No KYC or KYB is required by Portproof to buy listed products. Email confirmation is optional. The payment provider may require its own checks. Product availability, plan conditions and account limits still apply.
Plan selection
Check that your device is unlocked and supports eSIM. The installation guide helps you check compatibility; a supported device is separate from a plan’s coverage.
Read the selected plan’s activation policy before installing. Validity may start on installation or on connection, depending on that plan; installing before departure is not a universal rule.
Japan coverage can appear in a single-country or regional plan. Open the covered-country list for every destination you need. Coverage alone does not identify the local carrier, routing location or speed.
Check the reported calls, SMS, hotspot and top-up features on the selected plan. An eSIM’s mobile data does not by itself promise a carrier phone number or SMS service.

Check the delivered installation details and plan status in My eSIMs. A processing order does not mean the profile is ready. Follow the selected plan’s instructions before changing roaming or network settings. For a customer-requested refund, confirm your account email and submit a request for owner review; approval is separate from a refund or payout. Read the refund policy.
