Revised landline telephone tariffs will be announced in a month, said the minister of communications and information technology.
Mahmoud Vaezi also told a press conference on Sunday that although everyone likes to see lower prices, several factors have been taken into account before announcing this year's new rates.
Vaezi hinted that calling ra tes will increase, ILNA reported.
"Regulating telephone tariffs will benefit both the telecoms sector and the people. An official statement will not be released until negotiations on this issue have been finalized," he said.
The minister weighed in on investment in the industry and said most new agreements have been made with private organizations, without specifying whether these are local or foreign.
"Several foreign firms have announced readiness for investing in Iran's fiber optics projects and new agreements will be finalized in the coming months," he said.
"Foreign mobile phone operators have also approached us to make new investments in this area."
Vaezi said a deadline has not been set by which Internet tariffs will reduce, though a committee has come together and is investigating the issue.
In an earlier interview, the minister had said Internet tariffs are likely to drop in the current Iranian year (started March 20).
He lauded advancements in this area and noted that the current state of Internet connectivity in Iran is incomparable to the initial state it had when the administration of President Hassan Rouhani took office in August 2013. "Currently, there are 20 and 10 million users of 3G and broadband Internet respectively," he said.
Referring to the Mobile Number Portability project, he said the project has progressed according to plan and "we are ready for launch".
Vaezi said all three mobile operators, namely Mobile Telecommunications Company of Iran (MCI or Hamrah-e-Aval), MTN Irancell and RighTel, are ready to launch MNP services that have been successfully tested.
