What changes, and what doesn't
You register on your brand's portal as usual. If that brand has roaming enabled, a roaming token linked to your account is automatically issued — it's not a separate physical card, it's the same identifier working in more places.
When you arrive at another Hub brand's charger, the system recognises your token and authorises the session exactly as your own brand would. You don't need to create a new account with that brand or re-enter your payment details.
Who charges you
Even when you charge at another brand's charger, it's still your brand that bills you, using the card you already have saved in your portal — not the brand that owns the charger. The session appears in your regular history, just like any other.
Finding somewhere to charge
Your portal map shows not only your brand's own chargers, but also all the chargers across the Hub network it's connected to — so you know in advance whether you'll have coverage at your destination, not just within your usual area.
Not every brand has roaming enabled
Enabling roaming is each brand's own decision, not something that happens automatically. If your brand hasn't enabled it, your portal will still work as normal — just limited to its own chargers.
