I want to buy MAX-HD2-LTE-VA-T! Will he work in Ukraine?
This model is based for US region bands(LTE B4/1700, B17/700 and B13/700) which could be not available in Ukraine based per checking at https://www.frequencycheck.com/countries/ukraine
You will need to select MAX-HD2-LTE-E-T(Europe/International) or MAX-HD2-LTEA-W-T(Americas/EMEA) models.
Device models and supported bands could be found at Ordering Information section: https://www.peplink.com/products/max-cellular-router/multi-cellular/#hd2
