If you are more on data, Get Tunetalk, rm50 u can get 5gb internet per month, riding on celcom's network.

For tunetalk, there is a promo in which when you top up rm50, u get extra rm20 credit. Indirectly u pay rm50 you get rm70 credit to buy a 5gb internet. So far it's the cheapest internet in the market currently.

No idea my area no LTe, for 3G I think it's 100% identical to a celcom line. U can buy daily internet to test out first, starter pack is cheap also.
