If fast data is not critical, tmobile'e $2/day option for unlimited calls, texts and 2G data, is actually a good deal. Plus, the sim can be had cheaply on ebay or one of the several stores. AT&t is not bad either. It's $0.10/cents min to anywhere in the US. Yes, incoming calls are not free, but there is a reason for that - It does not cost folks a HEFTY surcharge to call a US mobile (Receiving Party Pays), just like it does in other countries that have free incoming calls (Calling Party Pays).
