There were a few groups iirc - including GSM, CDMA, & NTT's standard.
Instead of deciding on 1 specific standard, they worked out how to make

Does anybody have an idea about, which part of 3GPP specification
covers about the access classes(0-9 standard ones and also 10-15
special ones) and the subscriber categories that are covered under
these classes?

Can anyone please kindly explain me what is called frequency hopping in
GSM.
Thank you
With warm regards,

I picked up a new Virgin Mobile SIM(pay-as-u-go) on ebay,,
Put it in my T68i and it linked to t-mobile (the USA roaming agent)..
Went to the www.virgin.com/modile site and after some very slow servers,, was able to get

I purchased a Riiing SIM from a German company off Ebay May 9th for a
trip I'm taking tomorrow (the 22nd) to Europe.  Bad Move.  They shipped
it the 10th airmail, but it evidently got lost.  I should have bought it
from Telestial here in the US, but thought I'd save some bucks.  ...

I just got a Nokia 3620 for Cingular.  I was unable to make certain changes
because the phone is locked with a PIN code.  I was able to UNLOCK the
phone, but it still requests a PIN code to make changes.  Argh!  Is there a
way to reset the phone? or do I need to get that from ...

Is it possible to remotely unlock a Siemens MC60 for less than 35 UKP /

Normally, if going abroad for a reasonable period, I get a local pre-pay SIM
as it normally works out a lot cheaper, mainly because of no charge for
incoming. (Eg Ireland, Australia New Zealand) or use a United Telecom SIM.
I'm going to Canada (Alberta/BC) and Washington State ...

Is anyone here aware of a GSM modem (dual-band will do) with a USB
interface - preferably powered via the USB ?
I've googled a bit, but the number of hits on "USB GSM MODEM" is quite
overwhelming.

Is EDGE just used for faster data transfer rates for data calls and
web browsing?  Or is it also used for voice calls?  Will it be a
problem in the future if your phone doesn't support EDGE and your
network begins to use it?

Hi, I was planning on getting a new t-mobile phone with a service plan
through Amazon and cancelling my existing t-mobile line.  However,
Amazon has a statement on their rebate that voids the rebate if a new
customer cancels an existing t-mobile line before or after the new
