The UK mobile industry seems to have a number of significant issues. The thing is that network operators fail to provide people with upfront cost of smartphones, which is paired with really long and expensive contracts. Thus, the “free of charge” phones are becoming a cornerstone of this industry in the country. However, the new O2 Refresh tariff will be able to become a possible solution of this problem. A representative of the company has made a statement that it will be a tariff, which will make contracts a lot more transparent.

The number of contract customers added in the quarter saw a 127 % increase on a year on year basis. The first nine months of also saw a decent increase in contract customers as the company added 679000 clients which was an increase of 155 % in comparison with the last year.

More than 18 million O2 customers from the UK will face this inconvenience from November, 28. Those who go to another continent for holidays will have to pay 40p instead of 25p for text messages, which is a 60 percent increase. In comparison to this, inner European tariffs fell in July, . A minute of voice communication costs 24p now and text messages are sent for 7p.
