We are transferring everyone to our new network. The new network has many advantages such as 4G roaming in the EU and you will be using the best tested network in the Netherlands. We have done everything we can to make sure the transfer goes smoothly. I can make sure your SIM card will be activated as soon as possible. Send me your 06-number and the SIM card number in a private message and I'll make sure your SIM card is activated as soon as possible!
I'm here for you!
