NO, Lesotho (kingdom entirely landlocked within South Africa, nicknamed the Kingdom in the Sky for its altitude) is outside the EU — telecom roaming is billed at high rates with your usual carrier. The Alosea Lesotho eSIM is essential for trekkers (the entire country is above 1,400 m, highest point Thabana Ntlenyana 3,482 m) or unique high-altitude skiing in southern Africa at Afriski. You connect to Vodacom Lesotho or Econet Telecom Lesotho upon landing at Maseru Moshoeshoe I (MSU).
