Before making the call
The number on this website is for popost’s independent guidance service. It is not a network customer-service number. There is no charge for our guidance; your telephone provider’s normal charges may apply to the call. No particular availability or opening hours are promised.
What to bring to the conversation
Identify the page or term that is unclear and describe the issue in general terms. You do not need to provide your account password, bank details, one-time codes, PAC, identity documents or eSIM activation credentials. Keep confidential account information for your provider’s authenticated support route.
When the provider must handle it
A lost SIM, an actual cancellation, an unauthorised transaction, a refund request or an account fault requires the relevant provider. We cannot make those changes. For urgent or emergency assistance, use the appropriate service rather than this information line.
Content and privacy questions
You can also identify a page that appears inaccurate or ask about information you have voluntarily shared with this guidance service. Give the specific passage and an official source where possible. Ask the person handling a call about their information practices before disclosing personal details.
