Получение Башня GSM местоположение широта
Я хотел бы узнать способ или способ определения местоположения ячейки, к которой подключен мобильный телефон (GSM)

Есть ли что-то, что я могу сказать gsmLocation.getLatitude() или же gsmLocation.getLongitude()?

Чтобы узнать местоположение текущей ячейки GSM, вам нужна база данных идентификаторов ячеек и их местоположение. Если вы не являетесь оператором сети, нет действительно хорошего, авторитетного источника этой информации, потому что они не публикуют ее.
Если вы просто хотите определить местоположение устройства, попробуйте этот ТАК вопрос.
Продолжая то, что сказал @S List, вы должны подписаться на токен у следующих поставщиков API и убедиться, как работают точность / затраты.
