Message: Phone Freeze SIM unavailable please contact service provider

I have been given two old Samsung flip phones: A411 and C5220 which are all Telstra prepaid phones. No SIM or documentation. When inserting my BOOST SIM card which is operated on the Telstra network the phones work fine. I want to use a SIM from a different provider but the phones come up with:

Phone Freeze SIM unavailable please contact service provider.

I tried this new SIM in another phone and it is activated and works fine.

I checked on both old phones with *#7465625# and only the network lock is ON, all other locks are OFF and as I mentioned before, the phones work fine with a Telstra network SIM.

I rang Telstra and they kindly supplied me with the network unlock key for both phones based on the phone's IMEI numbers. Yet, I could not enter this code and the phones come up with the Phone Freeze message. As soon as I put the Telstra network SIM in again the phones work okay.

I rang Telstra back again and they said that I will have to contact SAMSUNG since the phone freeze is due to too many wrong tries to enter the unlock code and I will need to get an 'unfreeze key' (MCK?) before I can try to enter the Telstra network unlock key.

Did contact SAMSUNG on live chat and they ask me to do a master reset with *2767*3855# . It is still 'Phone freeze' for the non telstra sim but works again with my BOOST sim! I told them that I don't think the phone is not working but might need some other code.

They answered: 'I do get your point there, however for us to remove the phone freeze we would need to have the technicians look unto the mobile phone since even the Master Reset did not fix the issue'. I contacted the recommended local Samsung repairer but unfortunately they are asking for quite a lot 'just to have a look'.

Can someone please help to save these phones from the recycling bin?

Hello,

Either the new sim card made the phone to go in freeze mode, or somebody else tried to unlock them with a wrong code before. Now beside the network unlock code you will need a code to get the phone out of freeze mode. Can i have the IMEI (you will find it on the back of the phone underneath the battery or in menu if you type *#06# ) of the phone maybe i can help you with the unlock codes.

Hi Alex

Tried to post the IMEI numbers but always get message

'422 marked as spam - Your content was marked as spam by our automated moderation system.' Any other way of getting the details to you?

Hi Alex

I will give it another go:

Here are the two IMEI numbers.

(357027/01/221364/3) for the Samsung A411

(358724/02/550617/4) for the Samsung C5220

Hope this helps.

Sorry for the late answer. I will try tonight to get the codes for them and send them your way.

If Alex cannot provide the MCK, the unfreeze codes can also be purchased from Ebay.

Hi Alex

Sorry to bother you again. Just checking if you are still trying to get the codes for me? I had a quick look at ebay but find it rather confusing. Hope you can help. Happy to wait .

I have spoken to Samsung, Telstra & Amaysim but no one can help me & they all just pass the buck!

You likely will need to buy an unlock code from Ebay.

i did unlock it via Telstra, that went through fine, but then this other message came up.

Hi dusk2dawn

Have you had any luck with the code from Ebay? I found it too confusing and gave up. Will be interested to hear your experience.

Hi Joe.

I haven't tried the code on Ebay, I did not want to pay out more money not to have it work. I was not sure what code to ask for either as I have already unlocked it via Tesltra. Maybe you could post the instructions & I'll have a look at it?

por

Hi dusk2dawn

Same here. Not sure what exactly I need or what the process is so did not take it any further. Maybe Alex could get back in touch and clarify please?
