FAQ
Most common
application:
You own an existing handheld
phone and are seeking a bag phone for 5 times the transmitting power at
no additional monthly costs.
How does it work?
When a phone call is made, your cell phone's software sends a
unique signature or address identifying your phone to the network. Our
equipment will program this unique signature into your new extension and
the network will now recognize the second signature as your original.
Calls can be made and received on either phone. However, only
one phone may be on at one time. If both phones are powered
on, they will each try to register with the network. The network can
only recognize one address and location per phone number. For this
reason, we stress that only one phone can be on.
Can I only have 1 extension?
No. You can have as many extensions off of the original as
wanted. However, same rule applies, only one phone on at one
time.
How do I tell if I have a GSM phone?
Pop off the battery or back cover. Near the bottom of your
phone, if you have a small plastic wafer card clipped in to place, you
have a SIM card inserted. If you have a SIM card, this means its a GSM
phone. An extension cannot be programmed to your
phone.
Can I call the extension phone from
my primary phone?
No. Much like your household phone, you can't call from your
kitchen to your bedroom!
Can I use an analog extension with
digital service?
Yes if your digital service provider also supports an analog
system. If your current handheld is a Tri-mode and can receive analog
service, then definitely no problem. You may have to check with your
provider for this. Motorola bag phones operate on a 800 Mhz AMPS Analog
system.
Does the extension phone have to be
the same make as the primary?
No, they can be different makes and models. Any cell phone
can have an extension.
Where do I find the ESN (electronic
serial number)?
The ESN number is either an 8 digit Hex-Decimal Number or 11
digit decimal number. Look on the back of your cell phone, usually
underneath the battery. It may also be listed as an MSN # (manufacturer
serial number) if it doesn't list any other numbers. It will be the
first 8 numbers of the MSN. Many new handheld phones will list the ESN
in the Option Menu's on your display screen. Or look on your original
service contract. Call your service provider?
Where do I find the SID (system ID)
number ?
It is a one to five digit number. (example: 00031) Call your
service provider, just tell them that you need this number for your own
personal records. Another option is to put your primary phone into NAM
programming mode (look in your manual for direction), and read it from
there.
What if I can't find any of these
numbers? Can I still get an extension?
Yes. However you will need to include your primary phone with
your order, so the programmer can download the required info directly
from it.
What if I change cellular providers after
I have an extension programmed to my primary phone?
Once the extension(s) is programmed to the primary phone, the
extension will follow the new service. However you will need to
program the new telephone number and SID number for the new carrier.
