is smart really blocks calls from sun cellular?

i think smart communications is really pissed off with sun cellular's unlimited service that they block some calls to their network, and delay sms with almost up to 6 to 8 hours.

yes, it's a fact that sun cellular congests their network starting at 4pm. and that is also the reason why smart and globe didn't continue their promos on buffet pricing to avoid network congestion. since sun is an upstart telco, they are very aggressive in expanding their network capacity and coverage.

the tests between sun and smart are supervise by ntc, and they found out that maybe smart is really blocking calls from sun with only 13 calls out of total of 44 came through. worst even text message is delayed not just 1 hour, but 6 to 8 hours.

"congestion may either be due to several factors such as call blocking and restriction. however, it is not conclusive to state that the calls are actually being constricted. this requires that tests must also be conducted on the other end of the interconnection link," the ntc report said.

smart legal and carrier business group head rogelio quevedo said in an earlier statement that sun cellular was just using those allegations of call blocking as a "scapegoat,'' considering that sun cellular's call connection rate was way below the ntc-mandated 93 percent.
