Operation Manual

The phone is hot
When you use apps that require more power or when you use apps for an extended period of time, the
phone may feel hot to the touch. This is normal and should not affect the phone’s life span or performance.
I cannot make or receive calls
• Reception may be poor in the current location. Move to another area and try again.

which are preventing the phone from making/receiving calls.

The SIM card is locked
If you have enabled the SIM lock feature, the SIM card must be unlocked each time your phone is turned
on.
If the unlock code is entered incorrectly 3 times, it becomes PUK-locked and can only be unlocked with
the operator-provided PUK (Personal Unblocking Key). Contact your mobile network operator for more
information.
The SIM card is PUK-locked
Once the SIM card is PUK-locked, it can only be unlocked with the operator-provided PUK (Personal
Unblocking Key). If the PUK is entered incorrectly 10 times, the SIM card can no longer be used and you
must replace the SIM card. Contact your mobile network operator for more information.
