I don't see Nayatel even going outside of ISB/RWP anywhere in the near future ... They've always remained within the ISB/RWP area, and I don't think they want to shift out ..
I was previously a Micronet customer, and remained one for like 5-6 years .. Micronet/Nayatel prefer quality over quantity ... so imo, unless they completely dominate the internet market in ISB/RWP area, they will never expand outside ..
