I have finally found the answer!!!
Depending on you service provider the phone will run on certain tri or quad brands. ( i think thats what they are called.)
like if you go to www.gsmarena.com it will say the network it runs on
for example 850/900/1800/1900
Samsung u700 doesnt run on 850 so if your service provider doesnt support 850 than thats why.
i believe that AT&T runs 850 and T-Mobile can support 900 or greater.
Um correct me if i am wrong
