LG U+ informs customers by text message when the usage period expires or the top-up balance runs out, and never calls separately about period extensions or voice top-ups. LG U+ also never asks customers for personal information, so please be careful to avoid any related scams.

You will receive a full refund as long as you have not used the voucher after booking. However, refunds are not possible once the SIM card has been collected (refunds are not possible if the SIM card shows scratches or other damage after opening).
