I've tried all of the providers listed above. Unfortunately, none of them we're able to provide me with a code. Has anybody had any luck in finding a provider to unlock their Lumia 640 from Cricket?
No dice- doesn't look like there's any way to unlock this (short of paying for months of Cricket service).
I was finally successful and was able to get my Cricket Lumia 640 unlocked using AT&T Unlock Code - AT&T IMEI Unlock Code - AT&T SIM Unlock Code.
@westnz thanks for the update. Ya I was given a similar update stating that may be in 3~6 months I could expect the code. I was also told that you need to activate and use it on Cricket for best chances and even post that there is no guarantee. So in no hurry so will wait! Till then will use it for other functions![]()
