The Croatian SIM card is one option. I don't want to highlight it here so much as it may kill the deal, but generally for roaming in Europe it's very good.

The important specs about your Samsung Galaxy is not that it works on 3G and 4G/LTE, but on which frequency bands. Here Phonearena says for LTE bands: 1, 3, 5, 7, 8, 18. In the Baltic States bands 1, 3, 7 and 20 are used. 3G looks good. So you are only missing band 20 (800 MHz) on LTE. This means that you will have a good 3G/4G coverage in towns, but may be some 4G gaps on the countryside.

As SIM cards are so cheap in the countries and data as well, it might be a good idea to buy a SIM in every Baltic State that you visit, because they have mostly not implemented "Roam like at home" yet.
