Network notes

Vodafone

A long-established network on a mast estate entirely its own, halfway through merging with a former rival — which makes testing your own postcode more important here than anywhere else.

Read this first

How we are placed. thurlowvance is an independent information service for mobile customers in the United Kingdom. We are not a mobile network. We have no affiliation with, endorsement from, appointment by or connection to Three, EE, O2, Vodafone, Sky Mobile, Tesco Mobile or any other provider, and no commercial arrangement with any of them. We do not sell, supply, arrange or broker SIM cards, contracts, handsets or services of any kind, and we take no commission from anybody. Everything here is general information; a provider's own current terms always take precedence.
Note 01

The company, and who owns it

Vodafone has run its own national infrastructure for as long as Britain has had a mobile market. Since June 2025 it has formed half of VodafoneThree, the largest operator in the country by customer numbers.

The point that matters most when comparing networks is easy to overlook: this is a separate mast estate from Three's, O2's and EE's. A coverage result obtained on any other network tells you nothing about this one.

DetailWhere it stands
AgeAmong the longest-standing in the market
OwnerVodafoneThree
Merger completedJune 2025
Cheaper brands on these mastsVOXI, run by Vodafone itself, and Lebara
EstateIts own, distinct from the other three
Practical effectPostcode results move more than usual while estates merge
Worth knowingAs on the merger partner, callers demanding an urgent plan “migration” are running a scam. No such process exists on either brand.
A coverage result from another network tells you nothing here. This is a separate estate.
Note 02

Coverage — a separate estate, and a moving one

A broad national footprint with serious money going into consolidation. Because two estates are being combined, an address that failed a year ago may pass now — and occasionally the reverse.

That makes an annual re-check worth more on this network than any other, and a one-month test through VOXI or Lebara the sensible way in.

  1. Run this network's own checker and Ofcom's, ignoring anything learned on another network.
  2. Buy a rolling month on VOXI or Lebara — identical masts, small money.
  3. Live on it through an ordinary week, indoors as well as out.
  4. Run the whole check again in twelve months.
Note 03

SIM plans

Rolling and fixed terms, unlimited available, multi-line reductions for households. Pick the length by how settled your circumstances are.

Two tenant brands on these masts are worth knowing about before you buy the parent brand:

BrandWhat it is built around
VOXILeaves selected social and video apps outside the allowance, which can hugely increase usable data. The exempt list changes — confirm before buying
LebaraGenerous international minutes on cheap rolling plans. Introductory rates commonly step up after an initial period
Note 04

Phone plans

Combined bundles across twenty-four to thirty-six months, with a credit check on the device element. The monthly figure does not fall when the term ends.

One calculation settles every offer: upfront plus monthly times months, against the same handset bought outright plus the cheapest suitable SIM.

Worth knowingDiary the contract end date on the day you sign, with a reminder a month before. Nothing happens automatically and nobody is required to tell you.
Note 05

Prepaid

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

SituationWhy prepaid fits
A spare or glovebox phoneNo monthly cost and nothing to cancel
A child's first phoneThe spending ceiling is the whole point
Somebody new to the UKNo credit history required
Testing coverageOne month answers what no map can
Worth knowingMost prepaid services need the line used occasionally, or the credit and sometimes the number lapse. A phone kept only for emergencies is exactly where that hurts. Read the actual condition and set a reminder.
Note 06

eSIM

eSIMs are issued here within minutes on recent handsets, through the official app or website.

  • Issuing, transferring and reissuing an eSIM is free on every UK network, including after a lost handset.
  • Keeping your number uses the ordinary free switching code — digital and plastic SIMs are treated identically.
  • Request one only inside the official app or website, never through a link somebody sent you.
  • For travel, add a cheap local data profile and keep the UK line for calls and texts.
Worth knowingThere is no eSIM activation fee, transfer service or migration charge anywhere in UK mobile. A demand for payment is itself the proof of fraud. Forward the message to 7726, free.
Note 07

Home broadband

Broadband here runs over Openreach fixed lines, decided by the line to your property rather than your nearest mast. Check availability separately from mobile coverage; the two answers are unrelated.

Bundle discounts are real, but choose the mobile network on coverage first — a broadband saving is a poor reason to accept weak signal at home.

Note 08

Roaming abroad

Roaming here varies by plan generation more than by anything else, which means two people on the same network can be under completely different rules depending on when they signed. Only the roaming screen inside your own app settles it.

  1. Read your roaming screen before booking, and write the ceiling down as a number.
  2. Check the free spend cap is switched on.
  3. Turn off automatic backups and app updates over mobile data.
  4. On any trip past a few days, buy a cheap local data eSIM and keep the UK line for calls.
Worth knowingFerries, cruise ships and some aircraft bill through satellite systems that sit outside ordinary roaming and outside your spend cap. That is where the very largest bills originate. Switch mobile data off before you board.
Note 09

Data, and what 'unlimited' leaves out

ConditionWhat it actually does
Tethering capLimits sharing data with a laptop on some plan generations
Traffic managementQueues extreme outliers at saturated masts; ordinary heavy use never notices
Fair use abroadEnds the unlimited part at a published figure, then charges per gigabyte

Two free adjustments often remove the need for a bigger tier: drop video quality one step inside the streaming app, and push backups, photo sync and app updates onto home Wi-Fi.

Note 10

Monthly and yearly costs

FigureWhat it really is
Introductory priceReal, time-limited, and useless for comparing networks
Standard priceWhat applies once the discount ends — this is the price
Out-of-contract priceThe same again, on a handset you already own
Whole-term costUpfront plus monthly times months — the only fair comparison
Yearly costMonthly times twelve; ask for it, because it is rarely offered

The free spend cap takes about a minute in the app and prevents charges beyond your allowance entirely. Almost nobody switches it on.

Note 11

Price rises, and how to bring a bill down

ReasonBehind it
A mid-term increaseSince January 2025 it must be stated in pounds and pence before you sign
An introductory discount endingThe commonest cause; the duration was stated at purchase
Charges beyond the allowanceOnly possible where no spend cap was set
A minimum term endingNot a rise: a fall that failed to happen
An add-on renewingSingle-period purchases occasionally repeat
MoveEffect
Switch to SIM-only once the term endsStrips out the handset payment
Cut the allowanceWhere three months of usage shows the tier is oversized
Buy a one-off add-on instead of upgradingCovers a heavy month without repricing the year
Negotiate with rival quotes in handTake a switching code first
LeaveThe exit position is itemised before you commit
Note 12

The app, and account security

One application covers allowances, billing, spend caps, add-ons, roaming settings, eSIM requests and written support. Use the written route for anything you may need to evidence later: a telephone call leaves no file, and a file is what somebody reviews.

  • Install it on day one and set the free spend cap while you are there.
  • Turn on Wi-Fi Calling so walls stop mattering, and 4G Calling so voice works at all.
  • Give the account a password used nowhere else, and switch on every extra protection.
  • Install only from the official app store, never from a link in a message.
Worth knowingGenuine offers appear inside the app. If a caller's deal is not there, the call is not real — whatever the caller ID says. No genuine employee of any network ever needs a one-time code read aloud.
Note 13

Faults and glitches, and why they happen

What you seeUsual causeCure
An older handset dropping calls3G has been switched off nationallyTurn on 4G Calling; if the phone cannot, it has reached its end
One room always poorBuilding materials blocking radioTurn on Wi-Fi Calling
Full bars but nothing loadsToo many handsets on one mastNothing on the phone helps — it is capacity, not coverage
A whole street out for hoursMast work or a local faultCheck the status page with your postcode

If a problem keeps returning, log dates, times and what failed for a fortnight, then complain in writing with the log attached and ask what goodwill applies to the recorded period.

Note 14

PAC codes, joining and leaving

Joining. Check coverage before price. Buy the new plan, text your old network for the code, hand it over, and leave the old SIM in until the number moves — usually one working day, with no gap.

Leaving. Switching runs entirely on text messages. No conversation is required and none can be insisted upon.

TextToResult
PAC65075Your number moves across. Free, back in minutes, valid thirty days
STAC75075The account closes and the number is given up
The replyItemises any early-exit charge and handset balance before you commit

Your network cannot refuse the code, sit on it, attach conditions, or make a retentions conversation a precondition of leaving. If a complaint stalls, write it down, keep the reference, and escalate free to the Communications Ombudsman at eight weeks or on a final response.

Note 15

Who it suits

Who it suits

A good fit for

  • Households whose own postcode tests well on this estate
  • People calling abroad regularly, via Lebara
  • Heavy social media and video users, via VOXI
  • Anyone willing to re-check coverage each year
  • People wanting a big-four network with cheaper options on the same masts

A poor fit for

  • Anyone assuming a coverage result from another network applies
  • People who dislike checking their own roaming terms
  • Anyone who will not diary a contract end date
  • People wanting settled, unchanging coverage right now
  • Prepaid users, who usually do better on VOXI or Lebara

In a sentence: a solid national network in the middle of the biggest change in its history — worth testing on your own postcode, and worth testing again next year.
