There are few LTE not-spots (i.e. countries with no launched LTE network of any kind – mobile or broadband fixed wireless) left in the world
Since our last report in January, new networks have been launched in Bosnia and Herzegovina, Burkina Faso, and Guinea, and we have identified small LTE network operators in Nauru, the Solomon Islands and Yemen
Most remaining LTE not-spots are remote island territories and states (of which there are around 23) or are countries in Africa: Central African Republic, Djibouti, Equatorial Guinea, Eritrea, Mauritania, Niger, South Sudan, and Western Sahara.
Other notable LTE not-spots are Cuba and North Korea
