Some of the accessories mentioned in this user
guide, such as charger, headset, or data cable, may
be sold separately.
Avoid touching the antenna area while the antenna

communication quality and may reduce battery life
due to higher power level during operation.
Get started
Before you start using your phone, remove the back
cover and battery to insert the micro-SIM cards (also
known as mini-UICC cards).
Remove the back cover and battery
Make sure the phone is switched off.
1. At the bottom corner of the phone, put your
thumb in the seam between the screen frame and
the back cover. Do not use any sharp tools, as they
may damage the phone.
2. Bend the cover open, and remove it.
3. Lift the battery out.
Insert the SIM and memory card
1. Slide the micro-SIM card into the SIM slot with the
metal contact area down.
2. For RM-1090: If you have a second SIM card, push
it into the SIM2 slot until it locks into place.
3. If you have a memory card, slide the card into the
memory card slot.
It is recommended that you use a fast microSD card
from a well-known manufacturer.
Use of incompatible SIM cards, or use of SIM card
adapters, may damage the card or the device, and
may corrupt data stored on the card.
Replace the battery and back cover
1. Line up the battery contacts, and put the battery
in.
2. Press the top edge of the back cover against the
top edge of your phone, and snap the cover into
place.
3. To switch your phone on, press and hold the
power key.
