SGH A 707 SIM card problem

3 July 2008
My Samsung SGH A 707 was wonderful UNTIL I went to Thailand where I was advised to buy a SIM card there as I was told my American phone would not work. I bought the Thai SIM card and my phone stopped working. I took out the Thai SIM card and replaced it with my American card which just shows this message on the screen: “Phone freeze SIM unavialbel. Please contact service provider”.
We contacted Samsung and they were useless and rude. We contacted Cingular they could not provide any useful information. My computer engineer friend in Thailand said we needed a password but Cingular seemed pretty clueless.
Can anyone help? This just does not seem that complicated!
Thanks for any advice.

At this stage, call AT&T is probably the best bet. Call back until you get a more knowledgable technical support rep.

Can I move text messages from my phone's internal memory to a memory card on a Samsung A-707?


Transfer to SIM car memory first. Use PC software to copy SIM card contents on harddrive. Use software with Samsung to copy the contents on hard drive onto your new mobile phone

I have a Samsung 707 Sync and when I try to view my text messages all I get is a blank white screen.


I had the same exact issue.  Also, I couldn't send, receive or view old messages.
What I had to do was power it up without the SIM card.  You should get a message that there is no SIM card - that's ok.  Then power it down, re-install the SIM card and power back up.  My problem went away.

Samsung SGH a-707 has password that I don't know. I do I get past this?


Having a similar problem...i went into the store and they tried replacing my sim card but since my kid put the password and then forgot it, the sim card solution did not help. You might try going into a cingular store and let them try to unlock it. Seems there are a few tricks to be tried, but i am calling samsung for help.

Unlock Samsung SGH A 707.


Try these guys.

I gave them my IMEI number and they sent me a password. If you insert a non-AT&T SIM Card then turn on the phone, type in the password and you should be unlocked.
