alltel ppc6700 is a good one,but everytime I try to send sms always fail that popup error message tell there is a Error Class:Temporary,Cause Code:Othr.Netwk so I must connect internet first before sending sms,is anybody experience this problem ?

Are you certain that you have Text messaging on your plan?

yes and I already try to use my SIM card on regular cell phone and no problem at all,couple days ago I tell this problem to the seller they said it could be some provider jam or something,what a NICE answer.Until now I dont use keyboard much as I cant use to send text message like normal unless activated modem connection first before sending any text message.

Wait a minute. Did you just say you swapped your SIM card to test your account!? You do have a 6700, right?

Yea, isn't Alltel a CDMA provider?

No doubt it is 6700 CDMA,in RUIM version with possibility can change to different provider as many as you like.Sounds strange for you?or maybe this is the point of all,any different spec mine from yours (Intel PXA270 416MHz,MW 5,WiFi,Bluetooth,ROM date April 4 2006) almost forgot I'm from Asia,CDMA technology isnt very popular like GSM and its brand new for us.
