After having done the research, decided to get Sprint service and purchased two TP5200 phones and subscribe to Family plan. The selling point was 14 days satisfaction guaranty. It turned out that one of the phones was not holding the cahrge the other one failed the "signal reception test" which both performed by the Sprint store technicians. We were offered replacement of a lesser or equivalent value phones since they didn't have them in stock. Considering the fact that there were no chance of getting any reception in any building we have been (UCSD area) we decided to returned them. My wife had to go out to the parking lot to make phone calls from the hotel in Sacremento. On campus, even outside, if I were to move few steps I would loose connection.... They took the phones back. Turns out I had to call SPrint to cancel the service contract. I didn't have to call Sprint to sign up but now I had to! I did. After 50minutes of holding a rep with a nasty attitude informed me about all the cahrges which I will be billed for including but not limited to sign up fee of $35 for each line. There was no point of arguing and I hung up. It appears to me that the wireless providers covered all corners and they know how to screw their customers with or without a service. I, as for one, am done once, and not going to have a cellular service till they meet at least European standards of cellular service. I now fell better having had the steam off.
