I have a doubt regarding ‘roaming’. At present I am working for a tie-up with mobile operators in South east asian countries.
Actually, there were some problems with MTC. The operator is getting a REL message (Unable to route to the destination).
They were able to send me a trace. It shows ‘calling adress signals’ as ‘0019198xxxx’. ‘0091xxx’ is the code for India. What does 1 has to do between 00 & 91xxxx. When enquired they told me as some suffix. I am unsure about it. How to go about it?
