Fraud and security issues cause considerable problems within mobile network operators. Security breaches are not only annoying: cleaning up the dirt goes along with considerable loss of time, revenue, subscriber trust and, at the end of the day, MNOs suffer the deterioration of the brand and their reputation. However, fraud prevention and security is anything but a predicament. To anyone willing to improve further, our experts at RoamsysNext can be of use with the means at their hands: data, knowledge, and experience.

It is no secret that telecom fraud is a fast-growing field. Isn’t it a cutting-edge and, at the same time, low-risk alternative to traditional crime methods such as mugging or robbing a bank? All joking aside, with the abuse of telecom products or services, considerable amounts of cash are transferred from the customer or carrier accounts right into the pockets of the attackers. Is it pocket money though? According to a 2019 report by Europol’s European Cybercrime Centre (EC3), fraud costs the telecom industry estimated €10.6 billion (US$ 12 billion) per year (other estimates range from 3-10 percent of the MNOs gross revenues).

Cost of churn

Fraud causes considerable problems within MNOs. Not only with the loss of revenue, but it consumes valuable time and effort to repair the damage on multiple fronts. In the end, MNOs suffer from the deterioration of their brand and their reputation. We all know too well: it takes so much more time, money and effort to win new customers than to nourish and cherish existing ones. Subscribers do not enjoy switching between operators as well. But if forced by loss of money, loss of personal data and unnerving amounts of time spent recovering data, who would not lose trust and switch to a competitor?
As a person in charge for fraud prevention and security, you don’t want to always have to clean up the mess, you want to take the fight to the fraudsters!

We at RoamsysNext relentlessly strive to help our customers to prosperity

Who answers for these damages? Time for outrage: the telecom companies pay for the costs of fraud themselves! Although there is quite a bit of cross-border cooperation on stopping fraud, investigations take their time. MNOs are investing continuously in protection from fraudsters. Annoyingly, most efforts concentrate on damage limitation after attacks have already taken place. Even if it does not matter whether or not all types of wrongful or improper activity performed against a mobile network are considered criminal in every country of the world. Any kind of help by intelligence sharing and providing additional information for correlation and verification of information would be welcome.

Taking up the fight

We at RoamsysNext are also very passionate about our customers, and relentlessly strive to help their prosperity. Over 120 customers in 90 countries already trust RoamsysNext’s product suite.
