I have had this same problem with Straight Talk before.

First, I would call them up because it would appears that sometimes, Straight Talk does not turn on the internet/picture messaging when doing the activations and they go amiss.

If you have wi-fi in your home or, if you are in a wi-fi hotspot, I would try sending a picture when you are own your own wi-fi or in a wi-fi hotspot. To do this, make sure your "Wi-fi" is turned "On" in the settings menu on your phone.

By having the "Wif-fi" turned to the on position, you can also save on your data usage by using your own wi-fi and various hotspots so you are not eating up your own data. I'm always surprised at how many people do not know this.

So check to see that "Wi-fi" is turned on in your settings and, send a picture over your wi-fi or a hotspot wi-fi. If you are able to send a picture over your wi-fi or hotspot wi-fi then you know that it's a problem with their network and at that point, I would cal Straight Talk and tell them that you are unable to send or receive pictures.

Hello,

You have to ocnnect your iphone to internet first , Follow below step to connect to internet

When you use any Internet enabled application, iPhone does the following in order until connected:

1. Connects over the last Wi-Fi network you used that's available.
2. If no Wi-Fi networks you've used are available, shows a list of Wi-Fi networks in range. Tap a network and, if necessary, enter the password to join. Networks that require a password show next to them.
3. If no Wi-Fi networks are available or you choose not to join any, iPhone connects over the cellular data network.

Note: You can be on a call and use Wi-Fi or 3G1 at the same time. Other cellular data networks are unavailable while you're on a call.
Wi-Fi

• Wi-Fi is often faster than cellular data networks. Wi-Fi networks cover limited areas. iPhone can join AirPort and other Wi-Fi networks at home, at work, or at Wi-Fi hot spots around the world.
  When iPhone is connected to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows connection strength. The more bars you see, the stronger the connection.
• To see all the Wi-Fi networks in range, from the Home screen choose Settings > Wi-Fi. Tap a network to join it.
• Many Wi-Fi networks can be used free of charge, and some require a fee. To join a Wi-Fi network at a hot spot where charges apply, in most cases you can open Safari to see a webpage that allows you to sign up for service.

For information about configuring Wi-Fi settings, see the "Wi-Fi" section of the iPhone User's Guide.
Note: iOS devices sold in China may use the term Wireless LAN (WLAN) instead of Wi-Fi. Not all China iPhone models support WLAN; see this article for more information.
Cellular data networks

• Cellular data networks allow Internet connectivity over the cellular network. Check your carrier's network coverage in your area for availability.
  You can tell iPhone is connected to the Internet over a cellular data network if you see , or in the status bar at the top of the screen.
  If you're outside your carrier's network, you may be able to use a cellular data network from another carrier. Roaming charges may apply.
  Note: If not on 3G, while iPhone is actively transferring data over the cellular data network-downloading a webpage, for example-you may not be able to receive calls. Incoming calls may go to voicemail.
  

I hope , after this , you will be able to connect to Internet....

Thanks

Hello!
Here are the things you can try for a malfunctioing Wi-Fi on your Galaxy S:
Try turning off your Wi-Fi then turn it on again.

• Sometimes, this works for me as the Wi-Fi might need a restart so it can try scanning again. You can do so by going to Settings > Wireless and Network > Wi-Fi Settings and ticking the Wi-Fi checkbox.

Turn off your handset then turn it on again.

• An app that was running on your handset might be messing with your Wi-Fi, so to make all things better, you can restart your handset for a fresh boot. :)

Check if there are actually Wi-Fi networks in your area or the Wi-Fi is too weak.

• If there aren't any Wi-Fi networks to detect, it can't do anything at all in the first place. Try moving to an area with better Wi-Fi signal.

You can ask me if you have any queries! :) ~azukibean70

The password that my Iphone required was the 20 digit key located on the sticker as WPA-PSK. Hope this helps someone!

Try press ctrl+F2

Sorry, Sandisk 256mb + Wi-Fi SD Card is not compatible with e400. Only Sandisk Wi-Fi SD Card without additional memory is working.
