RoamSim service is high quality GSM service that is provided with GSM carrier services of a well-established GSM operator of the U.K.

The user simply saves money without having to compromise on service quality expectation.

There are many spin-off benefits that result from the low-cost service. Consider the following:

  1. The user will answer every incoming call to RoamSim without concerns about costs. Imagine what it would do for business and for personal/family relationships when you can afford to speak as long as you like or need to with the caller.

    Business gets better productivity as business issues and problems can be dealt with in a timely fashion without the impediment due to telephone service cost consideration;  relationships are made current and improved with timely telephone communication – again without the impediment due to telephone service cost consideration

    Outbound calls can also be made at rates that are affordable as they are some 65%-85% lower than the roaming rates that are charged by the home-country GSM operator.

  2. The user can access at anytime to view  Call Details Records of his usage and account status with User Name (the  +44 Tel. No.) and Password (the PIN of the RoamSim) protection.

    In a corporation situation, the management can access the facility to view the telephone call activity of the traveling personnel.
