*****Make SIM/eSIM available**** 
Follow these steps if you need to skip the normal "aging" wait time and make the SIM/eSIM immediately available.

From the Profile toolbar, click the Tools tab, then select SIM/eSIM Status.
Enter the 19-digit ICCID or 32-digit EID and click the Search icon.
Choose the Actions drop down and select Change to available.

Sending a one-time QR code
Most eSIM devices should use the On Device eSIM Activation process, this process should be used for troubleshooting.

**Important** Device Profile status must be Released and SIM status must be Assigned In Use in order to send a QR Code (or see the Actions button in some scenarios).

Open the SIM/eSIM Support Tool in Atlas Troubleshooting, Rebellion Troubleshooting, or Tapestry.
Enter the 32-digit EID or 19-digit IMEI and click the Search icon.
Click Actions, then select Generate/Send QR Code.
If the option to send a QR code is not available in the SIM/eSIM Support Tool, confirm that the device Profile status is Released and the SIM status is Assigned In Use.
Enter the customer's email address, then click Send.
You must enter the customer's email in all lowercase. Using uppercase letters will result in an error message regarding an invalid email address. 
If the error “There was a problem sending the QR code. Please try again.” appears, the email address entered was invalid and needs to be reconfirmed. 
Instruct the customer to follow the device specific steps to scan and download their eSIM profile. 

Reset Allocation
Only follow these steps when directed by troubleshooting. Follow these steps to reset the network counter on an eSIM wearable. This is required when an eSIM device has requested too many profiles, such as when Apple Watches show error 406 when downloading their eSIM.
Note: Reset Allocation does not work on eSIM smartphones. 

Go to the ESIM profile on the Device tab.
Under Actions, select reset allocation.
 

Known issues for SIM/eSIM Status
Some SIMs released using the SIM/eSIM Support Tool can't be used right away. This is due to a timing issue with a backend database that houses SIM status.
SIMs attached to canceled MSISDNs can't be released by the SIM/eSIM Support Tool. Follow SIM reuse to check eligibility and file SIM/MSISDN Reuse forms.
SIMs attached to MSISDNs that have been cancelled or suspended by RAT cannot be reused.
eSIMs activated on Prepaid, Metro, or Wholesale accounts will display a random MSISDN in Grand Central and “N/A” in the MSISDN field in the Atlas and Rebellion SIM/eSIM Support Tools. Atlas and Rebellion will return the correct Brand ID, which can be used with the ICCID, IMEI, EID to look up the MSISDN in billing. Fix is TBD.
Do not file SIM/MSISDN forms or contact NTC Resolution Team to request one of these SIMs be reused.
IMPI error workaround
If you encounter an IMPI Error when attempting to use a SIM after changing the SIM Status to Available in SIM/eSIM Support Tool, complete the SIM/MSISDN Reuse form.
Include in the comments that an IMPI error was received.
If the situation requires an escalation, have your coach/senior email the SIM/MSISDN escalation team to work on resolving the IMPI Error.
Include the SIM/MSISDN Reuse form number in the email.
The SIM/MSISDN Escalation team will attempt to resolve the issue, but may need to submit a help desk to for resolution.
Once the issue is resolved, they will reach out to the customer to complete their request.
