Can German mobile phones be used in Holland? How much do you charge for answering the phone, making phone calls and sending text messages?

Yes, I can use it. Traveling in April, leaving Germany will send text messages. My card is O2, and it's cheaper to call 55 cents to answer the phone. Or 3 1. I forgot that the original network package can't be used, because when I went abroad, it was foreign telecommunications and I couldn't get on the Internet. I really forgot to send a message. ...
