About ByteSim

10 of 12 facts confirmed

Still researching: Legal entity · ID verification

Founded: 2022
Headquarters: Wan Chai, Hong Kong
Website: bytesim.com
Refund policy: Full or partial refund for connection issues, depending on the situation; no cancellation fees and a money-back guarantee (ByteSIM FAQ). Full terms are on their Refunds Policy page. Read the policy ↗
Validity starts: Most plans start when the eSIM first connects to a network at the destination; some start on a selected date, in the app or (e.g. the Giffgaff UK eSIM) from purchase, as stated on the product page. Installing early usually does not start the plan; some QR codes must be used within 180 days.
Fair-use limit: Unlimited plans may be subject to a local operator fair-use policy: heavy use in a short period can be temporarily slowed or deprioritised (1080p streaming still possible), lifted the following day. The per-plan speed policy is stated on each product page.
Top-ups & rollover: No top-ups or extensions: data on an existing eSIM cannot be renewed; buy a new eSIM when you need more (ByteSIM FAQ: not supported due to the anonymous nature of their eSIM products).
Lost device / reinstalling: A QR code binds to the first phone that scans it and cannot be scanned by another; most profiles are not transferable or reinstallable after deletion, so contact support before changing or resetting a phone (depends on the plan). A lost QR code can be viewed again in the app.
Billing currency: Prices and checkout are in USD for every storefront country (the site's country selector lists USD $ throughout).
Support: WhatsApp · Email · Help center · 24/7
Payment: Apple Pay · PayPal
