Can I transfer my ATT tower phone to work on Verizon towers?

I bought a Samsung Galaxy Precedent on ebay. It's the 828C so it's supposed to work on verizon towers because it's a cdma. When I called Straight Talk to transfer my number they said that I couldn't do it because it is programmed to use Att towers. Anyway around this?

Anyone know how to build a Cell Phone Repeater or Booster for a tower?

I'd like an economical way (if that's possible) to build a cell phone repeater or booster that can work for multiple cell phones, and be mounted on top of a tree or some other tower or pole. (Boosting signals here is legal). The reason I'd like to do this is because we use a cabin that's located deep in the forest and currently cell phone signals are spotty. (Move down the road 100 feet or stand on a stump and it works, but not where you really need it to). My concern is for safety as many of my family members use this area, and if there were ever a problem, I'd like to know that we could get a call out for help. I've done quite a bit of searching on this already, and have found several methods to improve the cell phone antenna, or the coffee can method, but what I'd really like is something that can work for ALL of our cell phones (that are with different cell carriers), and therefore (as I understand it), can be on different frequencies. The only thing I could find were devices that were out of the box ready and at a hefty price. Does anyone have any advice? or can point me in the right direction in order to build something like this that will work? Thanks, canucksgirl Edit: Let me clarify that the intended purpose isn't to be able to contact 'emergency services' from camp. We're a few hours from the nearest town and it isn't conducive to 'sit and wait' for help to arrive. Our group has been extremely safe, competent and self sufficient in that area for more than 30 years. Without getting too personal, we have an "in town" family member with a serious illness. If there were ever a reason, we'd like to be able to reach family at the camp to let them know that they needed to return home.

Which cell network is better? Answered

Which cell network is better? At&t, or Verizon? Verizon just started service in our town, and they claim they own all the radio towers in the area after they purchased alltel. However, At&t has some good service too. I can get 5 bars in my bedroom. Any help? What I want you to consider: Phone selection, price of service, quality of service. Thanks!

Cell phone repeater for my home.

I'm looking into getting a cell repeater for my home. I live in a rural area with not a lot of service inside my house, but four bars outside. The repeater I'm looking at uses an omni directional antenna that draws in signal from multiple towers for multiple carriers. My question is, since this system uses an omni antenna, wouldn't any antenna do? Such as a CB antenna? The way I look at it the antenna draws in all types of signal but its left up to the inside receiver what type of signal to use? Am I wrong on this?

homemade signal booster? Answered

I was trying to figure out how to boast my signal coverage in my area, and a got an idea: to use a UHF amplifier, to pick up the towers signal and rebroadcast it. of coarse since things like WiFi, Bluetooth, and cellular 2G/3G/4G networks use two way radio, the signal can go back to the reviving end of the UHF amp, and get broadcasting to hit whatever tower. my phone should better recognize the tower, as if i just magically made a tower 2 feet away. however this might also amplify stay noise. if this idea doesn't work, why not? i think i am going to need at least a 20dB increase in power, but as of now i  need to do more research. but if i can buy a product that does a similar thing for less than $40, i would. http://en.wikipedia.org/wiki/Dead_zone_(cell_phone)#Dead_zones  http://en.wikipedia.org/wiki/Repeater http://en.wikipedia.org/wiki/Wireless_spectrum (cellphones use UHF spectrum) http://en.wikipedia.org/wiki/Signal_booster

Interfacing cell phone LCD's with VGA/DVI connectors

Anyone have any experience with this or know if such a connector/adaptor exists? I have a 320x240 display I pulled from a Blackberry 8700g and would like to run video on it off an old G4 tower. Thanks for any suggestions!

HELP: Measuring power density from cellphone tower.

I am working on a project to measure the power density from cell tower. Most projects I saw involve expensive antenna and also a spectrum analyser which is too costly. I came across showing ppl fabricating a target single band microstrip passing through a RF Detector circuit. I think chip like AD8318 could handle it?? But how am I gonna filter if were to use an antenna with range of 200MHz to 2GHz eg. (https://www.sparkfun.com/products/8347) to measure a specific GSM band like 900/1800 MHz from the cell tower? I need help on the filtering and RF detector circuit part!!The closest resemblance to my proposed system: https://www.favoriot.com/category/how-to/

SAMSUNG GALAXY SII SKYROCKET TROUBLE!!! INFURIATING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! PLEASE HELP!

I recently was given a samsung galaxy SII skyrocket that was being used on the AT&T network as a contract phone. I have a pay-as-you-go phone from straight talk wireless, which uses the GSM network on AT&T towers. Because of this, i thought that if i switched my SIM card from my previous phone into the Galaxy SII, it may work and function just like normal, since AT&T usually supports unlocking their phones and i know straight talk supports unlocked phones. To my surprise, and delight, it worked seamlessly for most aspects of the calling/texting portion of features. The only problem i've found is, despite both phones using the same towers and me paying for an unlimited data connection, the Galaxy SII refuses to pick up any kind of data connection or 3G signal. This means i cannot use many features of the phone itself, certain features of applications i have installed, or even get on facebook. however, the most annoying, frustrating, and honestly infuriating problem is; it won't let me send or download picture messages, which i do often!!! Is there any way i can get a data connection with the Galaxy SII without going back to my crappy old phone?????? or having to pay for an AT&T contract?!?!?!?!? PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Boosting broadband access from a usb modem?

How can I boost my broadband access from my usb modem? I am about 2 mi from nearest cell tower and I'm getting about 2 bars of national access to about 2 bars of broadband access (slow to medium speed). When I am in town by towers I get full 4 bars of broadband, (speed is phenomenal!) Is there anyway to boost my signal from home? Can I "ghetto" rig an antenna wire from usb modem antenna to the tv antenna on top of house? Any help appreciated... I have the USB720 modem from Verizon, and a new Dell Inspiron 1520 loaded with Windows Vista. Attached is modem specs from Verizon wireless. Thanx, The Revelator P.S. Hardline/fiber optics is not an option here, only cell phone access at house.

Is there technology to monitor a security camera remotely with no internet connection?

I have had a couple of robberies at my deceased grandfathers home, which is empty and no one is living there, and it is about 40 miles from my home. I was wondering if there might be a way to set up a camera and be able to monitor it at my home, either on my computer or my smartphone. I do still have the electricity going at his home, but I don't want to also pay for cable for an empty house(thus no internet connection). Just wondering if there is any technology available in which the camera could somehow broadcast over the cell phone network maybe? Any answers are greatly appreciated.

A few Nokia smartphone ideas and questions

Is there any free way to use a phone as a bluetooth mouse or keyboard? Perhaps VNC? I saw a comment somewhere with the idea of using the phone like an optical mouse. Anything that can do that? Also is there a way to get maps that use cell towers to track your position without using the internet to load the map? (I'm on prepaid and wap isn't cheap) Know of any must have apps for a Nokia N72? Thanks in advance

How can I fix the mobile antenna on my Cubot GT99?

So I bought a new GT99 (mtk6589 based) and put in a SIM card. No signal.... I checked for the signal strength and it says "0dbm, 99asu". All of my other phones work fine and the cell tower is just on the top of the hill so there is no reason for the phone to not pick up a signal. Even without a SIM card inserted, the phone should pick up a signal for emergency calls but there is no indication that there is a signal for that either. Does anyone know how to fix this?

Can these batteries be salvaged? Answered

I was given these two Gel batteries but they are not taking a charge. Is there some way to recondition them so they can be usable again? These were installed in a solar cell  and wind generator remote radio relay tower. They were new when put in. The wind charger was at first hooked up wrong (Not me who did that) and the batteries kept going flat until it was corrected. They did freeze once but after being pulled and brought inside they took a charge and worked just fine. They only had a few months of operation when the tower was blown down and the project was scrapped. The batteries and all the other stuff went into a store basement. Now, 2 years later, I am given these batteries but they will not charge. I don't know what might have happened to them in storage. Physically they are in perfect shape. I left one on a battery charger for 1 1/2 days and its still dead. My meter does show it has 10.3 volts across the terminals but there is no real amperage. The other one I put on a better charger and set it to recondition the battery. It ran for 24 hours and that one is also still dead.  These are sealed, non spillable, maintenance free batteries. Is there any way to bring them back from the dead and get them working again?

Jobmate cordless screwdriver

Hey guys!!! Long time no see, I have been busy doing other things in my life and coming to check on here completely slipped my mind, I feel so bad now after seeing how many comments I've missed out on replying on. Also, I noticed some people around here have a PRO beside their name, what is that about? Anyways I have a question I wanted to ask. I bought this handy little cordless screwdriver at a yard sale yesturday, and got it home, plugged it in to charge, and it seemed to be holding a good charge, I used it to change some tweeters in my tower speakers, it has good torque, and good speed. Overall, for $1 I was happy with my find while out on my little adventures. Well, I went to use it this afternoon, and it was dead :( Apparently the Ni-Cads are toast. The problem here is, theres only one screw in the side of the unit, and it only lets me pry half of it open, I can't get the top off of it, there seems to be two metal tubes holding the top on. Does anyone have any idea how I'd pop this thing open?? I want to see about replacing the two cells inside with some rechargeable energizer AA's I have, would I not be able to charge them with the built in charger?? They are NiMh however..
