Our verdict
O2 Espana suits people in Spain who want a network-run SIM only line, 5G and an eSIM with no commitment attached. Entry sits at €5 on rolling billing, and EU roaming is already included. The trade-off is reach: the plan is sold for ES only.

Pros and cons
Pros
- Rolling billing on rolling with a 1-month plan term, so nothing locks a line in for a long stretch.
- Sim only plans start at €5, under the site median of €9.30 for entry prices.
- EU roaming is included in the plan rather than a pack bought at the border.
- 5G and an eSIM are both there, and the seller type is network, so the network itself provides the line.
- Support runs on phone, email and chat, covering phone, email, chat and a help centre.
Cons
- Service runs in ES only, so the line is no use outside Spain.
- Billing is on rolling terms, and unlike GETESA, which offers prepaid and contract billing, no prepaid or contract option appears here.
- The price rise rule allows a change if included entertainment services change price, with advance notice.
- The reference plan prices climb steeply with data, and yesss! covers contract, rolling and prepaid billing formats that this provider does not.
Who it suits
- People in Spain who already have a handset and need data and voice on a line run by the network itself.
- Travellers who want included roaming included rather than bought as a roaming pack.
- Shoppers who want an eSIM and 5G from a network seller rather than a reseller.
Who should look elsewhere
- Anyone needing a line outside Spain, because the plan is sold for ES only.
- Buyers who want prepaid or contract billing, which Lonestar Cell MTN offers on contract and prepaid.
- Readers who want prepaid and contract billing under the same brand, since yesss! lists contract, rolling and prepaid formats and O2 Espana lists rolling alone.
What it does well
The mobile range is built around SIM only plans, and the network runs them itself. Entry sits at €5, with the reference plan prices stepping up as the data allowance grows, all sold with no commitment attached. Billing runs on rolling terms and the plan term available is 1 month, so a line can be handed back without paying for the rest of a fixed period. The network carries 5G, and an eSIM is available, which matters for anyone travelling or using a handset with no physical SIM tray. Roaming in the EU is included, so moving across the region does not open a separate roaming bill. The seller type is network, so the line comes straight from the network rather than from a reseller, and support runs on phone, email and chat.
Who runs it
O2 Espana is the consumer face of Telefonica in Spain, and the contracting companies behind the brand sit under that parent. The headquarters country is ES, and the plan is sold for use in Spain, so the offer is a national one rather than something wider. Support is handled through phone, email and chat, so a line holder can reach the operator by phone, by email, by chat or through a help centre instead of an outside support desk. The same company sells fixed line broadband on fttp, with a Free HGU router included and a setup fee of €0, so mobile and home can sit with the same operator. Its stated exit terms are No minimum term and no hidden penalties.

Frequently asked questions
How much does a SIM only line cost?+
Plans start at €5, and the reference plan prices climb with the data allowance, from a small bundle to a much larger one. Every entry on the mobile page is SIM only, so no handset is folded into that figure. The larger bundles cost several times the entry rate, so the allowance has to match real usage.
Is there a minimum contract term?+
The plan term available is 1 month and billing runs on rolling terms, so a line can be ended without a fixed term. Rolling billing is the only model listed, and unlike GETESA, which also offers prepaid and contract billing, nothing here forces a set stretch of monthly payments.
Does the plan include roaming?+
Roaming in the EU is included, so travel across the region is part of the plan rather than a separate add-on. Data used abroad still counts against the allowance of the plan you pick, so a heavy roaming month can eat into a smaller bundle. That matters most on the entry plan.
Can I get an eSIM and 5G?+
Both are available. An eSIM is offered, which suits anyone using a handset with no physical SIM tray, and the network supports 5G. Neither needs a separate subscription on top of the plan price, and the eSIM can be set up before a trip rather than on arrival.
Which countries does this plan cover?+
The plan is sold for use in Spain, and the headquarters country is ES. A line bought here is a Spanish line, useful for travel inside the EU with included roaming, but it does not serve as a local number for living abroad.
Who provides the line?+
The provider is the network itself, with a seller type of network, rather than a reseller buying service from someone else. The contracting companies sit under Telefonica in Spain, and the same operator also sells fixed line broadband to the same households.
How do I get help if something goes wrong?+
Support runs through phone, email and chat, so you can pick phone, email, chat or a help centre. Since the same operator also sells fixed line on fttp, with a Free HGU router included included, home and mobile questions can go to the same desk rather than two providers.
Can the price rise later?+
The price rise rule allows a change if included entertainment services change price, with advance notice. A change on the bundle side can therefore move the monthly figure, so the price is worth checking at renewal even though the plan itself carries no fixed term.
