digi vs maxis

well, my title says it all...

so now i'm in a dilemma.. should i continue using digi.. or should i change to maxis???

well, the main reason i'm reluctant to change is because i dun like changing numbers... i'll always think "what if someone whom i havent contact many many years suddenly feel like giving me a call and cannot get me?"... lol i know this possibility is 0.1% but stilll.....!!!!

i dun really know exactly why suddenly i consider changing into maxis...

so now how??

maxis?? digi?? maxis?? digi?? arghhhhhhhhhhh
