I tried to subscribe to 4mbps ages ago, but was told my area can't support it. But my dad just got a call saying someone will come to my house at 6pm later today. Checked at https://mips.tm.net.my/SelfCare/CheckUpgrad...130&verify=true saw it's being processed while before it shows not applicable or something. Crap!

If I subscribed to the 4mb line, will I be able to upgrade to HSBB later on or do I have to stay with 4mbps for 12-24 months contract?
