Possible Problems/ Solutions
Please wait for 1~2 minutes after the router is
turned on.
If RSSI is blinking, you have no good RF
reception. Change the location of the router.
Make sure your (U)SIM card is inserted cor-
rectly and the PIN number has been entered.
If the PIN number has been entered incor-
rectly then you will need to enter the PUK
code when prompted.
Remove any electrical appliance which is too
close to the phone or router.
The cable or phone set might be faulty.
Put the phone on hook and try again. If you
are connected to the internet using the 2G
(GSM) network, please disconnect this first.
When you have finished dialing you can press
the # key or wait 4-8 seconds to connect the
call.
If you are connected using the 2G (GSM) net-
work then you cannot surf the net and make
a phone call simultaneously. Please discon-
nect the internet and wait 30 seconds to 1
minute before making a call.
