How do i get my sprint phone to work on wi-fi ?


sprint phone or samsung ?
Sprint offers high-speed WiFi service for existing Nextel customers, and provides an extensive network of hotspots in the United States at locations commonly frequented by business travelers, such as hotels, airports and conference centers.
Getting Sprint WiFi requires a Nextel customer account, connection-management software, a MyNextel user account and a computer that supports high-speed broadband.
Sprint WiFi plans include an unlimited WiFi hotspot and an unlimited PC access plan with a WiFi hotspot package.

Sign up for WiFi service through Nextel by calling 1-800-SPRINT1.
Download and install the Nextel Connection Manager software.
Nextel offers the WiFi version of the connection-management software at the Sprint Nextel website (see Resources).
Register your account via MyNextel on the Sprint Nextel website (see Below).

Samsung Epic 4G Phone into a Wi-Fi Hotspot

The Samsung Epic 4G smart phone allows you to convert your phone into a Wi-Fi hotspot and connect up to five devices.
Such a set-up will keep you from running around searching for an area that offers free Wi-FI. If you're stuck in an airport or staying overnight at a hotel, you won't have to pay extra for Internet service.
You can connect your laptop or other media device to your phone's Wi-Fi network.

Press the "Home" button, which looks like the outline of a house, on the bottom of your Samsung Epic 4G phone.
Click the "Menu" button to the left of the "Home" button.

Click the "Settings" icon, which looks like a gray box with a spoke in the middle.


Scroll through the list and click "Wireless & Networks."


Press "4G" until a check mark appears, indicating the 4G network is enabled.


Click the "Home" button.
The 4G icon will appear to the left of your signal bars in the upper-right corner of your screen.
The separate sets of bars above the 4G logo indicate the strength of your 4G signal.
When the bars above the 4G logo are completely gray and the 4G logo is white, you have a weak signal.
When you are no longer receiving a 4G signal, your 4G logo will be gray and a 3G logo will appear, indicating that the 3G network is now enabled. If both of the logos disappear, you are not receiving any signal.
You must have either a 3G or a 4G signal to use your phone as a Wi-Fi hotspot.

Enable Sprint Hotspot
Press the "Applications" icon, a blue box with four whites squares in it, in the lower-right corner of your Samsung Epic 4G phone.

Press the "Sprint Hotspot" icon, which looks like a phone with two signal bars on the right side, until a check mark appears to the right of the icon, signaling the Spring hotspot function is enabled.
A pass-key allowing you to connect other devices to the phone's network will appear on the screen.
Write the pass-key down.


Enable Wi-Fi on your laptop or other device that you want to tether to your Samsung Epic 4G phone.


Search for the Wi-Fi network affiliated with your Samsung Epic 4G phone.
The name of the network will begin with "SPH-D700XXX."
To change the name of the Wi-Fi network affiliated with your Samsung Epic 4G phone, press the "Menu" button; the "Settings" icon; and "Device Name." Enter the new name for phone's Wi-Fi network.


Click the network affiliated with your Samsung Epic 4G phone on the device you want to tether to your phone'ss Wi-Fii network.
Enter the pass-key, and click "OK."
Your device will now be tethered to the Wi-Fi hotspot on your Samsung Epic 4G phone.

What is 3G?


Hi there. 3G is the network your phone is on. Your carrier (like Orange, or AT&T) provides the 3G network for your phone to connect to. What 3G means is that you have a signal from your phone with an active voice and data connection. 3G is faster than the old EDGE network, but slower than the most current 4G networks. Basically, as long as you have the 3G logo on your phone (with a capital G) you have access to the internet and applications that need data to function will work. I hope that helps! Alex

No 3gs icon on screen, slow connection


You are most likely in an area that has little to no 3G signal, hence your phone has reverted back to the more reliable (however slow) Edge data connection. Please refer to this guide for a reference. Blue refers to 3G network while orange refers to the Edge network. sellers737.jpg

I forgot my iPhone Passcode. What can I do to unlock it?


iPhone setting:*
- Auto-Lock: 1 Minute;*
- Passcode Lock: On, require passcode immediately, after 15 min or 4 hours etc;*
- Network: Turn 3G Off

Scenario 1: Home screen is active with screen on*
1. Press power button for seconds until asked to '"slide to power off"
2. Slide to power off
3. press power button to turn on iPhone
4.*When asked to enter passcode, touch the "Cancel" key, then slide to unlock
5. bypassed passcode

Scenario 2:*
1. On the screen of being asked to enter passcode, press power button for seconds until asked to '"slide to power off"
2.*Slide to power off
3. press power button to turn on iPhone
4.*When asked to enter passcode, DO NOT touch any key on the screen, press power button for seconds until asked to '"slide to power off"
5. Slide to power off
6. press power button to turn on iPhone
7.*When asked to enter passcode, touch the "Cancel" key on the right bottom corner, then slide to unlock
8. bypassed passcode

Notes:
1. When Network setting changes to Enable 3G: ON, "3G" signal shows up, passcode CANNOT be passed through
Go to a underground parking lot or a lift where 3G signal is weak, when 3G signal switches to "E" (Edge), passcode CAN be passed through following above steps
2. When no 3G or Edge signal, above steps don't work

Conclusion:
Seems passcode security is related to network status
Possible security hole under Edge

I charge my i phone over night and after a few hours the battery dies


you should try turning your wifi off, and disable 3g

if you dont know how; just go to settings, general, then network. you'll see the option to disable Wifi if its enabled, as well as 3G. If you have 3G enabled, your iphone will die within 5 hours!! You can tell if your phone is on 3G mode by looking at the top left of it next to your signal bar, and see if there is an "E", a signal strength bar (Wifi), or an E, which is just the standard At&t network that takes less juice to run.

Try it lol

Nokia n 73 signal disappear


Sounds like you're getting 3G interference. It happens because you're just on the edge of a 3G area. The same happens to me on both my N95-8GB and N73. The phone is detecting a weak 3G but it's not enough to make a call.
You need to go to "Tools" -> "Settings" -> "Network" and switch from "Dual mode" to "GSM" The phone will say it needs to restart, select "Yes"
The phone will then restart and you shouldn't suffer any more 3G blackouts.

Hope that helps.

Letter h


i have that one too.. yes, it stands for High-Speed Downlink Packet Access (HSDPA) for a 3G mobiles. i had network problems/signal issues weeks ago when i used that setting, so i changed my phone setting from 3G to GSM. [uhm..i don't think you can find that in the user guide either, hehe. you have to browse and make yourself familiar w/ your phone=) ] with that i don't think i can make video calls, but who cares.. my signal issues were resolved. now, whenever i switch back to 3g, i can still see my signal bar on the upper left fluctuates.. sigh ;c

anyways, you can make that "H" disappear by going to:
settings=
connectivity=
mobile networks=
gsm/3g networks=
then choose GSM only.
