Mom went abroad and had to change sim-card, now back she can't unlock her sim. For some reason she had 2 cards, none of them worked with the pin and puk I got from the contract. It has been going on for 2 days and I lashed out at her, because I'm across the country, don't blame me for it not working.
15 minutes later she started to giggle.
Turns out she had a third sim card. The right one.
