You will receive a SIM card has been delivered, what can you break out as a normal Sim, Sim Nano or Micro Sim either. Then you go on to the WhatsApp website and there carries the necessary information for activating a (your personal data, the PUK2 of the map). You have to agree there does not necessarily mean that your data may be used for Maktforschungszwecken. So then do not tick there.
Then you get a confirmation email. The activation of the SIM has taken place said up to 4 hours, with me about 34 hours. You will receive an email with your new phone number and the same thing again by post.
If ye then be registered on the website can book your WhatsApp there new options and add credit. Or you can watch there how much units to surf you have left, SMS, telephony.
I have followed the WhatsApp app downloaded Sim me on my cell phone. Which is much more practical in my opinion. There you can easily book or stonieren if you do not have the mood to automatic renewal is an option. And you can see how much credit / Euro you on the phone and the term of the option reserved.
When activating the SIM to the WhatsApp website you can sign my referral code to get paid so 10 Euro credit. I get paid even 10 Euro credit. According to the email I received that lasts 2-3 weeks. Here's my recommendation Code: 14BB8D033
PS Addicted off you at the "Mobile data" on your cell phone when you just do not want to use the mobile Internet. As long as this is off you can only with WLAN. Otherwise, the phone (eg for your apps) can sometimes automatically download something that the 600 units (megabytes) claimed this WhatsApp option.
