CREATION OF NEW TOWERS COMPANY IN DRC

CREATION OF NEW TOWERS COMPANY IN DRC

New York and Stockholm, 22 December 2010 - Millicom International
Cellular S.A. (“Millicom”) (Nasdaq Stock Market: MICC and
Stockholmsbörsen: MIC) today announces that its subsidiary in the
Democratic Republic of the Congo (”DRC”), Oasis (“Tigo DRC”) has agreed
to sell 729 towers to Helios Towers DRC (“HTD”), a direct subsidiary of
Helios Towers Africa (“HTA”).  As a result of the transaction, Tigo DRC
will receive at least $45 million of cash up front and will retain a
significant minority interest in HTD.

Additionally, Tigo DRC and HTD have entered into a long term leasing
agreement whereby HTD will provide Tigo DRC with access to wireless
communications towers and a build-to-suit agreement to support the
company's wireless networks.  HTD will seek similar agreements with
other operators in DRC.  The transaction is expected to create savings
in both capital and operating expenditure for Tigo DRC.

Mikael Grahne, President and CEO of Millicom, said:

“This agreement with HTD in DRC is Millicom's third such deal with
Helios in Africa and it brings us to a point where nearly two-thirds of
our towers in Africa are committed to be outsourced. We view the DRC as
a very attractive market for asset sharing considering its size, lower
average purchasing power and logistical complexities. We are confident
that this and similar previously announced ventures will continue to
produce satisfactory results and improved service levels as we have
experienced in Ghana since the creation of the first tower joint venture
in Africa with Helios in January 2010. These agreements, and any future
sale of our remaining towers in Africa, will enable us to improve both
our capital and operating efficiency by focusing on our core activities
of sales, marketing, branding, distribution, service innovation and
customer care.”

Charles Green, CEO of HTA, said:

“With this latest transaction with Millicom in DRC, HTA is firmly
established as the leading independent tower company in Africa. Under
increasingly competitive conditions in many African markets, HTA enables
wireless operators to outsource non-core tower-related activities and
focus capital and management resources on providing higher quality
services more cost-effectively. We continue to be enthusiastic about
extending to Tigo DRC our successful partnership formed in the landmark
transaction completed earlier this year with Tigo Ghana and more
recently in executing the agreement to acquire Millicom's tower assets
in Tanzania. As with the other transactions, we are pleased to enter
into such an innovative arrangement with Millicom, which ensures that
HTD has, as an anchor tenant on each of its towers, a high quality
operator with a demonstrated long-term commitment to the development of
wireless services in DRC."

The specific number of towers and final purchase price will be
determined at closing. First closing of the transaction, subject to
customary closing conditions, is expected to take place around Q3 2011.
