I purchased a Nokia 5 from Bangladesh. Now I am in USA with this phone in New York City. But my nokia5 mobile do not support LTE network. But I get 4G network in Bangladesh. So, internet is very very slow in USA, no LTE or 4G network in my phone, also this type network is available in another phone. What I will do? Is it possible to get LTE or 4G network my Nokia 5 phone which is purched from Bangladesh?
