Question about Cell Phones

3 Answers

I am trying to put an extended NNTN5539A antenna on my i355 phone, but I can't figure out how to remove the original antenna. I saw on one forum where someone said there was a tool to remove it, then I saw somewhere else that someone said to use a small screw driver. Neither gave very much details, so I'm still lost. Please help!

Country John doesn't know what he is talking about. There is absolutely no need to be taking the handset apart like that. Removing the original antenna and installing a new one is a very simple process and requires nothing more than a small screwdriver. You are likely to damage the locking tabs and/or seals on the handset case following his lame instructions.

First, pull the retractable antenna out about halfway, so you can flex the antenna to one side or another. Look into the shaft housing the antenna and you will see grooves in the interior. Using a small screwdriver, insert the screwdriver into the antenna shaft and unscrew it. Once it's unscrewed, you will be able to remove the antenna assembly. There will be a plastic sleeve for the retractable antenna, that should drop out if it didn't remain attached to the antenna assembly.

Installing the NNTN5539A is simply a matter of screwing it on by hand.

It's simple. In order to install the antenna, you must do the following:

Using a very small "star" type screwdriver, remove three screws from the base of the unit. Remove the base trim piece. The body of the phone is in two pieces (front and back). Use a knife to separate the pieces by first GENTLY lifting the locking tabs on the bottom of the unit so that they will easily unsnap by themselves, just lift them a little bit, not all the way. Insert the blade along the side of the seam and pry gently.

Slowly remove the back. There will be adhesive tape at the top piece, so work slowly. Notice the locking tabs on the sides, they will come apart by themselves, no need to worry about it.

After separating the halves, unscrew the top of the original antenna, screw the new antenna in place, slide the back atenna opening over the new antenna and snap into place, making certain that the side tabs insert properly. Just use your eyes and common sense. Do not force anything, but snapping the halves back together will require a firm force.

Replace the bottom trim piece and three screws, you're done!

    Nonsense, this will lead to damage to the handset, and is completely unnecessary. Stick to giving fixes for gear you actually know something about.

My phone is restricted. It says "ready" on the display. How do I unrestrict it?

You are having an issue with your service. Nothing you can do manually. Call Nextel. If your carrier, "Nextel" isn't present on the display then you have a service issue. Ready means that an emergency call will work but you can't make or receive calls.
