You need to contact your phone service provider (PSP) to configure your phone. They need to modify some settings on it.

I can receive text but cant send.....says protocal error...unspecified i have reset the phone and still nothing was workin fine yesterday

Hi the problem you are having is with your message center number this is a common problem and usually happens after you have changed your sim card to another network all you need to do to solve this problem is call your service provider and tell them the make and model of phone you have then ask them for the correct message center number.
they wont charge for this and they will tell you how to set it up, you will also need to ask them to send you the latest wap and mms settings so you can use the net and send and receive picture messages. they wont charge for this either and they will send you these settings via txt message and this will then update your phone to the latest settings.

let me know if you need further assistance ok

plz rate this solution as i have a whole page of unrated posts, thanks

My pantech slate isn't allowing me to send texts, It says text message full but everytihng is empty How to i get it to work??

First make sure your outbox for txt messages has been cleared.

There's 2 different places SMS messages are stored. When they get to your phone, they come in through the SIM card. Then the phone reads it off the SIM card. Some phones delete the messages off the SIM card after the phone reads them, some leave them on the SIM card.

Look around in the options for SMS messaging on your phone for something related to this.

It might be that you dont have internet connection turned on.
Call ATT tech support at 611 and ask if your internet is working.
