Wifi in Poland
 

Hi. This is my first post, so at the beginning I want to say hello :)

Recently, I started a new job and will often come to Poland. I need the Internet during my work, but also for myself, for private use.
Not permanently, because I will be in Poland once every two months. At most once a month.

I believe that you can help me :o

I think about two solutions:
1. Local SIM card.
2. Polish WiFi router

Can you advise me? Which SIM card do you recommend? Did any of you rent a Polish WiFi router?

Thanks for your help :D
