Samsung SGH-A707 - Phone Freeze, sim unavailable (at&T)

Hello i own a Samsung SGH-A707 Cellular Phone, which was purchased several months ago in Florida, USA, by a family member who was there for a business trip.

I leave in Papua New Guinea (PNG), which is in the South Pacific, north of Australia.

The phone was working fine, when it was being used in the States, however, when brought back to PNG it wouldn't accept our sim, it was locked as well.

I did searchs on the internet and found some solutions however using those solutions led to my phone being frozen with the above error message 'Phone Freeze SIM unavailable Please contact service provider'

Because of my unique location, i'm having difficulty contacting service provider at&t.

Can you please help me.

Teri - PNG Samsung SGH-A707 Cellular Phone user.

Your best bet would be to take it to a local mobile store to unfreeze it. You should've got it unlocked while in the US by calling AT&T and you could have done it for free. Sorry.

My phone says: phone freeze, sim unavailable model samsung A707

OKAY, Ignore the posters saying that you need to buy a 'freeze code', the truth is you don't. If your phone has 'phone freeze. sim unavailiable' please enter in *2767*3655#. After you do so the phone will restart and will work with your sim inserted. I hope this solves your problem.

Kind Regards,

Phone freeze sim unavailable contact service provider

I had a similar problem a few months ago. A friend of mine suggested that I turn off my phone, take the battery out and then the sim card out (the little card that says either CINGULAR or AT&T) on the back. Blow some air to try and get the dust out and put everything back on, then turn on the phone again.

It worked!!

I don't know if this will work for you, but I hope it does!! Good luck!!
