Okay - I have a Verizon Samsung Galaxy 10.1 tablet. I mainly use Wi-Fi for data here in the US, but will be using cellular network for data in Europe if Wi-Fi is not available or not robust.
Can I buy a data SIM card in Europe (or online before I go - any recommendations?) and replace the VZ SIM in the tablet to access local cellular networks for data. Is it more complicated than merely taking out the VZ SIM and replacing it with the Europe SIM?
Verizon global data is $25 per 100MB.

I'm assuming that a local SIM card would provide cheaper data costs.
Thanks
