Tuesday, the shares of Telefonica's O2-branded German unit saw an increase by 3%, as per a recent report. The rise was seen probably in the wake of a biggest initial public offering by Europe in more than a year.

U. S. telecommunications giant AT&T Inc. enjoyed the best profitability ever in its wireless arm in the second quarter, even as it suffered a considerable decline in its smartphone sales.

AT&T revealed on Tuesday that it activated 5.1 million smartphones in its most recent quarter. The figure is down from 5.5 million in the corresponding period of 2011.

US wireless carrier Verizon has announced plans replace almost all of its existing phone schemes with new pricing plans that will encourage customers to connect their non-phone devices, such as tablets and PCs, to the company’s network.

The new plans allow subscribers and their families to share a monthly data allowance over a maximum of ten devices. The new approach reflects the carrier’s intention to continue growing as nearly every citizen in the country already owns a phone.

According to the Wall Street Journal (WSJ)’s late Monday report, with AT&T’s proposed $39 billion acquisition of T-Mobile having fallen through, the two companies have recently filed for the US Federal Communications Commission (FCC)’s approval for the transfer of $1 billion in wireless airwaves from AT&T to T-Mobile.

After lobbying intensely for months for its proposed $39billion takeover of its smaller US rival T-Mobile, AT&T announced on Monday that it has decided to scrap the T-Mobile merger deal because it was unsuccessful in overcoming stiff competition from the government.

The scrapping of the deal means that, in accordance with the terms of the March-announced merger, AT&T will pay T-Mobile's parent Deutsche Telekom $4 billion in cash and wireless spectrum access as a break-up charge.

In a fear that Deutsche Telekom would run out of supply, they have started advance booking for Apple’s iPhone 5 in Germany.

On Thursday, the Deutsche Telekom (DTEGn. DE) has claimed that it is on the way to achieve its 2011 targets, in spite of poor performance in the United States, economic weakness in southeastern Europe as well as sluggish growth in Germany.

Its Chief Executive Rene Obermann has expressed immense confidence that Company would achieve its targets soon and said that the second quarter results cannot be considered as a reason for celebrations. The Company has claimed improving business at its European operations.
