Hi,
Is there an updated thread of the best prepaid sim in USA? Or unlimited for 2 weeks or something?
Depends what you need.
If you need unlimited talk/text/international calling to many countries (including Israel)/500MB data with ATT service, preloaded H2O sim on eBay is the way to go. If you're going to stay in city, don't need international talking, and/or want more data, search for simple mobile preloaded or page plus (if you have Verizon lte phone) preloaded.
