Do German hotels have wifi?

Most WIFI in Germany have passwords, and only some public places have free WIFI.

If it's only two weeks, I suggest you start international roaming. It seems that it is only more than 2 yuan or 3 yuan a minute. Anyway, you don't need it, and the money can't be spent.

German mobile phone cards will be more convenient, but mobile phone cards with prepaid phone bills will never return with 3G Internet access.

What if you haven't run out of money in two weeks? I can't use it either.

There is also a German mobile phone card on Taobao. If not, buy one. This is what foreign students who have just arrived use.

Personally, I don't think it would be so troublesome if I just reported my peace. International roaming is not so expensive now, and there is no need to send airmail. Just send a message. Go back to the hotel at night, some hotels have WIFI, and then leave a message on QQ, and it will be OK.
