In fact LMT provides a page to check whether your subscription includes access to LTE: https://www.lmt.lv/lv/4g-gatavibas-parbaude-0

Unfortunately the page is only in Latvian/Russian. Put the telephone number (as far as I remember) in the second text box, it will give you whether you can use 4G with current SIM card. If not, they will exchange you a new SIM card for free.
