Celcom internet is very damn slow even though im on full 4G network. I'm staying at Melawati and the internet is slow, if i go to Kajang also internet is slow. If i go to work at Kemaman, kota bahru, Kota Kinabalu, labuan, Miri, Bintulu also Internet is slow. It's feel like im living in 90s when everyone using 56K dial up modem. Customer service also is not efficient and unprofessional. I got fed up with their service. When im back at KL, i'll definitely port in to maxis eventhough a bit expensive but at least the network is fast. (i was on Maxis but port over to Celcom few months back)
