Hello, I am also having the same problem trying to swap from LG X Power to LG X Charge using the sim card from the LG X Power. I am unable to swap my device. Can someone help me? (apologies if this is hijacking the thread)
Hey there, Rinchan25! You must use the SIM card that was included with the new phone. If the issue persists after using the included SIM card, feel free to send us a private message so we may work directly with you.
