Jan 27 (Reuters) - Sprint Corp said on Monday it lost fewer than expected mobile phone subscribers who pay a monthly bill in the third quarter, benefiting from cheaper plans ahead of a merger with larger rival T-Mobile US.
The company said it lost 115,000 postpaid phone subscribers during the quarter ended Dec 31. Analysts were expecting a net loss of 160,000 subscribers, according to research firm FactSet.

Net loss attributable to the company fell to $120 million in the quarter ended Dec. 31 from $141 million a year earlier.
On a per share basis, the company reported a loss of 3 cents per share, unchanged from a year earlier.
Total net operating revenue fell 6.1% to $8.08 billion, missing analysts' estimate of $8.22 billion, according to IBES data from Refinitiv.
Shares of the company were marginally up at $4.84 in trading before the bell. (Reporting by Neha Malara in Bengaluru' Editing by Arun Koyyur)
