hello, I have 2 questions,
first , I use freenet-funk but I want to transfer my number to o2 by buying this phone : “Samsung Galaxy S20+ mit Tablet” . But I did not see an option for that when ordering. How do I transfer my number,? before or after I ordered and received my phone and sim ?
and second, if I choose 20 gb datenvolumen and then when i need more can i upgrade my tariff?
waiting for your answer. thanks in advance!
Hi
thanks for your interest in our products 
The option to import your number should pop up in the order process.
If it didn´t, activate the card after you´ve received it, register here (click me) and open this page after that:

We will then check the details and the status of the given number, set the date and inform you along the way 
Viele Grüße,
Kurt
