It's hard to give a recommendation based on your given facts. There are contracts which can be terminated at the end of each month by O2 or WinSIM and others. The big difference is your Swiss data needs as this can be charged very high (up 100 times of German data). With Vodafone you have Switzerland only included in "Reisepakete" on contract. On Prepaid = CallYa, it is not. With Lycamobile you can add one of their new EU roaming packs which is much cheaper for roaming. But strictly no tethering with them. Another alternative is an Aldi mobil oder Lidl SIM. Their roaming packs are mentioned in the article above.
