i cant send mms and use internet on my n73.....already got the settings from celcom, i only can use video call, voice call and sms....what could be the problem yah?

i think ive deleted before, ive even upgraded my firmware and didnt backup any setting, and after requesting the new settings, it still the same..... any other idea?

em2...ill go to celcom centre this saturday...is there any possibility that the problem lies in the sim card? because the last time when i register for this 1+3 package, all the sims are the same except mine, when the agent give out the sims to me, he suddenly saw my number is sabah number 019-8xx, and suddenly change my sim to other sim....hem2......
