Is fibre + mobile or fibre-only cheaper?

In today’s telecoms market, it’s common to find convergent offers that combine fibre optic for the home with mobile phone lines, as opposed to fibre-only tariffs. Choosing between signing up for a bundled package (fibre + mobile) or fibre alone can make a big difference to the price and to the services included. We’re going to analyse which option works out better value in different scenarios and compare the prices and features of current plans from various companies. The aim is to help you work out whether a combined internet and mobile package or a standalone fibre-only tariff suits you better, taking into account speeds, mobile data, prices and contract conditions.

Bundled package vs fibre-only: which is better value?

Generally speaking, signing up for fibre optic alone tends to have a lower monthly cost than a bundled package, since you’re not paying for additional services. In fact, in Spain you can find fibre-only tariffs from around €17–20 a month, while full convergent packages (which include fibre + mobile and sometimes TV) easily exceed €50 a month. This is because bundled tariffs add the cost of the mobile line (and other extras such as television), pushing the price up. The advantage of a fibre-only connection is that it lets you keep costs to a minimum and gives you the flexibility to choose other services separately (for example, taking out a low-cost mobile line with a different operator). What’s more, many internet-only tariffs don’t require long minimum contract terms, unlike packages, which typically involve 12 or 24 months of commitment.

That said, this doesn’t mean it’s always better to sign up separately. In certain cases, operators offer discounts for combining services, meaning that adding a mobile line to your fibre increases the total cost very little. In other words, if you need both home internet and a mobile phone anyway, a unified package can work out cheaper than taking out each service separately. For example, some low-cost companies let you add a mobile line for only €3–5 more a month compared with the fibre-only tariff, which represents a big saving compared with taking out a standalone mobile tariff at the standard price. In terms of convenience, convergent packages also simplify billing (a single bill and a single provider) and make support easier to manage.

Your choice should be based on your needs: if you only need an internet connection at home (for example, for working from home, studying or entertainment) and you’ve already sorted out your mobile (or you don’t use it much), the cheapest option will be fibre only. On the other hand, if you need both, it’s worth looking at integrated offers, since many represent excellent value for money when you make use of all the services included. Remember also to consider factors such as coverage (not every company has fibre available in every area) and the minimum contract term. Some convergent operators don’t impose a minimum term, while others do. For example, O2 and Pepephone offer packages with no minimum term, while Digi, Lowi, Simyo, Yoigo and MásMóvil usually require around 3 months of commitment, and other operators up to 12 months. This aspect can affect how freely you can switch in the future without penalties.

Comparison of prices and features from different companies

To better understand the differences in cost, let’s compare some current fibre-only tariffs against combined fibre + mobile tariffs from various companies in Spain. We’ll indicate the fibre speed (always symmetrical), the mobile data included, the monthly price and relevant conditions such as minimum contract term or promotions.

Examples of fibre optic only tariffs

Digi (fibre only) – 300 Mbps for €10 a month. It’s one of the cheapest offers on the market, thanks to the fact that Digi uses its own network in certain areas. Conditions: requires Digi’s own coverage (around 11 million homes) and involves a 3-month minimum term. It doesn’t include a landline (optional) and the IP allocation is via CGNAT (you can pay €1 extra for a public IP). If you want a higher speed, Digi offers 1 Gbps for €20 and up to 10 Gbps for €25 in areas with Pro-Digi technology, again at permanent prices.
Lowi (fibre only) – 600 Mbps for €20 a month in areas with Lowi’s own coverage. Lowi, Vodafone’s sub-brand, has joined the low-price war: it offers 600 Mb fibre for €20/month provided you’re on its direct network (“Lowi Fit”). Conditions: 12-month minimum term and a €30 connection/installation fee. It doesn’t include a traditional landline. Outside Lowi Fit areas (using third-party indirect networks) the price goes up by around €5 (coming to about €25).
Finetwork (fibre only) – 600 Mbps for €20.90 a month. Finetwork, a low-cost operator, offers this permanent tariff with a 12-month minimum term and no landline. Installation may carry a charge (in 2024 they charged up to €75). It also has 1 Gbps for €22.90 a month. These are final “forever” prices. Finetwork uses Vodafone/Orange coverage (around 20 million homes).
Movistar (fibre only) – 300 Mbps for €19.90 a month (12-month promotion) and then €38/month. The market-leading operator offers its symmetrical fibre at that promotional price for the first year; from the second year the standard cost rises to €38. Conditions: no minimum term (you can cancel at any time). It includes a landline with unlimited calls to landlines and 50 minutes to mobiles, plus a Smart WiFi 6 router included. It’s a quality option but more expensive once the promotion ends, as is typical of the big operators.
O2 (fibre only) – 300 Mbps for €27 a month. O2, Telefónica’s low-cost brand, offers this fibre tariff (300 Mb symmetrical) which includes a landline with calls to national landlines and mobiles. Conditions: no minimum term and a final price (it isn’t a temporary promotion). O2 also has 1 Gbps fibre for €31 a month. These tariffs compete directly with those of cheaper operators, but backed by Movistar’s network. They’re ideal if you only want internet at home without extras, while keeping Telefónica’s quality of service.
Yoigo (fibre only) – 500 Mbps for €19.90 a month (12-month promotion) and then €32 a month. Yoigo (MásMóvil Group) sometimes launches aggressive promotions on standalone fibre. On this plan, you pay €19.90 during the first year; after that period, the price is set at €32. Conditions: 12-month minimum term (exactly the promotional period). It includes a landline with unlimited calls to other landlines and 60 minutes to mobiles. Once the offer ends, it’s worth reassessing, since €32 is high compared with other alternatives if you’re not interested in their mobile packs.

Examples of combined Fibre + Mobile tariffs

Digi (fibre + mobile) – 300 Mbps + 30 GB for €15 a month. It includes Digi fibre optic (using Movistar coverage in most areas) and a mobile line with 15 GB of rollover data. Conditions: 3-month minimum term. The 300 Mb fibre can be upgraded to 1 Gbps for +€5.
Finetwork (fibre + mobile) – 1 Gbps + 150 GB for €28.90 a month. It’s Finetwork’s most powerful convergent tariff, recently reduced. For that price you get fast 1 Gb fibre and a mobile line with 150 GB and unlimited calls. Conditions: 12-month minimum term; no landline included. What stands out is how tight the price is: the difference compared with taking Finetwork’s fibre alone (€20.90) is barely €8, which shows the savings that packages bring.
Lowi (fibre + mobile) – 300 Mbps + 35 GB for €25 a month. Lowi combines its 300 Mb fibre with a mobile line of 35 GB rollover data for that fixed price. It also has variants with more data: e.g. 70 GB for €33 or 150 GB for €35. Conditions: 12-month minimum term if you’re under “Lowi Fit” coverage (Vodafone’s own network). No landline included (Lowi doesn’t offer a landline in its packages).
O2 (Telefónica) – 300 Mbps + 30 GB for €30 a month, 600 Mbps + 50 GB for €35, or 1 Gbps + 120 GB for €38. These are straightforward Movistar O2 tariffs with no small print: they include symmetrical fibre and a mobile line with 5G on the Movistar network, plus a landline included with unlimited calls to landlines and mobiles. Conditions: no minimum term (0 months). O2 doesn’t apply temporary promotions; these are stable final prices. For €50 they offer a higher package with more data and optional Movistar+ TV, but the basic plans cover most needs. O2’s advantage is combining Movistar’s quality of service with prices close to those of low-cost MVNOs.
Pepephone (MásMóvil Group) – 300 Mbps + 20 GB for €31.90 a month. Pepephone is known for its no-tricks philosophy: this tariff includes fast 300 Mb fibre and a mobile with 20 GB rollover data (unlimited calls) for €31.90. It also offers 600 Mb + 49 GB for €38.90 and 1 Gbps + 149 GB for €48.90. Conditions: no minimum term and unused gigabytes roll over to the following month. It doesn’t throw in extras, but it doesn’t demand anything either (nor does it raise prices after a year).
MásMóvil (fibre + mobile) – 300 Mbps + 30 GB for €29.90; 500 Mbps + 50 GB for €34.90, among other options. The MásMóvil Group (which takes in Yoigo, MásMóvil, Pepephone, etc.) positions the MásMóvil brand with competitive packages starting at €30. Its entry-level 300 Mb offer with 30 GB competes with Lowi and O2.

So which is cheaper: fibre + mobile, or fibre only?

The answer depends on your circumstances and your usage. If you only need a fixed connection at home and don’t want to pay more than you have to, standalone fibre-only tariffs will be cheaper on your monthly bill than any bundled package. For somewhere between €15 and €30 a month you can have high-speed fibre optic with no add-ons, thanks to competition from MVNOs and sub-brands. This is ideal for people who already have a very cheap mobile tariff (or a company line, for example) and don’t need another, or for second homes where all that matters is having internet.

If, on the other hand, you’re going to use both home internet and a mobile line, it’s usually better value and more practical to bring both services together with the same operator. Today’s convergent packages offer clear advantages: for a small difference in price you get mobile data and unlimited calls, and you may even save compared with signing up separately. We’ve seen cases where adding a mobile line to your fibre increases the cost very little (e.g. +€3 with O2 or Finetwork for 30 GB), taking advantage of economies of scale. What’s more, a single provider simplifies managing payments and support.

When does each option make sense? As a final guide:

Choose fibre only if your priority is maximum savings at home, you don’t need a new mobile line (or prefer to keep it separate) and you value the freedom to switch with no strings attached.
Go for fibre + mobile if you want a complete and convenient service. In particular, families and heavy smartphone users tend to benefit from convergent tariffs: a single contract provides home internet and mobile communication with plenty of data for everyone.

If you’re after the absolute lowest price and flexibility, check the fibre-only offers available at your address and combine them with a cheap mobile tariff of your own choosing. If you’re after convenience and an all-in-one solution, combined fibre + mobile offers are probably your best bet. We recommend pricing up both scenarios — adding up the costs separately versus in a package — and considering the additional services included. That way you’ll be able to make an informed decision and tailor your telecoms contract to what you really need, at the lowest possible cost without sacrificing connection quality.
