According to Citizens Advice reports, 130,000 consumers contacted the charity last year to seek advice regarding unexpectedly high mobile phone bills. In many cases, it was found that these bills are driving mobile users into serious debt.
In most cases, bill shocks happen when consumers take their phones abroad without realising that they will be charged higher data roaming charges. Other big reasons include billing and contract errors caused by mobile providers, as well as people falling victim to scams.
The charity revealed that more and more consumers are also getting caught out by smartphones that regularly connect to the net to check for emails. In addition, a large amount of mobile users are unaware of the fact that their providers will charge them for all calls that have been made until they report the loss of a stolen phone.
According to Citizens Advice Chief Executive Gillian Guy, 28,000 issues were reported to the charity in 2013. Along with the 102,000 users who sought help online, this indicates that people are experiencing a wide range of mobile phone contract issues.
"Mobile companies are hanging their customers out to dry with shock phone bills. Some people are facing bills of hundreds or thousands of pounds," he stated earlier this week.
"There is an opportunity for firms to be innovative by creating tools for people to keep day-to-day track of their charges, calls and data use. Consumers can also take steps to steer clear of running up a large bill abroad including checking costs with their network before they travel or getting a local Sim card if you visit a place regularly."
