Frequently asked questions
How do I insert the SIM card in my phone?
Insert the SIM card into your mobile phone and turn the phone on (see the manual of your mobile phone for instructions if necessary).
When your mobile phone is turned on, you are prompted to enter your PIN. By defaults the PIN is set to 0000. After entering your PIN, you can instantly call and receive calls and SMS, with your FREE credit (if applicable: € 7.50 + € 7.50 FREE call credit after registration on the website and first upgrading) .
If on your mobile phone, the message "SIM card rejected" appears, your phone is probably equipped with a SIM lock. Look below on What is a SIM lock and how can I remove it? for solving this problem.
What is a PIN code?
The SIM card is protected by a PIN code of 4 digits. The PIN code is by default set to 0000, but you are advised to change it. If your PIN code is incorrectly typed in three times in succession, the SIM card is automatically blocked. Also you have a personal voicemail PIN code, you need to access your voicemail from another phone to listen.
How do I change my PIN?
We recommend using a personal PIN code to enter your SIM card against abuse. You can create your own PIN code as follows:
Step 1. Press ** 04 # followed by the current PIN code. This by default is 0000.
Step 2. Press *, enter your new PIN, press * and enter your new PIN code again.
Step 3. Press the # key to confirm. Your new PIN code is now set.
If you enter your PIN code incorrectly three times in succession, the SIM card will be automatically blocked. To unlock the SIM card, go to What is a SIM lock and how can I remove it?
What is a PUK code?
Your PUK code is indicated on the letter you received with your SIM card.

There may be a SIM lock on your phone. This digital lock ensures that you cannot call with your prepaid SIM card.
To know if your phone has a SIM lock, insert the SIM card in your mobile phone. If (after you have turned on the phone and have entered the PIN) the message 'SIM refused' appears, your phone is probably SIM-locked.
Your previous provider can easily remove this for you. If your phone is older than one year, this service is free. When the phone is less than one year old, ask your previous provider about the costs of removing the SIM lock. Your SIM lock can only be removed by your previous provider.
