Unless you have tried all 3 telcos above.

I guess Maxis   

based of forummers testing, Maxis 4G is faster than Digi

not sure, if got test all 3.

what I know maxis 2x faster compare with Digi 

Here is the answer for you

at the end of the day..without independent research..we will never know..each telco also claimed they have the widest LTE coverage..but no concrete evidences..

As long as the place that you travel frequntly is come with good quality 4G coverage, it shouldn't be an issue..

You may refer to this link to check on the discussion on 4G LTE related topic as well: https://forum.lowyat.net/topic/3781351

As far as I know.. Maxis is the first and only 1 telco which offer 4G + or LTE Advance now in Malaysia, however, they are still in testing phase and offer at selected location only, and Bandar Sunway is one of it..

The average download speed I get from Maxis at my area is 60Mbps to 100Mbps.. which is much faster than the others like Digi and Celcom..

However, the issue now will be the price and quota..

Here is the speed I got under Maxis 4G + at my area yesterday

I have contacted Maxis, Celcom and Digi customer care yesterday.. and as per information I got, Maxis is the only telco which offer 4G + / LTE Advance now is Malaysia... or you may contact Digi again to reconfirm on this

For me $$$ is the difference....Maxis, Digi and CELCOM, I will go for Celcom!

Cheap, data can carry forward and 4G coverage is good too!

Think of yourself: What if you got 4G+ or LTE-A but your quota just 2 to 4GB? Bullshit! I prefer lesser speed (say 4G or H+) of 2 - 4GB quota!

This is what I get when I use Celcom 4G in my area (home) in Kota Damansara.

Celcom is not that bad though. It still one of the fastest 4G in Malaysia. I got plenty more result which surprisingly fast in other places especially in PJ. Coverage also better wherever I go I get 4G signal
