell separately while the estates are combined under a large capital programme.

Detail	Position
Ownership	VodafoneThree, from June 2025
Capacity sold to	VOXI, run by Vodafone, and Lebara
Estate	Distinct from Three's, O2's and EE's — check it separately
Consolidation	Coverage at a given postcode is changing more than in ordinary years

Common pitfallAs on Three, callers demanding an urgent plan “migration” on merger grounds are committing fraud. No such process exists on either brand.

Uncertain what the merger means for you?

Telephone the advisory and we will talk it through. There is nothing to buy at any point.

§2What is offered

Service	What you are actually buying
SIM plans	Rolling monthly, fixed terms and unlimited tiers
Phone contracts	Handset and airtime combined over 24–36 months
Pay as you go	Available; VOXI and Lebara usually cheaper for regular use
eSIM	Issued in minutes on recent handsets, free through official channels
Home broadband	Fixed-line services over Openreach
Roaming	Varies by plan generation; your app's roaming screen is the authority

Because this is a separate estate, a coverage result obtained on any other network tells you nothing about it. The checkers must be run again.

§3SIM plans

Term	Who it suits
One month, rolling	Anyone whose coverage or address is unproven
Twelve or twenty-four months	Settled households, with the end date diarised
Unlimited	Heavy data users, subject to the qualifications below

Where unlimited is qualified. Unmetered on the handset at home; bent in three places:

Tethering capped on some plan generations despite the headline.
Brief queueing at extremely saturated masts for outliers only.
A fair-use ceiling everywhere abroad, then per-gigabyte charging.

Sizing the allowance. Your network app records real consumption. Three months of it, plus modest headroom, is the figure to buy — the gap between estimate and reality is commonly around double.

§4Phone contracts

The standard combined bundle, with a credit check on the device element. The end-of-term position is the same as elsewhere: the monthly figure does not fall by itself.

Test any proposal with one sum — upfront plus monthly times months, against the handset outright plus the cheapest suitable SIM.

§5Pay as you go

Credit-based, with no contract and no credit check. For regular use, VOXI and Lebara on the identical masts are generally better value.

§6Bills, month to month

Figure	Why it matters
Post-discount price	The real price; introductory rates have a stated duration
Out-of-contract figure	Continues unchanged until you act
Spend cap	Free, and the main defence against charges beyond the allowance

§7Price changes

Mid-contract increases must be stated in pounds and pence before signature since January 2025. A bill comes down through SIM-only at term end, a right-sized allowance, add-ons instead of upgrades, competing quotes, or departure.

§8Verify before you commit

Run Vodafone's own checker and Ofcom's — independently of any result from another network.
Audition for a rolling month through VOXI or Lebara.
Re-check coverage annually while the two estates are being merged.
Read your plan's roaming screen before booking any trip.

§9Common pitfalls

Common pitfallAssuming a coverage result from Three, O2 or EE applies here. It does not — this is a different estate.

Common pitfallActing on a telephone call about merger “migration”. No such process exists.

Common pitfallBuying on what the combined network may become rather than what you can verify today.

§10Joining

Coverage-check on Vodafone's own checker and Ofcom's.

Audition a rolling month on VOXI or Lebara.

Buy the plan and bring your number in with the free code.

First day: Wi-Fi Calling on, 4G Calling on, spend cap set, end date diarised.

§11Leaving

Switching runs on two text messages and requires no conversation.

Code	What it does
Text PAC to 65075	Carries your number across. Free, back within minutes, valid thirty days.
Text STAC to 75075	Closes the account without carrying the number.
The reply	Itemises any term charge and device balance before you commit.

Your provider may not refuse the code, delay it, attach conditions, or make a retention call a precondition of leaving.

Buy the new plan first.

Text for the code and read the itemised reply.

Hand it over and keep the old SIM in until the number lands.

Diary a check that the final bill closes at zero.

If a complaint stalls: write, keep the reference, and refer it free to the Communications Ombudsman at eight weeks or on a final response.
