Simpel manages prepaid and sim-only usage in the Mijn Simpel app. There is no useful public USSD list.
| What you need | How |
|---|---|
| My number, balance, data | Mijn Simpel app |
| Fallback for your number | Phone settings (iPhone / Android) |
| Top up / change plan | Mijn Simpel app or simpel.nl |
Shortcodes can change. If a code does nothing, use the official app or the phone settings methods below.
Find your number without a code
- iPhone: Settings → Phone → My Number
- Android: Settings → About phone → Status / SIM status → Phone number
- Ask a friend to call you, or call yourself from another phone
If your phone will not register on the network at all, the SIM codes will not work until the handset is fixed. Blue Apple repairs phones in Amsterdam Zuid — see all repairs.
