Hi. A friend of mine is coming to Hamburg and is working here for around one week. He will need a mobile internet connection with around 5gb because his work requires for him to be constantly uploading and downloading material on the go.



I have a prepaid O2 sim-card that I am not currently using so I told him I could give him this card for him to use while he is here.



I now have two questions:



1. He will need some kind of receipt to give to his boss when he goes back so he can justify the mobile internet costs. How can I get something like that? When I charge my prepaid card I only get a confirmation SMS and I don't know where to get a payment receipt.



2. He has a budget of 50€ to spend and he wants to have around 5gb. The highest Tarif I find is 1,5gb for 19,99€. Is there any way to get 5gb without constant recharges?



I wanted to post this on the O2 English Community but somehow I cant do it (the option is grayed out and I can only post in "Prepaid")



Thank you.
