The 4G service works well in Iphone 5, 5c and 5s so far. But, there was problem in iPhone 6 and above, because the update foe iPhone iOS was not provided now the wait is over.
Telecom operators all around the world must sign an agreement with Apple to enable their customers to use devices such as iPhone and iPad on their networks. NT apparently has not entered into such a deal. The agreement basically allows a telecom company to synchronise its network with Apple devices that run on iOS, paving the way for iPhone and iPad users to use 4G service on its network. NT has said it has already requested the American smartphone maker to enable the ‘location code’. Finally apple allowed NT for it's service.
