My buddy travels more than I and when the need arises he picks them up at the airport. Now the other options are to check with your current carrier but after a few trips I stopped buying SIMs.
Why? WhatsApp is what I use to call folk on travel.
I am traveling to Palermo, Sicily and looking to get an international SIM card. I will be travelling with an LG G4-H815, European phone (no locks). Need advice as to which prepaid SIM to purchase, will be travelling September 27 for a little more than one week. Need advice/suggestions. Where I will be staying has Wifi and not a tremendous data usage.
