Dual micro SIM cards
HTC Desire 501 has two micro SIM slots.
Slot 1 supports WCDMA and GSM. Slot 2 supports GSM.
Inserting the SIM cards
Use a standard micro SIM only. Inserting a smaller size SIM (such as a nano SIM with
an adapter or a modified SIM) may cause the card to not fit properly or damage the
card slot.
1. Take the back cover off.
2. Insert a SIM card into either SIM slot as shown. If you have another SIM card,
insert it into the other slot.
When inserting, make sure the gold contacts on the SIM card are facing down.
