Top-up support varies by plan
The eSIM page checks whether that particular profile can receive an available top-up. The option may be unavailable because the plan does not support it, the eSIM needs activation first, the profile has expired or been cancelled, or a plan limit applies.
Availability can change. A data amount listed for new eSIM purchases is not proof that it can be added to an existing profile.
If your page asks you to activate first, follow the plan’s activation instructions. If it is expired, do not assume a payment can reactivate it.
Contact support if an active eSIM that previously showed top-ups no longer does. We can check the actual eligibility. If a new eSIM is needed, it will have its own installation details; keep the old profile until you no longer need it.
