The average person can expect to pay between $250 and $300 a month for a mobile phone, according to a report by telecoms firm Telefonica.
That’s up from $150 a month last year.
But a recent report from research firm iResearch International found that the average US household could be paying $4,200 a year for a smartphone.
In addition to phone bills, the report also shows the cost of data plans, including monthly data plans and voice plans, which can include calls and texts.
Telefonica, which is part of the Spanish telecoms giant Telefónica, said the average smartphone user pays between $20 and $30 a month.
According to iResearch, the average American household has around 12GB of data on their smartphone, and the average person has 3GB of free data, which includes texts and calls.
The average monthly data plan on the iPhone costs $80 a month, with $20 for voice and $5 for data, according the report.
iPhone 4s costs $599, while the Samsung Galaxy S5 costs $749.
This isn’t the first time that the price of a smartphone has come under scrutiny.
Last year, it was revealed that an iPhone 6 Plus cost an average of $2,100, according a report from TechRadar.
But the cost has been declining in recent years.
In 2015, iPhone 5s cost $650.
That same year, Samsung Galaxy Note5 cost $849.
In 2016, iPhone 6 cost $599 and Samsung Galaxy Tab 6 cost about $799.
As you can see in the chart above, the price is dropping faster than the cost per gigabyte of data.
It is important to note that this isn’t a complete breakdown of the price per gigabit of data, or the cost to access the internet, as many people are using different types of internet.
