You haven't given any details of the old and new SIM cards, but what you describe is typical of either a phone which is locked to an individual network, with a SIM of the "wrong" network inserted, or an inactive SIM card which has not yet been enabled by your network.

To cure the first fault, either revert to a SIM from the original network provider or pay to get the phone unlocked (you can either pay the network supplier it's currently locked to or you can use a phone unlocking shop. Sometimes the network option is cheaper and you certainly don't risk having your phone cloned and personal data copied by a dishonest shop proprietor).

The second fault may occur if you need to replace one SIM with another on the same network and same number. If that's the case, then you need to contact your network operator to deactivate the old SIM and activate the new one.

A third possibility, though less likely, is that you have a faulty SIM which need to be replaced.

There's a little symbol for an envelope -- how do I retrieve the message?

Envelope usually indicated a text message. Usually, if you have unread text messages your little envelope will have a number one or number two, etc in red on it.

You will need to go to your text message icon to open your text message screen.. It might be called *Inbox* but it's not email only text or SMS messages.

Why made phone early now cant just get busy signals?

Sounds like your phone or line is now short circuit and is holding the line so it appears busy to incoming callers. Try disconnecting the pnone and line right up to the incoming point of your house to find the problem.

Might be a problem with the network part. I mean the transceiver built in. Do another reset and see whether it fixed the phone. In most case, if the reset couldn't fix it, the problem might be hardware

When i call or text is says service unavailable or sometimes it says emergency calls only!

the problem with ur phone is if it is in a no call zone or if the bars on ur phone are a dark blue then u cant call or text and sometimes it will show a phone with a red line through it sometimes it is just where u r standing hope this helps and if worst comes to worst then you will have to take it in and get it replaced by ur insurance.

White screen with red and blue lines

Try removing the battery for a few seconds and see if that clears up the issue.

If it does, be aware that it's most likely a temporary fix. You'll want to go through the phone and clear out some of the memory (saved text message, call log, and even pictures if there are a lot of them). You might want to consider stopping in at your carrier's local store and getting the software flashed as well.
