guys want to ask.

I got my iphone 5 on May 6.

the problem is my phone network is not stable. its connects to 3G but sometimes the connections drops to no internet(same place)

and I think because of this, my battery is dying quite fast.

And I cant get LTE. I went to maxis store(menara Maxis) and put my phone next to the demo with LTE but my phone seems cant receive it.
I complain and the guy said my sim card is potong one so must get original nano sim card. It will cost me RM25

I dont think it is because of the sim card.

I gonna go back again there and ask to put the sim card from the demo phone into my phone and see if can receive LTE or not.

anyone face the same problem?

so it is really the nano sim problem is it? anyone faced the same problem before.

ok will change sim then. thank for the advices.
