Unlocked Samsung SGH-U600 - how do I? (settings for MMS)

I have an unlocked (UK registered) Samsung SGH-U600 which I use with my existing provider - Cingular/AT&T. However, because they don't carry the phone, they won't help me with the settings so I can send for example txt msgs w/attachments (pics)...even though my rate plan allows it. I think I figured out the Browser settings but I can't get the MMS and Email settings right so I can send. Can you help?

They have the settings, most likely, even though they don't carry the phone.  I have ran into this before.  Ask to talk to Tier 2 Technical Support.  Tell them that samsung told you they would have the settings.  They'll do it but it takes a while bc you have to manually enter the settings and passwords.  And always ask them if what they are telling you to put in is in CAPITALS or lower case, it does matter.

If you are trying to use a SIM card in your phone and getting a message like "Enter Subsidy Code", "Incorrect SIM Card", "SIM not provisioned" or similar messages, then you need an unlock code for your mobile phone. You can get Samsung SGH-U600 Unlock Code from the network provider, they will provide an accurate code with easy to follow instructions on how to unlock your phone. You may check Samsung Unlock Code site, they can open up all networks for you where you want to use your phone. Once your phone is unlocked, it will work with any networks worldwide.

Hope this is helpful.

Cant get picture messages on my samsung u600 on virgin can anyone help

Hi the problem you are having is with the mms settings, all you need to do is contact your service provider and ask them to send you the latest mms and wap settings, they will send you these for free via text message and this will then update your phone to the correct settings.

they dont charge for this service so give them a call

Can it receive and send pictures?

Yes it can send and receive pictures, you just need to set up the MMS features of this and you need that from your service provider to activate it so you will be able to send and receive pictures....

I bought UK unlocked Samsung SGH U 600 T Mobile

T-Mobile USA and T-Mobile UK use different WAP and MMS settings - you will probably discover that t-zones doesn't work on the phone either.

The simplest thing to do is go to the T-Mobile USA site and use the OTA configurator to send the correct settings for WAP and MMS to your phone.

Cant send or recieve mms messages

Is your internet and text messageing for incomming and outgoing working? If it is you will need to contact your carrier and let them know...they will collect some information from you and send it off to thier engineers to have your issue might be something as simple as you need the correct feature or settings on your account adjusted. Also if it's unlocked...there's no guarantee that the internet will work on another carriers network therefore it limits what other features you can use...such as mms (which is one part internet and one part text message). Good luck

Samsung U600 mms

I had this problem and just fixed it via my Orange mobile website. Find the area for Multimedia messaging problems. Key in your phone number on your support page and they give you a pin number. They then send you installation instructions to your mobile. Key in the PIN and follow the instructions. Works fine now. Your provider's help pages will hopefully use this same method?
