              Telular Corporation Announces Second Quarter Results

VERNON HILLS, IL USA--Telular Corporation (Nasdaq: WRLS)

--------------------------------------------------------------------------------

Telular  Corporation  reported  revenue of $13.8 million for its second  quarter
ended March 31, 2003.  Compared to the same period last year,  revenue  declined
$5.4 million from $19.2 million.  The Company reported a second-quarter net loss
of $1.2 million, or $0.09 per share, compared to net income of $211 thousand, or
$0.02 per share, for the same period last year.

"Fewer shipments to Mexico and generally poor worldwide  economic,  industry and
political  conditions resulted in lower shipments for the quarter," said Kenneth
E. Millard, Chairman and Chief Executive Officer.

For the first six months of its fiscal year 2003, the Company  reported  revenue
of $39.5 million,  compared to $26.4 million last year for the same period.  The
Company  reported  net  income  of $1.1  million,  or $0.09  per  share  for the
six-month  period,  compared to a net loss of $2.6 million,  or $0.20 per share,
for the same period last year.

Operating Details

Fixed  Wireless  sales of $10.7 million  decreased 34% during the second quarter
from the same period last year,  while Wireless  Alarm revenues  increased 5% to
$3.1 million over the same period last year.

"While  revenue  from Latin  America  fell 45% in the second  quarter due to the
lower shipments to Mexico, the decline was partially offset by strong results in
the USA where  Phonecell(R)  Fixed Wireless sales increased 50% over last year,"
added Millard.

On a fiscal  year-to-date basis, Fixed Wireless sales of $33.2 million increased
62%, or $12.7 million, compared to the same period last year. On the same basis,
Wireless Alarm  revenues  increased 7% to $6.3 million over the same period last
year.

The Company's  gross margin was  unchanged  from last year at 29% for the second
quarter.  On a fiscal  year-to-date  basis,  gross margin of 29%  represents  an
improvement of 2 percentage points over the first half of fiscal year 2002.

Operating  expenses for the second quarter  declined 6 percent from last year as
sales  and  marketing  expenses  declined  13% due to lower  sales  volume,  G&A
expenses declined 12% and

engineering and development expenses increased 10%. The increase in engineering
expense resulted from substantial investments in CDMA2000(R) 1XRTT products.

"The demand for CDMA Wireless  Local Loop products has become  stronger with the
rollout of 1XRTT networks in key markets,  including China, India, Venezuela and
the USA,  added  Millard.  Our recent  investment in a CDMA  technology  license
improves our position to provide cost effective,  feature rich products for this
rapidly growing market."

On a fiscal year-to-date basis, operating expenses increased 2 percent over last
year.

During the second quarter, the Company used $7.4 million of cash for operations,
compared to  generating  $250 thousand of cash from  operations  during the same
period of last  year.  Through  the first six months of fiscal  year  2003,  the
Company used $1.5 million of cash for operations  compared to using $5.6 million
in operations during the same period of last year.

"Over $6.8  million of the cash used for  operations  during the second  quarter
related to unfavorable  changes in working capital,  including $4.2 million used
to decrease accounts payable," said Millard.
