mobile telephone FAQs

How do I get the best performance from GPS?

It is recommended that AGPS is used to speed up the connection time for GPS. AGPS uses the Mobile Internet connection to connect to a GPS server that tells the device which GPS satellites it will be able to connect to, substantially reducing the time taken to get a GPS fix. When a device is used with integrated GPS receiver, look into the manual of the device for the location of the GPS receiver. When using the GPS receiver, hold it upright in the hand at an angle of approximately 45 degrees, with a clear view of the sky. Make sure that the hand does not cover the GPS receiver. The time it takes to establish a GPS connection may vary between a few seconds and several minutes. Establishing a GPS connection in the car may take longer.

Note: The GPS operations take their power from the battery. Using an internal GPS receiver or a Bluetooth connection to an external GPS receiver may drain the battery faster.

If no satellite signal is found, consider the following:

• Check that the hand is not covering the GPS receiver.

• If indoors, go out doors to receive a better signal.

• If outdoors, move to a more open space.

• If the weather conditions are bad, the signal strength may also be affected.

What are PIN codes, PUK codes, lock code and restriction code?

PIN (Personal Identification Number) codes:

The PIN code protects the SIM card against unauthorized use. It is asked for when the SIM card is inserted and the device boots up for the first time. The PIN code is 4 to 8 digits long and usually supplied with the SIM card. However, it is recommended to change the original PIN code to a unique number - the instruction on how to change the PIN code is provided in the user guide.

UPIN code is usually supplied with the USIM card. The USIM card is an enhanced version of the SIM card and is supported by UMTS mobile phones.

PIN2 code is also 4 to 8 digits long and is supplied with some SIM cards, and is required to access certain services. If any of the above PIN codes are entered incorrectly three consecutive times, you will need corresponding PUK codes to unlock them. Read more about PUK codes below.

PUK (Personal Unblocking Key) codes:

• PUK code is 8 digits long and is required to change a blocked PIN code.

• UPUK code is required to change a blocked UPIN code.

• PUK2 code is required to change a blocked PIN2 code.

• The PUK codes are provided by Armstrong Bell.

Lock code / Security code:

• The lock (security) code protects the device from unauthorised use.

• The default code supplied with the device is 12345. However, it is recommended to change the default code to the users own. The instruction on how to change the security code is provided in the user guide provided with the device.

• Keep the new code in a safe place separate from the device.

Other PIN codes:

• The module PIN is required to access the information in the security module of the SIM card.

• The signing PIN may be required for the digital signature.

Are Mobile Phones Safe to Use?  What about Radiation Levels?

Comprehensive research on Electro Magnetic Field (EMFs) issues has been carried out over several decades. Based on these studies, it has been shown that mobile phones that conform to international exposure standards do not cause any adverse health effects.

Why Does Signal Strength Vary Between Different Phones?

The number of bars displayed on different phones may vary due to the algorithm used to convert incoming radio signals into displayed signal strength, a formula that varies from manufacturer to manufacturer. For this reason, two phones set side by side may display different levels of signal strength.

Activating Voice Mail, Call Forwarding, PIN code, and Call Waiting?

• To divert calls when on another call dial **67* phone number where calls are to be forwarded # followed by SEND

• To divert calls when there is no reply dial **61* phone number where calls are to be forwarded # followed by SEND

• To cancel all diverts set dial ##002# followed by SEND

• To check the diverts you have set dial *#21 (ALL) or 67 (BUSY) or 61 (UNANSWERED) or 62# followed by SEND

• To set divert to 901 dial 1750 followed by SEND

• To cancel divert to 901 dial 1760 followed by SEND

•To set the number of rings before divert dial **61* voicemail box number *10* amount of seconds # followed by SEND-default 901 voicemail box number is +447802091901
