I will be staying in New York City for a week, and I am wondering about Internet access. Using my own SIM it will cost me $26 / day for 50 MiB, then $3 for every MiB after that. That quickly becomes very expensive.
Is it possible to rent a wireless 4G router? Or can I get a prepaid SIM for this purpose? Are there other options for tourist Internet, many places with free wifi?
