Welcome to Data Sim, the one-stop-shop for 3, 4 and 5G sim cards. Data Sim has been in operation for over 10 years and our team have various experiences within the industry! Data Sim was created to fill a void within the industry, our original focus was tailored for BMS, CCTV’s and Industrial Clients, however, we have found that there was another void we could fill! The focus has moved to now include a range of popular data plans and some larger data plans that fill a hole in the market! Our sims come directly from Australia’s two biggest carriers and we have the majority of Australia covered with reception plans.
