A Digi top up usually means adding credit to a prepaid Digi SIM in Spain, and less often in Malaysia or Belize, three networks that share a brand but not a system. doctorSIM has topped up prepaid phones since 2006, and you can do it here in a couple of minutes.
Where you can top up Digi
doctorSIM tops up Digi prepaid lines in three countries: Digi Spain, Digi Malaysia and Digi Belize. Choose the page for the country where the SIM itself is registered, not the country you're paying from: a Digi Spain number and a Digi Malaysia number sit on separate networks, so each has its own top up.
Recharging a Digi Spain line from outside Spain
Most searches for a Digi top up are about the Spain network, often from someone living outside Spain who wants to add credit to a relative's line or to a number they use themselves when travelling. You don't need to register the SIM in your name or open an account first: just enter the phone number, pick the amount and pay. The credit reaches the handset directly and you get a receipt by email, so both of you know it went through.
Frequently asked questions
How do I top up a Digi prepaid SIM?
Go to the country page for where the SIM is registered, enter the phone number, choose the amount and pay by card, PayPal, Apple Pay or Google Pay; the credit lands on the phone within seconds.
Can I top up Digi Spain if I'm not in Spain?
Yes. The top up follows the phone number, not your location, so you can pay from any country and the credit still reaches the Digi Spain line.
Do I need the Digi line to be in my own name?
No. Any Digi prepaid number can be topped up regardless of whose name it's registered under.
Is a Digi Malaysia top up the same as Digi Spain?
No, they're separate networks: use the Digi Malaysia page for a Malaysian number and the Digi Spain page for a Spanish one, since a top up on one doesn't reach the other.
