I like to have this kind of lenovo. but then, before i came here..im google other forum and feedback from users. most of them are really dispointed with USSD code like, *118# (for celcom), *100# (for maxis). they said it cant be reach.  do you face the same problem? May i know whether this model got external storage (memory/sd card) slot (up to 32GB)? Some specs said yes. but some said no. 
One more thing, may u  share the shop name that u bought from? website/mobile contact/any information bout that shop. i think you get the better one. tenkiuuuu.
