I am incredibly disappointed in Telestial.com.  I do not recommend using them.  I placed an order to rent a phone for some international travel on 23 Dec. 2008.  I indicated on the order form that I needed the phone delivered on 02 Jan 2009 (my flight departs very early on  05 Jan 2009).  The order came back w/ a 3-business day shipping at a charge of $16.  Shouldn't be a problem, right?  The website clearly says that phones shipped by 3 business days come via Fed Ex.  I just called to check on the status of the phone, had it been shipped, and could I get a fed ex tracking #.  I was informed that the phone was shipped by UPS (not FedEx) and would not arrive until 05 Jan 2009 by 4:30PM.  Obviously after I will have departed.  So, they didn't follow their own business practices as outlined on their website.  I politely asked them to put a phone into FedEx for me w/ next day delivery at their cost because of their mistake, and they refused!  They may have "saved" themselves a couple of bucks by using UPS instead of Fed Ex, but they have lost me as a customer FOREVER!  You can't rely on this company to deliver on time.  BE FOREWARNED AND STAY AWAY!!!!
