Hi Esben

Although we haven't been in contact a lot has happend with my company since
then and we are today an enhanched reseller ( under our brand, with our
rating and a well good access to the company HLR ).

We are interetsed into looking into your SS7 USSD, SMSC And Mobile HLR
platforms.

We are wondering about costs surronding these platforms.
