As of 13 August 2026, AI can dispute a roaming charge.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

   How to actually do it

   1. Open your mobile provider's bill and complaint page, then gather the roaming charge, billing period, country or countries, dates, plan terms, roaming allowance and any text messages or emails about the charge.
   2. Remove passwords, payment-card details, account security answers and other unnecessary personal data before pasting the documents into an AI chat.
   3. Paste the supplied prompt followed by the redacted bill, provider correspondence, plan terms and your own chronological account of what happened.
   4. Ask the AI to keep a separate list of facts, missing evidence and claims that need checking, then fill each square-bracketed placeholder from your records rather than guessing.
   5. Compare every amount, date, country, quoted term and description in the draft with the bill and provider messages, and check any rule or complaint-route statement against the provider's current official page or GOV.UK.
   6. Send the corrected complaint through the provider's official complaint channel, attach the relevant evidence, save a copy and record the submission date and any reference number.
   7. If the provider rejects the complaint or the amount is significant, follow its stated escalation or alternative-dispute process and consider a solicitor for a serious legal case.

   Prompt

   Help me prepare a factual complaint about a UK mobile roaming charge. Use only the information I provide and do not invent dates, amounts, contract terms, regulations or conversations. First list the facts you have extracted, then list any missing information or contradictions. Next, identify which claims need checking against my bill, contract, provider messages or current official guidance. Then draft a concise complaint to my mobile provider requesting a review and, if justified by the evidence, a refund or correction. Include the charge amount, dates, country or countries involved, relevant plan or roaming allowance, what I was told, the remedy requested and a request for a written explanation. Do not present legal conclusions as facts. Do not include passwords, full payment-card details, account security answers or unnecessary personal data. Keep placeholders in square brackets where evidence is missing. Here are my details and documents: [paste the bill, provider correspondence, plan terms and my account of what happened].
