I think it is a good news that the AIS and DTAC has been an agreement shared some telecom tower. Make both the network service user benefit as well as those who are far away, they will have the opportunity to use the more comprehensive telephone signals. I am the one of the people who use the services of the dtac network. I think that it is redundant to have the telecom tower in the same area. Each telephone network will not have to invest in creating new telecom tower in the same area.they should invest to build the telecom towers in the new area , That makes the telecom tower are even more effective. the network of AIS and Dtac can be used across the country even more.
