I will be visiting Western Ukraine in early March. It's essential that I have mobile internet access on the go.
What mobile sim card should I ask for? I will be making ZERO calls (unless there is some major emergency back home) but I do use a lot of data on these trips. Just need access for 1 week.
It may be asking too much but I don't suppose there's a sim card that will suit my purposes and function both in Poland AND Ukraine??
