FOR RELEASE: IMMEDIATE

                         AMERICAN PORTABLE TELECOM FILES
                           FOR INITIAL PUBLIC OFFERING

February  20,  1996,  Chicago,   Illinois  -Telephone  and  Data  Systems,  Inc.
[AMEX:TDS] announced that its subsidiary, American Portable Telecom, Inc. ("APT"
or the "Company") has filed a registration  statement  today with the Securities
and  Exchange  Commission  covering an initial  public  offering of 11.0 million
Common  Shares,  all of which will be issued and sold by APT.  The Company  will
also grant to the  underwriters  an  over-allotment  option for up to  1,650,000
additional  Common Shares.  Upon completion of the offering,  TDS will own 84.3%
(82.4% if the  over-allotment  option is exercised) of the capital stock of APT.
It is estimated  that the initial  public  offering price will be between $15.00
and $18.00 per Common Share.

A  portion  of  the  net  proceeds  of  the  offering  will  be  used  to  repay
approximately  $60.2 million of outstanding  indebtedness to TDS. APT expects to
use the  balance  of the net  proceeds  of the  offering  to  partially  finance
construction,  development and operating costs associated with the establishment
of  personal  communications  services  ("PCS")  networks  in  the  Minneapolis,
Tampa-St.  Petersburg-Orlando,  Houston,  Pittsburgh,  Kansas City and  Columbus
Major Trading Areas ("MTAs").

The  offering  will be  managed  by  Donaldson,  Lufkin  &  Jenrette  Securities
Corporation, Merrill Lynch & Co., and Salomon Brothers Inc.

American  Portable  Telecom is the  fifth-largest  licensee of PCS in the United
States in terms of  population  equivalents  ("POPs"),  with licenses to provide
service in six MTAs in the United States  including  approximately  27.3 million
POPs.  The Company plans to construct  networks for its PCS markets using Global
System for Mobile  Communications  ("GSM")  technology.  The Company  intends to
commence  marketing  efforts  and  launch  commercial  service in early 1997 and
expects to complete initial construction of its PCS networks by the end of 1998.

A registration  statement  relating to these  securities has been filed with the
Securities  and  Exchange  Commission  but has not yet become  effective.  These
securities  may not be sold nor may offers to buy be accepted  prior to the time
the registration statement becomes effective. This shall not constitute an offer
to sell or the  solicitation  of an offer to buy nor shall  there be any sale of
these securities in any State in which such offer, solicitation or sale would be
unlawful prior to registration or qualification under the securities laws of any
such State.

TDS is a  Chicago-based  telecommunications  company with  established  cellular
telephone,  local  telephone  and radio paging  operations  and  developing  PCS
operations.  TDS  strives  to build  value  for its  shareholders  by  providing
excellent communications services in attractive, closely related segments of the
telecommunications industry.
