Vodafone on two plants
The red advert is one shop. The street may be Openreach or CityFibre. The hub will not confess until you ask.
12 min read · Retailers
Vodafone would like you to think in red. Streets think in ducts. In a CityFibre town the same advert can be a different last mile from the village ten minutes away, where the only full fibre is Openreach. Both can be perfectly good. They are not interchangeable on a Friday night when you have ordered the wrong one and an engineer is booked for the plant you do not have.
Ask the plant by name
Before you order, the comparison should say Openreach or CityFibre (or cable, or an alt-net). If a Vodafone journey hides the name, that is a design choice. Make them say it in the confirmation.
The hub firmware and the app will not always tell you later. Keep the PDF.
Switching consequences
Retailer-to-retailer on the same plant is a cease and a new authentication. Plant-to-plant is a new drop, a new ONT, maybe a visit, maybe a week of two boxes.
People leave Vodafone for ‘anyone else’ and accidentally leave CityFibre for a slower Openreach FTTC because they chased a brand. Name the plant you want to keep.
Mobile gravity
The household with four Vodafone SIMs will be shown a line discount that makes the arithmetic look unique. Recalculate the SIMs at public prices. Sometimes the bundle still wins. Sometimes it is a golden handcuff on a mediocre drop.
A 5G backup SIM is a useful extra. It is not the same product as the FTTP you were comparing.
| You are on | Leaving for another retailer on same plant | Leaving for the other plant |
|---|---|---|
| Openreach | Normal OTS, ONT stays | New drop / new ONT |
| CityFibre | Normal OTS among CF retailers | Only if the other plant is live |
Red is a shop window. Purple or grey is a duct. Shop in the duct.
Vodafone is a retailer with a flexible wholesale shopping bag. Look in the bag. Then decide whether you like the shop.
Questions
- How do I know which plant I’m on?
- The order confirmation, the engineer notes, or an honest address check. ‘Vodafone full fibre’ is not an answer.
- Can I switch from Vodafone CityFibre to BT?
- BT will be on Openreach at that address (typically). If Openreach FTTP is also live, you can switch plant. If not, you are leaving fibre for something else.
- Is Vodafone cheaper on CityFibre?
- Sometimes the CityFibre product is the one they push. Compare the tariff in front of you, not a national average.
- Will my mobile stay discounted if I leave the line?
- Often the discount dies. Price the mobile as it will be, not as it is while the line subsidises it.
- Do I get a new ONT if I stay with Vodafone but the town builds a second plant?
- Only if you order the other plant. They will not silently migrate you between trenches because a poster changed.

CityFibre is not a retailer
Several logos, one trench. If the street is CityFibre, you are choosing a retailer on someone else’s fibre — and that is a different job from choosing Openreach.

Openreach is a wholesale machine
The majority trench is not a retailer. It is a factory that sells access to retailers. Your bill is one of those retailers.

Bundling mobile with the line
A £6 line discount that requires four SIMs is a household gravity well. Recalculate the SIMs. Then decide if the well is a well or a trap.

TOOB on CityFibre
A cheap shop on a purple spine. Not a network, not a national overlay, not month-one as a personality.
