Nokia's "weak" portfolio, coupled with the company's discouraging financial reports, have raised serious concerns amongst international carriers. Operators are worried that the Finnish smartphone maker could file for bankruptcy or be sold by the end of next year.

Investment research firm, OTR Global, reveals that top carriers around the globe are losing faith in Nokia's power on the market. They no longer believe Nokia will remain a viable competitor in the global mobile marketplace.

The OTR study quotes four officials from the world's top carriers, yet did not disclose their identities. The report states, however, that all four carriers account for 54 million handset sales in the global mobile sector.

The executives also stated that they are not impressed with the latest Nokia smartphone, the Lumia 900. According to the report, the Finnish handset maker cannot put up a good fight against rivals like HTC.

The financial report revealed that Nokia lost $1 billion in the first quarter of this year. Last month, Moody's agency rated Nokia as nearly "junk" as a result of the company's steep decline.
