AT&T, Sprint, T-Mobile, and Verizon are the big 4 phone companies in the USA.
I am trying to find out which provider has the best coverage (the USA Telstra equivalent I guess) across the USA. I am looking for a prepaid SIM that will be used for a massive road trip (25states+) across the USA. Cost isn't a factor.
Anyone have any insight or experiences?
which handset are you using? and by coverage do you mean data or voice? do you have any specific data requirements (speed or volume)?
