Self-service · Top-up

Top-up airtime

If your SIM is active with us, top-ups are usually instant. Most can be done online; complex or pooled plans go through the hotline.

How to top up

Most top-ups can be processed online. We’ll need:

  • The satellite phone number or SIM serial (ICCID)
  • The voucher value (or recurring plan amount) you want
  • A credit/debit card or invoiced account

Once we have the request, top-ups are usually live within minutes for prepaid plans, and within an hour for monthly plans.

How to do it

Renewals and auto top-up

If you’re on a monthly plan, renewal is automatic. If you’d like an auto top-up arrangement — for example, “add 100 prepaid units whenever balance falls below 50” — we can put that in place. Ask us.

Lost the receipt?

We can resend any top-up receipt from our records. Drop us a note with the phone number and the rough date of the transaction.
