Transfer Smartphone Contacts to Nokia C5?

I want to camp with my son for a week and not have to charge my smartphone every day. So I bought (in a nostalgic fit) an old C5 from Nokia. How do I get my phone contacts from Huawei to Nokia with Nokia Suite or Nokia PC Suite or thunderbird (no Outlook) or another downloadable tool?

I hope somebody can help me over the next three weeks.

With my Huawei P9 you can set whether the contacts should be saved on Google, on the phone memory or on the SIM card. However, this is only possible when saving for the first time; I have not found a way to change that, because so you get the contacts on it, you would have to save all on the SIM card and then put the SIM card in the Nokia C5. Then there would be all the contacts on it.

But I do not know a tool to transfer that.

A heartfelt thank you,
I'll see if it works out: so far I had the contacts stored only on the SD card. I'm just afraid that the Android logic is different here than the C5. I would probably have to save the contacts as VCard and that does not work properly, or the Huawei exports only one data block that can't be separated into individual VCards - or at least not from me and with my means ;-)
