Hi everyone! I will be heading to Poland in two weeks for around ten days. I will be in Poznan, Gdansk, Warschau and Krakau for travelling (the main purpose) and working (as freelancer). For working purpose, I need to be able to connect to internet for most of the time. So, could anyone give any advise which sim card and mobile data option should I get? It doesn’t have to be cheap, but it should have good coverage area and big data plan (around 3 - 5 GB). Thanks.
