Getting a phone plan in America is relatively more confusing than that in Singapore. There are four main cell service providers in the United States: AT&T, T-Mobile, Verizon, and Sprint. These carriers own the wireless network infrastructure that they operate on.
Based on feedback from our students, it is advisable to use the networks of AT&T and Verizon since they have relatively better coverage here in Ithaca. Having said this, we have also heard that there might have been some infrastructure improvements on T-Mobile’s and Sprint’s network here in Ithaca, so these may also be viable options today.
