First of all,it sounds like you have a defective phone... that has the same problems that the Samsung X426 had for AT&T Wireless. Since the warranty is through the manufacturer, you should probably contact them. Although... from what I keep hearing from people who think Sprint is a greater thing than sliced bread, if you go to a direct dealer, they may exchange the phone for you (probably for the same model). I would check with a local direct dealer or call their customer care line to see if they will swap it for you. Otherwise, Samsung may be the company to call.
As for getting another phone... you can probably buy one on eBay or by private sale from someone w/ a Sprint phone to sell. I actually had one about 6 months ago that I could get to you... but I don't have it anymore. Also, direct dealers may be able to get you a better price than an indirect dealer at a kiosk. You could ask customer care when you call them about your current phone.
So I recently got a plan with Sprint PCS (this January) and with my plan got the Samsung VGA1000. I have no qualms with my service from Sprint, but the phone is just terrible. It is great at everything but being a phone. I can hear other people all right, but my voice is incredibly muffled.... terribly so. Everyone complains when I talk to them, and unless I shout, no one can hear me. I used to have an old Nokia (don't remember the model) and I never had to talk that loud.
Now the reviews seem to state differently, so I have two questions:
1) If it is just my phone, is there anything I can do? Ask Sprint or Samsung to see if it is defective? How would I do that?
2) If I get a new phone, none of the models Sprint offered at their kiosk appealed to me (they were too expensive and I would rather get a Nokia again). However, it seems like in this country, you HAVE to buy a phone through a service provider. Is this the case? Can't I just buy a phone from someone else and then tell Spring and have them transfer the number to that phone? (Soooo much easier in the rest of the world with SIM cards). Anyway, I am not sure how it works in this country. I looked at phone at nokia.com and everything there seemed like it had to be purchased with a service plan from another carrier.
Any help on these two issues would be much appreciated. Thanks!
