             CELLULAR TECHNICAL SERVICES REPORTS 2002 THIRD-QUARTER
                    RESULTS AND PROVIDES UPDATE ON OPERATIONS

Seattle, November 8, 2002 - Cellular Technical Services Company, Inc. (Nasdaq
SCM Symbol: CTSC) ("CTS"), a provider of products and services for the prepaid
and wireless communications industries, today reported its third quarter
financial results for 2002.

Total revenue decreased to $3.7 million in the three months ended September 30,
2002 compared to the prior year quarter, and to $9.4 million from $16.5 million
for the nine months ended September 30, 2002 compared to the prior year period.
2001 was the final year of revenue for CTS' Blackbird Platform product suite,
which accounted for $1.3 million in revenue in the third quarter of 2001 and
$4.1 million in revenue for the nine months ended September 30, 2001, compared
to zero in both 2002 periods. As previously reported, our Blackbird business
ended in December 2001 and we forecast no additional revenue from that segment
in future periods.

CTS reported a quarterly net loss of $783,000 compared to net income of $81,000
in the prior year period. The change is due to several factors: i) total gross
margin decreased by $1,116,000 as the Blackbird business provided $994,000 in
the prior year and decreased 2002 Isis gross margins of $122,000 due to volume
reductions and cost increases; ii) operating expense reductions of $290,000; and
iii) a combination of reduced other income, interest income and income taxes of
$38,000.

Revenue from the Company's Isis Telecommunications, Inc. subsidiary ("Isis")
decreased 8% to $3.7 million in revenue during the third quarter of 2002
compared to $4.1 million in the 2001 period, and 24% to $9.4 million in revenue
for the nine months ended September 30, 2002 compared to $16.5 million in the
2001 period. Today, with long-distance prices down substantially, customers need
to purchase fewer cards to get the same amount of calling time, impacting Isis'
revenue and profitability.

Since the Company's common stock traded below $1.00 for 30 consecutive trading
days, the Company received a notice from Nasdaq stating that it has 180 days
until April 30, 2003 to regain compliance by closing at least a minimum price of
$1.00 a share for 10 consecutive days to continue its listing on the Nasdaq SCM.
With approximately 2.29 million shares outstanding, the market capitalization at
a price of $1.00 is just under $2.3 million.

Stephen Katz, CTS Chairman and CEO, noted, "As of September 30, 2002 we had $4.0
million in cash, $4.1 million of working capital and no bank debt. We have made
the difficult decision to cease development

efforts of our Neumobility LBS platform and applications division. This is due to the uncertainty in both timing and magnitude of future revenue streams combined with the large continuing investment required to sustain, market and support the products. We have reduced our workforce by 13 personnel in the Neumobility division this week. We will, however, continue to seek outside partners or investors for the Neumobility IP portfolio and product suite. We are currently evaluating severance and any potential facilities or equipment related charges to be accrued in the fourth quarter related to the closure of this division. During the fourth quarter of 2002 we anticipate incurring approximately $0.1 million in cash severance charges and in the range of $0.1-$0.4 million in a combination of other charges related to the writedown of excess computer equipment and lease costs related to excess facilities to be paid through the third quarter of 2003. We forecast ending the year 2002 with approximately $3.2 million in cash. We believe that the business outlook is positive at TruePosition, Inc., an LBS company in which we have a substantial investment, especially given recent issues with competing technologies and TruePosition's strong intellectual property portfolio. Additionally, we are continuing to evaluate a variety of strategic alternatives with respect to our Isis prepaid products subsidiary and our other assets." The Company expects to schedule a conference call to discuss its results and operations to be held during the first week of December. SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS: This press release may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks and uncertainties that could cause actual results for CTS or its affiliates to differ materially from those expressed or implied in the applicable statements.
