O2 customer service: phone number and in-person help
If you are looking for the O2 phone number, here it is. And if you would rather have a real person sort it out face to face, come to one of our three official stores in Tarragona, Reus and El Vendrell.
What we sort out in store
- Understanding or disputing a bill: we go through it with you and, if there is an error, we support you with the claim.
- Changing plan or adding lines: we process it with you, with no new lock-in.
- Fibre or mobile faults: we help you check the router and coverage, open the ticket with you and follow up until it is fixed.
- SIM replacement and eSIM: we request it with you in store with your ID.
- Porting, cancellations and lock-ins: we tell you exactly what is left and what suits you, and process it with you.
- The TV in your plan: we explain how to activate Movistar Plus+, Netflix and Disney+ and help if they do not show up.

Frequently asked questions
What is the O2 customer service phone number?
1551 from an O2 line, free and with 24-hour fault support. If you are a customer of our stores, call or message us first: we help you and, if it needs escalating, we stay with you.
How do I view or pay an O2 bill?
In the Mi O2 app or at o2online.es with your login. If you do not understand it or think there is an error, bring it to the store and we go through it line by line.
What do I do if I have no internet?
Restart the router for 30 seconds. If it still does not connect, message us on WhatsApp with a photo of the router lights: we tell you if it is a fault, open the ticket with you and stay with you until it works again.
How do I change plan or add a line?
In store, with no new lock-in. Also on WhatsApp if you are already our customer.
How do I get a replacement SIM or an eSIM?
Come to the store with your ID and we request it with you; we explain how to activate it when you have it.
How do I cancel O2?
By calling 1551 or in store. Before you leave, let us look at your plan: there is often a better one for what you use.
