"Invalid SIM" When Service Transfer from Global SIM to LTE SIM
I ordered a 4G LTE SIM by clicking "Click here to upgrade" link in my original Global SIM account. After receiving the SIM, I tried to transfer the existing service from Global SIM to LTE SIM by clicking "I ALREADY RECEIVED NEW SIM (UPGRADE NOW)" button in my Global SIM account. I was then prompted to input the new SIM's ICCID number on "Service Transfer" page. However, after inputting the ICCID of my new SIM and clicking "VALIDATE" button, I always got "INVALID SIM" error message on the screen. The Tier 1 support doesn't know the answer after I issued a ticket. There has been no further help from FP after the issue was "escalated to our higher level of support for further review" several days ago. Can any one on this forum help me to resolve the issue? THANKS
