Don't think so, coverage is still lacking far behind compared to the big three telco.

even if YES offer better plans, people won't subscribe to it.

their service sucks

is there any coverage under LRT tunnel for YES?
U Mobile took years to have site inside the 4-5 underground stations

need review from real user not paid blogger.

Exactly.

Have seen some speedtest done by tech blogger, not very impressive but usable speeds.

been using yes for few years. i could get online in express bus from jb to kl, kl to bukit kayu hitam, with very little connection loss. in kl, i could use it from ampang park lrt till masjid jamek.

at home in ampang, where i could only get 2-3 bars in my living room, it still have very good speed.

btw, im using the huddle xs.

Where did you get? I went to yes store at 1Utama, they tell me not selling yet althought they have the sim display on the shop. I was told not for sale. 

The sales people attitude is very poor, don't bother, and not interested in doing business. That shows why company not earning.

Maybe kot..i'am using the prepaid starter pack..will test for one month..haish..

kl ok la.. Melaka ok, ipoh pun ok tgk tempat juga... Lte ok. Zaman wimax suck...

10 pcs new YES altitude 2 just arrived in my shop this afternoon 

should be. i can use the LTE no problem and its an iphone 12 msia set. dont see an issue why it cant be supported

EDI: just checked their FAQ and it seems that iphone only supports it as data sim only so no text / call. lame, waste my rm1. Can't use it to register my dota account hahaha

point no.20

LOLZ

lucky i didnt active my simcard yet

Because Apple did not verify Yes and hence it was not added to the supported network list by Apple. There had been speculation that Apple is pressuring carrier into offering iPhone devices bundle before certifying the particular network.

bought it month ago from shopee cos only RM1,
until now still haven't active it,
just leave it there

Which telco you wanna port out to.
I have another line, Hotlink and yes it's also slow.
Worse still my area very difficult to get 4G signal. Spend most of the time H+.
If I enable LTE only mode, nobody can call me. Cause stingy and selfish Maxis only limit VOLTE to its Posptaid users.

Sorry if I whine about Hotlink, because I'm thankful my Yes 4G is not affected
