You came home to a huge roaming bill: what to do now
Ask for the itemised bill, find the days, countries and networks behind the charge, and complain to your operator first, keeping the reference number. If you are in Spain and the operator does not answer within a month, or the answer does not satisfy you, you then have three months to take it to the government's telecom user office.
See data plansFirst, understand where the charge came from
Before you argue about the amount, get the itemised bill from your operator's app or customer area. For each roaming charge you want four things: the date, the country, the network and the type of use, whether data, calls or texts. That is usually enough to tell what happened.
The most common causes are recognisable. A charge on a day you were on a ferry, a cruise or a plane often comes from the vessel's own satellite network. Charges on a day you were near a border can come from the phone connecting to the stronger signal from the other side. And charges spread over many days usually point to apps syncing in the background on your home line. We cover how each of these happens in how to avoid roaming charges outside the EU.

Will it work on my phone?
On iPhone: Settings → General → About, and scroll to EID. If there is an EID, your phone takes eSIMs. Every iPhone from the XS (2018) onwards does.
On Android: Settings → About phone → Status, and look for EID. If there is an EID, your phone takes eSIMs. Most Galaxy S20, Pixel 3 and later do.
It also has to be carrier-unlocked. If you bought it outright or your contract is over, it almost certainly is.

What EU rules required your operator to do
If your line is from an EU country, the rules give you protection you can point to. The EU's Your Europe portal explains that your provider must automatically apply a cut-off when your roaming data use reaches an extra 50 euros, or any other limit you chose, unless you told them you wanted to keep going. The operator must also notify you when you reach that limit, and that notice has to include the price of each additional unit.
Two things weaken that protection. If you once asked to remove the limit or accepted to continue, the cut-off no longer applied. And outside the EU, or on the satellite networks of ships and planes, BEREC, the body of European telecom regulators, says the cut-off only applies when the visited network allows usage to be monitored in real time; on those satellite networks prices are not capped either. If none of that applies to you and you never got the notice or the cut-off, say so explicitly in your complaint.
Regulators do act on this
These are not theoretical rules. In Ireland, the telecom regulator investigated an operator whose customers had not received the required notice when they reached the default roaming limit, or had received one without the price per extra unit. The operator agreed to refund around 14,000 affected customers.
A single complaint will not trigger an investigation like that, but it shows what the regulator considers a breach. If your bill shows data charges that kept running far past the limit without any message from your operator, mention the date you think the limit was reached and ask the operator to show when and how it notified you.
Complain to the operator first, and get a reference
In Spain, the official telecom user office is clear about the order: a complaint has to be made first to the operator that provides the service. The operator is obliged to give you a reference number, which proves when you complained. If you complain by phone, you can also ask for a document that records the complaint and its content.
Write the complaint as if someone else will read it later, because they may. Say which charges you dispute, on which dates, and why: no notice received, a cut-off not applied, a network you never chose. Attach the itemised bill and any texts from the operator. Keep everything, including screenshots of your phone's data settings during the trip if you have them.
If the operator does not fix it
If after one month you have no answer, or the answer does not satisfy you, in Spain you can go to the Oficina de Atención al Usuario de Telecomunicaciones. The deadline is three months from the operator's answer, or from the end of that month if it never answered. You can file online with a digital certificate or Cl@ve, or on paper, and the office has six months to resolve. If you prefer, consumer arbitration boards are another route when the operator accepts them.
Outside Spain, the EU's advice is the same in substance: use your operator's complaint procedure first, and if you are not satisfied, contact your national telecom regulator.
So the next trip is boring
The quiet fix is to stop your home line from using data abroad at all. Switch off data roaming on that line, which still lets calls and texts arrive, and use a separate data plan for the internet; we show the steps in how to turn off roaming on your home line.
A data eSIM such as Snoozim's works that way: it handles the data, your number stays on your usual SIM, and every purchase comes with a VAT invoice, so you know the cost before the trip rather than after it.
Does the 50 euro roaming limit apply outside the EU?
For lines from EU countries it can, but only when the visited network allows real-time monitoring of usage. If you chose another limit or asked to continue, the default no longer applies.
How long do I have to complain to my operator?
The Spanish user office does not set that deadline on its complaints page, so complain as soon as you see the charge and keep the reference number.
When can I go to the Spanish telecom user office?
When the operator has not answered within a month or its answer does not satisfy you. From then you have three months to file.
I am not in Spain. Who do I complain to?
Your operator first, then your national telecom regulator if the answer does not satisfy you.
