I have the same issue. Sprint is telling me that the phone is unlocked but I when I insert a Cricket SIM, I get an Invalid SIM error.
In the UICC setting.... I have a msg that says "Your Device is locked to Sprint SIMs only"
I have called Sprint cust Support 4 times.
Can anyone help?
if it is no longer on a active line make sure that the Sprint sim card is still in it, that its turned on and connected to wifi with any power saving settings turned off so it doesnt disconnect you from wifi at any point..make sure this is done prior to an agent contacting you so there are less chances of the phone not receiving the unlock code.
Thanks, all your recommendations are in use. I'm on the phone with Sprint.
Let's see If we are successful....
Let me know if you need help further.
Alright let me take a look.
Has your phone been on wifi with the original SIM in it? If so, then did you try resetting your phone? With the Sprint SIM in it you can press ## BRAND # and your phone will restart. Once it comes back up press ## SCRTN # and this will restart your network.
So happy to hear you issue has been resolved @Renefcruz. We are always here to help.
I'm having a similar problem:
1.) I brought an unlocked ATT iphone 6s to a Sprint BYOD plan and bought an insurance plan from Asurion.
2.) After some connectivity problems, Asurion had me send them the original unlocked iPhone above and they replaced it with a refurbished iPhone 6s.
3.) Now i find out that the replacement iPhone from Asurion is locked to Sprint. Sprint customer service put in an unlock ticket for me, but I received an email saying the iPhone could not be unlocked because it came from another carrier.
Can you help straighten this out.
