jasa sometimes ride on celcom...
better try unifi prepaid 1st to confirm

look for signal indicator
4G LTE is unifi, 3G is celcom

I am the one out of coverage. but i have unifi mobile before.

One thing is upload will slow a bit......

Just subscribed yesterday with contract for 24month that includes B618 4G Router. My home is out of blue coverage area about 4km(approximately). Manage to get 1bar signal with speed up to 15mbps. I'm satisfied with this spec since other telco that offer unlimited plan is congested in my area. Gonna tune external antenna to get better coverage later.

Edit : Forgot to mention I lock Band 40. Band 5 & band 38 signal is everywhere but use 5mhz spectrum that always congested. Band 40 is for Unifi Air. Unifi Mobile usually will utilise band 5 & 38. That is why coverage map in Unifi Air page is smaller.

Basically, JASA pack and unifi air coverage is the same, the only difference is Band allocation. Jasa to utilize band 5. It is written somewhere in the T&C agreement when u sign up for it, I've seen it. However, if u have the capability to lock band signal (rooted phone or modem), you can do that. Unifi air utilize band 40.

During my application unifi air, TM staff did not check may location. She just ask whether I am aware of the coverage or not. 1st I said I want to try to get sim only and modem(contract) later, but she told me that I would have to sign up new account for that (with another RM100 deposit). Then I just straight to get 24m contract for the Huawei B618 instead.

using b525 too.


Move around outdoor and try or change band 5 or 38
if bad, I suggest u try other telcos

The signal is too poor, not worth the money.

same case as you
